Doing anything but copying the data from the event to your own bytearray
buffer object is a disaster waiting to happen.
TCP is a stream based protocol, you can get chunks of any length each
time the event is reviced. Assume that the chunks are random length and
piece them together in a buffer

Hi Theodore,
When you say 'addChild(mySprite)' mySprite *is* the child of
something: the instance you call addChild on (addChild(mySprite) is
equal to this.addChild(mySprite))
To remove mySprite you have to call removeChild(mySprite) on the same
instance.

Something like:

Inside your loop, you can add the sprite to a movieclip and give each movieclip

A peculair twist now is that these bar sprites are being sent to the back

lines in the back... these lines now show on top of the bars...
I agree with Mr. Tom Rhodes. Storing references to your buttons in an
array is far better than trying to create and use dynamic instance
names like bar+i. You can tack on data properties to the buttons as
well, so they have information about themselves that travels with them.

Glad you got it fixed. I'm late to the discussion, so didn't
contribute anything yet--but I will now :-)
I think it depends on the circumstances:
If you are not manipulating the child sprites in any way, just adding
them at the start, removing at the end and possibly listening for events
on them, why would you want to use more memory by storing the sprite
instances in an array or a vector when
addChildAt(child:DisplayObject, index:int)
So:
this.addChildAt(barMom, 0);

You can use the addChildAt method and tell it where to add the object in the

addChildAt(objectName, 0); will add the objectName to the bottom of the display
