How would someone create a crafting GUI with the new GUI update?
I too wish to know sir!
You can make new inventory with GUI maker and add slots and then use events for crafting but the current implementation is buggy. We will try to improve this in the future.
So I did add slots to a basic GUI however I don't know what events to use cause I want to make a crafting table that can craft a 4x4 instead of a 3x3 item. However when I add the 16 slots I had an error in compilation.
