[SIZE=3][FONT=Calibri]Hi,[/FONT][/SIZE]
[SIZE=3][FONT=Calibri]I have problem with accessing objects in AS3.0.[/FONT][/SIZE]
[SIZE=3][FONT=Calibri]Suppose I write this code on MainTimeLine:[/FONT][/SIZE]

 
var sprite1:Sprite = new Sprite();
var sprite1Child:Sprite = new Sprite();
sprite1.addChild(sprite1Child);
addChild(sprite1);
 
 
//custom class
var myMC:myMovieClip = new myMovieClip();

[SIZE=3][FONT=Calibri]Now from myMC I want to reference sprite1Child object.[/FONT][/SIZE]
[SIZE=3][FONT=Calibri]How?[/FONT][/SIZE]

[SIZE=3][FONT=Calibri]To access sprite1 I use this code inside myMC:[/FONT][/SIZE]

 
this.parent.getChildAt(0)

[SIZE=3][FONT=Calibri]That works, but I can’t reference sprite1Child which is inside sprite1.[/FONT][/SIZE]
[FONT=Calibri][SIZE=3]Thanks,[/SIZE][/FONT]
