Minetest Mapper C++
===================
A port of minetestmapper.py to C++ from https://github.com/minetest/minetest/tree/master/util
Requirements
------------
* libgd
* sqlite3
* xxd binary (You can get xxd from your distribution packages or use '' wget -O xxd.c http://www.opensource.apple.com/source/vim/vim-43/vim/src/xxd/xxd.c?txt && gcc xxd.c -o xxd '')
Compilation
-----------
Plain:
::
cmake .
make
With levelDB support:
::
cmake -DENABLE_LEVELDB=true .
make
Debug version:
::
cmake -DCMAKE_BUILD_TYPE:STRING=Debug .
make
Release version:
::
cmake -DCMAKE_BUILD_TYPE:STRING=Release .
make
Usage
-----
Binary `minetestmapper` has two mandatory paremeters, `-i` (input world path)
and `-o` (output image path).
::
./minetestmapper -i ~/.minetest/worlds/my_world/ -o ~/map.png
Parameters
^^^^^^^^^^
bgcolor:
Background color of image, `--bgcolor #ffffff`
scalecolor:
Color of scale, `--scalecolor #000000`
playercolor:
Color of player indicators, `--playercolor #ff0000`
origincolor:
Color of origin indicator, `--origincolor #ff0000`
drawscale:
Draw tick marks, `--drawscale`
drawplayers:
Draw player indicators, `--drawplayers`
draworigin:
Draw origin indicator, `--draworigin`
noshading:
Don't draw shading on nodes, `--noshading`
min-y:
Don't draw nodes below this y value, `--min-y -25`
max-y:
Don't draw nodes above this y value, `--max-y 75`
backend:
Use specific map backend, supported: sqlite3, leveldb, `--backend leveldb`
geometry:
Limit area to specific geometry, `--geometry -800:-800+1600+1600`
forcegeometry:
Generate a map of the requested size, even if the world is smaller.
sqlite-cacheworldrow:
When using sqlite, read an entire world row at one, instead of reading
one block at a time.
This may improve performance when a large percentage of the world is mapped.
verbose:
report some useful/ interesting information:
* maximum coordinates of the world
* world coordinates included the map being generated
* number of blocks: in the world, and in the map area.
* database access statistics.
Customization of colors.txt
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Default `colors.txt` is included in binary. Color definitions can be redefined
using external `colors.txt` file.
