[1.10.2] What is the Entity AI where it would attack all of HOSTILE mobs but doesn't harm friendly ones?

The title describes all.

You will need to add an entity AI to attack the current target, and one to target the nearest hostile mob. Have a look at EntityWolf#initEntityAI for a good example of how that works.

 

As far as I can see, though, vanilla doesn't have an entity AI for targetting the nearest hostile mob, so you will need to create it yourself. EntityAINearestAttackableTarget is close, but only accepts one type of targetable Entity.

 

You can tell if a given type of Entity is hostile because it will implement the IMob interface.
