Mobs have Custom Names. Mineplex has the ability to set the custom names to a certain player. What do I mean? I mean certain players see the mobs with different names... For example, someone hasn't bought the machine gun kit for mineplex on Super Paintball. They would see the cost next to the zombie kit's name. Only people who haven't bought the kit see the price. People who have bought it, only sees the Kit name. How is this done?
