[AS3] Can't get replay button to work

an Array is just a list of references.
The children on the stage have to be removed using the removeChild() method.

A simple way to do this is with a while loop

// "container" is a Sprite within which are all of your child objects
while(container.numChildren > 0)
{
    container.removeChildAt(0);
}

In afz's example, "container" is whatever Sprite or Movieclip you added the children to when you created them. In your original code you tried to do this with "ba" but if "ba" is an Array, it's not part of the display list.

If "container" has children that you don't want to remove because they aren't in the "ba" Array I think you can do this:

for (var ch:MovieClip  in ba) {
  container.removeChild(ch);
}

I SEE.... It looks like my problem is I'm not placing the bears in a container, I've just been placing them on the stage (...or randomly off-stage to be specific)

I went ahead and added a container (bearContainer) and changed addChild to bearContainer.addChild; However, it's now causing a lot of problems.

Is there a way to remove the children from the stage, or do I need the in a MovieClip container to remove them?

Thanks

Also, lauri wrote some code for me, including a removeObject function, which you can see here:

function removeObject(obj:MovieClip, objectArray:Array):void 
{
    // Remove listener.
    obj.removeEventListener(Event.ENTER_FRAME, enterFrameHandler, false);
    // get array index
    var i:int = objectArray.indexOf(obj);
    // remove emement from array with index number
    objectArray.splice(i, 1);
    // remove object from stage
    removeChild(getChildByName(obj.name));
}

Is this something I could use to remove all children from the bear array (ba)? I tried to use the function, but I couldn't figure out how to write it.

EDIT:

I think I've thought of a way to remove all the bear children without placing them in a container... however it still isn't working... tell me what you think of this method:

I created a variable called "bearsOnStage" which keeps track of how many bear children are on the stage at any given time (I traced the value, and it works great).

Then I wrote this loop, which uses the removeObject function:

for(var i:uint = 0; i < bearsOnStage; i++)
{
    removeObject(bear[0], ba);
}

I don't get any error messages when I run the swf, however, no bears are removed either.

What am I missing? it's the same line of code I use for when the bears get shot:

removeObject(bear, ba);

It works great when the bears are shot, but it's not doing anything in the loop...

Sorry if i'm missing something really dumb

EDIT:

I just realized that "bear" doesn't refer to the movieclip unless it's inside a function that's receiving a movie clip. Example:

function moveBear(bear:MovieClip):void
{
    direct(bear, guy1);
}

The variable I created for a new bear movieclip child is "nb", but I can't figure out how to reference the child display object inside of a new function...

If you added them to the stage, then the stage is your container.

for(var i:uint = 0; i < bearsOnStage; i++)
 {
     removeObject(bear[0], ba);
 }

The trouble here is that "bear" isn't an Array, is it? So using bear[0] doesn't make sense.

Maybe this, since "ba" is an Array that contains bears, right?
removeObject(ba[0], ba);

You're awesome rrh, that totally worked

I feel foolish for not noticing that :/ I don't know much about actionscript, but I should know that you can't call on the index of a movieclip, lol
