Naw, I'm already doing a pick nearest which works ok, thanks though psycholize! Problem is since this is a platformer, when I deflect a projectile it will go to the nearest enemy, but that enemy could be above/below the player through a hard tile.
I'm trying to get it so that maybe an array will store the enemies that are within distance, and Line of sight, so when a projectile is deflected it will choose random one of those players to go towards.
