Hmm.. I'm not overly sure about this...
What about adding an fired eventhandler to the RPG guys, and a hit eventhandlers to the helo.
But they have to be within, that, 5seconds of each other.
And if they are, it runs the script..
It isn't very good, but it should work
But if the helo is hit with small arms fire in those 5seconds, it will go down...
What about using the camera bullet scripts, the but that follows the bullet, and if it is destroyed at the same rough postion (IE is is blowen up on it), it runs the script..
Or..... If the helos dammage is over 0.5( ? ), it runs the script..
You will have to experiment with the values, but when a RPG hits, it will cause a lot more dammage than a bullet.. And if the helo gets shot up so much it gets over 0.5. The tail rotar will "be hit".. Which isn't too good..
There must be a way of finding out what shell hit a unit....?
Good luck
