Do you need this to find out if a stack has been splitted "inside" the inventory/chest (i.e. the new stack still remains in the inventory/chest), or is it just relevant when moving the new stack from the inventory to a chest (or vice versa)?
Good morning Red, It relevant for when moving and splitting a new stack from inventory to chest as well as chest to inventory.
So the following methods
What is happening is it is creating illegal states (amongst other things). You will actually get kicked from the server with a "you are using modified files" warning.
When you drag a stack from inventory to chest and try to stack an existing item in the chest (with right click) you also get a a graphic glitch
I am using:
to detect the exchanged stack size, but when a stack is split with right click I have no means to detect that this has happened. I.e. the exchange is actually 1 instead of say 64
