[SOLVED] Turn Slabs into Double Slabs

[Bedrock_Miner]

Hello everyone!

I have added a few slabs in my Mod, but if I place one Slab onto another they don't turn into a Double slab.. What do I have to add?

Which methods do I have to overwrite that it works?

I suggest you look unto BlockHalfSlab.

It goes into detail with the block bounds.

[Bedrock_Miner]

All the code I use is copied from Vanilla slabs. The Slabs are registered twice: one time for single- and one time for double slabs.

Anyone?

I solved it now on my own with the following Code:

 

@Override
public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ) {
	Block block = world.getBlock(x, y, z);
	if (block instanceof ModBlockSlab && !((ModBlockSlab)block).isDoubleSlab())
	{
		boolean brickBlock = false; boolean brickItem = false;
		if (((ModBlockSlab)block).isBrickSlab()) brickBlock = true;
		if (((ModBlockSlab)this.field_150939_a).isBrickSlab()) brickItem = true;

		int meta = world.getBlockMetadata(x, y, z) & 7;
		Main.logPlainText("brickBlock=" + brickBlock + "; brickItem=" + brickItem);
		if (brickBlock == brickItem && meta == stack.getItemDamage())
		{
			world.setBlock(x, y, z, brickBlock ? ModBlocks.DoubleBrickSlab : ModBlocks.DoubleSlab, meta, 3);
			--stack.stackSize;
			return true;
		}
	}

	return super.onItemUse(stack, player, world, x, y, z, side, hitX, hitY, hitZ);
}
