[Solved] [1.8] Dynamic Item Texture (Custom TextureAtlasSprite)

[MrIbby]

Right now I'm trying to figure out how to make a custom compass for 1.8 and I'm wondering if anyone on the Forge Forums has already made one. Why spend time reinventing the wheel when you can make something cool?

 

SOLUTION:

It's actually very easy to override a texture with your own TextureAtlasSprite. This is the code I used:

@SubscribeEvent
public void onPreTextureStich(TextureStitchEvent.Pre event) {
    Map<String, TextureAtlasSprite> mapRegisteredSprites = ReflectionHelper.getPrivateValue(TextureMap.class, event.map, "mapRegisteredSprites", "field_110574_e");
    mapRegisteredSprites.put("mymod:items/my_item", mySprite);
}

Basically I need some way to dynamically update the texture.

The important thing is what kind of data does it use.

 

Anyway, the class you want to extend is TextureAtlasSprite

I've already got the BlockPos and TextureAtlasSprite sorted out, but I can't figure out how to override the default texture. To provide some background info, I'm updating the code from 1.7.10 to 1.8, so most of the complicated stuff is already done (except for the item texture).

In your icon registration method, tell it to register the custom sprite.

 

Edit:

I've lost track of where I did it that way. But the IIconRegister interface is only used by one class, so figure out what that class is, cast to it, and add the atlas sprite to it manually.

IIconRegister doesn't exist in 1.8?

Looking at the vanilla compass rendering code, it looks like most of your current code should still work with a few minor changes. Just use the

TextureAtlasSprite

's

ResourceLocation

as the texture of your item model.

 

You'll want to look at

RenderItemFrame#renderItem

to see how the vanilla compass is rendered in item frames and use it as the basis of your

RenderItemInFrameEvent

handler.

Derp. Been mobile all day, didn't notice.
