Hello there!
I have a problem adding slabs. I've made them: they have texture, no lighting bug etc. But they cannot stack on each other, and to fix this I have to do (this works for 1.6.4):
Item.itemsList[mySlabId] = new ItemSlab(mySlabId - 256, (BlockSlab)halfSlab, (BlockSlab)doubleSlab, false)
However, this code isn't working for minecraft 1.7.2. I have tried
Item.itemRegistry.addObject(Block.getIdFromBlock(mySlab), mySlab.getUnlocalizedName(), new ItemSlab(halfSlab, (BlockSlab)halfSlab, (BlockSlab)doubleSlab, false));
but it doesn't work. Please help me.
Best regards,
Mateiaru
