actionscript 3 - Remove discovered cards -

-

i'm creating flash "memory" game, idea discover 2 equal cards. fine, need make when cards discovered deleted. stay shown.

when try: removechild(_card.currenttarget._type);

i receive error: c:\...\memorygame.as, line 202 1119: access of possibly undefined property currenttarget through reference static type card.

here part of code:

    for(var l:number = 0; l < 2; l++)     {         _card = new card();         addchild(_card);         _snow = new snow();         _card.settype(_snow);         _card.x = _cardx;         _card.y = _cardy;         _cardx += _card.width + 50;         _card.addeventlistener(mouseevent.click, checkcards);         _cards.push(_card);     }  private function checkcards(event:mouseevent):void {      event.currenttarget.removeeventlistener(mouseevent.click, checkcards);      if(_firstcard == undefined)     {         _firstcard = event.currenttarget;     }     else if(string(_firstcard._type) == string(event.currenttarget._type))     {         trace("match");         _message = "match";         message_txt.text = _message;         _firstcard = undefined;         _currentmatches ++;         removechild(_card.currenttarget._type);

could me?

edit:

when use: removechild(_firstcard)

i receive error: typeerror: 

error #2007: parameter child must non-null. @ flash.display::displayobjectcontainer/removechild() @ memorygame/checkcards()[c:\users\rimante\desktop\gerase\gerase\memorygame.as:218]`

when use: removechild(event.currenttarget);

i receive error: 

c:\users\rimante\desktop\gerase\gerase\memorygame.as, line 217  1118: implicit coercion of value static type object possibly unrelated type flash.display:displayobject.

try

 removechild(event.currenttarget displayobject)  removechild(_firstcard displayobject)

the removal of _firstcard throws error because set var undefined. remove

 _firstcard = undefined;

or move line below removechild-lines.

if want delay try:

function removecards(firstcard:displayobect, secondcard:displayobject):void{     removechild(firstcard);     removechild(secondcard); }

and within event listener call

settimeout(removecards, 1000, _firstcard displayobject, event.currenttarget displayobject);

and remove removechild lines
