Just bought a new flash 8 action script 2.0 book and I’m going through the custom classes section.

This is Motion.as, say hello he’s only a few hours old!

class Motion extends MovieClip{  
function Motion(){  
trace(“Motion class instantiated”);  
}  
function updatePosition():Void{  
this.\_x++;  
this.\_y++;  
}  
function onEnterFrame():Void{  
this.updatePosition;  
}  
}

When I link him from the fla file and run it’s doing the trace comment once, but it’s not doing the movement. Am I missing something.

Identifier = MotionShape  
AS 2.0 class = Motion
