I'm currently porting Bukkit's iControlU plugin to Cuberite. This plugin allows a player to control another player's movement and inventory, and chat as the player.
The movement part of the plugin works just fine, but I'm having trouble with the inventory and chat. What I want to do is to send the inventory of the controller to the target whenever the inventories are different from each other, without causing a deadlock. The inventory is sent, but eventually (or sometimes immediately) the server stops responding. As for the chat, is there a way to chat as another player at the moment?
