Sorry, I looked around and couldn't figure out how to do that, do you know of any good place where it can tell me how to?

December 10, 2019

I'm trying to add a custom 5 by 5 crafting table into my forge 1.12.2 mod. I want so that when a button in the gui is pressed (The craft button) it crafts an item, this is run through the craftitem() function in the tile entity class. The problem however is that when I try to craft in game, is shows up the correct item but when I try to click it to take it out (or update the container in some way), everything resets to how it was before I pressed the craft button.

Can anyone see anything wrong or missing from my code that would cause this problem?
