Wouldn't that cause a crap load of missles?
If so, here's a way to fix it:
Option A:
Make a floor of invisible plates, when a player touches it, turn off collision, then turn it back on 1-2 seconds later.
Option B:
Instead of firing with an onPlayerTouch, send a relay t the turret brick and use these events on the turret:
[X] 0 [0] onRelay > Self > toggleEventEnabled > [ALL]
[X] 1 [2000] onRelay > Self > toggleEventEnabled > [ALL]
[X] 2 [0] onRelay > Self > fireHomingProjectile > (Projectile)
Option A Details:
Fires projectiles more often when the player is moving
Could cause floor problems
Fires at multiple players
Option B Details:
Fires projectiles at a consistant rate
Uses less output events
Fires one projectile at a time
