    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.

    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.

    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!!!

    I think I see what the problem is - GSAP doesn't natively interpolate "vw" or "vh" units (though it likely will when 2.0.0 is released, but that won't be for a few months most likely). It can set() them directly, but interpolating is different. In this case, the inbetween values are converted to px. So here's a solution that gives you the same result but just does the conversion for you at the right time: Is that what you're after?

    Hi @kaliel Since you're not animating anything that would require an element to be redrawn, converting this over to PixiJS would be pretty easy. You're SVG could be used like a sprite sheet, which is good. 1 graphic is much better than 400+ graphics. I can show how to do that later, but you'll be able to animate 10,000 objects without skipping a beat. Press down to add more bees. That's running without using a particle container, which would make it even faster.

    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.

    So what is the edit at the bottom about? What kind of solutions are they looking at, or possibly thinking about? Right now I'm just not seeing a lot of value in WAAPI from an animator's perspective. The performance is nice, but it's not a game changer. And there will be other ways to improve GSAP performance in the future. Have you looked at Houdini? The cornerstone of Houdini is the CSS Typed Object Model. It's CSS with types e.g. number, length, matrix, keyword, color. The current CSS object model is string-based. To animate the DOM, the browser and GSAP have to spend a lot of time parsing, converting, and building string values, which is dumb. A matrix should not be a string. With Typed OM, that process will be mostly eliminated. .box { height: 30%; } // What's the height? console.log(getComputedStyle(box).getPropertyValue("height")); // "259.5px" console.log(getComputedStyleMap(box).get("height")); // CSSUnitValue {value: 30, unit: "percent", type: "percent"} That can provide a HUGE performance boost. I don't remember what talk I heard this from, but somebody benchmarked animating transforms on 1000 elements using rAF. They found that the browser was spending about two-thirds of the frame budget just parsing the transform strings. When benchmarked using Typed OM, the parsing time was virtually eliminated. The goal of Houdini is to make looking at caniuse.com a thing of the past. You will no longer need to wait around for a browser to implement a feature. Just copy and paste the raw code that makes it tick! One part of that raw code might be paint worklets using the Custom CSS Painting API. It allows you to draw stuff directly to an element's background, border, content, mask, etc. Paint worklets run in a separate thread, so it could be used to improve performance. I was looking at how GSAP could be leveraged inside a separate thread, but some changes would need to be made to the library. A worklet has no access to the window or document, and there are no timing mechanisms like requestAnimationFrame or setTimeout. An animation would have to be manually stepped setting something like a time or progress value. And a paint worklet is stateless, so you can't save/store values. You can create instances of stuff, but the painting has to behave almost like a pure function. One reason for that is because the browser can create the same worklet multiple times, and will kill them as it sees fit. Another reason is the same paint worklet can be called multiple times for different properties or different elements. I know that sounds like using GSAP would be pointless, but it could still be leveraged. On the DOM side, GSAP can tween something like a progress or time value, and in the worklet we can take that value, and plug it into a tween or timeline to interpolate values on some objects. We can then use those values to paint stuff on the element. It's works just like a canvas animation. Here's a demo that animates Google's logo. Yeah, I copied most of it, but look at the paint code. It's calling an interpolate function everywhere. That could obviously be replaced with a tween or timeline. Even better, using the MorphSVG plugin with canvas Path2D objects which can draw SVG paths. On the DOM side, I'm using GSAP to tween a simple --scale property, which is what drives the morphing animation. Well, there's also a --total-time property, but that is being updated by a rAF call. It's used to animate the balls up and down when the --scale is at 0. Note that in order to view this demo, you must use Chrome or Opera, and enable the Experimental Web Platform feature. You can always disable it afterwards if having it enabled scares you. You can copy and paste this into your address/search bar to jump directly to the flag. about://flags/#enable-experimental-web-platform-features And once you have that flag set, be sure to check out some of the Houdini demos here. https://lab.iamvdo.me/houdini/ripple Houdini is still evolving, so there's lots of room to make suggestions and get something incorporated into the spec. Getting the WAAPI spec to change will much harder as that's more mature. Houdini does have a draft for an animation worklet, but right now it seems to be geared towards doing scrolling animations with WAAPI. I would much rather have a general purpose JavaScript animation worklet that doesn't depend on WAAPI or DOM elements.

    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

    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.

    In that case, more people will be willing to help you if you provide your code. Just post new question and attach codepen with your current code so we can help you out or guide in right direction.

    Hi @alan0buchanan It really depends on where you look. On this forum, and places like CodePen, you're not gong to find a lot of people using ES6. Look around a place like HTML5 Game Devs, and it's a completely different story. I think most people start using ES6 because of some library/framework they are using. If a person is using React, there's a good chance they are also using ES6 because it's used in all the examples. But I've noticed that a lot of people still live in a jQuery world. The only code they are exposed to is what they see in jQuery's documentation and 10 year old answers on Stackoverflow. So I would have to say that the reason you don't see a lot of ES6 is just plain ignorance. A lot of people have never heard of it, or are misinformed. You'd be surprised by how many times people have asked me how to convert Babel into JavaScript. If you want to see more ES6 examples, people need to be informed, so help spread the word. What is ES6? It's the 6th version of JavaScript, and is also known as ECMAScript 2015. ES5 was the previous version, and came out in 2009. Why should I use it? Because it's JavaScript. There's a lot of new features that can help you write code that is cleaner, smaller, and more concise e.g. arrow functions, string templates, destructuring assignment, computed property names, classes. What is Babel? It's a tool to convert modern JavaScript (ES6) into code that can be used in older browsers. What about performance? There are some new features that haven't been optimized by browsers yet or need a polyfill. This will of course change over time, but if something is too slow, don't use that feature. Most of the features are syntactic sugar, so there should be no difference in performance.
