I need a script that will trigger a trap on the death of an npc. The Original trap Script is as follows:

scn ARTrapGasEmitter01SCRIPT

; spurt gas on activation

short init
float timer
short next
ref mySelf
ref myParent

float fTrapDamage
float fLevelledDamage
float fTrapPushBack
float fTrapMinVelocity
short bTrapContinuous

begin onActivate

if init == 0
set mySelf to getSelf
set myParent to getParentRef
set init to 1
endif

if isActionRef player == 0 && isActionRef mySelf == 0

set init to 2

; set up the damage values
set fTrapDamage to 10
set fTrapPushBack to 0
set fLevelledDamage to 0.125
set fTrapMinVelocity to 20
set bTrapContinuous to 1

set timer to 8
set next to 1
playgroup forward 1

endif

end

begin gameMode

;daisy-chain
if next == 1 && timer <= 7
set next to 0
myParent.activate mySelf 1
endif

if timer <= 0 && init == 2

playgroup forward 1
set timer to 10

endif

if timer > 0
set timer to timer - getSecondsPassed
endif

end

Give the trap a unique RefId (like DeathTrapRef or something) and make it a persistent reference. The attach a script to your NPC that will activate the trap. It should look something like:

scn DeathTrapActivateScriptBegin OnDeathActivate DeathTrapRefEnd

Please use CODE tags around code to preserve white-space; it makes it massively easier to read and debug.

Anyway, you're never getting to set init to 2, because you're checking IsActionRef player == 0 - meaning this won't work when the player activates it. Plus you have IsActionRef MySelf == 0 for no reason; this can't activate itself. This will activate its parent (which is a little odd, but I think I see where you're going with that). Change that line to IsActionRef player || IsActionRef (my-child), and it should work, I think. Or just don't bother checking who the action ref is, since it's very unlikely to be anyone but the player or the reference's child.
