Animation not working as expected

Recommended Posts

I'm trying to animate an intro page with an intro text and an arrow in the following sequence:

The background image is moved back and forth twice. After that, the arrow should scale from 1 to 1.5 and be rescaled again to the original size

The intro text should also be scaled to 1.5 and rescaled to its original size

For some reason, the arrow and text are scaled to 1.5 from the very start, how can I preserve the size for the arrow and the text while the background image inimation is still running?

Here is the code sofar:

 

<html>
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=yes">
    <meta charset="utf-8">
    <style type="text/css">
        .intro-text {
            display: block;
            font-size: 16px !important;
            text-transform: uppercase;
            font-weight: bold;
            position: fixed;
            top: 50%;
            right: 140px;
            z-index: 99;
            color: red;
        }
        
        .intro-arrow {
            display: block;
            font-size: 16px !important;
            text-transform: uppercase;
            font-weight: bold;
            position: fixed;
            top: 45%;
            right: 70px;
            z-index: 99;
            color: white;
        }
    </style>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.1.1/gsap.min.js" crossorigin="anonymous"></script>
    <script>
            var tl = new TimelineMax();
            tl
            .fromTo("body", 0.5,  {x:-15}, {x:0})
            .fromTo("body", 0.5,  {x:-15}, {x:0})
            .fromTo('.intro-arrow', 0.5, {scale: 1},{scale: 1.5})
            .fromTo('.intro-arrow', 0.5, {scale: 1.5},{scale: 1})
            .fromTo('.intro-text', 0.5, {scale: 1}, {scale: 1.5})
            .fromTo('.intro-text', 0.5, {scale: 1.5}, {scale: 1})

Hey Gunther and welcome to the GreenSock forums! I actually just answered your post on StackOverflow.

 

This is because you're animating using .fromTo(). .from() and .fromTo()s by default have immediateRender set to true (because generally that's what people want). You can set immediateRender to false for the tweens that are causing the scaling issue.

 

Alternatively, just use .to() calls instead. Using repeat and yoyo could also make your job easier. How I'd write it in GSAP 3 format:

var tl = gsap.timeline();
tl
  .fromTo("body", {x: -15}, {x: 0, repeat: 1})
  .to('.intro-arrow', {scale: 1.5, repeat: 1, yoyo: true})
  .to('.intro-text', {scale: 1.5, repeat: 1, yoyo: true})

 

The duration can be left out since 0.5 is the default in GSAP 3. If you want to change the duration for a tween, we recommend that you put it inside of the vars parameter, like duration: 1.

 

We highly recommend the Getting Started article as you can learn a lot of things similar to this :)
