I need some help on my agem i need to make zombie ai.
It’s not as simple as you think, ai is hard
Ok but how do i do it?
The first question you have to ask is what you want your zombie to be able to do. Then, using the behaviors provided, try experimenting to see what works, and what doesn’t.
Well, if you just spam esc then it should implement Unity’s particle system into your game, andddddddd you should be set there. So, once you got that you basically click play and you should be good. 
If you ever need more help let me know.
