  1. I am trying to get a div to rotate on drag using the Draggable api in a fresh create-react-appinstallation. I cannot seem to get it to rotate. Here is my App.js file: import React, { Component } from 'react'; import { Draggable } from 'gsap/all' class App extends Component { componentDidMount() { Draggable.create('.draggable', { type: 'rotation', onPress: function() { console.log('clicked'); }, }); } render() { return ( <div> <h2>React & GSAP Draggable</h2> <div className='draggable'>Drag and rotate me</div> </div> ); } } export default App; When I press the div, I can see the clicked log to console, but the div stays put when dragging. TweenMax works fine: TweenMax.to(target, 3, { color: 'red', })
  2. Hey there, I am trying to import the `ThrowProps` plugin from the bonus zip. In my file I need the plugin, I am importing this: import Draggable from 'gsap/Draggable' import '../assets/throwProps' then further down: componentDidMount() { const rotationSnap = 360 / 14 Draggable.create('#wheel', { type: 'rotation', throwProps: true, snap: (endValue) => Math.round(endValue / rotationSnap) * rotationSnap }) } The wheel turns on drag, but there is not snap or inertia. Running this just like this I get the following error in terminal: Failed to compile../src/assets/throwProps.js Line 13: 'define' is not defined no-undef After adding `/* eslint-disable */` to the top of the plugin to stop it from complaining, I get this error: Failed to compile../src/assets/throwProps.js Module not found: Can't resolve '../TweenLite.min.js' in '.../src/assets' I then added this line at the top: import TweenLite from 'gsap/all' and changed require("../TweenLite.min.js") to require(TweenLite) After all this, the warning I get is this one: Compiled with warnings../src/assets/throwProps.js .250:54-72 Critical dependency: the request of a dependency is an expression Anyway, nowhere during this process did I manage to get the wheel to turn with inertia. I am fully aware I am either missing something or doing something wrong, but can't figure out what it is. Help ?
  3. Hi, I'm trying to use scrollTo in React. But I can't make the increment value to works with scrollTo... Here is the function that not working: handleClick = () => { let incrementNumber = 500 TweenMax.to('content', 0.5, { scrollTo: { x:'+='+incrementNumber } }); } Here is the function that can works if I just use a fixed number, but like this I can make the scrollTo increase 500px every time I click it: handleClick = () => { TweenMax.to('content', 0.5, { scrollTo: { x:500} }); }
  4. I am trying to use GSAP with React. In React I am creating a component with some text animations, for which I would I would like to create several instances at runtime. The main component should look like this: import React, { Component } from 'react'; import './App.css'; import { TimelineMax, Bounce} from 'gsap'; import Title from './Title.js'; let mainTimeline; class App extends Component { componentDidMount() { setTimeout(this.animate, 1000); } componentWillUnmount() { mainTimeline.kill(); } animate = () => { mainTimeline = new TimelineMax({ id: 'Everything' }); const titleTimeLine = new TimelineMax({ id: 'Title' }); const titleTimeLine2 = new TimelineMax({ id: 'Title2' }); mainTimeline.addLabel('start'); // get external timelines titleTimeLine.add(this.title.timelineEnter); titleTimeLine2.add(this.title2.timelineEnter) mainTimeline .add(titleTimeLine, 'start') .addLabel("title2") .add(titleTimeLine2, 'title2') } render() { return ( <div className="App"> <Title text="The benefits are:" clipPathId="clipPath1" ref={(el) => { this.title = el; }}/> <Title text="This should work" clipPathId="clipPath2" ref={(el) => { this.title2 = el; }}/> </div> ); } } export default App; And the Tile component is: import React, { Component } from 'react'; import { TimelineMax, Power4, SlowMo} from 'gsap'; import './Title.css' class Title extends Component { constructor(props) { super(props); const { text, clipPathId } = this.props; } get timelineEnter() { const tl = new TimelineMax(); const duration = 1; tl.to(this.line, duration, {attr:{x1:120, x2:880}, ease:Power4.easeInOut}) .to([this.reveal, this.line], duration, {y:"+=120", ease:Power4.easeInOut}) .to(this.line, duration, {attr:{x1:500, x2:500}, ease:Power4.easeInOut}) .to(this.clipPathReveal, duration, {y: -180, scale: .3, transformOrigin:"50% 50%", ease:SlowMo.ease.config(0.7, 0.7, false)}) return tl; } render() { return ( <svg className="demo" viewBox="0 0 1000 500"> <defs> <clipPath id={this.props.clipPathId} ref={(el) => { this.theClipPath = el; }}> <rect ref={(el) => { this.reveal = el; }} x="0" y="-100" width="1000" height="250" fill="#000" /> </clipPath> </defs> <line ref={(el) => { this.line = el; }} x1="500" y1="150" x2="500" y2="150" strokeWidth="20" stroke="red"/> <g ref={(el) => { this.clipPathReveal = el; }} clipPath="url(#clipPath1)"> <text transform="translate(500 250)" fill="#3088Ef" textAnchor="middle" fontSize="80">{this.props.text}</text> </g> </svg> ); } } export default Title; The problem is that in the code: <g ref={(el) => { this.clipPathReveal = el; }} clipPath="url(#clipPath1)"> <text transform="translate(500 250)" fill="#3088Ef" textAnchor="middle" fontSize="80">{this.props.text}</text> </g> for the clipPath attribute, I need to pass a dynamic URL. Otherwise, it doesn't work correctly. Is there a way to pass a dynamic id to the URL in clipPath="url(#clipPath1)". Something like clipPath="url({dynamicURL})" or something? In the first instance of <Title>, it should produce clipPath="url(#clipPath1)", while in the second it should be clipPath="url(#clipPath2)" and so on.
  5. 0down votefavorite I am pretty new to GSAP and like using it so far, however, I have a question on how to do some relatively simple animations with react.js involved. I have two divs and an arrow in the middle. What I want is when a div is clicked the arrow will animate and move under the div that is clicked. And if the other div is clicked then the arrow will move under that div. I feel like this is easily done with HTML/CSS but incorporating it into react has been difficult. Any help is greatly appreciated coming from a entry-level coder.
  6. I am trying to set up some concentric circles that are draggable/rotatable, and I'm trying to set it up on <g> tags because there are going to be some smaller SVGs that need to rotate around as if they were attached to the large color bands. I read the pinned SVG gotchas thread, and although it doesn't mention <g> tags, it's clear that it should work because it works here: Some notes about my codesandbox demo: I had some issues trying to use TweenLite by including gsap as a dependency and using a regular import, so I commented out the imports and added CDN links to TweenMax and Draggable in index.html. Clearly Draggable is loaded and works because I also made an extra draggable div just to make sure. The ultimate behavior I am looking to get is that the concentric bands should be rotating infinitely. If a user clicks on one of the bands, the rotation stops and the band becomes draggable. Once the user clicks on a different band, the rotation starts up again. There are two sections of code that are commented out right now, but if you uncomment them you will see the rotation animation/pausing behavior working. The part that's eluding me is the draggability. All the important stuff is happening in the BaseBand.jsx file. Any pointers on how to get draggable rotation working on an SVG <g> tag would be very welcome.
  7. I am experimenting with these title animations https://github.com/bigfanjs/react-titles and I want to sequence some titles. The questions that I have are: How can I pause or play the original animations? How can I sequence the animations (for each title)? - For example, play the first one, wait for .7 seconds and play the second one, etc. How can I set the initial position of each title? My code is: Here is the code I have: import React, { Component, Fragment } from "react"; import styled from "styled-components"; import * as titles from "react-titles"; import { TimelineMax, Power3 } from "gsap"; const mytitles = [ { component: "Title2", title: "This is ", subTitle: "Sweet", isOpen: false, size: 100, x: '50' }, { component: "Title6", title: "Let' see", subTitle: "if this works", isOpen: false, size: 400, x: '400' }, ] class Title extends Component { constructor(){ super(); this.renderTitle = this.renderTitle.bind(this); this.restartHandler = this.restartHandler.bind(this); this.tl = new TimelineMax({paused: true}); } state = { isOpen: false } restartHandler(){ const {tl} = this; tl.reversed( !tl.reversed() ); } componentDidMount(){ const {tl} = this; mytitles.forEach( (e,i) => { //tl.set(this.refs[e.component], {left:e.x, top:e.x}) tl.to( this.refs[e.component], 1, {x: e.size, y: e.size/3 , scale: 0.5, opacity: 0.5}, .5 * i ); }); tl.reverse(); } getComponent(e) { const ATitle = titles[e.component]; //ATitle.handleRest(); //const {t1} = this; //this.tl.set(this.refs[e.component], {left:e.x, top:e.x}) return( <div className="box" key={e.component} ref={e.component} > <ATitle size={e.size} text1={e.title} text2={e.subTitle} open="false" style={{ position: "absolute", x: " +e.x+" , y: " +e.x+", "fill": "orange" }} onComplete={this.handleComplete} /> </div> ) } renderTitle(e,i){ return( this.getComponent(e) ); } handleComplete = (status) => { /*const {selected, component} = this.state; if (!status && selected !== component) { this.setState({ component: selected, isOpen: true }); }*/ } render() { return( <div> <button onClick={this.restartHandler}>Toggle Tween</button> <div> {mytitles.map(this.renderTitle)} </div> </div> ) } } export default Title;
  8. Recently was trying to replicate the above codepen in a react component with gsap and the animation completely fails, it doesn't even start or trigger. Can someone help me look for bugs? The codesandbox link is here : https://codesandbox.io/s/402ov4lyr7 Please Help.
  9. I'm hovering on a div with mousover/mouseout handlers. hoveron/hoveroff runs just fine... but.. hovering back on... forces it to stick so that hoverOff is never triggered. I feel like I've seen this before, but I can't tell where. I'd really appreciate any help on this. Many thanks in advance! Sincerely, Beau link to video handleMenuHoverOn(arg) { const {tl, refs } = this; BtnDB.btns.forEach((btn, idx) => { tl.to( refs[`dot-${btn.id}`], 0.15, { x: btn.hoverPos }, '-=0' ); tl.to( refs[`text-${btn.id}`], 0.5, { opacity: 1 }, '-=.5' ) }); } handleMenuHoverOff(arg) { const { tl, refs } = this; BtnDB.btns.forEach((btn, idx) => { tl.to( refs[`dot-${btn.id}`], 1, { x: 0 }, '1' ); tl.to( refs[`text-${btn.id}`], 0.5, { opacity: 0 }, '-=.5' ); });
  10. Hi folks, i moved my first steps in the Green Sock world and i find it amazing Thanks a lot for all the goodies. I'm trying to develop a card game in react and i've read a lot of resources in the forum to know how match React+GSAP and i think i get it (in particular i love this) I don't really have a GSAP related question, it's more an abstract question on how to correctly implement the whole flow of my app because i'm getting stuck in the animation part. I posted the question in stack overflow HERE but i would love to hear some impressions by the forum experts because typically they give wonderful hints If you feel this post does not belong to this forum feel free to delete it, thanks anyway.
  11. Hello GSAP community, I am trying to play 2 timelines one after the other. when timeline 1 finishes, immediately play timeline 2. After lots of trying and reading the forum, I still haven't found a solution yet. My problem is when I get some panels open and I click on the menu button, I want the open panels to slide back then immediately animating all the panel to go offscreen So far I need to click twice on the menu button for this to happen I am using a master timeline, as i understand is the way to do such things. what do I do wrong in the master timeline? why are the timelines not chaining? Sorry the code is a bit messy but I’ll work on refactoring soon, however, any tips will be welcome Thanks a lot
  12. Hello everyone. I have been trying to use MorphSVGPlugin for the last 24 hours and I don't fine my way out. I'm writing a react App, using rekit which is based on create-react-app. It includes Babel, Webpack 3 for bundling, React hot loader for hot module replacement and so on. So following other threads from this forum, I installed gsap by npm and then copied the membership plugins for npm users into node_modules/gsap, and then I can write import { TweenLite, TweenMax, MorphSVGPlugin } from 'gsap' ... TweenMax.to("#start", 0.5, {morphSVG:"#end"}) When I try to use it I get "invalid morphSVG tween value: #end" From what I've read it means MorphSVGPlugin is actually not added. To confirm I tried: console.log(TweenLite) console.log(TweenMax) console.log(MorphSVGPlugin) An only the last one shows undefined The problem I think it's that MorphSVGPlugin is marked as unused and not added to bundle.js. As I'm not familiar with the bundling process, I've trying to Google how to change the webpack config file or forcing the compiler to add it, but no luck so far. I hosted it in https://s3.amazonaws.com/gsap-forum/index.html just for reference, but I think it's not necessary. Can you please help? Thanks in advance. build.js package.json
  13. Hi, I have a React component that is a replica of the Reddit character. It is composed of several grouped paths and I would like to conditionally render a different face on the character based on the value of this.state.face in the component and tween the animation when the faces change. In the codepen example, I have two alternative groups of paths: base_face and angry_face. I use a ternary operator to click and show each version, but I can't figure out how to tween a group of paths to animate from base_face to angry_face and vice versa. Any help would be greatly appreciated. Thanks, Paul
  14. I have a GSAP animation working in a React component on codepen (thank you @rodrigo). Now I am trying to use it in my React project, but I get an error message saying, "'../../index' does not contain an export named 'TweenMax'." I'm guessing my strategy of placing the cdn links for TweenMax and MorphSVGPlugin in the public/index.html was not the correct way to add GSAP to the project. Do I have to download the source code and place it in the project or can I still use the CDN - and if so, where do I place the link? Thanks for any suggestions. Paul
  15. Hi guys, I'm new to React and using GSAP with it. I'm trying to do something really simple. I'm calling an animation on componentDidMount() and now I would like for this animation to leave as well. Now, I though I could do it using componentDidUnmount(), but that is not working. Can anyone help animating something out? Code: componentDidMount(){ this.loadOverlay = TweenLite.to(this.loaderOverlay, 1, { width: "110%", zIndex: "900", ease: Expo.easeInOut, delay: 2.1 }); } componentWillUnmount(){ this.loadOverlay = TweenLite.to(this.loaderOverlay, 1, { width: "0", right: "0", left: "initial", ease: Expo.easeInOut, delay: 4 }); } Thanks!
  16. Hi GSAP community, Let me start out by saying that I'm very new to React, but I'm looking to do a smooth animation on page load using GSAP. I've done several animations before using GSAP, but when it comes to React, animation just seem really complex. Right now, all I'm looking to do, is having my loading screen, slide of to the right using Expo.easeInOut after a couple of seconds, revealing the page beneath it. But all documentation about animating in React seems extremely complex, compared to what usually takes 2-3 lines of code to do. Can anyone of you help? Thanks!
  17. Hello, i have this problem with react and splitText... I have replace all the files in the gsap/node_modules from my 'bonus-files-for-npm-users' and import like this : import {TweenMax, Sine, SplitText, ease, Back} from 'gsap'; How can i fix it ? thanks Yves
  18. Hi Everyone, I'm trying to figure out how to use timelineLite with React properly. I attached a codepen that works but I have read is not best practice. The key thing I need is a parent component that will contain the timeline object as a state and then a series of child components that I iterate over. I read this blog post that claims that it is important to use the onComplete() call back when I am setting up my timeline entries. The callback gets triggered within the ChildItem when it appears or disappears. The problem with react is that data flows from the top on down, so I can't for the life of me figure out how I can get the callback up into the parent component so I can register it properly. Can anyone suggest the best way to handle this particular problem? Are there any other changes I should make to this codepen? I heard that I should be using refs instead of ReactDOM but I haven't been able to figure that out either. Thanks!
  19. Hi all, I started working on an idea and want to stop before I go further and ask a few questions and get some criticism on best practices. I'll preface with saying that I'm only concerned with modern browsers. First, GSAP performance. Is there a better approach I could take to accomplish the same thing and would perform better? Second, React with GSAP. This should probably be a separate question... I've been building react apps via `create-react-app` for a while and in the past, I had some issues using GSAP in React. Mostly, with using plugins that `require TweenLite`, requiring me to eject the `create-react-app` and customize the webpack config to resolve the alias. (As an aside, I now get around ejecting for simple things like this by using react-app-rewired). There are some edge case issues in particular I'm trying to solve. When you move the mouse quickly from left to right, sometime the cube will spin too much. I've played around with some boolean checks to see if I'm overlapping tweens or something but nothing seems to help. I suspect it's based on the way I'm "snapping" the cube's most forward face to the center when the mouse moves back to the center. EDIT 1... is it possible that this is related to React state? I wonder if react-gsap-enhancer would help. EDIT 2... looks like the codepen may even have other issues that aren't present in my local setup. If you move the mouse too far past the cube it stops, which should only occur when the mouse is over the cube. And it's more difficult to see the real issue I'm trying to solve in the codepen.
  20. Hi everyone! This is my first time using GSAP, and as a learning experience, I'm trying to create a clone of the Twitter heart animation, seen here. I've came to a stumbling block, however, when it comes to step 6 on the above link (the hollowed-out circle). My initial plan was to simply create an SVG with a transparent fill-colour and then animate the width of the circle, but stroke-widths aren't animatable in GSAP (and it appears anywhere), so does anyone have any suggestions of how to create this step? The centre of the circle needs to be transparent, so the "hacks" that have came to mind so far won't suffice. For example, creating two circles, with a smaller white one on top of a larger one to fake the hollowed-out centre (if that makes sense?). That won't work because the SVG will need to be transparent to fit on photos, for example. Does anyone have any ideas of how to solve this problem? Thanks!
  21. Hi I have problem when animating with CSS calc(). It's just jump to new position, without delay and animation. Is there any special way to do css math when tweening? How to make tween relative to viewport or container?
  22. I am using azazdeaz's great React GSAP library on a project. Thanks for your work azazdeaz! In my demo, you can see a bubble entering in from the bottom and leaving to the top. However in the `render` method's `return` you can see that more bubbles are meant to render based on the `state`'s `phase` value. The state value is incrementing as can be seen in the console log and React Dev Tools. So I guess the `slideAnim` function isn't updating when the `render`'s contents update. First solution I thought of was to run the animation again from a `componentDidUpdate`, but then it runs many more times than I want. As I write this I realise using `ReactCSSTransitionGroup` might be the ideal solution here. Could there be a neat solution for this situation using the React GSAP library?
  23. Hi all, Been working on an explosion component in React and ran across the Confetti Cannon on Codepen. Excellent GSAP work there. Then I forked that and tweaked it a bit to what I was aiming for in this codepen. So far, so good. Then I started integrating this with React and found that I had to do things a bit different due to the way React works. After a bit of mucking around I feel like I've got things at least set up right but I'm encountering a peculiar outcome I'm wondering if anyone could assist with. I'm not sure if my issue lies in React, GSAP, or possibly even the layout with CSS. Here's the React Explosion pen I'm working on (the main Codepen URL on this post). It appears as if everything seems to be working aside from the Physics2DPlugin. Anyone have any thoughts?
  24. Hello, First thanks for this nice library and fine the documentation you produced. I am working on a 2D SVG game built with react.js. Why react? Because its something I have already used and know and also because react.js is the hot lib nowadays... Turn out that I needed a solution to animate my SVG, I first tried plain CSS animation but the result weren't the same in different browser or platforms so I spent some time to look for a more robust solution and I end up going for GSAP. I quickly found out that GSAP and React aren't the best friend but things could be worked out, after reading forum I tried react-gsap-enhancer but well It didn't solve my issues. One of my goals was to have some SVG element animation in a loop inside different components and containers all getting their props from redux store. What happened is that loop were working fine at first but at some point after some rendering due to game activity loop animation stopped definitely... , I solved some of those issues by creating a react component (not stateless) for each svg I wanted to animate, using ref callback to get the element and starting the animation when componentDidMount() and preventing the component the rerender using shouldComponentUpdate(){return false} in order to prevent react from rerendering the component on every tick of a timer for example. So I thought I found a solution, I got my simple animation loop going in background only tweening 1 or 2 attribute like scale, a total of 5+ animation loop. Thats when I started to realized that the app got slower and checking the CPU usage it was at best around 140 just in idle mode (only open the web page), i removed all loop and it was back to 0 in idle mode. Thus here I come asking for help..., I do need animations for the game... I was about to go premium so I could add even more animation like particles and text animation... but now I do not know what I can do to prevent animation from killing players CPU also the game main target will be mobile phone... Is there anyway to hire a GSAP expert to look into those issues ? (please note its an indie game not so much $) Has anyone managed to make react and GSAP play well together to animate a bit more than just a svg rectangle or circle... but complex SVG with hundreds of paths ?
  25. Hi Everyone, I am having an issue integrating React with Timeline lite. I can successfully play, pause, and rewind a timeline but when I try to read the current time using .progress() on the timeline object, I get undefined. I want that progress() function because I want to create a slider bar that will report the progress of the timeline and hopefully also allow for it to be adjusted. My app is laid out like this, I have a container LectureLayout that has a draggableObjects container which itself has many draggable object components. I have a controls component which has the play, pause, reverse buttons. <LectureLayout> <DraggableObjects timeline={timeline}> <DraggableObject1> <DraggableObject2> <DraggableObject3> <Controls timeline={timeline}> I create a TimelineLite() and pass it as a prop into the draggable objects and controls components. I load up all of the tween animations in the Draggable Objects container but since it is a prop of the LectureLayout container, I can read that successfully in the Controls component. My main question is how can the .progress() function be returning undefined when I can use all of the other functions like play() and I can clearly see the timeline when I run a console.log export class Controls extends React.Component { constructor(props, context) { super(props, context); } play(event){ event.preventDefault(); this.props.timeline.play(); } componentDidMount(){ console.log(this.props.timeline) //Successfully gives me a timeline object console.log(this.props.timeline.progress()); //This comes up as undefined } render(){ console.log(this.props.timeline) //Successfully gives me a timeline object console.log(this.props.timeline.progress()); //This comes up as undefined return( <div> <Row> <ProgressBar/> </Row> <Row> <Button onClick={this.play.bind(this)} id="play">play()</Button> </Row> </div> ) } };
