Minecraft to Minetest texture converter

by anatole » Post

Hi! I wrote a Ruby script that converts textures from Minecraft to Minetest. Here it is:

Code: Select all

#!/usr/bin/env ruby

require 'RMagick'
require 'zip/zipfilesystem'

def image_from_archive archive, image_name
    blob = archive.file.read(image_name)
    terrain = Magick::ImageList.new
    terrain.from_blob(blob)
end


def cut image, size, table
    table.each do |current|
        x = size * current[0]
        y = size * current[1]
        tile = image.crop(x, y, size, size, true)
        tile.write current[2]
    end
end

def fix_greens
    files = ["grass.png", "grass_side.png"]
    files.each do |current|
        img = Magick::ImageList.new(current)
        img = img.colorize(0.6, 0.6, 0.6, "#003F00")
        img.write(current)
    end
    img = Magick::ImageList.new("leaves.png")
    img = img.colorize(0.8, 0.8, 0.8, "#003F00")
    img.write("leaves.png")
end

def generate_rails size
    straight = Magick::ImageList.new("rail.png")
    curved = Magick::ImageList.new("rail_curved.png")

    tile = straight.composite(curved, 0, 0, Magick::OverCompositeOp)
    tile.write("rail_t_junction.png")

    horizontal = straight.rotate(90)
    tile = straight.composite(horizontal, 0, 0, Magick::OverCompositeOp)
    tile.write("rail_crossing.png")
end

def extract_crack terrain
    size = terrain.rows / 16
    nstages = 5
    crack = Magick::Image.new(size, size * nstages) {
        self.background_color = "#00000000"
    }
    selected_stages = [2, 3, 5, 6, 9]
    nstages.times do |stage_number|
        x = selected_stages[stage_number] * size
        y = 15 * size
        tile = terrain.crop(x, y, size, size, true)

        x = 0
        y = stage_number * size
        crack.composite!(tile, x, y, Magick::CopyCompositeOp)
    end
    crack.write("crack.png")
end

terrain_table = [

Zip::ZipFile.open(ARGV[0]) do |pack|
    Dir.chdir ARGV[1] if ARGV[1]
    terrain = image_from_archive(pack, "terrain.png")
    size = terrain.rows / 16
    cut(terrain, size, terrain_table)
    extract_crack(terrain)
    fix_greens
    generate_rails(size)

    items = image_from_archive(pack, "gui/items.png")
    cut(items, items.rows / 16, items_table)

    icons = image_from_archive(pack, "gui/icons.png")
    scale = icons.rows / 256
    tile = icons.crop(scale * (16 + 4*9), 0, scale * 9, scale * 9, true)
    tile.write("heart.png")
end

You should install RMagick and rubyzip to use it.

It must work with any texturepack, howerer there are some problems with transparency.

Here is a list of what does not work:
  • I don't know how to properly colorize the grass and leaves
  • With the default texturepack (minecraft.jar) cracking texture (crack.png) makes the block completely transparent but with other texturepacks it works right
  • To make crossing rails texture i combined two others and it looks ugly
  • Fences and signes don't convert

sounds like the texture transformer thats used in manic digger and i don't believe that you need to contact the owner if your not distributing the texture pack but i could be wrong otherwise great job :)

Yes, this script just cuts a large source texturepack into many small files used by Minetest and all copyrights belong to authors of this texturepack.

I just converted a pack by hand a few weeks ago... :(
Still nice.

I know this is out-of-date, but maybe it can help ease the tension in transferring a whole pack.

I changed the texture names
So.. how to use this? I've been attempting to use this for a couple hours now and get nowhere.

When trying to run it I get:
"./convert.rb:4:in `require': no such file to load -- zip/zipfilesystem (LoadError)
from ./convert.rb:4"
I can't seem to find any way to "fix" this (not used to Ruby). Running on an Ubuntu based distro.

neither am I i just changed the texture names for most recent version it appears that it divides the file into sections and names them accordingly

I've made a couple of small additions to this script, namely it will know always output the colorized leaves as "default_leaves.png" instead of just "leaves.png" and it will create a "default_dirt.png" which it wasn't before. It would be really great if someone who is better at Ruby then I am could modify this script to extract wool, bucket, and stonebrick textures from a Minecraft texture pack so it would be easy to use generated textures with mods too.

Code: Select all

#!/bin/env ruby
require 'rubygems'
require 'RMagick'
require 'zip/zipfilesystem'

def image_from_archive archive, image_name
    blob = archive.file.read(image_name)
    terrain = Magick::ImageList.new
    terrain.from_blob(blob)
end


def cut image, size, table
    table.each do |current|
        x = size * current[0]
        y = size * current[1]
        tile = image.crop(x, y, size, size, true)
        tile.write current[2]
    end
end

def fix_greens
    files = ["default_grass.png", "default_grass_side.png"]
    files.each do |current|
        img = Magick::ImageList.new(current)
        img = img.colorize(0.6, 0.6, 0.6, "#003F00")
        img.write(current)
    end
    img = Magick::ImageList.new("default_leaves.png")

Okay, adding support for bucket and wool textures was a lot easier than I thought it would be once I realized this script split up terrain.png and items.png into grids. I've taken the liberty of throwing the script up on GitHub to make it easier to share and for other people to add to it.

If you have any ideas for additions or find any bugs please post here or on GitHub.

Just thought I would pop in to bump this since I've been working on the script again and updating it to make textures for some of the stuff that's been added to minetest since I lost interest in it a while ago. As usual, if you have any suggestions or are having a problem post here or open an issue on GitHub.
