Hi,
Best practices say that when done with an event listener, it should be
removed. If you're not removing it (them) anywhere else, you should
remove it with your "destroy" function. This is also an excellent time
to kill any streams, stop sounds, stop timers, etc. In fact, it's
recommended that your AS3 scripts do clean up things like this. In AS3,
removing items from the display list doesn't destroy the objects like it
did in AS2.
I try to include the following in any movie clip that is loaded:
---
function unloadHandler(event:Event):void {
/*
in here clean things up such as
* null out any references to loaded content
var myVar = myLoader.contentLoaderInfo.someVar
=> myVar = null;
* unload any swf's that were loaded so they can also clean up on
unload
* stop any sounds from playing
this might mean SoundMixer.stopAll();
or it might mean stopping a moiveclip (like with a .mov
on it)
* close any LocalConnections, NetConnections, NetStreams
* return any global properties to their default
* null out any Camera or Microphones
* removeEventListener for any that weren't by their natural flow
* clearIntervals
* stop any Timers
*/
root.loaderInfo.removeEventListener("unload", unloadHandler);
}
root.loaderInfo.addEventListener("unload", unloadHandler);
---
This could be adapted for classes that are instantiated.
