  1. Hi, do you have any tips how make a dragger/timeline or progress bar fulfill by itself as the mouse is being moved? Additionally, how to read its value in real time? I want to update mood.progress() value adequately. In short words - the goal is for pet's mood to get better as you move your mouse. Right now you can do it by dragging a dot on a slider. I'm using GSAP since yesterday. I've been fighting all day with it and cannot think of any proper solution. Thanks! [EDIT] Solved
  2. Hey legends! Thanks for all the amazing work y'all do. Absolutely loving the GSAP journey. I have the following challenge: - I'm trying to create a form that always opens on page 1. - Once open, the user can then click back and forth between the pages - If they close the form from page 2 and then reopen, it opens on page 1 again. - The page section animation has a matchmedia associated with it as well (thanks to Blake!) I've got reduced test case, which almost works. I've built 2 timelines (1 to open the form and 1 to switch pages). The problem lies somewhere in my approach/logic. After closing the form from page 2 and reopening it, it successfully opens on page 1, because I’m using onComplete tl.seek(0).reverse(). HOWEVER, once reopened, the click event to swap pages does not work on the first click and requires the user to click "next" again to switch pages. My goal is to get it to swap pages on the first click. Hopefully that makes sense. Any help on how to approach/fix this would be greatly appreciated Much respect
  3. So, in the Codepen we have a fairly simple animation. On click of the button, we animate the <header> and <nav> elements in, and click it again, we animate them out. It's a toggle button. However, on mobile, we don't want to run the animation but instead want things to appear instantly. We have achieved this using calls to progress(0) or progress(1), however, we've noticed that if you first toggle the animation on desktop, and then go to mobile, and toggle it again, that without the calls to tl.reversed(false) or tl.reversed(true), the animation still tries to animate and doesn't work correctly. Does anybody have any ideas why adding those lines would make it work as I would expect it? What am I missing? To reproduce: On desktop, or anything matching the media query in the Pen (1000px), click the 'Play animation' button, then click it again to hide the animation. Reduce your screen size down to trigger the mobile code, and again, toggle the 'Play animation' button. Note: the code in the Codepen works, you'll need to remove calls to tl.reversed() on lines 18 and 21 to see the issue. Any help would be much appreciated!
  4. Hey Greensock Would be great to have the progress() function return 0-1 normalized with the selected easing. I just animated the rotation of car wheels, and needed that rotation to match the easing of the tween of the car's movement. Ended up using my own method, by fetching one of the tweened properties ( (current_value-start_value)/(end_value-start_value) ), but a generic progressWithEasing(), or another property to the progress() method, like 'normalize with easing' or something would be great... Cheers.
  5. Hey yall, I'm new to greensock, and I love the library and this forum. This forum has especially been helpful as I practice and learn gsap technique. I have a new project that is supposed to animate a background SVG, and it has the following requirements: The background diagonals are supposed to slowly move downwards, kind of like a parallax effect. It's a big SVG with lines running across it When the user scrolls, it supposed to speed up the parallax progress a little bit with some easing, but continues to progress down the timeline When the user scrolls upwards, its supposed to reverse the tween timeline I've been able to achieve a few things, but the things i'm still having trouble with are Reversing the scroll direction with the scroll event is upwards. Also right now, I have the progress of the scroll animation tied to the height percent of the `window.innerHeight`. but after testing, i don't think this is a good idea. Because the window height percent is not compatible with the progress of the timeline. So i should find another way to progress the timeline.. but i'm not sure what. For reference I used this post to get started, which as been really helpful: If anyone has advice from doing something similar to this, please please let me know. My knowledge is not advanced enough to debug. Thank you Thank you!! PS please excuse the messy code, i'm just trying to get this thing working. Best, Gabriel
  6. Checkout the codepen. If you use the buttons to set timeline progress(), you can go back and forth between 0 and 0.5 no problem, but as soon as you go to 1, you can't get back to 0. I've experimented with other values as well, and everything seems to work until you go to 1 for the first time. After that, when you try and return to 0 it reevaluates to 1. Does this look like a bug, or do I have my logic wrong? Thanks!
  7. this is my first attempt using GSAP (it seemed to be the best animation library I could find). I'm trying to create a simple slot machine. Here is a codepen with the minimal amount of code. http://codepen.io/dax006/pen/LGoNrE It does 3 things. After creating a random symbol, it 1) creates a 'constantly spinning' tween and saves it 2) creates a 'slowing' tween and saves it 3) resets the progress of each tween/symbol to be 1/4th down the screen. Bug/problem #1 - Tweens are playing yet NOWHERE do I play() the tween. The tweens are PAUSED by default. Even if they are not paused, I IMMEDIATELY pause() them in resetslot(). Problem #2 - Progress() does not seem to be setting all symbols accurately (you can immediately see that the top symbol is askew) Problem #3 - Setting a tweens progress() to zero triggers its onComplete (watch the console) Problem #4 - Setting a tweens progress to 1 triggers its onComplete even though I have SuppressEvents:true (watch the console) I'm very frustrated with GSAP at the moment . Any help is appreciated -John Edit:problem 5 can't pause the codepen demo so can't read console
  8. Greetings everyone! Thank you for taking the time to read my question. I am using TweenLite and TimelineLite to create an animation timeline that simulates a user navigating a set of "sections". When the user clicks a button, I create a tween that animates a percent value over the course of 0.3 seconds. On "update" of this tween, the "progress" of my timeline is set using TimelineLite.progress(x). My issue is that if one of the sections is tweened for another reason to a different position on screen, when the timeline is progressed, the section immediately snaps back to where the timeline wants it, based on the original creation. What I would like is that the position of the section would tween from it's new, updated position, to the endpoint defined in the timeline. Is this possible? Here is some pseudo-code that should help illustrate my question. var percentObj = { current: 0 }; var myTimeline = new TimelineLite(); // ---------- // Set starting positions myTimeline.add( TweenLite.set($('#section1'), { 'css': { 'y': 0 } }), TweenLite.set($('#section2'), { 'css': { 'y': 1000 } }), TweenLite.set($('#section3'), { 'css': { 'y': 1000 } }) ); // ---------- // Now that starting values are set, // pause the timeline myTimeline.pause(); // ---------- // Create future animations that // will be triggered by the user // Animate to section2 myTimeline.add( TweenLite.to($('#section2', 1, { 'css': { 'y': 0 }, 'ease': 'Power1.easeInOut' }) ); // Animate to section3 myTimeline.add( TweenLite.to($('#section3', 1, { 'css': { 'y': 0 }, 'ease': 'Power1.easeInOut' }) ); // ==================== function buttonClick() { TweenLite.to(percentObj, 0.3, { 'current': 0.5, 'onUpdate': updateProgress } } function updateProgress() { myTimeline.progress(percentObj.current); }
