Greetings,

I have a TweenMax that is has x initialized to 1332px. It's a simple animation from left to right along a 1332px long div.

var tl2 = TweenMax.to(document.getElementById('point'), 1.5, {
	//x:0,
	y: 0,
	//repeat: 1,
	//onRepeat: playSound,
	yoyo: true,
	repeatDelay: 0,
	ease: Power0.easeNone,
	paused: true
});

x gets set dynamically based on width of screen.

 

At some point i'm rotating the div within which it runs by about 20 degrees so it can run from bottom left to upper right corner.

To do than I'm trying to 1424px (just for the sake of argument, that's what I'm getting on one particular laptop):

var pwa = $('.pointWorkArea');
pwa.css({
'width' : someCrossLengthInPX /* change the width of div where animation runs */
})
.css({
'transform' : 'rotate(' + eyeBaller.settings.crossAngle + 'deg)'

}).css({'left' : -pwa.position().left});

tl2.updateTo({ x : someCrossLengthInPX });



... however, I'm not seeing the change in DISTANCE the animation runs at. It rotates fine, but keeps running at the old side to side distance and not corner to corner.

Any ideas?

Done, it was easier than I thought it would be :-)

So the update i'm struggling with is on line 165 of the JS part of the pen.

 

Use case would go like this:

1 - click the START button

2 - once the ball is running, click the far right square ( showing a diaagonal line from top left to bottom line corner ) of 'Profile' section

Now the trajectory will rotate a few  degrees.

 

The issue is most apparent when the pen is running in full screen mode.

Hi tomekpilot

 

UpdateTo isn't working because x is a CSS-Plugin value. Don't worry, I got confused by what it does when I first started using GSAP.

 

So what you need to do is to create another tween with your new x value. I updated your profile2 function showing how to do this while putting everything inside a new timeline.
