## Script for automatic building of Minetest for OS X from GitHub
[Binaries made with this are available here](https://github.com/mdoege/minetest/releases)
### Usage
bash make_mac.sh
This will create a ZIP file in releases/ with an app bundle.
### General hints for using GitHub
You cannot just go to the GitHub page and right click the script and do "save as...". This just saves the html page with the script. The entire folder provided on the GitHub page is required. Download the [zip file](https://github.com/mdoege/mtmake-osx/archive/master.zip), extract it, navigate inside it with a terminal and type ./make_mac.sh. The zip file with the application can be found in the "releases" folder.
### How it works
The script
* updates Minetest OS X executable and shared files
* does not change libraries (which is why a previous version of minetest.app with its modified dynamic libraries is included)
### Dependencies
Install with [Homebrew](http://brew.sh/) ("brew install"): cmake, freetype, gettext, hiredis, irrlicht, jpeg, leveldb, libogg, libvorbis, luajit
(snappy and libpng will get installed by brew automatically too.)
You also need Xcode 5 and the Xcode Command Line Tools. (You should get prompted for installation of the latter if you run the build script for the first time.)
(Optionally you can install XQuartz for X11 support.)
### Playing the game
* Use two finger tap for right click
* Use "e" for sneak/climb down (activate in 'Settings -> Change keys')
* If you would like to start the Minetest server from a terminal, run "/Applications/minetest.app/Contents/Resources/bin/minetest --server".
### How to update dynamic libraries (rarely needed)
The "build_libs.sh" script in releases will rebuild the libs folder.
However here are some explanations for how to do this manually.
This will create the libs directory and change library path names:
dylibbundler -x minetest.app/Contents/Resources/bin/minetest -b -d ./minetest.app/Contents/libs/ \
-p @executable_path/../../libs/ -cd
(Note that this only works with an unmodified minetet binary that has not had its own link s changed by e.g. the dylibbundler invocation in make_mac.sh itself.)
Check if all no libraries point to Homebrew Cellar direcory any more:
$ for x in *.dylib ; do otool -L $x|grep Cell; done
Update a library reference that was not updated by dylibbundler with:
$ install_name_tool -change /usr/local/Cellar/libvorbis/1.3.4/lib/libvorbis.0.dylib \
@executable_path/../../libs/libvorbis.0.dylib libvorbisfile.3.dylib

Minetest
============
An InfiniMiner/Minecraft inspired game.
Copyright (c) 2010-2013 Perttu Ahola <celeron55@gmail.com>
and contributors (see source file comments and the version control log)
In case you downloaded the source code:
---------------------------------------
If you downloaded the Minetest Engine source code in which this file is
contained, you probably want to download the minetest_game project too:
https://github.com/minetest/minetest_game/
See the README.txt in it.
Further documentation
----------------------
- Website: http://minetest.net/
- Wiki: http://wiki.minetest.net/
- Developer wiki: http://dev.minetest.net/
- Forum: http://forum.minetest.net/
- Github: https://github.com/minetest/minetest/
- doc/ directory of source distribution
This game is not finished
--------------------------
- Don't expect it to work as well as a finished game will.
- Please report any bugs. When doing that, debug.txt is useful.
Default Controls
-----------------
- WASD: move
- Space: jump/climb
- Shift: sneak/go down
- Q: drop item
- I: inventory
- Mouse: turn/look
- Mouse left: dig/punch
- Mouse right: place/use
- Mouse wheel: select item
- Esc: pause menu
- T: chat
- Settable in the configuration file, see the section below.
Paths
------
$bin - Compiled binaries
$share - Distributed read-only data
$user - User-created modifiable data
Windows .zip / RUN_IN_PLACE source:
$bin = bin
$share = .
$user = .
Linux installed:
$bin = /usr/bin
$share = /usr/share/minetest
$user = ~/.minetest
OS X:
$bin = ?
$share = ?
$user = ~/Library/Application Support/minetest
World directory
----------------
- Worlds can be found as separate folders in:
$user/worlds/
Configuration file:
-------------------
- Default location:
$user/minetest.conf
- It is created by Minetest when it is ran the first time.
- A specific file can be specified on the command line:
--config <path-to-file>
Command-line options:
---------------------
- Use --help
Compiling on GNU/Linux:
-----------------------
Install dependencies. Here's an example for Debian/Ubuntu:
$ apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev libogg-dev libvorbis-dev libopenal-dev libcurl4-gnutls-dev libfreetype6-dev
Download source, extract (this is the URL to the latest of source repository, which might not work at all times):
$ wget https://github.com/minetest/minetest/tarball/master -O master.tar.gz
$ tar xf master.tar.gz
$ cd minetest-minetest-286edd4 (or similar)
Download minetest_game (otherwise only the "Minimal development test" game is available)
$ cd games/
$ wget https://github.com/minetest/minetest_game/tarball/master -O minetest_game.tar.gz
$ tar xf minetest_game.tar.gz
$ mv minetest-minetest_game-* minetest_game
$ cd ..
Build a version that runs directly from the source directory:
$ cmake . -DRUN_IN_PLACE=1
$ make -j2
Run it:
$ cd bin
$ ./minetest
- Use cmake . -LH to see all CMake options and their current state
- If you want to install it system-wide (or are making a distribution package), you will want to use -DRUN_IN_PLACE=0
- You can build a bare server or a bare client by specifying -DBUILD_CLIENT=0 or -DBUILD_SERVER=0
- You can select between Release and Debug build by -DCMAKE_BUILD_TYPE=<Debug or Release>
- Debug build is slower, but gives much more useful output in a debugger
- If you build a bare server, you don't need to have Irrlicht installed. In that case use -DIRRLICHT_SOURCE_DIR=/the/irrlicht/source

Compiling on Windows:
---------------------
- This section is outdated. In addition to what is described here:
- In addition to minetest, you need to download minetest_game.
- If you wish to have sound support, you need libogg, libvorbis and libopenal
- You need:
* CMake:
http://www.cmake.org/cmake/resources/software.html
* MinGW or Visual Studio
http://www.mingw.org/
http://msdn.microsoft.com/en-us/vstudio/default
* Irrlicht SDK 1.7:
http://irrlicht.sourceforge.net/downloads.html
* Zlib headers (zlib125.zip)
http://www.winimage.com/zLibDll/index.html
* Zlib library (zlibwapi.lib and zlibwapi.dll from zlib125dll.zip):
http://www.winimage.com/zLibDll/index.html
* Optional: gettext library and tools:
http://gnuwin32.sourceforge.net/downlinks/gettext.php
- This is used for other UI languages. Feel free to leave it out.
* And, of course, Minetest:
http://minetest.net/download.php
- Steps:
- Select a directory called DIR hereafter in which you will operate.
- Make sure you have CMake and a compiler installed.
- Download all the other stuff to DIR and extract them into there.
("extract here", not "extract to packagename/")
NOTE: zlib125dll.zip needs to be extracted into zlib125dll
- All those packages contain a nice base directory in them, which
should end up being the direct subdirectories of DIR.
- You will end up with a directory structure like this (+=dir, -=file):
-----------------
+ DIR
- zlib-1.2.5.tar.gz
- zlib125dll.zip
- irrlicht-1.7.1.zip
- 110214175330.zip (or whatever, this is the minetest source)
+ zlib-1.2.5
- zlib.h
+ win32
...
+ zlib125dll
- readme.txt
+ dll32
...
+ irrlicht-1.7.1
+ lib
+ include
...
+ gettext (optional)
+bin
+include
+lib
+ minetest
+ src
+ doc
- CMakeLists.txt
...
-----------------
- Start up the CMake GUI
- Select "Browse Source..." and select DIR/minetest
- Now, if using MSVC:
- Select "Browse Build..." and select DIR/minetest-build
- Else if using MinGW:
- Select "Browse Build..." and select DIR/minetest
- Select "Configure"
- Select your compiler
- It will warn about missing stuff, ignore that at this point. (later don't)
- Make sure the configuration is as follows
(note that the versions may differ for you):
-----------------
BUILD_CLIENT [X]
BUILD_SERVER [ ]
CMAKE_BUILD_TYPE Release
CMAKE_INSTALL_PREFIX DIR/minetest-install
IRRLICHT_SOURCE_DIR DIR/irrlicht-1.7.1
RUN_IN_PLACE [X]
WARN_ALL [ ]
ZLIB_DLL DIR/zlib125dll/dll32/zlibwapi.dll
ZLIB_INCLUDE_DIR DIR/zlib-1.2.5
ZLIB_LIBRARIES DIR/zlib125dll/dll32/zlibwapi.lib
GETTEXT_BIN_DIR DIR/gettext/bin
GETTEXT_INCLUDE_DIR DIR/gettext/include
GETTEXT_LIBRARIES DIR/gettext/lib/intl.lib
GETTEXT_MSGFMT DIR/gettext/bin/msgfmt
-----------------
- Hit "Configure"
- Hit "Configure" once again 8)
- If something is still coloured red, you have a problem.
- Hit "Generate"
If using MSVC:
- Open the generated minetest.sln
- The project defaults to the "Debug" configuration. Make very sure to
select "Release", unless you want to debug some stuff (it's slower
and might not even work at all)
- Build the ALL_BUILD project
- Build the INSTALL project
- You should now have a working game with the executable in
DIR/minetest-install/bin/minetest.exe
- Additionally you may create a zip package by building the PACKAGE
project.
If using MinGW:
- Using the command line, browse to the build directory and run 'make'
(or mingw32-make or whatever it happens to be)
- You may need to copy some of the downloaded DLLs into bin/, see what
running the produced executable tells you it doesn't have.
- You should now have a working game with the executable in
DIR/minetest/bin/minetest.exe

-- Generic implementation of a filter/sortable list --
-- Usage: --
-- Filterlist needs to be initialized on creation. To achieve this you need to --
-- pass following functions: --
-- raw_fct() (mandatory): --
-- function returning a table containing the elements to be filtered --
-- compare_fct(element1,element2) (mandatory): --
-- function returning true/false if element1 is same element as element2 --
-- uid_match_fct(element1,uid) (optional) --
-- function telling if uid is attached to element1 --
-- filter_fct(element,filtercriteria) (optional) --
-- function returning true/false if filtercriteria met to element --
-- fetch_param (optional) --
-- parameter passed to raw_fct to aquire correct raw data --

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

=============================
Minetest World Format 22...25
=============================
This applies to a world format carrying the block serialization version
22...25, used at least in
- 0.4.dev-20120322 ... 0.4.dev-20120606 (22...23)
- 0.4.0 (23)
- 24 was never released as stable and existed for ~2 days
The block serialization version does not fully specify every aspect of this
format; if compliance with this format is to be checked, it needs to be
done by detecting if the files and data indeed follows it.
Legacy stuff
=============
Data can, in theory, be contained in the flat file directory structure
described below in Version 17, but it is not officially supported. Also you
may stumble upon all kinds of oddities in not-so-recent formats.
Files
======
Everything is contained in a directory, the name of which is freeform, but
often serves as the name of the world.
Currently the authentication and ban data is stored on a per-world basis.
It can be copied over from an old world to a newly created world.
World
|-- auth.txt ----- Authentication data
|-- env_meta.txt - Environment metadata
|-- ipban.txt ---- Banned ips/users
|-- map_meta.txt - Map metadata
|-- map.sqlite --- Map data
|-- players ------ Player directory
| |-- player1 -- Player file
| '-- Foo ------ Player file
`-- world.mt ----- World metadata
auth.txt
---------
Contains authentication data, player per line.
<name>:<password hash>:<privilege1,...>
Format of password hash is <name><password> SHA1'd, in the base64 encoding.
Example lines:
- Player "celeron55", no password, privileges "interact" and "shout":
celeron55::interact,shout
- Player "Foo", password "bar", privilege "shout":
foo:iEPX+SQWIR3p67lj/0zigSWTKHg:shout
- Player "bar", no password, no privileges:
bar::
env_meta.txt
-------------
Simple global environment variables.
Example content (added indentation):
game_time = 73471
time_of_day = 19118

ipban.txt
----------
Banned IP addresses and usernames.
Example content (added indentation):
123.456.78.9|foo
123.456.78.10|bar
map_meta.txt
-------------
Simple global map variables.
Example content (added indentation):
seed = 7980462765762429666

map.sqlite
-----------
Map data.
See Map File Format below.
player1, Foo
-------------
Player data.
Filename can be anything.
See Player File Format below.
world.mt
---------

Player File Format
===================
- Should be pretty self-explanatory.
- Note: position is in nodes * 10
Example content (added indentation):
hp = 11

Map File Format
================
Minetest maps consist of MapBlocks, chunks of 16x16x16 nodes.
In addition to the bulk node data, MapBlocks stored on disk also contain
other things.
History
--------
We need a bit of history in here. Initially Minetest stored maps in a
format called the "sectors" format. It was a directory/file structure like
this:
sectors2/XXX/ZZZ/YYYY
For example, the MapBlock at (0,1,-2) was this file:
sectors2/000/ffd/0001
Eventually Minetest outgrow this directory structure, as filesystems were
struggling under the amount of files and directories.
Large servers seriously needed a new format, and thus the base of the
current format was invented, suggested by celeron55 and implemented by
JacobF.
SQLite3 was slammed in, and blocks files were directly inserted as blobs
in a single table, indexed by integer primary keys, oddly mangled from
coordinates.
Today we know that SQLite3 allows multiple primary keys (which would allow
storing coordinates separately), but the format has been kept unchanged for
that part. So, this is where it has come.
</history>
So here goes
-------------
map.sqlite is an sqlite3 database, containg a single table, called
"blocks". It looks like this:
CREATE TABLE `blocks` (`pos` INT NOT NULL PRIMARY KEY,`data` BLOB);
The key
--------
"pos" is created from the three coordinates of a MapBlock using this
algorithm, defined here in Python:
def getBlockAsInteger(p):
return int64(p[2]*16777216 + p[1]*4096 + p[0])
def int64(u):
while u >= 2**63:
u -= 2**64
while u <= -2**63:
u += 2**64
return u
It can be converted the other way by using this code:
def getIntegerAsBlock(i):
x = unsignedToSigned(i % 4096, 2048)
i = int((i - x) / 4096)
y = unsignedToSigned(i % 4096, 2048)
i = int((i - y) / 4096)
z = unsignedToSigned(i % 4096, 2048)
return x,y,z
def unsignedToSigned(i, max_positive):
if i < max_positive:
return i
else:
return i - 2*max_positive
The blob
---------
The blob is the data that would have otherwise gone into the file.
See below for description.
MapBlock serialization format
==============================
NOTE: Byte order is MSB first (big-endian).
NOTE: Zlib data is in such a format that Python's zlib at least can
directly decompress.
u8 version
- map format version number, this one is version 22
u8 flags
- Flag bitmasks:
- 0x01: is_underground: Should be set to 0 if there will be no light
obstructions above the block. If/when sunlight of a block is updated
and there is no block above it, this value is checked for determining
whether sunlight comes from the top.
- 0x02: day_night_differs: Whether the lighting of the block is different
on day and night. Only blocks that have this bit set are updated when
day transforms to night.
- 0x04: lighting_expired: If true, lighting is invalid and should be
updated. If you can't calculate lighting in your generator properly,
you could try setting this 1 to everything and setting the uppermost
block in every sector as is_underground=0. I am quite sure it doesn't
work properly, though.
- 0x08: generated: True if the block has been generated. If false, block
is mostly filled with CONTENT_IGNORE and is likely to contain eg. parts
of trees of neighboring blocks.
u8 content_width
- Number of bytes in the content (param0) fields of nodes
if map format version <= 23:
- Always 1
if map format version >= 24:
- Always 2
u8 params_width
- Number of bytes used for parameters per node
- Always 2
zlib-compressed node data:
if content_width == 1:
- content:
u8[4096]: param0 fields
u8[4096]: param1 fields
u8[4096]: param2 fields
if content_width == 2:
- content:
u16[4096]: param0 fields
u8[4096]: param1 fields
u8[4096]: param2 fields
- The location of a node in each of those arrays is (z*16*16 + y*16 + x).
zlib-compressed node metadata list
- content:
u16 version (=1)
u16 count of metadata
foreach count:
u16 position (p.Z*MAP_BLOCKSIZE*MAP_BLOCKSIZE + p.Y*MAP_BLOCKSIZE + p.X)
u16 type_id
u16 content_size
u8[content_size] (content of metadata)
- Node timers
if map format version == 23:
u8 unused version (always 0)
if map format version == 24: (NOTE: Not released as stable)
u8 nodetimer_version
if nodetimer_version == 0:
(nothing else)
if nodetimer_version == 1:
u16 num_of_timers
foreach num_of_timers:
u16 timer position (z*16*16 + y*16 + x)
s32 timeout*1000
s32 elapsed*1000
u8 static object version:
- Always 0
u16 static_object_count
foreach static_object_count:
u8 type (object type-id)
s32 pos_x_nodes * 10000
s32 pos_y_nodes * 10000
s32 pos_z_nodes * 10000
u16 data_size
u8[data_size] data
u32 timestamp
- Timestamp when last saved, as seconds from starting the game.
- 0xffffffff = invalid/unknown timestamp, nothing should be done with the time
difference when loaded
u8 name-id-mapping version
- Always 0
u16 num_name_id_mappings
foreach num_name_id_mappings
u16 id
u16 name_len
u8[name_len] name
- Node timers
if map format version == 25:
u8 length of the data of a single timer (always 2+4+4=10)
u16 num_of_timers
foreach num_of_timers:
u16 timer position (z*16*16 + y*16 + x)
s32 timeout*1000
s32 elapsed*1000
EOF.
Format of nodes
----------------
A node is composed of the u8 fields param0, param1 and param2.
if map format version <= 23:
The content id of a node is determined as so:
- If param0 < 0x80,
content_id = param0
- Otherwise
content_id = (param0<<4) + (param2>>4)
if map format version >= 24:
The content id of a node is param0.
The purpose of param1 and param2 depend on the definition of the node.
The name-id-mapping
--------------------
The mapping maps node content ids to node names.
Node metadata format
---------------------
1: Generic metadata

eg. 'default:pick_wood 21323'
eg. '"default:apple" 2'
eg. 'default:apple'
- The wear value in tools is 0...65535
- There are also a number of older formats that you might stumble upon:
eg. 'node "default:dirt" 5'
eg. 'NodeItem default:dirt 5'
eg. 'ToolItem WPick 21323'
Inventory serialization format
-------------------------------
- The inventory serialization format is line-based
- The newline character used is "\n"
- The end condition of a serialized inventory is always "EndInventory\n"
- All the slots in a list must always be serialized.
Example (format does not include "---"):
---
List foo 4
Item default:sapling
Item default:sword_stone 1 10647
Item default:dirt 99
Empty
EndInventoryList
List bar 9
Empty
Empty
Empty
Empty
Empty
Empty
Empty
Empty
Empty
EndInventoryList
EndInventory
---
==============================================
Minetest World Format used as of 2011-05 or so
==============================================
Map data serialization format version 17.
0.3.1 does not use this format, but a more recent one. This exists here for
historical reasons.
Directory structure:
sectors/XXXXZZZZ or sectors2/XXX/ZZZ
XXXX, ZZZZ, XXX and ZZZ being the hexadecimal X and Z coordinates.
Under these, the block files are stored, called YYYY.
There also exists files map_meta.txt and chunk_meta, that are used by the
generator. If they are not found or invalid, the generator will currently
behave quite strangely.
The MapBlock file format (sectors2/XXX/ZZZ/YYYY):
-------------------------------------------------
NOTE: Byte order is MSB first.
u8 version
- map format version number, this one is version 17
u8 flags
- Flag bitmasks:
- 0x01: is_underground: Should be set to 0 if there will be no light
obstructions above the block. If/when sunlight of a block is updated and
there is no block above it, this value is checked for determining whether
sunlight comes from the top.
- 0x02: day_night_differs: Whether the lighting of the block is different on
day and night. Only blocks that have this bit set are updated when day
transforms to night.
- 0x04: lighting_expired: If true, lighting is invalid and should be updated.
If you can't calculate lighting in your generator properly, you could try
setting this 1 to everything and setting the uppermost block in every
sector as is_underground=0. I am quite sure it doesn't work properly,
though.
zlib-compressed map data:
- content:
u8[4096]: content types
u8[4096]: param1 values
u8[4096]: param2 values
zlib-compressed node metadata
- content:
u16 version (=1)
u16 count of metadata
foreach count:
u16 position (= p.Z*MAP_BLOCKSIZE*MAP_BLOCKSIZE + p.Y*MAP_BLOCKSIZE + p.X)
u16 type_id
u16 content_size
u8[content_size] misc. stuff contained in the metadata
u16 mapblockobject_count
- always write as 0.
- if read != 0, just fail.
foreach mapblockobject_count:
- deprecated, should not be used. Length of this data can only be known by
properly parsing it. Just hope not to run into any of this.
u8 static object version:
- currently 0
u16 static_object_count
foreach static_object_count:
u8 type (object type-id)
s32 pos_x * 1000
s32 pos_y * 1000
s32 pos_z * 1000
u16 data_size
u8[data_size] data
u32 timestamp
- Timestamp when last saved, as seconds from starting the game.
- 0xffffffff = invalid/unknown timestamp, nothing will be done with the time
difference when loaded (recommended)
Node metadata format:
---------------------
Sign metadata:
u16 string_len
u8[string_len] string
Furnace metadata:
TBD
Chest metadata:
TBD
Locking Chest metadata:

------------------------------------------------------------------
/*
=============================== NOTES ==============================
NOTE: Things starting with TODO are sometimes only suggestions.
NOTE: iostream.imbue(std::locale("C")) is very slow
NOTE: Global locale is now set at initialization
NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the
hardware buffer (it is not freed automatically)
NOTE: A random to-do list saved here as documentation:
A list of "active blocks" in which stuff happens. (+=done)
+ Add a never-resetted game timer to the server
+ Add a timestamp value to blocks
+ The simple rule: All blocks near some player are "active"
- Do stuff in real time in active blocks
+ Handle objects
- Grow grass, delete leaves without a tree
- Spawn some mobs based on some rules
- Transform cobble to mossy cobble near water
- Run a custom script
- ...And all kinds of other dynamic stuff
+ Keep track of when a block becomes active and becomes inactive
+ When a block goes inactive:
+ Store objects statically to block
+ Store timer value as the timestamp
+ When a block goes active:
+ Create active objects out of static objects
- Simulate the results of what would have happened if it would have
been active for all the time
- Grow a lot of grass and so on
+ Initially it is fine to send information about every active object
to every player. Eventually it should be modified to only send info
about the nearest ones.
+ This was left to be done by the old system and it sends only the
nearest ones.
NOTE: Seeds in 1260:6c77e7dbfd29:
5721858502589302589:
Spawns you on a small sand island with a surface dungeon
2983455799928051958:
Enormous jungle + a surface dungeon at ~(250,0,0)
Old, wild and random suggestions that probably won't be done:
-------------------------------------------------------------
SUGG: If player is on ground, mainly fetch ground-level blocks
SUGG: Expose Connection's seqnums and ACKs to server and client.
- This enables saving many packets and making a faster connection
- This also enables server to check if client has received the
most recent block sent, for example.
SUGG: Add a sane bandwidth throttling system to Connection
SUGG: More fine-grained control of client's dumping of blocks from
memory
- ...What does this mean in the first place?
SUGG: A map editing mode (similar to dedicated server mode)
SUGG: Transfer more blocks in a single packet
SUGG: A blockdata combiner class, to which blocks are added and at
destruction it sends all the stuff in as few packets as possible.
SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
it by sending more stuff in a single packet.
- Add a packet queue to RemoteClient, from which packets will be
combined with object data packets
- This is not exactly trivial: the object data packets are
sometimes very big by themselves
- This might not give much network performance gain though.
SUGG: Precalculate lighting translation table at runtime (at startup)
- This is not doable because it is currently hand-made and not
based on some mathematical function.
- Note: This has been changing lately
SUGG: A version number to blocks, which increments when the block is
modified (node add/remove, water update, lighting update)
- This can then be used to make sure the most recent version of
a block has been sent to client, for example
SUGG: Make the amount of blocks sending to client and the total
amount of blocks dynamically limited. Transferring blocks is the
main network eater of this system, so it is the one that has
to be throttled so that RTTs stay low.
SUGG: Meshes of blocks could be split into 6 meshes facing into
different directions and then only those drawn that need to be
SUGG: Background music based on cellular automata?
http://www.earslap.com/projectslab/otomata
SUGG: Simple light color information to air
SUGG: Server-side objects could be moved based on nodes to enable very
lightweight operation and simple AI
- Not practical; client would still need to show smooth movement.
SUGG: Make a system for pregenerating quick information for mapblocks, so
that the client can show them as cubes before they are actually sent
or even generated.
SUGG: Erosion simulation at map generation time
- This might be plausible if larger areas of map were pregenerated
without lighting (which is slow)
- Simulate water flows, which would carve out dirt fast and
then turn stone into gravel and sand and relocate it.
- How about relocating minerals, too? Coal and gold in
downstream sand and gravel would be kind of cool
- This would need a better way of handling minerals, mainly
to have mineral content as a separate field. the first
parameter field is free for this.
- Simulate rock falling from cliffs when water has removed
enough solid rock from the bottom
SUGG: For non-mapgen FarMesh: Add a per-sector database to store surface
stuff as simple flags/values
- Light?
- A building?
And at some point make the server send this data to the client too,
instead of referring to the noise functions
- Ground height
- Surface ground type
- Trees?
Gaming ideas:
-------------
- Aim for something like controlling a single dwarf in Dwarf Fortress
- The player could go faster by a crafting a boat, or riding an animal
- Random NPC traders. what else?
Game content:
-------------
- When furnace is destroyed, move items to player's inventory
- Add lots of stuff
- Glass blocks
- Growing grass, decaying leaves
- This can be done in the active blocks I guess.
- Lots of stuff can be done in the active blocks.
- Uh, is there an active block list somewhere? I think not. Add it.
- Breaking weak structures
- This can probably be accomplished in the same way as grass
- Player health points
- When player dies, throw items on map (needs better item-on-map
implementation)
- Cobble to get mossy if near water
- More slots in furnace source list, so that multiple ingredients
are possible.
- Keys to chests?
- The Treasure Guard; a big monster with a hammer
- The hammer does great damage, shakes the ground and removes a block
- You can drop on top of it, and have some time to attack there
before he shakes you off
- Maybe the difficulty could come from monsters getting tougher in
far-away places, and the player starting to need something from
there when time goes by.
- The player would have some of that stuff at the beginning, and
would need new supplies of it when it runs out
- A bomb
- A spread-items-on-map routine for the bomb, and for dying players
- Fighting:
- Proper sword swing simulation
- Player should get damage from colliding to a wall at high speed
Documentation:
--------------
Build system / running:
-----------------------
Networking and serialization:
-----------------------------
SUGG: Fix address to be ipv6 compatible
User Interface:
---------------
Graphics:
---------
SUGG: Combine MapBlock's face caches to so big pieces that VBO
can be used
- That is >500 vertices
- This is not easy; all the MapBlocks close to the player would
still need to be drawn separately and combining the blocks
would have to happen in a background thread
SUGG: Make fetching sector's blocks more efficient when rendering
sectors that have very large amounts of blocks (on client)
- Is this necessary at all?
SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
animating them is easier.
SUGG: Option for enabling proper alpha channel for textures
TODO: Flowing water animation
TODO: A setting for enabling bilinear filtering for textures
TODO: Better control of draw_control.wanted_max_blocks
TODO: Further investigate the use of GPU lighting in addition to the
current one
TODO: Artificial (night) light could be more yellow colored than sunlight.
- This is technically doable.
- Also the actual colors of the textures could be made less colorful
in the dark but it's a bit more difficult.
SUGG: Somehow make the night less colorful
TODO: Occlusion culling
- At the same time, move some of the renderMap() block choosing code
to the same place as where the new culling happens.
- Shoot some rays per frame and when ready, make a new list of
blocks for usage of renderMap and give it a new pointer to it.
Configuration:
--------------
Client:
-------
TODO: Untie client network operations from framerate
- Needs some input queues or something
- This won't give much performance boost because calculating block
meshes takes so long
SUGG: Make morning and evening transition more smooth and maybe shorter
TODO: Don't update all meshes always on single node changes, but
check which ones should be updated
- implement Map::updateNodeMeshes() and the usage of it
- It will give almost always a 4x boost in mesh update performance.
- A weapon engine
- Tool/weapon visualization
FIXME: When disconnected to the menu, memory is not freed properly
TODO: Investigate how much the mesh generator thread gets used when
transferring map data
Server:
-------
SUGG: Make an option to the server to disable building and digging near
the starting position
FIXME: Server sometimes goes into some infinite PeerNotFoundException loop
* Fix the problem with the server constantly saving one or a few
blocks? List the first saved block, maybe it explains.
- It is probably caused by oscillating water
- TODO: Investigate if this still happens (this is a very old one)
* Make a small history check to transformLiquids to detect and log
continuous oscillations, in such detail that they can be fixed.
FIXME: The new optimized map sending doesn't sometimes send enough blocks
from big caves and such
FIXME: Block send distance configuration does not take effect for some reason
Environment:
------------
TODO: Add proper hooks to when adding and removing active blocks
TODO: Finish the ActiveBlockModifier stuff and use it for something
Objects:
--------
TODO: Get rid of MapBlockObjects and use only ActiveObjects
- Skipping the MapBlockObject data is nasty - there is no "total
length" stored; have to make a SkipMBOs function which contains
enough of the current code to skip them properly.
SUGG: MovingObject::move and Player::move are basically the same.
combine them.
- NOTE: This is a bit tricky because player has the sneaking ability
- NOTE: Player::move is more up-to-date.
- NOTE: There is a simple move implementation now in collision.{h,cpp}
- NOTE: MovingObject will be deleted (MapBlockObject)
TODO: Add a long step function to objects that is called with the time
difference when block activates
Map:
----
TODO: Flowing water to actually contain flow direction information
- There is a space for this - it just has to be implemented.
TODO: Consider smoothening cave floors after generating them
TODO: Fix make_tree, make_* to use seed-position-consistent pseudorandom
- delta also
Misc. stuff:
------------
TODO: Make sure server handles removing grass when a block is placed (etc)
- The client should not do it by itself
- NOTE: I think nobody does it currently...
TODO: Block cube placement around player's head
TODO: Protocol version field
TODO: Think about using same bits for material for fences and doors, for
example
SUGG: Restart irrlicht completely when coming back to main menu from game.
- This gets rid of everything that is stored in irrlicht's caches.
- This might be needed for texture pack selection in menu
TODO: Merge bahamada's audio stuff (clean patch available)
Making it more portable:
------------------------
Stuff to do before release:
---------------------------
Fixes to the current release:
-----------------------------
Stuff to do after release:

Minetest changelog
----------------------
This should contain all the major changes.
For minor stuff, refer to the commit log of the repository.
0.3.1: (released on 2011-11-09)
- Fix frustum culling (previous versions have rendered too much stuff that is not actually visible (about 180 degrees, while should have been more like 100.))
- Add occlusion culling (improves performance a lot)
- Add “3d clouds” on/off checkbox in main menu
- Add “opaque water” on/off checkbox
- Fix some random minor stuff
- Turn mipmapping off (This makes far-away textures a bit noisier but better looking)
- Add Command-line signal handler for Windows (contributed by SpeedProg)

Minetest protocol (incomplete, early draft):
Updated 2011-06-18
A custom protocol over UDP.
Integers are big endian.
Refer to connection.{h,cpp} for further reference.
Initialization:
- A dummy reliable packet with peer_id=PEER_ID_INEXISTENT=0 is sent to the server:
- Actually this can be sent without the reliable packet header, too, i guess,
but the sequence number in the header allows the sender to re-send the
packet without accidentally getting a double initialization.
- Packet content:
# Basic header
u32 protocol_id = PROTOCOL_ID = 0x4f457403
u16 sender_peer_id = PEER_ID_INEXISTENT = 0
u8 channel = 0
# Reliable packet header
u8 type = TYPE_RELIABLE = 3
u16 seqnum = SEQNUM_INITIAL = 65500
# Original packet header
u8 type = TYPE_ORIGINAL = 1
# And no actual payload.
- Server responds with something like this:
- Packet content:
# Basic header
u32 protocol_id = PROTOCOL_ID = 0x4f457403
u16 sender_peer_id = PEER_ID_INEXISTENT = 0
u8 channel = 0
# Reliable packet header
u8 type = TYPE_RELIABLE = 3
u16 seqnum = SEQNUM_INITIAL = 65500
# Control packet header
u8 type = TYPE_CONTROL = 0
u8 controltype = CONTROLTYPE_SET_PEER_ID = 1
u16 peer_id_new = assigned peer id to client (other than 0 or 1)
- Then the connection can be disconnected by sending:
- Packet content:
# Basic header
u32 protocol_id = PROTOCOL_ID = 0x4f457403
u16 sender_peer_id = whatever was gotten in CONTROLTYPE_SET_PEER_ID
u8 channel = 0
# Control packet header
u8 type = TYPE_CONTROL = 0
u8 controltype = CONTROLTYPE_DISCO = 3
- Here's a quick untested connect-disconnect done in PHP:
# host: ip of server (use gethostbyname(hostname) to get from a dns name)
# port: port of server
function check_if_minetestserver_up($host, $port)
{
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
$timeout = array("sec" => 1, "usec" => 0);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, $timeout);
$buf = "\x4f\x45\x74\x03\x00\x00\x00\x03\xff\xdc\x01";
socket_sendto($socket, $buf, strlen($buf), 0, $host, $port);
$buf = socket_read($socket, 1000);
if($buf != "")
{
# We got a reply! read the peer id from it.
$peer_id = substr($buf, 9, 2);
# Disconnect
$buf = "\x4f\x45\x74\x03".$peer_id."\x00\x00\x03";
socket_sendto($socket, $buf, strlen($buf), 0, $host, $port);
socket_close($socket);
return true;
}
return false;
}
- Here's a Python script for checking if a minetest server is up, confirmed working
#!/usr/bin/env python
import sys, time, socket
address = ""
port = 30000
if len(sys.argv) <= 1:
print("Usage: %s <address>" % sys.argv[0])
exit()
if ':' in sys.argv[1]:
address = sys.argv[1].split(':')[0]
try:
port = int(sys.argv[1].split(':')[1])
except ValueError:
print("Please specify a valid port")
exit()
else:
address = sys.argv[1]
try:
start = time.time()
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.settimeout(2.0)
buf = "\x4f\x45\x74\x03\x00\x00\x00\x01"
sock.sendto(buf, (address, port))
data, addr = sock.recvfrom(1000)
if data:
peer_id = data[12:14]
buf = "\x4f\x45\x74\x03" + peer_id + "\x00\x00\x03"
sock.sendto(buf, (address, port))
sock.close()
end = time.time()
print("%s is up (%0.5fms)" % (sys.argv[1],end-start))
else:
print("%s seems to be down " % sys.argv[1])
except:
print("%s seems to be down " % sys.argv[1])
