Place one block inside another

[Kevin Krüger]

Hi guys

I would like to place a metal rod inside a Stone Slab. The Stone Slab has a hole in the middle so that the rod fits in, how do I do this with the possibilities of Forge?

Kind regards

could you elaborate? is the stone slab the vanilla slab, or a block of your own? what do you mean by "inside"? is the rod a block?

Good Morning kiou.23 

The slab is our own slab, also it is an block. The Rod is also an Block.

And what I mean with "inside" is, our own slab has in the middle of the block an square hole.

you can't have two blocks occupy the same space. however, you could it a property in the slab's blockstate, and use of the blockstate json file to point to different models. then handle the logic on the onBlockActivated, to switch the blockstates

Look at the SlabBlock to see how it handles becoming a double slab.
