Hey, I'm trying to apply a zoom masking effect where, as I scroll down, the text scales up. But when I scroll back up quickly, the masking doesn't align properly with the scroll speed.

I connected a horizontal scroll that has the full width of its content and scrolls at a different speed. This was followed by several problems: Instead of different speed I'd like to have a certain, it seems to depend on the width of the user screen and Idk how to implement it. When scrolling, background image also moves, I'd like to avoid it. Also, there are friezes, maybe it's because of the background. ( I'm sorry if this is out of the scope I’m not sure I can ask it here ) the width of the yellow line is constantly changing how can I make it fixed ? This code is given below, thanks in advance and I apologize if the question is not provided correctly, please let me know if something is wrong.

Hi, Is there a special / approved way of measuring animation performance on the client? I would like to measure if the animation has lagged vs specified duration, or if greensock was being clever under the hood and skipped frames to optimise the animation. Currently I'm using a onComplete call within gsap.to to print the end of animation time, and comparing that to a time from just before the animation was called. This way I'd be able to turn off animation effects automatically across the site based on some initial test, for slower performance devices. One extreme edge case was when I opened a web app in a virtualised macOS machine that did not have GPU passthrough, so simple transform animations would freeze the entire machine. Would avoid having these problems by running a small transform animation test for a few ms duration to see how it performed, then decide on the animations for rest of site. EDIT: The timestamping method doesn't work well for performance measurement - testing shows the elapsed ms from before gsap.to() to onComplete call could be less than the duration specified in gsap.to(). EDIT2: For anyone having the same experiment with a virtualised machine for dev environment, the guest OS / Safari doesn't freeze or drop frames as per the fps measuring function given by Jack below. It's likely about how VMware renders the graphical output of the guest OS back to you on the host OS that freezes / drop frames.

Hi I have to develop this animation where an image starts from scale:0 and opacity:0 then grows rotating with an easing power2.out then keeps it rotating infinite by linear easing. Some ideas? Thanks

We are building a quite long storyboard which consists of about 12 scenes. Basically, you scroll down the page and things happen: SVG animations, curtain div's coming down and up, pinned screens etc. We have a LOT of TimelineMax functions and we are starting to experience some performance issues, most likely because all the animations are still running even when not on the screen. Is there a way to stop/start functions to optimise performance? If you guys have any advice / links, please let me know.

Hey, When animating an unknown number of elements like so: var timeline = new TimelineMax({repeat:-1}), items = document.querySelectorAll('.item'), startDuration = 20; for(var i = 0; i < items.length; i++) { var myDelay = (i * 0.5); animate(items[i], myDelay); } function animate(item, delay) { var a = TweenMax.to(item, startDuration, { rotationZ:'360', ease:Linear.easeNone, repeat:-1 }); timeline.add(a, delay); } What is the best way to modify the duration/speed of an individual tween? Thanks

I will update this original post with the latest info as everyone shares their approach/technique: GreenSock Community, I just wanted to reach out and see what others are doing to help the animation speed/repaint/performance... I am pretty new to all this so I'm not sure what the best approach is... also as I search for solutions, sometimes, I find that I am starting to follow something that is not considered the best/latest approach. Here are some of the links I am currently looking at for information: See Below: If you have any other good reads/tutorials/ approaches I could learn from it would be much appreciated.

You can defer your animation by calling a function using setTimeout or requestAnimationFrame. Notice how this logs out B then A. http://codepen.io/os...40?editors=0011

Hello everyone! I am only getting to grips with GSAP and I use it for relatively simple animations and effects. I was working on this website (see the opening heading)- http://www.adbmedical.com Everything works very smoothly on my local machine but on the server there is a delay and the animation plays very choppy. Can anyone tell me how to solve this problem? Many thanks in advance!

Hello, I need wheel spinning like below video. could you please guide me /Ganapathi

I am reading Google Material animation guidelines. https://www.google.com/design/spec/animation/authentic-motion.html#authentic-motion-mass-weight Has anyone able to mimic as close as possible to it? Does anyone has a set of easing values I can plug and play? Cheers, Venn.

Hello, at the moment I have a div that rotates infinite with normal css animations. But I want to do it with Greensock, because i want the animation to be more responsive depending on what I click. The idea is that I want the div to start rotating after clicking a button. It start slow and builds up speed. After 1 Second it's on full speed and keeps rotating until I press the button again. Then it should decrease the rotation till it stops. Could somebody point me in a direction? I would prefer to use tweenLite if that is possible.

Hi everyone, first of all, this is my first day using gsap and I am like a child ! Awesome plugin. Aaand I just Edit it because it was a really stupid question when you search a little more. I am very sorry. At least this is my first post in this forum.

Hi, For the purpose of distilling this problem to its principal components, let's say I have 2 object that are side by side, say at y=100 pixels. I want both of those to fall down the screen, but to different destination y locations. I want them both to accelerate (easeIn), at the same speed, even though their distance to tween is different. Also I want to cap their final velocity, so they never fall faster than pixels/sec. Here is an illustration: (initial position) Sprite1 Sprite2 (fromX = 0, fromY = 0) (fromX = 100, fromY = 0) (toX = 0, toY = 200) (toX = 100, toY = 400) (falling --> Sprite 1 and Sprite 2 have the EXACT same Y location as falling, since they are using the same custom easing IN function to control their acceleration and final velocity) (falling) .. .. .. Sprite1 has stopped here) Sprite1 (x=0, y=200) Sprite2 (is at the exact same Y locations because they are following the same easing IN function, regardless of total distance to travel (Sprite2 continues to fall until it reaches it target location of y=400) Sprite2 (x = 100, y = 400) Thanks, --Kestal

Hi! (nice new site btw) I've got a nice quick animation, that works well on desktop (and on my phone), but on an ipad2 it's too quick. Ie it happens before the ipad has chance to render the frames. It's kind of a gratuitous animation, so it'd be nice (but not essential) if it could be seen. So odd request maybe, but is there a way to make a tween slow down for a slower processor? Thanks, Andy

Is there any speed or Garbage Collection difference between TweenMax & TweenLite ? Actually currently i'm working on site in which i'm using more than 500 tween with TweenMax , and site works perfectly in firefox but in chrome and safari tween lag very badly. link of my demo page

How can I test the performance of the visitor's device on page load? So that if it does <20 FPS I can skip animations altogether I didn't find anything like this in the documentation
