I have at the moment other irons to hammer, but if you find a solution, please drop a line.

PS: I used Naryvs approach, had no time to compare it with yours, but you find the code below:

how exactly does the AI behave differently with than without the script???
how can i imagine that?
if i set waypoints for a AI group, will they act spontaniously when they get in the surrounding of enemies, and ignore there waypoints?
or will they know automatically where all enemies are on the map, when they get spawned, and fly to that point?
