Hello, i'm trying to create a simil stone cutter block. I have done 99% of the mod, create a block, a tilentity, container and a screen. The tileentity has 9 slots (which 6 are input and 3 are for output). The screen shows some recipes that the player can craft, putting specific items in the input slots. When the player clicks on a item that he can craft, the item is added but only on client, so when an update block is sent, everything is removed from the "inventory" (it is not even registered on server side) It's 4 days that i'm trying to understand how to do this... I appreciate only a guide (maybe a commented guide) to solve this. Here are my classes: The Block: The Tile Entity: The Screen: The Container: Here's how the gui (screen) works: every tip is very appreciated
