Hi!

Currently I've got this script which will call a vertibird, make it bomb and then it will fly away, but the vertibird won't even appear, nor will it add a single bottlecap into my inventory as a debug. Here is the script (that StartBombing is a global var which is set to 1 if a button is pressed):

scn PlayerVertibirdBombing02SCRIPTshort doOnceBomb02float timerBomb02short firingFlagBomb02float fireTimerBomb02ref VertibirdCallBomb02REFERENCEshort doOnceBegin gameMode	if (StartBombing == 1 && doOnce == 0)				player.additem f 1;DEBUG!!!		set VertibirdCallBomb02REFERENCE to player.PlaceAtMe PlayerVertibirdBomb02;Place Vertibird at player		VertibirdCallBomb02REFERENCE.SetAngle x 0 ;Make sure the Vertibird fires on the ground		VertibirdCallBomb02REFERENCE.SetAngle y 0 ;Make sure the Vertibird fires on the ground		set doOnceBomb02 to 1;Enable doOnceBomb02 to engage bombing run		set timerBomb02 to 1;Set the timer for the bombing run		set doOnce to 1	endif	if (doOnceBomb02 == 1)		if (VertibirdCallBomb02REFERENCE.HasLoaded3D != 0)			VertibirdCallBomb02REFERENCE.playgroup Forward 1			set fireTimerBomb02 to 0.5;vertibird going to shoot for this long once in position			set timerBomb02 to 12	;vertibird takes this long to get into hovering position			set doOnceBomb02 to 2		endif		elseif (doOnceBomb02 == 2)		if (VertibirdCallBomb02REFERENCE.isAnimPlaying Forward == 0)			VertibirdCallBomb02REFERENCE.disable		;disable the vertibird when it's done playing its forward animation			set PlayerVertibirdBomb02QUEST.StartBombing to 1			set doOnceBomb02 to 4		endif				if (timerBomb02 <=0)	;vertibird in position to start firing			set timerBomb02 to 4;vertibird hovers for this long before flying away			set firingFlagBomb02 to 1			set doOnceBomb02 to 3		else			set timerBomb02 to (timerBomb02 - GetSecondsPassed)		endif	elseif (doOnceBomb02 == 3)		if (timerBomb02 <= 0)			set doOnceBomb02 to 4		else			if (firingFlagBomb02 == 1)				if (fireTimerBomb02 <=0)					VertibirdCallBomb02REFERENCE.fireWeapon DLC03VertibirdMissileLauncher					set fireTimerBomb02 to .5					set firingFlagBomb02 to 2				else					set fireTimerBomb02 to (fireTimerBomb02 - GetSecondsPassed)				endif			elseif (firingFlagBomb02 == 2)				if (fireTimerBomb02 <=0)					VertibirdCallBomb02REFERENCE.fireWeapon DLC03VertibirdMissileLauncher					set fireTimerBomb02 to .5					set firingFlagBomb02 to 1				else					set fireTimerBomb02 to (fireTimerBomb02 - GetSecondsPassed)				endif			endif			set timerBomb02 to (timerBomb02 - GetSecondsPassed)		endif									set timerBomb02 to (timerBomb02 - GetSecondsPassed)		endifEnd

At the console, does Show StartBombing return a 1 ?

Nope, it returns a 0.

Sounds to me like where ever your setting StartBombing to 1 is the issue, because its not setting it. Show us the script for the button that occurs at.

Will do:

EDIT:
I've found the solution (with help), here are the scripts (one is attached to a vertibird):
