[Idea] Texture map for tiles and items

[Hgdavidy]

Why dont add in the game support for large texture map like Minecraft, only 1 texture for all tiles for performance and speed making textures (all textures in one) (Ex: make a 512x512 .png with 1024 tiles support).
With this only need load one texture for all tiles = more performance and speed.

This is like sprite support...
For tiles and items.

Minetest combines all loaded Textures into one "Texture Atlas", which is simply a big Image

Oh nice

I dont have doubled the topic of miracle ...

the perfect idea is to create a enveloping imaging system (as used by most 3D games including MC)
how to apply will be Extremely simple:
could be done in two ways to suit the artist ...

1. texture atlas group by node
2. texture atlas group by multiple nodes

The image should be accompanied by a text file with the following form of texture mapping:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

default:chest (    -- name of node
    tile_set = {1,1, 48,32 },    --group of tiles => {px 1 horizontal, vertical, px 2 horizontal, vertical}
    tiles={
        {1,1, 16,16},    --top
        {1,17, 16,32},    --down
        {17,1, 32,16},    --side 1
        {17,17, 32,32},    --side 2
        {33,1, 48,16},    --front
        {33,17, 48,32},    --back
    },
)

benefits:
more organized
textures systems with a single 256-color indexed palette (lower file size, and lower system resources)
could be changed at will without changing all nodes in lua files

Yes, that would be nice, especially if it could be done for individual mods. The whole texture atlas of a game with several mods installed soon grows too large. As long as that doesn't exist: Does anybody know a way to split up Minecraft-like textures.png into individual files more or less automaticly? (preferably in lua)

[tonyka]

could be done a script for the program imagemagick ...
but I do not know how to do

[tonyka]

to be done with lua?
then with python ...
and is there any mod that can run python programs ...
for example this mod:

[Sokomine]

Lua was only a consideration because people running Minetest will have it. The mod might check if its image files are there and otherwise extract the texture.png. As far as I understand it the map mod does use an external python program to generate the map and reads only the generated image.

i like this idea too, it means a MC texture pack could be used without chopping any images, just write a few lines of code and its done. which means when the MC pack is updated, its super easy to update the MT version.

[tonyka]

yes, copy & paste...
