Using -1 will allow any Metadata to be used in the recipe, but it will probably not give you the correct wood blocks.... But you could add the recipes in a simple for loop. for(int i = 0; i <= 3; i++) { GameRegistry.addShapelessRecipe(new ItemStack(Block.planks, 3, i), new Object[] { new ItemStack(Block.woodSingleSlab, 1, i), new ItemStack(Block.woodSingleSlab, 1, i), new ItemStack(Block.woodSingleSlab, 1, i), new ItemStack(Block.woodSingleSlab, 1, i), new ItemStack(Block.woodSingleSlab, 1, i), new ItemStack(Block.woodSingleSlab, 1, i) }); } that should work.
