Hi, this is my first post and I've just started out with modding with Forge. I'd like to know if there is any way to register when a player has right-clicked on another player on a SMP server? I've come across the "onBlockActivated()" method but I couldn't find anything similar when browsing Entity classes. If possible, I'd like to send out some packets once a player shift+right clicks an other player. Is it possible and if so, how? Thanks!
