Thanks for answer @OSUblake. Yeah it makes sense, I'll try to understand the code in helper function that you linked. I didn't put timeline in data() becuase of reactivity, but I put it there because of easy acces from methods (and that is the only way I know). For example I can simply play timeline by this.tl.play(). Is killing timeline necesarry?

Hello guys, Im trying to build a simple carousel slider in vue 2. First problem is that my timeline is initially paused (i heard that is a good practice) and if i click next or prev button my animation doesn't play. I found solution, but I don't know if it is right one. I mean, it works but when using prevSlide function animation back to first initial slide. (probably thats another not related problem) So my question is how to handle timelines in vue. Should I put timeline in mounted, and prevSlide and nextSlide functions should only play or reverse the timeline? temporary solution: nextSlide() { this.tl.to(gsap.utils.toArray(this.$refs.slider.children), { xPercent: "-=" + 100, onComplete: this.tl.pause() }); this.tl.play() } the main code: <template> <div id="app"> <div class="slider" ref="slider"> <div class="slide"></div> <div class="slide"></div> <div class="slide"></div> </div> <button @click="prevSlide">prev</button> <button @click="nextSlide">next</button> </div> </template> <script> import gsap from "gsap"; export default { name: "App", data() { return { currSlide: 1, tl: gsap.timeline({ paused: true }), }; }, methods: { nextSlide() { this.tl.to(gsap.utils.toArray(this.$refs.slider.children), { xPercent: "-=" + 100, }); }, prevSlide() { this.tl.to(gsap.utils.toArray(this.$refs.slider.children), { xPercent: "-=" - 100, }); }, }, mounted() {}, }; </script> <style> #app { font-family: "Avenir", Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } .slider { width: 600px; height: 350px; display: flex; flex-direction: row; overflow: hidden; } .slide { width: 100%; height: 100%; flex-shrink: 0; } .slide:nth-child(1) { background: crimson; } .slide:nth-child(2) { background: green; } .slide:nth-child(3) { background: darkcyan; } </style> Code playground down below https://codesandbox.io/s/gracious-fog-y4b8d?file=/src/App.vue
