Hi board,

I have a class which controls a movie clip. The movie clip has a button in it. The problem is that I cannot use the class members in the onPress function of the button.

[AS]  
class Controller {  
private var id:Number; // I have tried public also  
private var myClip:MovieClip; // The clip that has the button

public function Controller() {  
// I have got the reference to the MovieClip that contains the  
// button.

myClip.myButton.onPress = doSomething;  
}

public function doSomething() {  
trace(this.id); // \<— does not work. I tried without _this_  
// the function is being called so thats not a problem  
// Only the _id_ is not accessible.  
}  
}  
[/AS]

Thanks a lot.

Cruiser.

In AS 2.0 classes, the _this_ prefix is no longer necessary as it was in AS 1.0. So try this:

```auto

class Controller {
private var id:Number;
private var myClip:MovieClip;
function Controller(){
myClip.button.onPress = doSomething;
}
function doSomething():Void{
trace(id);
}
}

```
