I would like to set a zombie's target and make it attack something. Specifically, I noticed that when a wolf attacks a zombie, the zombie doesn't attack back (PigZombies do though). I would like to make it defend itself when a wolf attacks it. Preferably, I would like to do something when an EntityDamageByEntityEvent is called. I know setTarget doesn't work, but in this case setGoalTarget also doesn't work. I do NOT want to create a custom entity for this situation, but I am okay with using NMS and reflection. Anybody have any idea?
