check dmobs... i wouldnt call them the "most" basic
OK I was exaggerating with "most" but Mobs Redo is very limiting. How do I have a mob shoot and walk at the same time? Why does it keep playing the walking animation when a mob is standing and shooting? How can I have more than one sound for a particular perpose? These are rhetorical questions not honest questions.
Mobs can be as basic or as complicated as the user wants them to be by using the api functions or adding their own custom one's.
Yes, anything is possible if you start modifying Mobs Redo but do to the nature of Mobs Redo it is hard to modify without breaking other things.
Mobs Redo isn't all bad. You can get functional mobs up and going with little effort. Something most other mob APIs can't say.
