I've been looking for a plugin where you can control whether a mob is passive during the day and things of that nature. Don't say Mob Control, don't say "search". Done and done.
I've been hoping for Mob Control to be updated - the only other 2 I've come across are : CrowdControl (which has been updated to #602 and bmobs which hasn't. Crowdcontrol is the nearer of the 2 that might do what you want ...... if you come across anything else, please let me know ........
Sadly, not what I'm loooking for. I meant changing a mobs...style, per se. Like, if I wanted to make Pigzombies Aggressive and not Passive, then I would edit it in a .yml or something.
