~ LazyJ, 2014_06_01
~~~~~~~~~~~~~~~~~~~~
List of Changes
~~~~~~~~~~~~~~~~~~~~
##### MapGen
I did *not* fix Snow's mapgen issue with "PlantLife" (another great, Minetest
standard) based mods. Mapgen stuff is far beyond my current skill level.
What little changes I did make were to switch-out Snow nodes that Minetest
now has as defaults (dirt_with_snow, snow, ice). My thoughts being that
texture packs and other mods that may use these nodes as recipe items are more
likely to support default nodes. I also added a line above and below in the
"mapgen.lua" file indicating where to put the comment symbols to
comment-out/disable Snow's mapgen. Mods based on VanessaE's excellent
"PlantLife" mod will not produce if Snow's mapgen is active.
*Snow's mapgen is active by default.*
I did not disable it, merely indicated were the comment symbols are
to be placed. To compensate for the loss of snow resources when Snow's mapgen
is disabled, I created crafting recipes that allows players to craft more
snow, ice, and moss. This not only encourages snow builds, but also allows
the players to create snow biomes where they want and whatever size they are
willing to make them.
##### Fixed
* Pine saplings are now replaced with tree trunks when the tree grows.
* Snowballs no longer pass through solid objects. Griefers can no
longer flood the interiors of builds by throwing snowballs through the
walls hoping to either leave a snowy mess inside or that a heat source
would melt the snow and flood the interior.
* Snowballs no longer destroy nodes when thrown at the sides.
* Falling snow no longer destroys nodes (same problem snowballs had).
* Snow bricks now, instead of disappearing like before, melt
into water sources.
* Christmas tree saplings once again will drop when pine needles
are harvested.
* Dirt_with_snow changes to dirt when a solid, non-light permeating
(sunlight_propagates) block is set on top of it.
##### Changed
* All snow and ice stuff (including the stairs, slabs, panels, and
microblocks) will freeze dirt and dirt_with_grass into dirt_with_snow.
* All snow and most ice stuff will freeze water into ice, including
the stairs, slabs, panels, and microblocks. The exception is the
full-sized ice blocks will *not* freeze water into ice.
* Snow brick texture reworked and based off of the default stone brick
texture (and less purple in the grout).
* Ice stuff is now semi-transparent.
* Christmas trees now have blinking lights that give off a
low level of light.
* Christmas tree stars now give off a high level of light and the
light can be punched on or off.
* Combined default snow and snowballs. Now snow can be
thrown (left-click) or placed (right-click).
* Snow stuff now has "snow" sounds instead of "grass" sounds.
* Melting - Full-sized snow blocks, snow brick, snow cobble, and ice
will melt into water sources. The down-side is this makes a big,
permanent mess. The up-side, this is a convenient way to carry water,
if buckets are disabled on your server, by keeping full-sized snow
stuff and ice blocks in your inventory to, later, melt where you
need water.
* Melting - Partial and small-sized blocks like snow (snowballs),
basic stairs and slabs for snow stuff and ice, and circular saw-made
snow stuff and ice things will melt into a water source for 2 seconds,
then switch from a water source to flowing water, and after a moment
the flowing water dries-up (small, temporary mess).
##### Added
* New block-type: "Snow Cobble". Just like regular cobble from regular
stone, snow cobble comes from digging snow blocks.
* All snow and ice blocks can be crafted into basic slabs and stairs.
The default slabs stack and change back into full-sized blocks
("More Blocks" slabs won't do this).
* Soft dependency on a recent release Calinou's MoreBlocks so all
snow and ice blocks are compatible with the circular saw. If you don't
have MoreBlocks installed, Snow will ignore the code for those fancy
blocks and use basic stairs and slabs instead.
* All snow and ice stuff works with the screwdriver.
* Crafting, recycling, and cooking recipes for snow blocks,
ice, and moss.
* Snow bricks craft-recycle back into 4 snow blocks.
* 2 snow blocks craft into 3 snow blocks. This is to make up
for when the mapgen for snow biomes is disabled.
* 2 snow cobble craft-recycle into 3 snow blocks.
* 4 pine needles craft into 1 moss
* Snow blocks, snow cobble, and snow bricks can be cooked in a
furnace to make ice.
* Snowballs can be thrown (left-click) to build up layers. After the
11th layer, the bottom 9 layers change into a snow block. At a very
close distance, throwing snowballs can be used as a technique to
build-up gradual slopes. If you have lots and lots of snow balls,
with rapid-fire throwing, you can, very briefly, "white-out" another
player's view if your aim is good enough to hit them in the face.
* Snowballs can be placed (right-click) but will not stack into
multiple layers. Just one layer only. Placing snow is more reliable
and accurate than throwing snow from a distance. By placing snow,
players are able to create their own, personal, snow biomes.
* Vertical clearance check for tree growth. The nine blocks above the
spot where the sapling is placed must be free and clear of all
obstructions or else the sapling will not be allowed to grow.
Griefers could place the saplings in builds and when the tree grows
it may not destroy nodes but it fills the available air space leaving
a mess for the build's owner to clean-up. Now the trees will only grow
inside if there is 9, free-and-clear spaces from floor to ceiling.
Because pine trees (and Christmas trees) will grow on any solid surface,
their saplings are handy to take with you when deep mining. Just before
you run out of tool wood, dig out a space large enough for a tree to
grow, plant a pine or Christmas tree sapling then place 2 torches on
either side, right next to the sapling. After the tree grows harvest
the trunk for tool wood, the leaves for short-run fuel in the furnace
and for saplings to renew your tool wood supply again.
* Aliases to help make WorldEdit and "give" commands easier:
"default_snow" = "default:snow"
"snowball" = "default:snow"
"snowballs" = "default:snow"
"snow_ball" = "default:snow"
"ice" = "default:ice"
"default_ice" = "default:ice"
"dirtwithsnow" = "default:dirt_with_snow"
"snowdirt" = "default:dirt_with_snow"
"snowydirt" = "default:dirt_with_snow"
"snowblocks" = "default:snowblock"
"snowbrick" = "snow:snow_brick"
"bricksnow" = "snow:snow_brick"
"snowbricks" = "snow:snow_brick"
"snowybricks" = "snow:snow_brick"
"snowcobble" = "snow:snow_cobble"
"snowycobble" = "snow:snow_cobble"
"cobblesnow" = "snow:snow_cobble"
~~~~~~
TODO
~~~~~~
Falling Snow:
* Add code to prevent snowfall from depositing snow on or near torches,
active furnaces, and lava.
* Add code to prevent snowfall from depositing snow on
'walkable = false' defined nodes.
Sled:
* Figure out why the player avatars remain in a seated position,
even after getting off the sled, if they flew while on the sled.
'default.player_set_animation', where is a better explanation for this and what
are it's available options?

INSTALL:
----------
Place this folder in your minetest mods folder.
(http://dev.minetest.net/Installing_Mods)
* After downloading, unzip the file.
* Rename the directory "minetest-mod-snow-master" to "snow"
* Copy the "snow" directory into either
../minetest/worlds/yourworld'sname/worldmods/
or
../minetest/mods/
* If you put "snow" in the ../minetest/mods/ directory, either
enable the mod from within Minetest's "Configure" button
(main menu, bottom right) or by adding this line to the
world's "world.mt" file:
load_mod_snow = true
NOTICE
While this mod is installed you may experience slow map loading while a snow biome is generated.
While this mod is installed you may experience slower map loading while a snow biome is generated.
USAGE:
-------
@ -32,58 +63,41 @@ There are nine biome types:
* Snowy
* Plain
Snow can be picked up and thrown as snowballs or crafted into snow blocks.
Snow can be picked up and thrown as snowballs or stacked into snow blocks.
Snow and ice melts when near warm blocks such as torches or igniters such as lava.
Snow blocks freeze water source blocks around them.
Moss can be found in the snow, when moss is placed near cobble it spreads.
Christmas trees can be found when digging pine needles.
Sleds allow for faster travel on snow.
CRAFTING:

MAPGEN_V7:
------------
If you are using minetest 0.4.8 or the latest dev version of minetest you can choose to generate a v7 map.
This option can be found when creating a new map from the menu.
Snow Biomes has support for this though you might need a couple other biomes too otherwise you will only spawn snow.
There are a couple of bugs and limitations with this such as no ice being generated at the moment.
Config file:
------------
After starting a game in minetest with snow mod, a config file will be placed in this folder that contains the various options for snow mod.
As admin you can use the /snow command in-game to make various changes.
UNINSTALL:
------------
Simply delete the folder snow from the mods folder.
CHANGELOG:
------------
Version 1.4

Most snow biomes are too small to provide enough snow as a building material and
still have enough landscape snow to create the wintry surroundings of a
snow village or castle. So I added this snowblock crafting recipe as a way for
players to increase their snow supply in small increments. I considered making
the output 9 but that would make it all too quick and easy (especially for griefers) to create lots
of snowblocks (and then use them to water-grief by melting the snow blocks).

LazyJ's Fork of Splizard's "Snow" Mod
by LazyJ
version: Umpteen and 7/5ths something or another.
2014_04_12
--======================================
--=================
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
THE LIST OF CHANGES I'VE MADE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Falling snow would destroy nodes it deposited snow on. I figured out that if
I switched the 'snow.place' with 'minetest.place_node' and increased the
y position by 2, then the nodes were nolonger destroyed and the snow
would start to pile up.
~~~~~~
TODO
~~~~~~
* Add code to prevent snowfall from depositing snow on or
near torches and lava.
* Add code to prevent snowfall from depositing snow on
'walkable = false' defined nodes.

--======================================
LazyJ's Fork of Splizard's "Snow" Mod
by LazyJ
version: Umpteen and 7/5ths something or another.
2014_04_12
--======================================
--=================
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
THE LIST OF CHANGES I'VE MADE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The HUD message that displayed when a player sat on the sled would not go away after the player
got off the sled. I spent hours on trial-and-error while reading the lua_api.txt and scrounging
the Internet for a needle-in-the-haystack solution as to why the hud_remove wasn't working.
Turns out Splizard's code was mostly correct, just not assembled in the right order.
The key to the solution was found in the code of leetelate's scuba mod:
http://forum.minetest.net/viewtopic.php?id=7175
* Changed the wording of the HUD message for clarity.
~~~~~~
TODO
~~~~~~
* Figure out why the player avatars remain in a seated position, even after getting off the sled,
if they flew while on the sled. 'default.player_set_animation', where is a better explanation
for this and what are it's available options?
* Go through, clean-up my notes and get them better sorted. Some are in the code, some are
scattered in my note-taking program. This "Oh, I'll just make a little tweak here and a
little tweak there" project has evolved into something much bigger and more complex
than I originally planned. :p ~ LazyJ
* find out why the sled disappears after rightclicking it ~ HybridDog

A note about default torches, melting, and "buildable_to = true" in default snow.
On servers where buckets are disabled, snow and ice stuff is used to set water for crops and
water stuff like fountains, pools, ponds, ect.. It is a common practice to set a default torch on
the snow placed where the players want water to be.
If you place a default torch *on* default snow to melt it, instead of melting the snow is
*replaced* by the torch. Using "buildable_to = false" would fix this but then the snow would no
longer pile-up in layers; the snow would stack like thin shelves in a vertical column.
I tinkered with the default torch's code (see below) to check for snow at the position and one
node above (layered snow logs as the next y position above) but default snow's
"buildable_to = true" always happened first. An interesting exercise to better learn how Minetest
works, but otherwise not worth it. If you set a regular torch near snow, the snow will melt
and disappear leaving you with nearly the same end result anyway. I say "nearly the same"
because if you set a default torch on layered snow, the torch will replace the snow and be
lit on the ground. If you were able to set a default torch *on* layered snow, the snow would
melt and the torch would become a dropped item.

This section of code that makes blocks compatible with MoreBlocks' circular saw.
I've added circular saw compatible code for default snowblocks and ice. :D
A big thanks to Calinou and ShadowNinja for making this possible.
Because StairsPlus creates partial blocks, it didn't seem quite right that the
smallest microblocks would produce a full-sized water_source node when melted.
So I toned them down a bit by changing their melt to a temporary,
2-second water_source. See "melts" in abms.lua file for the various intensities.
___...::: ATTENTION MINETEST SERVER OPERATORS :::...___
You may or may not have noticed in your server logs that MoreBlocks stairs/slabs/
panels/microblocks are not recorded as to when, who, what, and where. This is
important information when trying to determine if a player who dug these blocks
is the owner (the player who placed the block) or is a griefer stealing the block.
There is an option that will log when these blocks are placed but it comes at the
cost of losing the auto-rotation of those blocks when placed. They can still be
rotated with a screwdriver but if screwdrivers are disabled on your server your
players won't be able to position MoreBlocks, saw-made blocks.
To enable logging the placement of these blocks, un-comment these lines:
--on_place = minetest.item_place
