Is it possible to have _projectile that returns the projectile object that has been fired? (just like fired event handler)
this will make the event handler have much more uses, such as manipulating the projectile to not hit the target by changing its direction/velocity, or even making it easier to make Active protection system scripts without having to loop nearobjects constantly to check if there is any projectile heading for the vehicle.
