  1. Hi, Not sure how many questions get asked about flash these days but I have one. I have having issues on scrolling using the code below. It works but but its slow. I am thinking a "blitmask" would work great here but I don't know where I would put it. Can you give me some tips? Thanks -Ed /// SCROLL BAR /////////////////////// public function throwIt(clipContent:MovieClip) { // old code //var bounds:Rectangle = new Rectangle(_screenX - clipContent.width,0,_screenX,_screenY); // custom var var bounds:Rectangle = new Rectangle(0,0,_screenX,_screenY); //var mc:Sprite = meow.getChildByName("content") as MovieClip; var mc:Sprite = clipContent as MovieClip; addChild(mc); //some variables for tracking the velocity of mc var t1:uint,t2:uint,y1:Number,y2:Number; mc.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler); function mouseDownHandler(event:MouseEvent):void { TweenLite.killTweensOf(mc); y1 = y2 = mc.y; t1 = t2 = getTimer(); mc.startDrag(false, new Rectangle(bounds.x, -99999, 0, 99999999)); mc.addEventListener(Event.ENTER_FRAME, enterFrameHandler); mc.stage.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler); } function enterFrameHandler(event:Event):void { //track velocity using the last 2 frames for more accuracy y2 = y1; t2 = t1; y1 = mc.y; t1 = getTimer(); } function mouseUpHandler(event:MouseEvent):void { mc.stopDrag(); mc.stage.removeEventListener(MouseEvent.MOUSE_UP, mouseUpHandler); mc.removeEventListener(Event.ENTER_FRAME, enterFrameHandler); var time:Number = (getTimer() - t2) / 1000; var yVelocity:Number = (mc.y - y2) / time; var yOverlap:Number = Math.max(0,mc.height - bounds.height); ThrowPropsPlugin.to(mc, {ease:Strong.easeOut, throwProps:{y:{velocity:yVelocity, max:bounds.top , min:bounds.top - yOverlap - (littleLogo.height + littleLogo.height/3) , resistance:777}}}, 33, 0.25, .3); } } ////////////////// /// end SCROLL/////////////
