Co-ordinates of sprites drawn from mouse appear 0.

Question

Sorry for the confusing title.
I asked this question few weeks back - http://forums.adobe.com/thread/1106063?tstart=0
Using Ned's code, I was able to add the drawn lines during runtime, to the sprites, which were being added to the array "lines"
public class Main_Game extends MovieClip
                    private var drawing:Boolean;
                    var line_mc:Sprite;
                    public static var lines:Array = new Array();
                    public function Main_Game()
                    drawing = false;//to start with
                    stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);
                    stage.addEventListener(MouseEvent.MOUSE_MOVE, draw);
                    stage.addEventListener(MouseEvent.MOUSE_UP, stopDrawing);
                    public function startDrawing(event:MouseEvent):void
                     line_mc = new Sprite();
                        addChild(line_mc);
               lines.push(line_mc);
                     line_mc.graphics.lineStyle(9,0x000000);
                    //move to the correct starting position for drawing
                     line_mc.graphics.moveTo( mouseX, mouseY);
                    drawing = true;
                    public function draw(event:MouseEvent)
                    if(drawing)
                              line_mc.graphics.lineTo(mouseX,mouseY);
                    public function stopDrawing(event:MouseEvent)
                    drawing = false;
Now, I need these lines, to follow a collision detection. For that I need the sprites co-ordinates. When it was not working, I tried doing a trace on the sprite co-ordinates in a for-loop as lines[i].x, but it always showed 0.
Any help with this, please?

Answer 1

all your sprites are at 0,0.
use:
public class Main_Game extends MovieClip
                    var line_mc:Sprite;
                    public static var lines:Array = new Array();
                    public function Main_Game()
                    stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);
                    stage.addEventListener(MouseEvent.MOUSE_UP, stopDrawing);
                    public function startDrawing(event:MouseEvent):void
      stage.addEventListener(MouseEvent.MOUSE_MOVE, draw);
                     line_mc = new Sprite();
line_mc.x=mouseX;
line_mc.y=mouseY;
                        addChild(line_mc);
               lines.push(line_mc);
                     line_mc.graphics.lineStyle(9,0x000000);
                    //move to the correct starting position for drawing
                     line_mc.graphics.moveTo( 0, 0);
                    public function draw(event:MouseEvent)
                              line_mc.graphics.lineTo(mouseX-line_mc.x,mouseY-line_mc.y);
                    public function stopDrawing(event:MouseEvent)
                         stage.removeEventListener(MouseEvent.MOUSE_MOVE, draw);
