hi,

im having trouble getting the following to happen in G.E.C.K on my mod im working on, this is the series of events i wish to be played out,

 

Player heads towards Vault door.

When player is within a certain range, a npc will walk towards a Comm panel and radio to open said door.

 

Inside will be another NPC which will be operating the vault interior automatic defence systems ( basically a guy at some control panels inside the booth in the vault room, there's already wep turrets placed around the vault access room ) and again, i would like him to open the vault doors on player approach to the door itself ( upon exiting ).

 

There is a catch, i need a control panel in the booth to open the door as well, in the event the player wishes to kill everyone for fun, otherwise they'd be sealed inside.

 

 

Im assuming this is possible due to megaton doors being opened when the player approaches, and the Tenpenny comm system. how ever im starting to get bald from pulling my hair out over this ><.
