    Restart entire game

    Hello,

    I'm making a game and I want to restart the entire game after its finished.

    The movieclips are on stage with addChild function. So I thought maybe I can make a if statement and use removeChild to remove the movieclips. Now only one movieclip is removed and all the other are still on.

    Is there another way to restart the whole game with a button or something?

    Here is the code:

    Actionscript Code:
    package
    {
        import flash.display.MovieClip;
        import flash.events.MouseEvent;
        import flash.display.Sprite;
        import flash.utils.Timer;

        import flash.text.*;
        import flash.events.TimerEvent;
        import Card;

                    _firstCard = undefined;
                }
            }
        }
    }

    With the removeChild I get a error like this.

    Error #2025: The supplied DisplayObject must be a child of the caller.

    Tnx

    The code you posted does not have removeChild in it. Nor do I see anything about gameover or restart.

    The error you are getting is because you either called removeChild on the wrong parent, or with the wrong child.

    Hello,

    I'm sorry because I was trying all the time I removed it allready..

    Actionscript Code:
    _firstCard = undefined;
                    _currentMatches ++;
                    if(_currentMatches >= _totalMatches)
                    {
                        gotoAndStop(2);
                        timer.stop();
                        removeChild(_card);

    I know i dont have a restart in it yet, thats because I dont know how to do it at all...

    Dont know where to begin. I'm really stuck at this point :-(

    You could iterate through the displaylist and remove all the children which are Cards, but there's a better way. Each time you create a card and put it on the displayList, you put it into an array of your cards also. When you want to remove all cards, iterate through the array, removing each.
    Code:
    package
    {
    	import flash.display.MovieClip;
    	import flash.events.MouseEvent;
    	import flash.display.Sprite;
    	import flash.utils.Timer;
    	import flash.events.Event;
    	import flash.text.*;
    	import flash.events.TimerEvent;
    	import Card;
    	import Computer;
    	import Muis;

    Don't forget to reset your _cards array when you start a new game.

    It worked!

    After they all matches to cards are gone

    I'm making a restart button now like this:

    Actionscript Code:
    btn_restart.addEventListener(MouseEvent.CLICK, onMouseClick_2);

    function onMouseClick_2(e:MouseEvent):void
    {
        for (var i:int = 0; i < _cards.length; i++){
        addChild(_cards[i]);
        }
    }

    This code is on timeline btw.

    When I click the button the cards are up again
    But they are not reset. they are the same as I left them and not upside down.

    I know I have to reset the Array, Timer, ect.

    But dont know how at this moment. Making a game in flash is very hard if you action script is not that good

    Can somebody help me out?

    Tnx

    No dont know how to reset cards...

    Timer wasnt that hard...

    timer.reset();
    and when you want to start it again
    timer.start();

    But still dont know how to reset the cards in a good way

    If you don't want to re-arrange the cards, then simply go through your _cards array and tell each card to go back to the initial frame or the flipback frame. If you DO want to shuffle your cards, or generate new ones, then you should

    1. reset your currentmatches
    2. call shuffleCards again
    3. put your cards back on the display.
