How about

```auto
if (parseInt (lives) &lt; 1) gotoAndStop (2) ;[/As]
```

hmm, doesn’t seem to work, and just wondering, what does parseInt mean?

parseInt converts a string to an integer.

The code Ilyas provided you is right. Im guessing that its not working because of the way you are checking for that statement. That if statement needs to be continually checked, using for example an onEnterFrame handler or setInterval. Something like this should work

```auto
this.onEnterFrame = function() {
	if (lives<1) {
		this.gotoAndStop(2);
		delete this.onEnterFrame;
	}
};

```

Remove this line from your actions layer:

```auto
if (parseInt (_root.lives) < 1) gotoAndStop (2) ;

```

Then, place this line inside the onClipEvent(EnterFrame) of your enemy1 movie clip:

```auto
	if (_root.lives < 1) _root.gotoAndStop (2) ;

```

thanks claudio 🙂  
by the way, do you know why those missles are not exploding when they hit the ground?

```
if(this.hitTest(_root.ground) and !exploding) {
	exploding=true;
	_root.enemy+i.gotoAndPlay(2);
	_root.lives -= 1;

```

}

is what i have for that on the missle mc

Replace:

```auto
if(this.hitTest(_root.ground) and !exploding) {
		exploding=true;
		_root.enemy+i.gotoAndPlay(2);
		_root.lives -= 1;
}

```

for:

```auto
if (this.hitTest(_root.ground)) {
		gotoAndPlay(2);
		_root.lives--;
	}

```

i prob shouldn’t be asking so many questions, or changing the topic of the thread like this, but i have just one more…

do you know if it is possible, to limit the number of lasers you can shoot at a time to 3, until they hit the top of the screen like in that game space invaders where you have to shoot down the aliens in rows, you only get one shot until your laser hits the top…

I made a few changes. You can only shoot again if you hit an enemy or the laser gets off the screen. I didnt dig into the code to check for unnecessary code though.
