need a working civilian AI (more info inside)

[Crohns Racing]

right now I have a zombie AI thats working, very simple to make, where the zombie object just runs at the civilian object, but I can not find any way to make the civilian run away, or cannot find any working AI for it.
any help is wanted and appreciated.

if you want the civilian object to run away from the zombie you coud try to use something like this if point_distance() < "your range" speed = "" direction =""

read up on finite state machines to make complex AI broken into simple bits.
So you create one large step event which check each state variable (best set as defined constant) then you can easy set state from any place in code and easily add more and change states for more behaviour. Use scripts so you can easy edit each behaviour as separate script
