Should be in Scripting section........
Ok.You'll need to set the triggerzone main AI to plrinzoneactivateused.fpi.
Then give the car this script:
;CoffeeGrunt Scripts
;header desc=if activated,destroy
;Set is Explosive to YES
;set destroy script to flamable.fpi
;triggers
:state=0:state=1
:state=1,activated=1:destroy
;end script
And the Decal needs this script, it'll play once then disappear:
;coffeegrunt scripts
;header desc=if activated, play once then destroy
;Set sound 1 to your explosion sound
;triggers
:state=0:state=1
:state=1,activated=1:rundecal=0,3dsound=$1,state=2
:state=2:destroy
;end script
Set both entity names the same, so they are both called something like *explosion* or *cardestroyed*. Then set that in the If used box in the TZone's properties, don't forget to set the sound 1 string as your missile sound.
