When defining custom entity AI (MC 1.12.2), using the Attack AI and choosing to attack "EntityMob" I have two issues:
1) The entity will attack others of its kind, which is pretty annoying. Some kind of "do not attack" dropdown is needed in this too, so we can blacklist some other mobs it is not going to attack (including itself).
2) The entity doesn't seem to attack ALL mobs from other mods. It only attacks some of them. Eg. it will attack the Anu boss from Fossils and Archeology, but will not attack Dinosaurs from that mod. It won't touch vanilla cows, but will attack vanilla zombies. Is the definition of a "mob" wrong? It seems to only involve hostile ones. How can we get it to attack passive mobs too? At the moment, I have also told it to attack animals and ageables, as a compromise. Or is that deliberate?
