It's very efficient and does most of its work on separete threads. You will not notice any pull from it.
I did a plugin exactly like this, http://dev.bukkit.org/server-mods/killreward/ . I could change it if you miss anything...
hey, can you add that you can set the amount that wil be taken and the amount that wil be given? that would be nice
What should you get for it? When it's a Diamond an Item or Money it's a 3 Line Java Code (only the KillListener)
Ok is the Money Plugin iConomy or what is the Plugin and how much money should the Person get? And only for Killing a Player or for Mobs too?
