Sorry if I'm asking a dumb question or anything, but how do you add a maximum durability to a item?

I want to make an Item which takes damege every time you craft somethinng with it, I've already added the recipe where the Item takes damage, which looks like so:

 

GameRegistry.addRecipe(new ItemStack(Item.coal, 4),
		 new Object[] {"i","c",
	 Character.valueOf('c'), Item.ingotIron,
	 Character.valueOf('i'), new ItemStack(crusher, 1, -1)
 });

 

And I've added this:

@Override
 public ItemStack getContainerItemStack(ItemStack itemStack) {

	 itemStack.setItemDamage(itemStack.getItemDamage() + 1);

	 return itemStack;

to the Item file.

 

So, can anyone help me?

RedPower has that and its easy to copy from her surces.

Read the redpower 2 Source. Equilant exchange uses containerItems. But redpower remove the item and rebuild it with one more damage
