Gas trap between 2 doors

Gas Trap between 2 doors
Generic Trigger on enter script

What it does: PC or Creature stepping onto trigger is checked for a key.

If No key, closes both doors, locks em, and starts filling area between them with Poison Gas (Also informs PCs of whats going on)

If got Key, Trap is delayed by 30 seconds, PC informed that key Glows and Hums, then informed when trap goes off. // Gas Trap in Hall or Small Room between 2 Doors // // Place on a generic trigger "On Enter" script // // Other Items Required: // 2 Doors Tag "GasTrap1" and "GasTrap2" // 2 Waypoints Tag "waypt1" and "waypt2" // 1 Placeable Invisible object Tag "DoorLocker" in vicinity of 2 doors // 1 or more Keys that the players can find Tag "GasTrapKey" // // By Mordrake of COR // 17 Sept 02 // Lots of help from: // Wolfe13, IceBerg , Tcoz , tjm // // Note: if you want this trap to spawn gas that can harm Monsters as well, edit factions to have a // "Placeable" faction, which is hostile towards them.

How I used it
I placed a section of hallway just inside a large cave complex.. the first door in the hall starts of unlocked and is extreamly hard to Pick or Break Down.

Between that door and the next (Which starts off locked(not too hard) and trapped (not that difficult either), is the Trigger, 2 waypoints used for the Gas to come from, and the invisible object used to close the doors.

This set up almost makes the hallway a "One Way" into the caverns untill the Party finds a key.

You can make it a true "One Way" by making the first door "Plot" and unpickable.
