Its still posible to do that with events easily.
First of all, back in V8 the events were an add-on entirely different from the events now. They had a specific even for that
Secondly, It is very easy to do even now.
OnPlayerTouch (invis. bricks around the turret) -> NamedBrick -> SpawnProjectile -> [Weapon] -> coordinate directions of the brick (just an estimate will do)
Owned :P
