ItemBlock with IItemRenderer

Recommended Posts

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.

greetings Letiu o/

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).

 

See line 57:

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
