RemoveChild issue in AS3

**RogerFielden** · 15-05-2009

I have an array of MovieClips that i am checking in an enterFrame event and wanted to generate a maximum of 5 childs in a clip called 'placeholder' using a button (placeCloud_1). and whatever the childs will 'float' to the top of the stage. when the y=0 the child must be removed (using the function checkPos() ) so i can add another child without exceding the number of 5 childs. Everything works, exept for the removeChild! i've tried removeChild(this) , this.removeChild(this), parent.this.removeChild(this), parent.this.removeChild(mc), placeholder.removeChild(this) etc... and nothing works.

When using (this) it throws TypeError: Error #1034: Type Coercion failed: cannot convert global@2f6710d1 to flash.display.DisplayObject. whats this issue can anybody help me

You need to embed the following code in your program, this will give you the expected result.

Code:

event.target.parent.removeChild(event.target);

and you need to use the best way to clear out a display with this:

Code:

while(myMC.numChildren > 0) removeChild(myMC.getChildAt(0));

Make a container movieclip, attach it, and attach your list items to the container.and If you're looping through a DisplayObject and are basing the loop on numChildren, then no need to remove children as the value of numChildren.

I found that this is a similar problem to what I was having,The code you have given will help to removes the single instance of the movie clip, but not all instances.Once this has been finalized you would be looping through a DisplayObject and are basing the loop on numChildren, then not all of the children are removed as the value of numChildren changes as you remove the children.

I have used the following way to remove all the children as follows:

Code:

var count:uint = mySprite.numChildren;
for(var i:uint=0;i<count;i++){
mySprite.removeChildAt(0);
}

Here the Used 0 (zero) index for removeChildAt as everytime you remove an item, it shifts everything in the display list down by 1.

Thanks for the reply, when i apply your given code in the program at that time it works only for some children's but i was unable to remove children's from the others. Is it possible to delete the holder clip entirely and then recreate it when you press the button to display the list.
