Class Question

[jenn_tran]

its the error i get quite often when i modify the .as file 1180:Call to possibly undefined method shuffle.

[sparX]

The method is identified as
'shufflePieces'
jenn.
Call

puzzle.shufflePieces();

on the mainTimeline.

Also, make sure you saved the file when you edited it.
Flash does that stupid thing of not saving files before you build...

Do i put it after all the button codes? i'm getting 3 1120 errors now all saying Access of undefined property puzzle.

Now i'm trying to add drag and drop function to the puzzleObject (pieces) i add the code below to my class file but when i call the function to my main timeling i get this error 1136 incorrect number of arguments. expected 0
Any idea what i'm doing wrong?? thank you Jenn

// Adds Drag and drop to pieces
        
        public function dragDrop()
        {
            addEventListener(MouseEvent.MOUSE_DOWN, drag);
        }
        public function drag(event:MouseEvent):void
        {
            startDrag();
            stage.addEventListener(MouseEvent.MOUSE_UP, drop);
        }
        public function drop(event:MouseEvent):void
        {
            stopDrag();
            stage.removeEventListener(MouseEvent.MOUSE_UP, drop);
        }

Almost jenn.
When you get an error from something, paste the whole error into your reply, it usually contains other info that is useful.
Also include the code that is giving you the error.
Like what was the function call you made?
You may have been doing something like
puzzle.dragDrop(someParameter) or similar.

The main problem you have, is you need to target individual pieces of the puzzle, the code you have there will just pick up the whole puzzle & drag it, ie your call to startDrag() will be resolved to this.startDrag() which is a reference to the whole Puzzle instance.

Just call puzzle.dragDrop() from you're mainTimeline(with no parameters), when you want to allow the pieces to be dragged.
I've included a little exercise for you

public function dragDrop():void {
    //buttonMode = true; // hand cursor if you desire...
    addEventListener(MouseEvent.MOUSE_DOWN, drag);
}

private function drag(event:MouseEvent):void {
    var pieceMousedDownOn:Sprite = Sprite(event.target);
    // homework
    // hmmmm... some pieces are behind others when I drag...
    // what could I "add" here to fix it???
    pieceMousedDownOn.startDrag();
    stage.addEventListener(MouseEvent.MOUSE_UP, drop);
}

private function drop(event:MouseEvent):void {
    stopDrag();
    stage.removeEventListener(MouseEvent.MOUSE_UP, drop);
}

Yay me, I got one. Well I hope it's right, it works.

Now i'm on to try to figure out how to make the piece dropped snap into the place of the piece its over top of, and have the two pieces swap places. I am hopeful.

addChild(pieceMousedDownOn);
