Clear all elements in the specified display object

To prevent memory leakage, you may need to clear unnecessary display elements. If these elements need to be cleared include recursive sub-display containers of objects, this may not be collected by GC, so the following function can clear all the display containers:

Code:

Function clearDisplayList (container: DisplayObjectContainer): void {

Var child: DisplayObject;

For (var I: Number = container. numChildren-1; I> = 0; I --){
Trace ("container:" + container. name + "--> I:" + I );
       
Child = container. getChildAt (I );
               
If (child is DisplayObjectContainer ){
// Recursive call
ClearDisplayList (DisplayObjectContainer (child ));
                }
               
Container. removeChild (child );
        }
}

To clear all the elements in the scenario, use clearDisplayList (stage).
