stackSize is private - how would I modify the stacksize now? [Forge 1.11.2]

Hi. I am very new to Minecraft modding (and by extension, this is one of my first ventures into Java). Sorry if this is the dumbest question ever asked!

 

I'm trying to decrease the stack size of any Iron Ingot in the player's inventory by 1, as long as they're right clicking my custom item.

However, the problem arises because I can't find a way to modify the stack size. I can see that in ItemStack.java, the stackSize variable is private. Can't modify it in my item code.

 

Here is the code that I'm trying to get working.

 

Is there an alternative way I can use to decrease my stack size? Can't figure it out.

I'm using Forge 13.20.0.2228, for 1.11.2. Thanks!

You can use getCount() to get stack size or setCount() to set stackSize. The stackSize is private because ItemStack in forge 1.11.2 is never null. You should use ItemStack.EMPTY instead of null!

Thank you so much! It works perfectly.
