I currently have a custom hopper which uses the exact same code as the vanilla hopper (accomplished by having BlockAdvancedHopper extend BlockHopper and TileEntityAdvancedHopper extend TileEntityHopper), but it is going gain additional functionality down the road. How do I make it  so the custom hopper uses the same models and textures as the vanilla hopper? I have not been able to find anything on the subject, which is why I'm asking here. I'm using version 1.9.4 Forge. The block works just fine, the problem is just the model and texture.

You can probably have it extend the vanilla hopper class, overriding methods as needed. If not, copy its code.

I've tried both extending the class and copying the code but neither change the model or texture of the block.

The hopper uses the same baked model system as regular blocks, you can change your block's model and textures from its blockstates file.

Try providing the location of hopper model through ModelLoader.setCustomModelResourceLocation(...),

and bind hopper state mapper using

ModelLoader.setCustomStateMapper((Your Block), (new StateMap.Builder()).ignore(new IProperty[] {BlockHopper.ENABLED}).build());

(Gotten from BlockModelShapes#registerAllBlocks)

 

This will ensure that the model will be identical to the vanilla hopper model in any case.

 

If you want to make your model modifiable in resourcepacks, you should copy the model, textures, and blockstates file for the hopper.

 

EDIT: first parameter of setCustomStateMapper should be your block, sorry for the previous mistake.

How would I go about implementing ModelLoader#setCustomResourceLocation?

 

I tried

        ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(MyMod.instance.hopper), 0, new ModelResourceLocation("block/hopper"));

but it threw a NullPointerException.

Ok, I have sorted out most of the problems, I just need to figure out how to correctly reference and assign the model names. Here is the current code:

   ModelLoader.setCustomModelResourceLocation(TestMod.instance.hopperItemBlock, 0, new ModelResourceLocation("models/block/hopper_down"));
        ModelLoader.setCustomModelResourceLocation(TestMod.instance.hopperItemBlock, 0, new ModelResourceLocation("models/block/hopper_side"));
        ModelLoader.setCustomStateMapper(TestMod.instance.hopper, (new StateMap.Builder()).ignore(new IProperty[]{BlockHopper.ENABLED}).build());
    

How do I make it  so the custom hopper uses the same models and textures as the vanilla hopper?

This amuses me.  I read this as "I want to use the same textures, but when I tried that, it used the same textures (achieving the effect I want): Something is wrong."
