Grunt Despawn Problem

[Shadowfied]

I really don't wanna show screenshots of my map yet but I guess it's the only way to show the situation properly:

First off there are path nodes but they are just below the camera in the screenshot and I want him to walk straight right here.

So he enters the room (the door to the left) and I have another script area in that room which enables the despawn script area, cause otherwise he would despawn immediately. So, the player hides, he walks in the room, he walks out, despawns. However, if the player RUN OUT when he goes in, and the grunt starts chasing the player, he will despawn once he runs in the marked area.

What I would need is some way to disable the script area if the player is close.

And by typing this I just got an idea...if the player runs out of the room, I can make a script area which disables the grunts despawn area...

And I only know pretty basic scripting.
