[1.12] Creating Textures for an item in game

[BeardlessBrady]

Hey, Im more so looking for a way to create the texture and put it on an item on the fly.

 

Hopefully someone can help, Thanks

Do you mean dynamically generating textures? Or are you changing the texture based on data in the item?

I want players to be able to create the item texture in game. So Dynamically generating textures.

I don't think that's possible

It might be, but it isn't easy.

The fact that it's item textures complicates things a lot. 

First you would need to work with a BufferedImage to have the image that is later converted into a sprite. Presumably you would serialize them into a folder of sorts on the user's hard drive. The problem here is that you also need them to exist on the server if you want other players to see the texture.

Once the user has done the image in-game you would send it to the server, and the server would then send it to all other players.

The image recieved would be stored on the user's hard drive. Then you trigger a resources reload.

You would need to store a TextureAtlasSprite per image somewhere. You can create TextureAtlasSprite objects using TextureMap#registerSprite. Alternatively you might just instantinate one and use TextureMap#setTextureEntry to add it to the map. You need to do this in the TextureStitchEvent.Pre.

Then you would either need a custom IResourcePack associated with your mod to load the images from the folder or you can use custom TextureAtlasSprite implementations that override TextureAtlasSprite#hasCustomLoader and TextureAtlasSprite#load.

Finally you would need a custom IBakedModel for your item that returns a custom list of quads with your custom texture - you can use BakedQuadRetextured to easily change the textures on existing BakedQuads.

The hard part here is making sure all clients are aware of the new textures. Also the fact that the resources need to be reloaded every time the user joins a server or every time a new texture is generated will upset people since reloading resources takes a while, especially on big modpacks.
