Hi. I am trying to create a menu that the player can interact with. I would like the menu to be in the form of a chest inventory. After the chest inventory opens to the player, the player can click on an ItemStack in the inventory, which would then carry out an action. How would I create a chest inventory and force the player to open it (it should be done without actually creating a chest in the world)? How do I detect when the player clicks on an item, and perform certain actions?
