ItemBlock with IItemRenderer

[Letiu]

Hi everyone,

 

I have the following problem I want to render a block in the inventory based on nbt. Sadly this is not possible with ISimpleBlockRenderingHandler (as far as I know).

Since I was going to add an ItemBlock anyway I tried using an IItemRenderer on it. For a normal Item the renderer was working fine but not with the ItemBlock. After some tracking I figured that MinecraftForgeClient.getItemRenderer(item, INVENTORY) didn't return the renderer.

 

public static IItemRenderer getItemRenderer(ItemStack item, ItemRenderType type)
    {
        IItemRenderer renderer = customItemRenderers[item.itemID];
        if (renderer != null && renderer.handleRenderType(item, type))
        {
            return customItemRenderers[item.itemID];
        }
        return null;
    }

 

The method uses the itemID from the stack which should be the blockID. If I remember correctly ItemBlocks have their own or shifted ids.

 

Is there a proper way to register IItemRenderers for ItemBlocks or was it never intended to? (I'm testing this on 1.7.2 atm)

The only work around I found so far was to create an Item with its own normal id.

 

hopefully someone can help me out here.

Register it like any other item renderer. For the item, use Item.getItemFromBlock(block)

Thanks for the help. I actually made a mistake in my ItemBlock class and looked everywhere else q.q

There's also "cheaty" ways of doing what you need.  If you're just trying to render an item, you can do this:

 

RenderManager.instance.renderEntityWithPosYaw(es.itemEnt, 0, 0, 0, 0, 0);

 

'es' is the TileEntity being rendered (this line is in my TileEntitySpecialRenderer and Model class structure) and the TE holds a reference to an item entity object (the object you get when you drop items on the ground, but this one is not added to the world) and then I just tell the renderer to render it (and have some GL11 calls to position and rotate it where I'd like it to render).
