MCItemStackMutable

Link to mcitemstackmutable

An MCItemStackMutable object is the same as any other IItemStack. The only difference is that changes made to it will not create a new ItemStack, but instead modify the stack given.

This is useful for example when you are dealing with Event Handlers and need to shrink the stack the player is using without assigning a new stack.

Importing the class

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.
