Limit number of projectiles a player can launch?

[AVRe]

My game allows a player to roll a ball. I'd like the player to only be able to roll one time until the ball leaves the screen then the player can roll again. To roll a ball I have the player press the spacebar. Everything works fine but if you press the spacebar very quickly the game will roll numerous balls and I'd like there to always only be one available for the player to roll. Thanks for any suggestions!

Hi AVRe. Only allow the action if "last ball is destroyed".

Thanks, sounds perfectly logical but where on event editor do I include that "if" statement? It is a keypress action. Is there somewhere I can "never allow spacebar keypress" if ball is visible? I'm pretty new to this but learning. Thank you.

When you make your projectile and put it on the screen, un-check "create at start".

Last projectile has been destroyed
*Set flag 1 on

Player pushes Space Key
+Flag 1 is on
*Create projectile at the active.

I hope this helps.

You add extra conditions by right-clicking the condition and clicking "Insert".

Conditions (Launch ball: Spacebar; ball gets destroyed):

* Upon Pressing "Space bar"
+ Number of Active= 0
