Hello,  
I can’t figure out which way to go to have a good firing from a weapon with a rate of fire…  
I have a hero class where i have, inside an onEnterFrame function :

```auto

if (Key.isDown(Key.SPACE) && fireInterval == false) {
			var myInt = setInterval(this.launchMissile(), this.missileRate);
			fireInterval = true;
		}
		if (!Key.isDown(Key.SPACE)) {
			clearInterval(myInt);
			fireInterval = false;
		}

```

the launchMissile function is a simple attachMovie function.  
Now for some reason, even if i hold the space key down, the interval isn’t working… Help 😃
