NPC's opening doors

[trevius]

Are you talking about for aggro'd NPC's, or for pathing NPCs?

I don't think there is a simple way to do it for aggro'd NPCs, but I have found that it isn't hard to make them do it for pathing NPCs.

What I do is make the pathing so that they pause for 1 second right outside the door before going through, and again pause for 1 second after going through it. This way, if they are patrolling through the door, they will pause for 1 second before trying to enter the door, no matter which direction they are coming from. Don't ask me why it works, but just by adding in the brief pause like that, it will let the door open before they walk through it. I haven't messed with it in a while, but that is how I have gotten it to work in the past.

I am sure you could also use scripting to do it if you wanted to be a bit more in-depth. But, pathing is probably the easiest way.
