Applauz Posted April 4, 2014 Share Posted April 4, 2014 I'm trying to set top and bottom limits on a scrolling / tweening movie clip and can't quite get it to work. Here is my current code. Any help would be appreciated. var destY:Number = activity_mc.y; function handleMouseWheel(e:MouseEvent):void { trace(activity_mc.y); trace(e.delta); var _delta:int = e.delta > 0 ? 1 : -1; destY += _delta * 200; TweenMax.to(activity_mc, .2, {y:destY}); } Link to comment Share on other sites More sharing options...
Carl Posted April 4, 2014 Share Posted April 4, 2014 Sorry, its difficult to trouble shoot partial code fragments like that. For one I don't see where you are using addEventListener to register that function to respond to MouseEvent.MOUSE_WHEEL. Also, I'd suggest trying to make it work without the tween, just try to find the proper y value first. something like this should work import com.greensock.*; import flash.events.MouseEvent; function handleMouseWheel(event:MouseEvent):void { var newY = mc.y + (event.delta * 3) //keeps y value of mc between 0 and 300 newY = constrain(newY, 0, 300); TweenLite.to(mc, 1, {y:newY}); trace(mc.y); trace(event.delta); } function constrain(num:Number, min:Number = 0, max:Number = 1):Number { if (num < min) return min; if (num > max) return max; return num; } stage.addEventListener(MouseEvent.MOUSE_WHEEL, handleMouseWheel); Link to comment Share on other sites More sharing options...
