Has something changed about how container items work? Before updating to 1.10.2, I used to have it working so certain tools could be used in the crafting grid and would remain there but take damage after crafting the item. Now my tools stay in the crafting grid but they get a red zero overlaid over them and disappear as soon as they are clicked on. I'm pretty sure I didn't change anything about that part of the code during the update.

 

@Override
public boolean hasContainerItem(ItemStack stack)
{
 return true;
}

@Override
public ItemStack getContainerItem(ItemStack stack)
{
 stack.attemptDamageItem(1, PrimalToolAxe.itemRand);
 return stack;
}

Seems like you need to return a new ItemStack now instead of just the original itemstack just damaged.

Indeed, you're right. Many thanks.

 

How did you know? I keep thinking I should be able to figure these things out on my own, but I guess I don't know where to look.

The red 0 means sttacksize 0. Which means that the stack's size is being decreased, so if you create a new ItemStack instance its size will not be decreased, you could also increment the size by one if you wanted to.
