Hey Calkins88,
First set the enemies to "always active" in thier properties through the editor. Next, open up your characters main script.
In lines 500-502, you'll notice a command "plrdistwithin=x". This command will have something happen to the player when they are a certain distance from the entity. (In this case, it is telling the zombies to notice the player) Change the number to something higher, 100= 1 segment.
So, setting "plrdistwithin=1000" in those lines, will have the zombies start approaching the player from 10 segments away
