limiting times an event can happen?

[game_mate]

is there a way to creat an event that can only happon once or after a certain time. like a collition event or a key down event(such as jumping)?

Create an actor variable called "canShoot".

Set it to 1.

Your shoot key checks if canShoot is 1.
If it is 1 it fires a bullet then sets camShoot to 0 and starts a timer.
The timer event sets canShoot back to 1.

If the timer is set to 1000 you can only shoot a bullet evey one second!
