In the ItemBlock's onItemUse(), I mean

Yeah, but what I thought I'd do is like: w.setBlock(x, y, z, machineBlock); w.setTileEntity(x, y, z, MachineRegistry.getMachineClass(itemStack.getStackDamage()).newInstance());

And does it correspond to the created block's metadata, or the used ItemStack's damage? Also, can I work around this method completely? I'd rather have my ItemBlock class do the work.
