I would like for someone to make me a plugin that can disable editing (moving items) in your own inventory. Or disable opening the inventory itself. Thank you
I might be able to do this, as it sounds like a pretty simple plugin. However, disabling opening the inventory itself is client - side, and so server plugins can't do it without a client mod, which Bukkit does not support.
Spam the client with Packet101CloseWindow() to stop the opening of anything. The best way to accomplish this would be as you suggested, to cancel all the click events.
