I am currently making a map and I managed to spawn in a ginormous Groudon into my world. I would like this to be obtainable to other players, but when I go a certain distance from it, it despawns. I've tried name tags to rectify this, as in vanilla name tags prevent mobs from despawning, but that doesn't seem to work either. I thought using Pixelmon Spawners would work, but it seems sizes cannot be specified and are randomly generated.
So is there any way to spawn a Pixelmon into the game and prevent it from spawning if the player leaves the game or goes a certain distance away from it?
Any help would be greatly appreciated! Thanks. :)
