What I meant by inventory data, is I want to get all the items in the inventory. I need this information to test if the inventory being opened is actually a bank, because the bank inventory always has the same item in the top right corner

Client. Also, how can I check if they have clicked in said inventory after getting the inventory data? So basically the server I play on cancels the chest open event with a plugin, and opens a different inventory called Bank. How can I test for the bank being opened?

First off, how would I check if a player has a chest open?

How would I be able to add clickable icons (similar to JEI) when in an inventory that has a specific name? I want to create buttons that only appear when inside said inventory. Also why are the forge docs not great? Is there anywhere that has a list of every function / method / event?
