    Tween around circle

    This demo here is from one of my lessons. It uses one of the technique's @GreenSock suggested. I create a circleHolder (red line) and put a circle inside it to the right. I then rotate the circleHolder and counter-rotate the child circle (using negative rotation of the parent). https://codepen.io/snorkltv/pen/MWopvBX?editors=0010 You could edit the css of course to hide the red lines. From there we build this nice ferris wheel https://codepen.io/snorkltv/pen/qBRwvgp For easy responsiveness, @Cassie is correct, SVG would be the way to go!
  2. Just chucking a fun bonus here to bring a few more eyes to this fantastic deal. Last week I came across this tweet from @kenneyNL showing this interesting contraption that "controlled" an animation. I became instantly enamored with the playful animation. The synchronization with the "inputs" was so perfectly executed that I had to wonder if the device was real. I also loved the fact that the artwork was so incredibly simplistic (low detail) but conveyed so much emotion and life. With all those great attributes it was just screaming at me to be rebuilt using SVG and GSAP. I knew the rotations, color changes, face-reveal stuff would be dead-simple to animate and choreograph with GSAP, but I was very intrigued with the scattering of the little circles. Attempting the "random" scatter I needed random positioning and sizing of the circles around bob (my name for the character) but not behind him. There was no point generating circles that I couldn't see nor did I want to have 90% of circles bunched together off to one side. I decided I needed a "sort-of-circular" distribution of circles around bob. I'm an "avoid confusing math and trigonometry" at all costs type of programmer so I took an approach where I generated a bunch of circles with offset x positions and then used that offset in the transformOrigin and applied a rotation. The approach came this demo from one of my lessons that uses basic <div> elements. https://codepen.io/snorkltv/pen/Bapqwmy Once I got the basic layout I needed to add some randomness and needed something that was easy to revise and test so I came up with a click-driven approach so I could rapidly test my code Click anywhere to generate the scatter https://codepen.io/snorkltv/pen/4804b10ff391109de2d70517bf9913a3 I was happy enough with the results so I re-wired the function to return a timeline that I could easily nest in my main animation sequence. Within no time I had things spinning around, changing colors and scattering circles. Finished Sequence https://codepen.io/snorkltv/pen/LYLRqPy My approach of using offsets in a transformOrigin and then applying rotation works fine with DOM elements, but SVG is a bit of a pain. As you move and transform elements their transformOrigins need adjusting. Although I kind of got it how I wanted it, the code was a bit confusing and I knew I would have a tough time explaining it if I ever used this for a lesson. After messing with "the wrong and easy way" for a few hours failing to get the exact results I wanted I bit the bullet and pasted in some trig code and found it much easier to tweak to my liking. The scatter function basically has a loop that will: initially determine evenly spaced angles then offset that angle 5 to 15 degrees in a positive or negative direction then set the circle at that angle using a random radius within a certain range then scale them so that only a few are big The end result is that there's about 3 circles in each quadrant that aren't too close to each other. After the circles are all positioned an animation is added to a timeline that shrinks them and moves them randomly. Time break-down for complete project 1hr artwork prep 2hr scatter experiments 0.5 hours building out initial sequence 2hr additional tweaking and testing 0.5 convert scatter to trig-based approached 1hr more tweaking of everything Although I have to admit it did take more time than I initially thought, I had so much fun along the way. GreenSock's timelines make it so easy to get the exact choreography I wanted. GSDevTools was invaluable when it comes to testing each part. I love scrubbing slowly to see exactly how things are positioned and how they animate. Being that I'm always focusing on new lessons for my students every week it's rare that I animate something like this just for fun. I'd encourage you to find some fun small animation in the wild and try to replicate it. It's a fantastic way to learn and keep yourself fresh. If you have absolutely no idea how to build a javascript animation sequence like this check out my courses and my special deal above. My training is specifically designed to guide you through the best parts of the GSAP API and help you build fun stuff like this. Lastly, big thanks to KenneyNL for the inspiration. Check out his twitter profile and give him a follow. He creates loads of free game assets that look amazing.
  3. Hi @PG1 Building a robust timeline visualizer would be quite an undertaking. I created a video to explain how the getChildren() method can be used to grab animations from a timeline, get their start times and durations, and then use that info to build a rudimentary visualization Once you start throwing in staggers, nested timelines, and tweens that target multiple elements things get complicated fast. This video is just meant to introduce you to some of the basic concepts.
  4. That’s a really cool effect. it looks like you are using a super old version of GSAP though. In GSAP 3 eases are functions as explained in the video below. No more getRatio()
  5. My video on Locomotive Scroll and GSAP has helped quite a few people get up and running My course ScrollTrigger Express addresses many common issues that come up in these forums and I've been going into responsive, scrolldriven animations as well as doing some helpful demo destructions. Although I do very comprehensive explanations of ScrollTrigger's core features, I wouldn't claim for it to be an "advanced" course. Id say 80% of the cool ScrollTrigger effects have more to do with having a solid understanding of building the effects with GSAP than controlling them with ScrollTrigger. But it seems you have a good handle of that stuff. I also tend to stay away from "performance" topics as there are so many variables that there is rarely a silver-bullet solution. FWIW ScrollTrigger internally has loads of optimizations to deliver amazing resuls. Also, I'm 100% confident that the next release of GSAP will have some very cool ScrollTrigger features that you will appreciate, but I'm not at liberty to discuss them. trust me
  6. You will want create a loop so you can create animations and ScrollTriggers for each header. A basic demo is available in this thread

  9. Here's a bonus demo for you from my course ScrollTrigger Express Once you build your ScrollTriggers for each element in the loop, you can target child elements using querySelector() This demo might help if you want to animate multiple items in each blog post section. https://codepen.io/snorkltv/pen/b0b8e9c4a880b97379630f2ab9561407
  10. hi and welcome to the GreenSock forums, The demo below is from one of my courses. Feel free to study and borrow what you need. The basics idea is that 2 tweens are created using the same duration. One of them has an onComplete that passes the target into a function that creates a new set of tweens. https://codepen.io/snorkltv/pen/jOrKwwX
  11. my advice would be to create 1 timeline that does the full circle animation. tween the progress of that timeline to any value you want below the progressTl shows the syntax for tweening the progress of the circle's timeline (tl). you can create tweens any way you want and pass them the progress from the data attributes or whatever. https://codepen.io/snorkltv/pen/mdmYVEL?editors=1010 hopefully this points you in a direction that works for you. also, if you just need to animate the stroke of a circle, it would be much easier using DrawSVG:
  12. just to add another option to the list. with yoyoEase you can optionally have a different ease on the repeat. I think the elastic is a bit aggressive https://codepen.io/snorkltv/pen/bGWZqRN
  13. Welcome to the forums Thanks for the demo. You were pretty close. The biggest thing to fix is that you need to find the title and text in each section. Notice how I use querySelector on each section in the the loop https://codepen.io/snorkltv/pen/BaRMGNV?editors=1010 My course ScrollTrigger Express has a video explaining exactly how to approach this type of project. Here is a demo I use to teach this approach https://codepen.io/snorkltv/pen/b0b8e9c4a880b97379630f2ab9561407 Learn more about ScrollTrigger Express
  14. gsap.to(graph, { duration: 2.5, ease: CustomEase.create("custom", "M0,0 C0.46,0 0.496,0.014 0.616,0.088 0.734,0.161 0.884,0.4 1,1 "), y: -500 }) i just copied the entire tween code with custom ease and it comes in as one line (mac chrome). FWIW in all my years of using the ease visualizer I've never seen those line breaks.
  15. That's a great pro-tip from @PointC. Also, check out this video to learn the setting in the stagger object which supports staggering from "end" and "center" and "edges" https://codepen.io/snorkltv/pen/BajxopX Check out my Free Course: GSAP 3 Express for my tips like this.
