Hello. 🙂

Well I am making this ship game right and when You press the left button.

[AS]onClipEvent (enterFrame) {  
if (Key.isDown(Key.LEFT)) {  
this.\_x -= 5;  
this.gotoAndPlay(2);  
}  
}  
[/AS]

just a guess…

```auto
if (Key.isDown(Key.LEFT)) {
this._x -= 5;
if (!this.l) this.gotoAndPlay(2);
}
this.l = Key.isDown(Key.LEFT);

```

[! (logical NOT)](http://www.macromedia.com/support/flash/action_scripts/actionscript_dictionary/actionscript_dictionary007.html)

Key.isDown returns a Boolean (true/false), it simply assigns that Boolean to this.l, which will be evaluated by the **if** action.
