[RESOLVED] removeChild problem

[pizza0502]

function btnClicked(e:MouseEvent):void {

    switch (e.target) {
        case Aplayer1 :
            setChildIndex(Aplayer1,numChildren - 1);
            TweenMax.to(Aplayer1, 0.5, {x:159, y:266, scaleX:1, scaleY:1, colorTransform:{tint:0x000000, tintAmount:0}});
            this.addChild(infoA1);
            infoA1.x  =  126;
            infoA1.y = 389;
                        //here i want to remove the movieclip that loaded from others buttonclicked
            this.removeChild(infoA3); 
            this.removeChild(infoA2); 
            this.removeChild(infoA4); 
            break;

        case Aplayer2 :
            setChildIndex(Aplayer2,numChildren - 1);
            TweenMax.to(Aplayer2, 0.5, {x:253, y:268, scaleX:1, scaleY:1, colorTransform:{tint:0x000000, tintAmount:0}});
            this.addChild(infoA2);
            infoA2.x  =  126;
            infoA2.y = 389;
            break;

        case Aplayer3 :
            setChildIndex(Aplayer3,numChildren - 1);
            TweenMax.to(Aplayer3, 0.5, {x:364, y:264, scaleX:1, scaleY:1, colorTransform:{tint:0x000000, tintAmount:0}});
            this.addChild(infoA3);
            infoA3.x  =  126;
            infoA3.y = 389;
            break;

        case Aplayer4 :
            setChildIndex(Aplayer4,numChildren - 1);
            TweenMax.to(Aplayer4, 0.5, {x:506, y:274, scaleX:1, scaleY:1, colorTransform:{tint:0x000000, tintAmount:0}});
            this.addChild(infoA4);
            infoA4.x  =  126;
            infoA4.y = 389;
            break;
    }
}

When i click Aplayer1 it will load infoA1 movieclip to the stage, click on Aplayer2 will load infoA2...but it will overlapping infoA1,infoA2...

i try to remove the child with the script above it will show up error 2025.

how to resolve this problem?

Always post the error message. No one has memorized that 2025 means "supplied object must be a child of the caller" (I just googled it).

Anyway, the error message tells you exactly what's wrong. You can't remove an object that isn't a child of the thing you are telling to remove it. You can use the contains function to see whether the child is there to be removed before removing it.

Sorry that I've forget the error message...

and i'm a newbie from AS3...totally...

what do you mean by container?

[5TonsOfFlax]

I didn't write 'container'. I wrote 'contains'.

contains is a method of DisplayObjectContainer, which tells you if a given DisplayObject is a child of that DisplayObjectContainer.

  //here i want to remove the movieclip that loaded from others buttonclicked
  if (contains(infoA3)){
     removeChild(infoA3); 
  }
  if (contains(infoA2)){
     removeChild(infoA2); 
  }
  if (contains(infoA4)){
     removeChild(infoA4); 
  }

But that's a lot of repeating. We could define a function:

function safeRemove(c:DisplayObject):void{
  if (contains(c)){
    removeChild(c);
  }
}

and then use it like:

  safeRemove(infoA3);
  safeRemove(infoA2);  
  safeRemove(infoA4);
