[1.8] How to render an item in a block, like the item frame only shelves?

RoseCotton · March 2, 2015

Hi, All.

I'm studying up on the stairs block model because I want to edit it into two-tier shelves on which items can be stored and displayed.

Does anyone know how to add an item into a block so that it is rendered in a specific position?

You will need a tile entity for your block that has an inventory. Then you'd render each inventory element in the appropriate place based off its index.

Thank you, Draco18s.

Can anyone point me toward an example of a title entity? The chest and the item frame are the closest I can guess, but the code is obfuscated and really, really difficult for a beginner modder to read. Do you know if there are any good tutorials? Or examples someone has been kind enough to share (and hopefully comment...)?

Thanks!

I'd ignored that tutorial because I thought it was only applicable to pre-1.8 due to the x,y,z format of the position data. I'll check it out.

Its not completely irrelevant.

Hi

This example project has working examples of a TileEntity, a container, and a TileEntitySpecialRenderer, all of which might be useful in this case.

https://github.com/TheGreyGhost/MinecraftByExample

This tutorial site has a couple of entries on TileEntities and containers too, for background info.

Also, here's how I rendered a container item.

https://github.com/Draco18s/Artifacts/blob/master/main/java/com/draco18s/artifacts/client/ModelPedestal.java#L60-80

It only does one item (intended to be rotated flat against a top surface) but it should give you an idea of the necessary parts.

Thank you very much, Grey Ghost, for minecraftbyexample! finally, some comments!

I was looking through the mbe30_inventory_basic java file to see what I can adopt for my ShelfBlock title entity and following some event handler tutorials and put together the files ShelfTitleEntity.java and ShelvesEventHandler.java, only to find that now when I place my shelves block (whose item looks like my shelves) it comes out as a chest! I thought I had understood each code addition enough (due to the well-named methods and much-appreciated comments) that I would have noticed if I suddenly switched the block model to the one for a chest.

What key words can I look for to indicate where in the files I might have switched the model from shelfBlock to chest?

RoseCotton · March 5, 2015

Ok, this is hilarious; the sun finally came up in my test game and now I see that when I place my BlockShelf, it actually renders a chest embedded in my shelves.

I found that the I'd changed the BlockShelf class to extend BlockContainer, not just Block, and that BlockContainer has a getRenderType() method that returns -1 instead of 3 like Block's getRenderType() method. So I overrode getRenderType() in BlockShelf to return 3, but that didn't seem to help.

UPDATE:

I fixed it.

I had:

   public TileEntity createNewTileEntity(World worldIn, int meta)
    {
        return new TitleEntityChest();
    }

instead of:

   public TileEntity createNewTileEntity(World worldIn, int meta)
    {
        return new ShelfTitleEntity();
    }
