While

[BlKnight]

Stefan, you need to make while like this:
Instead of it being in a event to work, make it so it works indepentdantly. So lets say I have a variable on. A different NPC sets on to 1. Another NPC has it so while(on=1) {script}, the other NPC has no other script either. SO basicly it actively checks when on = true, and when on = false it stops.

I thought that was in there already, but I'm posting this, so learned otherwise.
