how do i permanetly lock a door after it has closed once???

i think it is closetarget (could be wrong) linking the door to a target_deactivate then back to the door


func_door:
targetname door1
closetarget deact1

target_deactivate:
targetname deact1
target door1

but then you need a button (func_button or trigger_once because it is i use once door) to open it.
thinking about it you could just use a trigger_once to open it (when it is not on toggle) and once it is closed there is no way to open it again

wel i have in my map a door thats triggerd by a destroyable object once the object is destroyed the doors close but they need to remain closed

if there is only 1 destroyable object, or one for every time you want the door to open and no other entities triggering the door then you already have the effect that you want

there is 1 destroyable object
but when the door closes it opens again after a few seconds
its suposed to remain closed

that does not sound right. are you sure that you made the door correctly? or are there any other entities triggering the door?

Give your door the START_OPEN spawnflag, and give it the key/value wait -1. Then target the destructable at the door. Voila.

it works thanks but the area portal wont work tho any idea's?

Area portals might be flooey with one-use doors. Did you texture the portal brush with common/skip except for one system/areaportal face?
