pause(); on sertain "y" position when reverse();

Hi there!

Is it possible somehow to stop tween timeline on ceratin "y" or "x" position when you reversing timeline?

Of course, I'm tweening position of object.

Well, sort of. Keep in mind that when a value tweens, it could hit ANY number inbetween the start and end values during the tween. Like tweening 0 to 100 may not hit exactly 50 - it may hit 49.5878 and then 50.55478, etc. I suppose you could sense when it crosses a certain value (although it sounds like you might want to re-engineer your code a bit - this is a very odd requirement)

 

Just use an onUpdate. Kinda like:

 

var prevX:Number = mc.x;
var stopAtX:Number = 100; //or whatever
var myTimeline:TimelineLite = new TimelineLite({onUpdate:checkPosition});
myTimeline.append( new TweenLite(mc, 3, {x:500}) );

function checkPosition():void {
   if (myTimeline.reversed && (mc.x > prevX && mc.x = stopAtX)) {
       myTimeline.pause();
   }
   prevX = mc.x;
}

 

(you could use the onUpdate only in your tweens that affect "x" if you prefer)

Thanks for advice. I also was thinking about re-engineering my code

I already tried your code suggestion, but since I need to stop at particular position it's not works well...

So, I going to try solve my problem other way.

 

Thanks again!
