How do I make a firing gun.

In the platformer im currently working on im trying to make a wall turret that fires continuously. Ive managed to make the gun fire once but I cant figure out how to make it repeat.

The way ive made it fire is that when the player passes a certain point it will spawn the projective which has a bullet behaviour and fire towards the player. Is there a way i can just tell it to keep repeating this?

Make the bullet destroy when it touches another object and then make this event:

When "Bullet" is "On destroyed" -> "Turret" Spawn "Bullet"

that should make a loop
