Hello, I have been making this spawner stick that throws an egg, but I can't seem to find a way to make the stick have a different color on the texture based on what parameters are passed in. I have looked throughout all of the source of minecraft, and I couldn't find how spawn eggs are given different textures. And to clarify, I am trying to use a gray-scaled, two-layered model, and changing the color scheme of it, and by giving it a different parameter, I can get a different colored texture with the same look.

You'll need to create a class that implements IItemColor and register it with the ItemColors class, there's a getter for ItemColors in Minecraft(The class) . Do not ever reference your IItemColor server-side, IItemColor is client-side only so it does not exist in the server .jar.

 

Your

IItemColor#getColorFromItemstack

implementation receives a tint index argument telling it which part of the model is being coloured. This also applies to

IBlockColor

, which is used to colour blocks.

 

For regular models, the tint index is specified per face of each element.

 

For models that extend

builtin/generated

(or

item/generated

, which extends

builtin/generated

), the tint index is the texture's layer number (0 for the

layer0

texture).
