Hello, I hope this is not a repost, I only found a subject about it (and sorry for my bad english)
I’m looking to change the aggro range from entities (spider/zombies), I found nothing so I tried to use the “setTarget” option on agents but it only worked for skeletons that started to fire far away but didn’t moved.
I found a post from Cleardragon, where there seems to be a solution :
I’m a bit new to this and I don’t understand how to, even with the explications from Aaron1011 
Is there another way ? Or can someone explain me this in a bit more details ? 
Thanks !
