How would I go with calling a function when changing inventory items

Ok, so the problem is the following...

I'm trying to make some kind of "invsee" plugin and I want to refresh the inventory every time the inventory has changed.

All I've tried 'till this point is InventoryClickEvent and InventoryInteractionEvent.

That's where I have a problem. InventoryClickEvent only updates after the player click again after moving the item for me to refresh it.

For example, when a player picks up an item, I don't see it gone, unless he places it back down. When he does, I don't see it until he picks up another item, which I don't see it disappear unless he places it back down. ETC!

I want it to be "realtime" and I don't want to use Scheduler, because I've already tried that, but when I do that, screen flashes.

Thanks for the help, if you need parts of code or something just say.

Solution

Unless you intend to perform more complex actions other than looking at and possibly manipulating a player's inventory you can simplify this task. Given two Player objects admin and target, where admin needs to look at target's inventory, you can view the inventory as follows:

Player admin = ...
Player target = ...
admin.openInventory( target.getInventory() );

This will allow you to view, add, remove, or change items in target's inventory.
