It behaves exactly like the function in MW2.

Update: Fixed an issue by making it spawn only one helicopter and move it when needed.

    

MagicBullet(weapon, start, end, owner)

{    angles = VectorToAngles(end - start);

    if(!isdefined(level.bulletspawner))

    {    level.bulletSpawner=spawnHelicopter(owner, start, angles, "cobra_mp", "tag_origin"); 

        level.bulletSpawner SetMaxPitchRoll(360, 360); 

        level.bulletSpawner hide();

    }

    level.bulletSpawner.origin = start;

    level.bulletSpawner.angles = angles;

    level.bulletSpawner.owner = owner;

    level.bulletSpawner setVehWeapon(weapon);

    bullet = level.bulletSpawner fireWeapon("tag_origin");

    level.bulletSpawner.origin = (0,0,100000);

}
