How can I make actors spawn and move across the screen?

I'm making a game where you move a sword to block arrows from hitting a knight. How can I set my arrow actors to spawn continously faster, over and over again until you lose? I'm new to gamesalad.

You need to stick a rule in to stop it running out of control (something like a 'only do this if time between arrows is more than 0.01 seconds' rule).
