AS3 Remove items in an ENTER_FRAME

I have generated random bubbles, I used a code I found in the net. Now I want a click event that will hide a random bubble.

Here is exactly the code I used,

http://good-tutorials-4u.blogspot.com/2009/04/flash-bubbles-with-actionscript-3.html

I got the bubbles running good...

I have tried this, and so far no luck..

addEventListener(MouseEvent.CLICK, eventListener);


function eventListener(eventObject:MouseEvent) {

        bubbles[i].splice(i,1,bubbles[i]);

}

I tried using an array but it returns me this output TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/removeChild() at Function/()

TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/removeChild() at Function/()

try this 

bubbles.addEventListener(MouseEvent.CLICK, eventListener); // place this listener in moveBubbles function.

function eventListener(eventObject:MouseEvent):void {

     eventObject.currentTarget.visible = false;

}

Just a minor revision on Baris Usakli's code here, this is if you want the one that was clicked on to be removed.

var bubbles:Array = [];
function makeBubbles()
{
    for(var i:int=0;i<100;i++)
    {
        var bubble:Bubble = new Bubble();
        bubbles.push(bubble);
        addChild(bubble);
        bubble.addEventListener(MouseEvent.CLICK, eventListener);
     }
}


function eventListener(eventObject:MouseEvent) {

    var clickedBubbleIndex:int = bubbles.indexOf(eventObject.currentTarget);
    parent.removeChild(eventObject.currentTarget);
    bubbles.splice(clickedBubbleIndex:int, 1);

}

If you have the bubbles in an array this should work.

var randomIndex:int = int(Math.random() * bubbles.length);
parent.removeChild(bubbles[randomIndex]);
bubbles.splice(randomIndex, 1);

Notice that you have to remove the bubble from the display list too.

You can try creating a new array without a random element from the original array. Then just reassign the old array to the new one, e.g.

// get the random index to remove element at
var randomIndex:int = 0 + bubbles.length * Math.random();
var index:int = 0;

// create new array containing all apart from the chosen one
var newBubbles:Array = [];
for each (var item:Object in bubbles) {
    if (index != randomIndex) {
        newBubbles.push(item);
    }
    index++;
}

// here you go new array without one random item
bubbles = newBubbles;

Or something like these.
