  1. Hi! I am trying to transform or build this css animation into a GSAP timeline because with CSS is consuming too much CPU. The #bar-- is a g element of an svg that contains 80 bars @for $i from 80 through 1 { #wave-g__top--#{80 - $i} { animation-name: barOpacity; animation-iteration-count: infinite; animation-duration: 5s; animation-delay: $i * 0.065 + 0.25s; } } @keyframes barOpacity { from { opacity: 1; } to { opacity: 0.2; } } This is animation I am getting with CSS https://i.gyazo.com/fec064c25c2456ce2c3e34e932a5607e.mp4 and I thought this could be the similar in GSAP but is just not working, I am very new with this actually. const bars = document.querySelectorAll('#wave-g__top g') let tl = new TimelineMax({ repeat: -1 }) bars.forEach((b, index) => { const delay = index * 0.065 + 0.25 tl.to(b, 0.1, { opacity: 0.2 }, `-=${delay}`) })
  2. With CSS 3 I am able to use keyframes, which makes animating objects really flexible. For example, with keyframes I can change a object opacity from 0 to 1 at 50% of the animation and then back to 0 at 100% of the animation... that creates a smooth fadein and fadeout. I am trying to accomplish the same with gsap. With TweenMax I can set a fromTo... but how, would I go about doing a fromTofrom? I tried doing something like this: var mydiv = new TimelineMax() .add(TweenMax.fromTo($(".mydiv"), 1, {opacity:0, scale:0}, {opacity:1, scale:1})) .add(TweenMax.fromTo($(".mydiv"), 1, {opacity:1, scale:1}, {opacity:0, scale:2})); However, when using "add", there's a very small delay between the first and the second add. How do I go about removing that delay? Or, is there another way of doing chained animations?
  3. I am looking for capturing objects position from canvas. Here is an example http://cssanimate.com/ Is it possible to update object position from canvas to code?
  4. Hi there! I'm new in the GSAP world but already loving it! Today, I'm trying to replicate a loader animation that I found on loader.io. The problem is that it provides either a CSS animation or an animated (SMIL) SVG (which is bound to be obsolete). That's why I tried, in order to be better at tweening, to replicate the effect using the base SVG minus the animations. The effect I'm looking for is a seamless loop: when the first ripple is a 50% of the animation, the second one should start and when the second one is at 50%, the first one should start again... You get the idea I tried with two timelines but my brain can't seem to process the delays and duration needed to achieve the effect, let alone the easings... Thanks in advance to anyone willing to assist a noob in understanding the intricacies of the GSAP world
  5. I'm a newbie to Web Development and in the process of learning if GSAP can fill my animation needs. I am pretty sure it can. This is my second post. In my first post, I mention I am currently taking an E-course and I am in the middle of creating a javascript reaction tester application: http://codepen.io/KerryRuddock/pen/rLJPkq To view the codepen correctly, please change the View to Full Page. Click Start. A random sized and colored ball rotates around the screen based on a set of CSS keyframes: twirl This codepen is HTML, CSS and JS only, no GSAP just yet. The code is a collection of tests in CSS and Javascript. Not all of the code is used within my application, I am experimenting. Apologies for any code read-ability issues. I need to know if I can do the following with GSAP and perhaps a hint in the direction to go in. In this topic, I use the word 'tweened' to cover any object that is the middle of animation, transition, transform, keyframes, and any other time/movement speciality that I may have missed.. 1) I will be changing the reaction tester animation to GSAP I hope the switching over goes smooth. My goal is to have a 'tweened' object collision detection checking in real-time. The collision may be against a border or perhaps another 'tweened' object. I need to perform real-time interval checks of the shapes x,y position of the object during a 'tween'. Can I do this? On a mouse-event, ie. object.click(), I need to kill any tween any progress. Can I do this? On a collision-event, I need to either be-able to either a) kill 1 or more tweens and start new tweens, or modify the existing tween that is currently running. Am I able to do either a or b or both? Thanks for your time, Looking forward to your feedback.
  6. Hello everyone, I am new to GSAP and I need your help to convert a CSS keyframe animation in a javascript one with GSAP. @keyframes elliptical-anim { 0% { transform: translate3d(0,150%, 0) rotate3d(0, 0, 1,0deg) translate3d(0,-150%, 0) rotate3d(0, 0, 1,0deg) scale3d(.1,.1,1); } 20% { transform: translate3d(0,150%, 0) rotate3d(0, 0, 1,-72deg) translate3d(0,-150%, 0) rotate3d(0, 0, 1,72deg) scale3d(1,1,1); } 96% { transform: translate3d(0,150%, 0) rotate3d(0, 0, 1,-359deg) translate3d(0,-150%, 0) rotate3d(0, 0, 1,359deg) scale3d(1,1,1); } 100% { transform: translate3d(0,150%, 0) rotate3d(0, 0, 1,-359deg) translate3d(0,-150%, 0) rotate3d(0, 0, 1,359deg) scale3d(.3,.3,1); } } I'm using the 3D version of the animations in order to force the hardware acceleration. Thanks in advance for your help !
