Problems with Sams

[WolfPire]

So ok i made an amazing A69 sams script.

But i got a lil' problem... Seems like the sams will keep spawning no matter if the user got off the vehicle or the vehicle dissapeared.

I tried to kill the timers in many ways and i couldn't seem to find a solution.

Could you guys please help me?

i want them to stop if there's no planes or helis near by

I not understand.

I want the sams to stop shoting if there is no vehicle nearby.

E.G: I came in a hydra and it dissapeared after i got off and exploded. Missiles are still spawning.

It kills timers only ( not destroy projectile )

Sorry for the HUGE BUMP...

But you had an error... I just fixed it, after a long time.

There was a very important conditional that wasn't made right... It looked like this:

if getVehicleType( source ) == 'Plane' or 'Helicopter' then 

Instead of this:

if getVehicleType( source ) == 'Plane' or getVehicleType( source ) == 'Helicopter' then 

Just pointing that out so it can be useful in future to people. Without it... The projectiles shot other type of vehicles too.
