[SOLVED] Snow biomes

[pampogokiraly]

Hello!
I personally don't like the snow-pine biome (and also the normal snow biome but i need that because i like to get some snow and ice) and i want to remove it completely from the v7 mapgen, and i don't know how to do that.
Can someone help me out with this please?

Go to your minetest directory and then open games/minetest_game/mods/default/mapgen.lua in your code editor of choice.

To find the biome definitions of the taiga, search for '-- Taiga' with ctrl+F. You can then comment out the biome definition blocks of the taiga biomes by surrounding them with --[[ <code> ]]

Before:

Code: Select all

minetest.register_biome({
		name = "tundra_under",
		node_cave_liquid = {"default:water_source", "default:lava_source"},
		node_dungeon = "default:cobble",
		node_dungeon_alt = "default:mossycobble",
		node_dungeon_stair = "stairs:stair_cobble",
		y_max = -256,
		y_min = -31000,
		heat_point = 0,
		humidity_point = 40,
	})

	-- Taiga

	minetest.register_biome({
		name = "taiga",
		node_dust = "default:snow",
		node_top = "default:dirt_with_snow",
		depth_top = 1,
		node_filler = "default:dirt",
		depth_filler = 3,
		node_riverbed = "default:sand",
		depth_riverbed = 2,
		node_dungeon = "default:cobble",
		node_dungeon_alt = "default:mossycobble",
		node_dungeon_stair = "stairs:stair_cobble",
		y_max = 31000,
		y_min = 4,
		heat_point = 25,
		humidity_point = 70,
	})

	minetest.register_biome({
		name = "taiga_ocean",
		node_dust = "default:snow",
		node_top = "default:sand",
		depth_top = 1,
		node_filler = "default:sand",
		depth_filler = 3,
		node_riverbed = "default:sand",
		depth_riverbed = 2,
		node_cave_liquid = "default:water_source",
		node_dungeon = "default:cobble",
		node_dungeon_alt = "default:mossycobble",
		node_dungeon_stair = "stairs:stair_cobble",
		vertical_blend = 1,
		y_max = 3,
		y_min = -255,
		heat_point = 25,
		humidity_point = 70,
	})

	minetest.register_biome({
		name = "taiga_under",
		node_cave_liquid = {"default:water_source", "default:lava_source"},
		node_dungeon = "default:cobble",
		node_dungeon_alt = "default:mossycobble",
		node_dungeon_stair = "stairs:stair_cobble",
		y_max = -256,
		y_min = -31000,
		heat_point = 25,
		humidity_point = 70,
	})

	-- Snowy grassland

	minetest.register_biome({
		name = "snowy_grassland",
		node_dust = "default:snow",
		node_top = "default:dirt_with_snow",
		depth_top = 1,
		node_filler = "default:dirt",
		depth_filler = 1,
		node_riverbed = "default:sand",
		depth_riverbed = 2,
		node_dungeon = "default:cobble",
		node_dungeon_alt = "default:mossycobble",
		node_dungeon_stair = "stairs:stair_cobble",
		y_max = 31000,
		y_min = 4,
		heat_point = 20,
		humidity_point = 35,
	})

After:

Code: Select all

minetest.register_biome({
		name = "tundra_under",
		node_cave_liquid = {"default:water_source", "default:lava_source"},
		node_dungeon = "default:cobble",

		node_dungeon_stair = "stairs:stair_cobble",
		y_max = -256,
		y_min = -31000,
		heat_point = 0,
		humidity_point = 40,
	})

	-- Taiga
--[[

		name = "taiga",

		depth_filler = 3,
		node_riverbed = "default:sand",
		depth_riverbed = 2,
		node_dungeon = "default:cobble",
		node_dungeon_alt = "default:mossycobble",
		node_dungeon_stair = "stairs:stair_cobble",
		y_max = 31000,
		y_min = 4,

		humidity_point = 70,
	})

	minetest.register_biome({

		node_dust = "default:snow",
		node_top = "default:sand",
		depth_top = 1,
		node_filler = "default:sand",
		depth_filler = 3,
		node_riverbed = "default:sand",
		depth_riverbed = 2,
		node_cave_liquid = "default:water_source",

This forum has an every day surprise for everyone of us :)

Instead of messing around in minetest biomes, just write a small mod to reregister the biome to your needs:

Code: Select all

if minetest.registered_biomes["rainforest"] then
	
	local rainforest = minetest.registered_biomes["rainforest"]
	rainforest.node_river_water = "water_life:muddy_river_water_source"
	rainforest.node_riverbed = "default:dirt"
	rainforest.depth_riverbed = 2
	rainforest.node_water_top = "water_life:muddy_river_water_source"
	rainforest.depth_water_top = 10
	minetest.unregister_biome("rainforest")
	minetest.register_biome(rainforest)
end

This is just an example from my water_life mod. You can do this with any biome you like.
Just see lua_api in your minetest doc folder.
