[Solved] Blockstates and item model for TileEntity

[Jay Avery]

I have a block which is rendered as ENTITYBLOCK_ANIMATED like a chest. The block is rendering in the world as expected, but there are two problems:

1. [Solved with custom IStateMapper] I get this console error, because it's looking for a blockstates json, even though it doesn't need one because it doesn't need a block model at all.

2. [Solved, I was just forgetting to register the item model at all] The itemblock is rendering with the missing model texture in the inventory, even though I have an item model json (and there's no corresponding console error). My item model is at models/item/block_box.json:

Spoiler

{
    "parent": "item/generated",
    "textures": {
        "layer0": "jjmod:items/box"
    }
}

You can fix this by registering an IStateMapper that returns an empty Map.

I'm not too sure about this.

Thanks - do you know of a tutorial or example for using IStateMapper?

 

Edit: nevermind, I figured it out! This has removed the console error of problem #1, but the item is still not working.

 

Edit again: turns out I had just made a mistake and wasn't registering the item model at all, so that's fixed #2, oop.

It's an interface with a single method, implement it to return Collections#emptyMap. There's no need for a tutorial or example.

 

Register it by calling ModelLoader#setCustomStateMapper on the client side in ModelRegistryEvent (if you're registering your Blocks/Items in RegistryEvent.Register) or preInit (if you're registering them in preInit).
