    A GSAP tale: One goofy guy’s odyssey from knowing nothing to knowing just enough to confuse himself. (This is crazy long so feel free to jump to the epic conclusion). Greetings fellow GreenSockers. The end of this week marks the one-year anniversary of my first post on the forum so I thought I’d take the opportunity to share my 12-month story and hopefully encourage others to jump into the conversations around here. Maybe you’ll recognize yourself in some of the things I’ve experienced. My quick history in a nutshell Web design and coding is a second career for me. After 15 years of owning and operating a photography studio and processing lab (back in the film days - yup - I’m old), the digital camera came along and changed that industry, which necessitated a new career for me. I shifted to video production, which led to motion graphics and finally to web design. Our little agency now offers all those services. The web design clients never needed anything fancy so JavaScript took a back seat to HTML & CSS only sites for a number of years. JavaScript & GSAP: false starts and other obligations I first discovered GSAP a few years ago, but only tried it briefly. It looked cool, but with the time obligations of field video work and motion graphics jobs, it wasn’t something I could work into the schedule. Besides that, it was JavaScript – too complicated I thought. I knew JavaScript was the third piece of a good web designer’s skillset along with HTML and CSS, but I always convinced myself that I didn’t have the time and the sites we built didn’t need it. JavaScript Books + Classes = Fail I did make a few attempts at reading some JavaScript books and working through some online tutorials, but it just never ‘stuck’. Maybe the examples were too theoretical and dry or they were the wrong books and classes. I really don’t know, but I abandoned the learning process a number of times. Cut and Paste mentality Why did I really need to learn anyway? You can just Google what you need, cut and paste some code and presto – you’ve got some working JavaScript or jQuery. I only understood a small portion of what I was cutting and pasting, but hey… it worked so the problem was solved. That’s how I operated for quite some time. What’s a loop? What’s an array? What’s an object? Who cares? Wait a minute. This is ridiculous. Last spring, I was remodeling our company website and I had all these grand visions about making things move and behave in certain ways. Googling for code just wasn’t cutting it. I suddenly felt stupid. “This is ridiculous!” I thought. I should be able to learn how to write my own code. Oh yeah, I remembered that GreenSock thing I had looked at a few times and abandoned. That might work. Maybe I could actually learn how to use it this time. I become a forum lurker I started lurking in the shadows of the forum. After reading a lot of posts, I saw people asking many types of questions from simple to crazy complicated (at least to me). Two things I noticed were that every effort was made to find an answer (no matter the difficulty level of the question) and not one post was condescending or snarky. That’s quite rare on the ol’ interwebs, isn’t it? Hmmmm…maybe I’m in the right place. Oh boy… time to ask a question of my own One of the great things about learning GSAP is you’ll also pick up a lot of other JavaScript and/or jQuery along the way. I kept reading and practicing with some simple tweens, but now I had a question. Dare I post? I suppose, like many others, I feared looking like an idiot even though the forum members and moderators seemed quite nice and helpful. I do several dumb things every day so you’d think I’d be used to it by now. Oh well, here goes. My first question had to do with the indexOf() a Draggable snap array. Within 30 minutes, Diaco and Rodrigo had posted great answers and neither one called me stupid! Yay – how cool. I get hooked on GSAP and the forum About that same time, I decided our company should discontinue on-site video production and switch to studio only filming. I got tired of lugging loads of video gear in and out of buildings – it’s quite tiring and as I mentioned earlier – I’m old. This freed up some time and I decided to dedicate that time to learning GSAP and maybe, one day, even helping others. It wasn’t too long and I actually knew the answer to a forum question. I posted some information and wow – a little red indicator lit up on my control panel. Someone liked something I wrote. How fun – I’m hooked. Carl makes direct contact I continued to learn and experiment. I posted a few additional questions of my own, but I tried to answer more than I asked. If someone posted a question for which I had no answer, I tried to look it up in the docs and figure it out. Most of the time I was far too slow and Jack, Carl or one of the mods would already have the answer posted before I was done reading the question, but it was an interesting way to learn. I did sneak in a few good answers, which led to a private message from Carl. He thanked me for participating and helping in the forums. I thought it was pretty cool that a super smart guy like Professor Schooff would take the time to do that for little ol’ me. My decision to dedicate time to the platform and forum was reinforced. Blake and I have a conversation I don’t recall if it was a back and forth in a forum post or a private message conversation, but Blake told me something that, of course is obvious, but it stuck with me and is important for all of us to remember. He mentioned that we all enter this learning process knowing nothing. If someone of Blake’s considerable skill level can be humble enough to remember first starting out in code, there may be hope for me after all. I guess if you think about it, there was a time when the simple concept of a variable was brand new to all of us. We’re not born with these abilities. They’re learned and we’re all at different points on the educational path. Never feel stupid for not knowing something. Moderator Promotion Throughout the last year, I’ve continued to learn and study both GSAP and JavaScript. Some of those books I abandoned in the past even make sense now. I’ve tried to be active in the GS community and answer as many forum questions as possible. If I’ve answered a question of yours, I hope you found it somewhat helpful. I’ve cranked out some fun CodePens and finally started a Twitter account to tweet them out. I am nowhere near an expert with GSAP or JavaScript, but I know so much more than I knew a year ago. Apparently I know enough to be entrusted with a forum promotion to Moderator status. I’m honored to be included on such an amazing team. 12 months down – what’s next? My agency duties are still numerous so I can’t dedicate full time to coding, but it remains something to which I’m committed and thoroughly enjoy. I started this 12-month GSAP journey just wanting the ability to write my own code rather than cutting and pasting the work of others. I’m confident I have achieved that, but I still have days when a simple piece of code just won’t coalesce in my brain and that can be frustrating. I guess we all have those days, right? I make several mistakes every day, but that’s o.k. too. I learn a lot more from my screw-ups than I ever do when it all goes right on the first try. I plan to keep learning and getting better and when I get stuck, I’ll be able to get an answer from this amazing community. I’ll continue to give back to the GS community by answering any questions that are within my abilities to do so. The super mods: Jonathan, Blake, Diaco and Rodrigo Thank you to my fellow moderators. You guys rock and have taught me so much. @Jonathan – if there is a browser bug, quirk or special fix that you are not aware of, I’ve yet to read about it. Your knowledge has helped me fix many pieces of code before they even became a problem. Plus, if I ever have a question of top/left vs. x/y, I know who I’ll ask. @Blake – if I could be half as good at coding as you, I’d be a very happy guy. Your work always teaches and inspires me. I don’t think you’re allowed to ever stop posting on the forum or we may all show up on your doorstep and ask questions. @Diaco – your code is always so concise. I deconstruct some of your pens and am astounded by how much you squeeze out of a few lines. If I made some of your pens from scratch, I’d have 20 variables, 5 loops, 12 tweens and 80 lines of code. You do the same with two variables and 4 lines of code. Amazing stuff. @Rodrigo – when searching the forum, I often land on one of your past posts and learn a lot. Your knowledge is vast and I wish you had more time to post around here. Your ninja skills are incredibly strong. Our superhero leaders @Carl – I’ve participated in several online forums ranging from graphic design to 3D to video production, but the GreenSock forum is the best and a big part of that is you. You not only provide great answers, but you do it in clever ways with just the right amount of humor thrown in here and there. The collection of videos you’ve made is invaluable and should be mandatory viewing for anyone interested in GSAP. I’ve seen you monitoring the forums at all hours of the day and even on weekends. When you get any sleep I’ll never know, but I thank you for your dedication and sharing your knowledge. @Jack – how you had the vision to start GreenSock and write the first version of the animation platform I can only imagine. I’m glad you did because GSAP is such an amazing collection of tools. The friendliness of the community is definitely following your lead. I don’t understand a lot of what you talk about sometimes, but I know enough to be amazed by your brilliance and talent. You call yourself just a guy who geeks out about code, but you’re more than that. You’re a smart and generous innovator who’s created a special brand and place on the web. I think I can safely speak for the community when I say we all appreciate the time and effort you put into helping us make beautiful and high-performance animations. Thank you sir. The epic conclusion. Well… maybe just a regular conclusion. If you didn’t read the whole post, I don’t blame you. It’s ridiculously long and I’m just some guy you don’t know so I’ll wrap it up with this bit of advice. Whether you’re a genius or feel like an idiot, it doesn’t matter. Try to learn one new thing each day and before you know it, a year will have passed and all those little bits will add up to new skills and abilities. If you’ve never posted on the forum, please jump in and participate. The more voices we have around here, the more we all benefit. If you need an answer, please don’t be afraid to ask a question. Believe me, I’m just some goofy guy in front of a computer. If I can learn this stuff, so can you. As I begin my second year in GreenSockLand, I’m looking forward to learning more, seeing everyone’s work and answering as many of your questions as I can. This is an amazing community and I encourage anyone reading this to set up an account and get involved. My best to all of my fellow GreenSockers. See you around the forums. - Craig (PointC) PS I made a little CodePen to commemorate my one-year forum anniversary. It’s how I felt before and after discovering the power of GSAP. Enjoy.

    You can't animate most flexbox values because they're words, e.g. flex-start, space-around, column-reverse. You can't say, animate to column reverse. The browser has to do the layout. But that's actually a good thing as that's one less thing you have to calculate. To do a flexbox animations, start off by recording the position of your element in it's current state. Now change its flexbox style and let the browser reposition it. Now record the new position of your element. You now know where the element was, and where its supposed to be. Now move your element back to it's old position and animate it to it's new position. This all takes place in between animation frames, so you won't see the jump. This technique will work for every flexbox property. It will actually work for any type of layout that the browser handles, like the new CSS grid. For more information, check out these threads.

    There is this big, big tree. Uuuuh, that's high. I always wanted to climb it. Can I? First touch. The peeling is thick, and itchy, but warm and inspiring confidence. I lay my arms around it, starting to rub up. Hmm? Aaha– Okay– That's how– Nice! It's working. That's all I wanted. No need to leave this robust stem. But wait. What's that? There's a branch! And another? I'm curious– The more I climb this tree –body pressed tight onto it– the fear of these little branches slowly fades. I finally, gently step on one. Sometimes they crackle, but never break! My tight grip loosens up; Cheeks stop scratching as I lift my head– Oh boy! So many branches. And look how high I am! Wait what? There's a bird! And anoter one? I start talking to the birds. More birds. I felt like a king just walking the branches. The birds taught me how to jump on them! And soon I'll fly. Soon. I have never experienced anything similar. Such an easy entrance, .. well .. once you accept the word Tween as a thingy describing an animation One can work with GSAP without knowing anything more but .to, .set, and .from. Easy to learn, hard to master. You decide how far you go. When you are part of this special breed of developers/designers, be careful! Because GSAP will suck you in, won't let loose and change the way you see and work the web. That's what I love most. Thank you guys for that. 4 hour research until 1:30am in my freetime, and still burning so much inside that I had to write this. That's how awesome GSAP is.

    I got sliiiightly carried away and made this, haha. I don't if it will help because I saw @Rodrigo and @PointC had provided great answers so I didn't bother commenting the code, but feel free to ask if anything is intriguing. PointC, thanks! hehe

    Hi and welcome to the GreenSock forums!! A looooooooong time ago I made this for another question in the forums. It uses the draggable tool to move the numbers but you could easily use it to get started with what you need: I made a fork of it and changed a bit to simulate what you need: Hopefully this helps. Happy Tweening!!!

    Nice job @Sahil! A while back I was toying with the idea of releasing a tool that'd make this sort of thing easier but I put it on the backburner for a while. I called it "BendyBox" - it basically lets you convert any DIV or RECT into an object thats bendable in various ways. It swaps in an SVG to create those effects and you can register various animation effects that you easily call later, like "drop", "spin", etc. Advanced demo: Basic (with quasi-documentation in comments): Again, not sure if we'll make it an official GreenSock tool yet, but I figured this is a good place to share about it. Feedback is welcome.

    Hi alessio, Just use transformOrigin. TweenMax.fromTo('.test', 0.6, {scale: 1}, {scale: 1.1, repeat: -1, repeatDelay:0, yoyo: true, transformOrigin: 'center center'});

    That's because when a tween is defined it is rendered immediately to the start position, usually only noticed in the case of 'from tweens'. Because you are using set at the start of timeline, it is behaving same. You can set immediateRender to false on first tween and it will behave as expected. Well and you can use just fromTo tween to same thing. // To tween tl.set(".slide", { opacity: 1, immediateRender: false }); tl.to(".slide", 1, { x: 300, opacity: 0 }); // fromTo tween tl.fromTo(".slide", 1, { opacity: 1, immediateRender: false }, { x: 300, opacity: 0 });

    Hello dear friends, No doubt Christmas is coming ... Hi @Jonathan - sorry, when I saw your new portrait, I just felt the need to redecorate my tree to dedicate it to the GreenSock community. I coded my first Christmas tree inspired by the work of Petr Tichy (here) Dec 2015. It was one of my first exercises. Kind regards Mikel

    Hi, For last few days I wanted to start making few video tutorials, I got this idea when I was responding to a thread where somebody wanted to recreate simple carousel effect. This is my first tutorial ever, I plan to make more tutorials mostly based on questions that I answer here. If you feel like you can learn from me, feel free to request any tutorials. I will try to do it depending on the topic and if I can solve it myself. Most of my tutorials will be for those who are just getting started with GSAP. Following is the very first tutorial I made today.

    I've made a few games using GSAP: Nevergrind - Single-Player RPG Firmament Wars - Realtime Multiplayer Strategy Game I have no regrets using GSAP. It's my favorite tool and as far as I'm concerned it hasn't limited me in any way and I feel very productive with it. I plan to make a 3rd game, a multiplayer co-operative rogue-like follow-up to Nevergrind. Developing games with GSAP is a pure joy. If needed you can even pause the game, as long as you don't use setTimeout or setInterval. As long as every timer and animation is created using GSAP (TweenMax, TimelineMax, TweenMax.delayedCall), you can just do TweenMax.pauseAll() to pause the game (this can be done in Nevergrind by hitting ESC). Since GSAP can tween any object value using any ease, it's simple to Tween using the set method, onUpdate, over time, or whatever kind of animating you need to do. Hope that helps. Discovering GSAP was like finding the holy grail for me because I was seriously using JQuery's .animate before that.

    Hi @menschies ! Welcome to the forums! Always remember: With Great Powers, Comes Great Responsibilities. Use them wisely, use them to make things a little bit nicer. A few comments: You can use images instead of inlining the whole SVG if you are not changing the inside of it. The solution to your question is about nesting the separating the elements and nesting them based on your needs. I'm super busy these days but I wouldn't mind lending a hand whenever possible for your landing page - within limits. I can't take any responsibility at the moment.

    So you can imagine, it's Saturday night and there's another deadline looming on Monday. I'm just about to settle in to what I reckon is about 2 hours of work animating "a magical trail randomly jumping around the screen". I got some ideas so just need to crack on. Before I do I just check the "ease-visualizer" and low and behold I find "rough", which I'd forgotten about. Give it a go and that's kinda what I needed, 20 mins later I have finished the job. This keeps happening Jack you have thought of everything and now I don't have any work to do so can enjoy my Saturday evening. So inconsiderate, I mean there's nothing good on TV!! Realised I bought TweenMax 8 years ago, people thought I was mad spending that much money on a tween engine (for Flash). I've used TweenMax in every project I've worked on since buying it and can't imaging developing without it. So just a quick thanks and I'm off to get a beer.

    Okay, I just re-read your question and I think I understand what you'd like to happen. Since you're a Club member, you have access to CustomBounce and CustomWiggle: https://greensock.com/wiggle-bounce Using that, you could easily wiggle an element and have another element drop from it. Here's a quick demo with a couple basic divs. Hopefully that points you in the right direction. Happy tweening.

    Hi @Valeria Welcome to the forum and thank you for joining Club GreenSock. As @Acccent mentioned, there would be a whole bunch of ways to approach this. Here's my two cent approach for you. I'm not sure if that is even close to what you had in mind, but maybe it will give you some ideas. Happy tweening and welcome aboard. @Acccent - congratulations on your Moderator promotion. Well done!

    It's actually a pretty straight forward series of steps to pull of something like this. Depending on other project requirements, things will vary here and there. But the main idea is to establish a number of planes and to make elements on those planes move at differing rates ... typically, the closer the plane to "you", the faster the elements will move by. Here is a quick CodePen explaining the principles of it.

    Great examples, guys! Here is another approach from @OSUblake using the ModifiersPlugin which isn't necessarily simple, but it is dynamic. Blake's ModifiersPlugin collection: https://codepen.io/collection/AWxOyk/ more on ModifiersPlugin: https://greensock.com/modifiersPlugin If you're animation is canned, as you say, Shaun's solution should work very well.

    Well, you *can* get the x/y of the tweening element at any time in the tween. Craft your timeline in a paused state ... use .progress() to position the playhead at a specific point after your initial tween is defined. Then retrieve the top/left at that point to use as the values in your second tween. Finally, play the tween from 0.

    An even easier way to do this is to make the stagger value negative .staggerFrom(".box", .8, {y:60}, -0.15)

    How can you disagree with that when you're already experiencing difficulty? That kind of proves my point. Angular1 has nothing in common with the current version besides the name. But what I was trying to get at is that there's a bunch different ways to create and customize CSS for theming, usually with some type of build process. This isn't directly related to CSS styling, and is more for SVG, but look at how easily an animation can be added to an app. There are similar tools for styling components just like that, but I can't remember the names of them right now. A component is more of an architecture or pattern. Web Components and Polymer are where you'll find most of the widget stuff. I'm not a UA developer, so I don't know a lot about the specs, but animating width and height has nothing to do with them. It invalidates the layout, and has to recalculate the size and position of everything and make any necessary adjustments, which can kill your framerate. It's no different than doing a screen resize. This is unlike transforms, which cannot affect other elements or the layout. Nope. I know how that app works, and it doesn't use a library. Go back to that site, disconnect from the internet, and then refresh the page. It should be working offline. The lag you saw was because it was your first time visiting the page, so a service worker was fired up to install some stuff for offline use. Well I didn't coin that term. That was done by Paul Lewis over at Google. I learned a different version, called a Relative Animation, which might be a better description, but nobody knows what that is, so I don't use it anymore. Every animation in GSAP has a start and end value, so there's nothing unusual there. In the Last step is where you would apply or remove any CSS classes/styling. You put the element in it's end state. The Play step really doesn't apply to GSAP as it will automatically play. That's more for people who have to manually start the animation. And this is where you get everything wrong. There's a time difference between screen refreshes, typically around 16.67ms, so you won't see it change visually. The invert step is the most important part, and is what pulls everything together, but you're not seeing the big picture yet because you think it can be done with className tweens. Can you get these two animations working correctly using className tweens? The video should not jump around when you toggle it. It's using the same CSS and layout from the original demo. This should animate between a column and row when you hover over it. And yes, there is a way to animate it. I'll explain more about this in another post.

    So, last night I was listening to Jack's awesome interview with egghead.io (https://itunes.apple.com/us/podcast/egghead-io-instructor-chats/id1308497805#) and he started talking about all the unexpected uses of GSAP, and it got me thinking; what have I used GSAP for? And I realized the range is from pretty typical to not so typical! My line of work is for a few large clients. So I've used GSAP on many projects; some externally facing (marketing sites) ... some for "exclusive" groups (targeted marketing), and many internally facing (for very specific groups ... members and employees). So, for the typical stuff, it's Immersive content UI indicators and helpers UX sauce For the not so typical, it get's pretty varied pretty quick! But the one project that sticks out the most is GSAP as the heart of a frontend delivery system (backed by Drupal) that drives a community cable channel for a gated resort community in GA. The Drupal side allows content managers to create and place 3 types of media; image slideshows, video, and embedded (iframed) HTML. They have control over timings and transitions which map out to GSAP, background audio playlists and ducking (the ducking is tweened with GSAP ), and asset publish/unpublish dates. For the embedded HTML ... they are calling in external sites which are slideshows, but managed by another group for another purpose; a real estate listings slideshow of active properties within the community that is displayed on a large screen in their sales office which is ... you guessed it ... GSAP! It cycles through 280 properties (+/- a few) daily; transitioning in a property image, then a delayed detail and pricing overlay slides over a portion of the image. But back to the cable channel ... every asset and configuration managed on the Drupal side is fed through custom template files that generate all the GSAP Timelines and Tweens. It has been running for years and is rock solid! So, my not so typical uses are cable channel programming (in the sense of delivering programmed content), digital kiosks, and digital signage. So, I'm curious ... what have others used GSAP for that might be a little outside the norm?! Edit: I changed the title from "What have you done with GreenSock?" to "How have you used GreenSock?" Upon reading it back some time later ... it occured to me that the title could be implying that something is wrong with GreenSock Of course there isn't!

    Hi again @determin1st .. #1 We are helping you... #2 GSAP is already popular and does rule forever This isn't a GSAP algorithm thing . GSAP can only use what CSS property values are reported and computed by the browser, based on how you have your HTML and CSS setup. Like i said above this has to do with the CSS Spec on how height is calculated with box-sizing. As well as how the CSS box-model works. That is the nature of CSS, animating padding will affect height of its parent regardless if box-sizing is used or not Animating anything but transforms and opacity will cause jank (lost frames). Transforms and opacity do not cause a repaint and layout to be recalculated on every render tick frame. Transforms are also better for interface object, since they can animate on a sub-pixel level for silky smooth motion. Whereas padding and other non transform and opacity properties can only animate on a pixel level. And non transform or opacity CSS properties cant take advantage of hardware acceleration (the GPU) for smoother animation. You could take advantage of using transform scale instead of padding. We can only offer advise and solutions, but in the end its up to you. Happy Tweening!

    The best thing to do here for any kind of help would be to distill the problem down in a CodePen. We can then fork and recommend things to fix any issues you might encounter. But, at first glance ... the get rid of the initial flash of the SVG, you can simply use some inline CSS to not display it, add "opacity: 0;" (or visibility: hidden;") to its selector in a style sheet, or load it in with JS within $('document').ready. (I'm sure there are other options I'm forgetting right now). Edit: Dang it ... did it again.

    You can use modifiers plugin to calculate values before applying them so your tween will continue playing on resize as if nothing happened. Though if your current tween inside the timeline is not active then you will have to manually set it's position on resize.

    Just to chime in @Visual-Q, some scroll events, depending on how they were trigered, cannot be cancelled. It might be outside GSAP's reach. @GreenSock himself will be able to confirm that. In the meantime, this article has some useful information about how browsers handle scroll. https://blogs.windows.com/msedgedev/2017/03/08/scrolling-on-the-web/#lvzozB8m1fZOWgTt.97

    Trick here is to append a clone of the first .slide to the end of #slider. Animate through for the count of the slides minus 1 (i.e. ignore the last slide ... that is to say, less than totalSlides minus 1 because we address them with a 0 index) so that as the last slide gets into position, the slider starts back from zero resulting in a fairly seamless loop.

    Hi @dgmldr, Please have a look to your CSS .slds-notification { position: relative; width: 20rem; border: 1px solid #ecebea; border-radius: .25rem; box-shadow: 0 2px 3px 0 rgba(0,0,0,.2); transition-duration: .4s; transition-timing-function: ease-in-out; transition-property: margin,max-height,opacity,top; If you try ... .slds-notification { position: relative; width: 20rem; border: 1px solid #ecebea; border-radius: .25rem; box-shadow: 0 2px 3px 0 rgba(0,0,0,.2); /* transition-duration: .4s; */ /* transition-timing-function: ease-in-out; */ /* transition-property: margin,max-height,opacity,top; */ } you will have a clear responsibility for the job - done by GreenSock. Kind regards Mikel

    You, my friend, will need to step into the wonderful and mesmerising world of MATHS. Have a look at this channel by Keith Peters, it will teach you tons about calculating physics-like movement. https://www.youtube.com/user/codingmath

    I'd definitely echo @GreenSock's advice and convert that to a path. I've fought with many circle animations and that is the easiest approach. (You can also convert it to a path before exporting from your vector software if you like.) I started a thread last year about SVG circle fun in the various browsers. It may be of interest to you. Happy tweening.

    Hi and welcome to the GreenSock forums. The way I normally attack this situation is using React's lifecycle methods, most specific the componentDidMount method. With that you know for sure that all the child have been rendered before making the animation. This is a sample that uses a code similar to that. Unfortunately I don't have any samples around with the specific behavior you need but hopefully you'll get the gist of it: Basically when creating each child (which in this case come as a hardcoded array, but getting the data via props shouldn't be much different) you give it a unique ref attribute to each which then you can use to loop and create the timeline or the stagger instance if you like (to create a stagger instance just reach to the array in the props and that should do it), then create the timeline and finally play it. I'll try to whip something during the afternoon that matches what you need. This is another sample but it uses a different approach, since it uses Transition Group since the elements are mounted and unmounted depending on the user interaction. It doesn't use a timeline or stagger, just a simple delay. This relies in the fact that the code is executed very fast (for larger apps you could consider server side rendering or perhaps another approach, once all the elements are rendered, perhaps pagination to render a small chunk of elements) and that the components are rendered in the sequence they exist in the app's data (again hardcoded in an array). But considering the fact that in a real app React will render all those child components at once so we can rely on that delay to create the stagger effect. Pay no attention to the code that's commented out, that's there in case someone needs to use CSS Transitions. The only catch is that the duration const used in the <Transition> component has to be the same that the one used in the GSAP instance, otherwise the component mount/unmount will be out of sync with the animation. https://codesandbox.io/s/7Lp1Q8WBA Hope this helps. Happy Tweening!!!

    Hi @ericshew The most noticeable problem is line 19. //Switch this tl.reversed() ? tl.play() : tl.reversed(); //to this tl.reversed() ? tl.play() : tl.reverse(); That should get everything working for you. It can certainly work with playing and reversing the timelines like that, but you'll see some harsh morph jumps when hovering on/off quickly between <li> tags. You could get some smoother morphs with rapid hovering like this: Just my two cents worth. Hopefully that helps. Happy tweening.

    yPercent is the easiest, but the slowest because it has to calculate more stuff because it's based on the size of the element. And the reason for the translate and matrix transform is so that you can animate yPercent and y separately. TweenLite.to(box, 1, { yPercent: -50, // translate value y: 100 // matrix value }) GSAP has some performance stuff built in. Inspect your middle box (box2). GSAP switches from 3d to 2d at the end. However, if you set force3D to true, it will only use 3d. But really, your best bet is to just test and see what works best for what you're doing. Performance will vary a lot depending on what you're animating, and the browser. Setting will-change: transform in your CSS might provide the best performance for Chrome, but if you try that in Firefox and the element is too big, you might get a warning in your console saying that the surface area is too big, and will-change has been canceled. It's definitely frustrating figuring out what works best for everything.

    Hey Blake, About 30 seconds into your previous post (exaggerated demos of waapi vs gsap) I had pulled out the Ban Hammer and was giving it a nice polish;) Great job debunking the myths of the gurus! I can't help but laugh and cry a little when I hear people say "you should only animate transforms and opacity". Normal person: "I'd like to animate the width of this.." Guru: NOOOOO, STOP! It will cause a repaint! Your site could crash, especially on mobile devices! Normal person: "I just ran an augmented reality demo on my phone where a horde of zombies exploded in front of me" Guru: You don't understand, laying out a grid with different sized fonts is EXTREMELY processor intensive.

    I don't think so. About the only thing a WAAPI timeline has in common with a GSAP timeline is the name. All I can say is that you should give it a test drive. If you like creating CSS animations keyframes, and are familiar with CSS animation terminology and properties, you'll like WAAPI. Now don't get me wrong, I would actually like to see @GreenSock add something like keyframes to GSAP, I've just never asked for it. It would be really helpful for situations that otherwise might require you tween the progress of a timeline with another animation, but I certainly wouldn't want to use keyframes as the basis for all my animations. Weren't you the one that brought up cargo cult programming? As WAAPI becomes more widespread, it's going to be like 2013 all over again. But instead of people saying that CSS animations are better than JS animations, the mantra will be that CSS and WAAPI animations are better than JS animations. Why? Because that's what some performance gurus over at Google said, and they know what they're talking about. And some of the stuff I've read on Twitter and Medium is also pretty convincing. I mean, just look at this comparison. This is what happens when the browser is busy, which apparently happens all the time. The JS animation on the left is all jank, while the WAAPI animation on the right doesn't skip a beat. Amazing! Don't believe me? See for yourself. I spent a lot of time coming up with an algorithm that accurately simulates how a normal site behaves. That demo says all that needs to said. WAAPI is clearly better. No further testing is required. Oh wait... a challenger appears. It's called "Something other than transforms or alpha". Oh how the tables have turned! Turns out that WAAPI is indeed susceptible to jank. Not only that, but the jank can be magnified if the animation gets out of sync, looking like a video game with really bad collision detection, glitching through walls and stuff. So locking the browser up to show how jank affects JavaScript animations is just stupid, and can actually disprove what you're were trying to prove. Besides, if your site really has that much jank, then one or more of the following must be true. You're not a good developer or just starting out. You're scroll jacking the interface. See previous point. You're creating a WordPress site and just discovered themes and plugins. See first point. You're viewing a demo showing how JavaScript animations are affected by jank. You're using IE6 with 40 different custom search bars while running BonziBuddy. So all those demos and articles that talk about the performance benefit of WAAPI are not entirely true. WAAPI only performs better when it's being demonstrated using cherry picked conditions. There are like several hundred different CSS properties that can be animated. To say that you should only animate transforms, alpha, and a couple filters is crazy! That's sounds more like a coding challenge. And what about SVG? Should we just ignore that all together? I think not.

    Hi and welcome to the GreenSock forums, Regardless of what the effect is, the main thing GSAP is going to handle for you is the sequencing of animations. What it boils down to is taking a fullscreen element, introducing a column on the right that is split vertically, and then introducing another column on the right that is split vertically. I would start with trying to do the css layout for the final state: http://prntscr.com/hdrf3p Just try to get a few different colored divs to fill the screen like that. And then use TimelineMax to sequence each element coming in and resizing as necessary. 90% of the challenge is going to be in building the HTML and CSS the right way. I'm guessing the GSAP code is going to literally be 3 or 4 lines for that transition. If you don't know TimelineLite/Max, put this project to the side and experiment with the basics. https://greensock.com/sequence-video https://greensock.com/position-parameter

    Thanks for the illustrations and demo. I had to relearn a technique I illustrated in Flash tutorial 6 years ago http://www.snorkl.tv/2011/08/tile-transitions-for-grid-building-and-masking/ (select diagonal top and click toggle) If you add each box's row number to column number you will get values the increase across the grid in a diagonal. You can use these numbers to generate the offset of each animation in a timeline. In the demo below I put the sum of column and row in each grid. Since you don't want a delay of 36 or 49 seconds we multiply that by 0.03 to shrink it down. Try using (c*r) for a nice curve instead of diagonal

    Results may vary, but <use> elements are not static, so the browser has to track changes across every instance. https://stackoverflow.com/questions/8604999/does-reusing-symbols-improve-svg-performance This slide show reveals really poor performance. http://slides.com/rovolutionary/tuning-svg-performance-in-a-production-app#/ Performance issues aside, the real issue when working with the <use> tag is that everything is hidden inside a shadow-root, which you can't access. That might be ok for static icons, but not for animations.

    Believe it or not, the trick here is the easing! I did something similar to kind of give a "slot machine" rolling aesthetic to the end of a sentence here What you'd want to focus on is the ease: Elastic.easeInOut.config(8, 0) For your case, "8" might be too much ... so modify that to get the right feel for your project.

    Hi @Nineve Use scale instead of zoom. Problem solved. Serializing and deserializing the position and rotation of draggables should be real easy. In that demo, you can loop through the array of draggables like this. draggables.forEach(function(draggable, index) { var target = draggable.target; var transform = target._gsTransform; console.log("Rotation", transform.rotation); console.log("X", transform.x); console.log("Y", transform.y); });

    Hi @RuizBox Welcome to the forum and thank you for joining Club GreenSock. @Sahil is exactly right, drawSVG only works with strokes. The problem you'll encounter with your design is the gradients in the stroke of your logo. There are ways around this and we've had some discussions about animating gradients in strokes, but I think there's a much easier approach for you. If it were me, I'd add a mask over the top of the logo and use drawSVG to animate the mask and reveal the logo. Like this: If you have additional questions, a CodePen demo is the best way to get answers as we can easily edit your code to find a solution for you. Here's some info about that. Hopefully this helps with your project. Happy tweening and welcome aboard.

    Hello! I've been meaning to drop a pen here but it took me forever to find some spare time and then another eternity to conceptualize the bits needed for the animation.

    I guess my question would be "why?". GSAP is great at manipulating element properties over time and managing those timelines. The pen above illustrates something a bit outside of that scope. While I'm sure something could be whipped up with GSAP ... why when the solution in the pen handles it perfectly?

    If you're using an array with the data you'll use as a reference, then there's no need to use an anonymous function in the ref attribute, just pass the property of the element being used in the map helper: const data = [ {id:1, name: 'box1'}, {id:2, name:'box2'} ] data.map( (item, index) => className={styles.box} key={`box${index}`} ref={item.name}; ); Then reference the element following the same pattern: tl.to(this.refs.box1, 0.5, { backgroundColor:"#F19939" }); Keep in mind that the GSAP instance must be created inside the component's that has the node element. Here's a simple example made in codepen. Is not a lot of code so it should be easy to follow: Happy tweening!!

    Hi @madfatter Looks like they're using a SVG with some png graphics for that effect. I'm not sure why they have pngs. I'd probably make the whole thing a SVG. The animation itself is pretty easy. You rotate the entire graphic, but each smaller piece rotates an equal amount in the opposite direction so they stay upright. You could then animate the text opacity at each stop. I made a similar rotation of planets as an answer to another forum question. Maybe it will give you some ideas. If you're just getting started with the JavaScript version of GSAP, I'd recommend: https://greensock.com/jump-start-js https://greensock.com/get-started-js Once you have something started, we'd be happy to assist you with any GSAP related problems or questions. For the best possible answers, please provide a demo with any questions. Here's some info about that: Hopefully this helps. Happy tweening.

    Hi @kvnmcwebn Have you seen these pens by @chrisgannon ? He's creating those speed lines in a loop with the drawSVG plugin. That plugin is a Club GreenSock bonus, but you can experiment with it on CodePen. Here's some more info about the Club. https://greensock.com/club Hopefully that helps a bit. Happy tweening.
