actionscript 3 - AS3 - Loading multiple videos into the same container - addChild removeChild -

-

this function loads specific video movieclip container @ 0.0 using video class.

public var mainvideo:simplevideo;  public function loadvideo(videostring:string) :void{     mainvideo = new     simplevideo("videos/"+videostring+".flv","",true,video_container.positionmc);     video_container.addeventlistener(mouseevent.mouse_down,controlvideoplayer);     addchild(mainvideo);     trace('adding new video container'); }

i'd preferably check, each time video loaded, see if there video loaded. , if there is, remove it, , add new video.

i've tried using removechild() in variety of ways, doesn't seem work correctly.

would use removechild(mainvideo)? video_container.removechild(mainvideo)? , how able check if there existing mainvideo?

any appreciated!

-update- if try , use removechild(mainvideo) error:

typeerror: error #2007: parameter child must non-null.
@ flash.display::displayobjectcontainer/removechild()
@ main/removevideo() @ methodinfo-127()

if add video container movieclip rather onto stage, , container has 1 instance of simplevideo in display list @ time, do:

if( myvideocontainer.numchildren > 0 ) {     myvideocontainer.removechild( myvideocontainer.getchildat( 0 ) ); }

a bigger issue though how simplevideo class using cleans up. video classes have cleanup or kill function removes listeners , cleans netstream. think you'd need call removing video instance container.
