Error 2025: The supplied DisplayObject must be a child of the caller
- by Mocca
Hi,
sorry, new to actionscript 3.
I have a display() function for an object rotator(image based like a QT object movie). It first saves the current image in a helper variable and then allocates a new image, from the library, beneath the old one. To get a nice crossfade effect, the old image's alpha is looped down via enter_frame and then removed.
Which is where there seems to be an issue with the display list, maybe recognizing oldImg's value as being already added? (it's not a first pass error)
Btw, do i have to remove the old image or can i leave it, for when it's being called up via the mouse position again? (the image number can get fairly large)
Does anyone have further insight? Thanks!
function display(num:Number):void //num: image number
{
...
oldImg = newImg;
ClassReference = getDefinitionByName("Class"+num) as Class;
imgBD = new ClassReference(0,0);
newImg = new Bitmap(imgBD);
images.addChild(newImg);
newImg.x=0;
newImg.y=0;
}
function onEnter(evt:Event):void
{
if (oldImg)
{
if (oldImg.alpha > 0) oldImg.alpha -= 0.15;
**else images.removeChild(oldImg);**
}
...
}
