I've been looking through the EntityItemFrame class to try to get a clue as to how MC displays an item that's stored in the frame.

I have a Shelf block that acts as a container for four item stacks and I'd like to display a single item that represents each stack on the shelf at a specific location in the cube.  I can't seem to find which methods are used to actually display the item in Item Frames, and I'm not even sure I can use the same method.

 

Does anyone know how to do this like Item Frames do, or a better way?

 

Here's my shelf title entity:

Hi

 

Have you looked in the RenderItemFrame.doRender()?  The item rendering is called from here.

 

-TGG

 

Ah!  no, I hadn't found that one.  I had only found EntityItemFrame, but this RenderItemFrame class is what I was looking for.  I'll go study it and find out if I can use some of it for what I want.  Thanks!
