Beginner needs help with tweens

programming flash
1

Hello, I’m having issues with this simple program I made. There’s two rectangles, a holder and a dragger. When you click the dragger, you can drag it until you mouse_up and it will return back to the position of the holder via tweens. It works fine, if you give enough time for the tween to fully take action and let it return to its proper place, but if you reclick it before it’s finished, the dragger gets stuck and misaligned. Here’s the code I have so far, thank you so much! :bounce:

        public var twnMoveY:Tween;
        
        public function script( )
        {
            mcRectangleHolder.graphics.lineStyle( 1 );
            mcRectangleHolder.graphics.beginFill( 0x0000FF );
            mcRectangleHolder.graphics.drawRect( 100, 100, 150, 100 );
            mcRectangleHolder.graphics.endFill( );

            twnMoveX = new Tween( mcRectangleDragger, "x", Strong.easeOut, mcRectangleDragger.x, mcRectangleHolder.x, 1.0, true );
            twnMoveY = new Tween( mcRectangleDragger, "y", Strong.easeOut, mcRectangleDragger.y, mcRectangleHolder.y, 1.0, true );
            
            twnMoveX.addEventListener( TweenEvent.MOTION_STOP, tweenStop_handler );
        }
