What is the "Function Anonymous" ?
I´m getting a lot of errors when I use removeChild from AS3. And many of them display this "Function anonymous" like this:
Can´t I remove a child?

TypeError: Error #1034: Falha de coerção de tipo: não é possível converter Function em flash.display.DisplayObject.

I´m trying to go from one class to another (the menu screen to the game) and I´m getting the error above.

The Player.IO error log will show you the context of the error.

The method that does error is however the result of an handleMessageHandler

I always get this error when I use a removeChild.
Can´t I remove a child when I use PlayerIO?

Paste the code that errors, let's look at what you are doing.

I´ll try to explain

I´m doing this:

Main class -> calls Menu class -> calls ChatLoby class (instantiate the lobby and chat).
When 2 players join a room, I go to the Formation Screen (another class), where the players choose the formation for their teams (it´s a soccer game):

Code: Select all

      if(Main.isOnline)  // a variable to tell me if the game is online or offline(2 players on same machine)
         {
            startBt.visible=false;
            startBt.removeEventListener(MouseEvent.CLICK,onStart);
            startBt.removeEventListener(MouseEvent.MOUSE_OVER, overPlay);            
         
            okA.addEventListener(MouseEvent.CLICK, okAbt);
            okB.addEventListener(MouseEvent.CLICK, okBbt);
            
            Main.connection.addMessageHandler("ok1", function(m:Message, ok1:Boolean){
               trace("oka");
               ok0=ok1;
               trace("a: " + ok0 + ok00);
               if(ok0 && ok00)
               {
                  removeListeners();
                  Main.gameState="jogo";
                  Main.formationA=formA;
                  Main.formationB=formB;
                  dispatchEvent(new Event("Init",true));
                  parent.removeChild(this);      
               }

            })         


So, when I use the parent.removeChild(this), I got this error
PS: this error happens only when I use PlayerIO. This game works ok offline (2 players at same machine), but now I´m trying to implement PlayerIO and some things (like removeChild) give this error...

Thanks!

When calling an anonymous method the this reference is lost as the scope is not preserved.

There are two easy ways to solve that, either call a private method on your class directly or use the below hack.

Code: Select all

var that:Type = this;
....(function():void{
   that.parent.removeChild(that)
})

Oh yeah!!!
Now I understood!!!!
This is why I´m getting some errors... thanks a lot!
SOLVED!
