Client sided optifine like CIT implementation

[FloweyTF 0]

Background:
I am writing a mod for all things hypixel. When it come down to hypixel skyblock, it adds a large number of custom weapons and such.

Anyways, the main question is: How do I write a client-sided mod that changes the texture of an item given its name?

Item textures are controlled my models, which are controlled by resource packs (mods are also resource packs).

If you really just want to change the texture, there is no reason to make a mod, you can just make a resource pack. If you need custom model rendering, you need a custom model loader as well.

No, its not the only reason for this mod, its just a feature. Is there any way I can code it so that it works like this?

I already told you what you need to do. Have you tried anything?

I dont really know what to do

Put whatever models / textures you want to override with your mod in src/main/resources and then the same path they have in vanilla Minecraft.

Tada, you have changed a vanilla texture with your mod.

Well, I know that much. However, it doesn't allow the item texture to be changed dynamically based off of the item name

You need a custom model loader which changes the model based on the item name then.

Do you have some example code that I could look at?

Forge has a "separate-perspective" model, which allows you to embed several models based on perspective: https://github.com/MinecraftForge/MinecraftForge/blob/1.16.x/src/main/java/net/minecraftforge/client/model/SeparatePerspectiveModel.java. You can do something similar but allow embedding models based on item name.

does it have to implement IModelGeometry?

[diesieben07 7614]

Yes, IModelGeometry is the forge version of an "unbaked" model, i.e. just the model data loaded into memory. This will then be baked into a BakedModel, which is basically just a list of quads to be uploaded to the GPU.
