Built-in animations plugin powered by GSAP libraries

Recommended Posts

Hello everyone,

 

I have worked on JS-based animations with GSAP libraries for one year.

The product I am working on is that provides User 

Mostly, I use TimelineMax to create timeline animations by using top/left, opacity, scale,... properties.

I think my app will be better if I can combine Built-in animations with Timeline, then I can schedule the built animation with duration and offset in my timeline.

Built-in animations for example: bounce, slideIn, flash,... reference here: https://daneden.github.io/animate.css/

 

It's a big challenge to translate from CSS to GSAP based Javascript animations.

So I am looking for a plugin powered by GSAP Timeline libs.

 

Please tell me if you have any plugin like that.

 

Thanks a lot.

We don't really have "built-in" effects, but the engine is very flexible and excels at allowing you to create your own re-usable effects.

 

I would strongly recommend reading this article and watching the videos if you need help with the concept of "creating functions that return animations".

 

https://css-tricks.com/writing-smarter-animation-code/

 

The general idea is that you can build a timeline consisting of animations that are created via parameterized functions.

Below is a very basic implementation of this idea with 2 effects "bounceScale" and "spinAndThenFadeOut"

 

Notice how each box bounces and scales with unique parameters (scale amount, duration) and then each box spins and fades out with unique rotations and speed.

 

//effect function animates an element and returns the tween
function bounceScale(element, endScale, duration) {
  var tween = TweenLite.to(element, duration, {scale:endScale, ease:Bounce.easeOut});
  return tween;
}

//effect function animates an element and returns the timeline
function spinAndThenFadeOut(element, spinSpeed, spinAmount){
  var tl = new TimelineLite()
  tl.to(element, spinSpeed, {rotation:spinAmount})
    .to(element, 0.5, {opacity:0});
  return tl;
}



// build timeline using multiple effects on multiple elements with unique parameters
var tl = new TimelineMax();
 tl.add(bounceScale(box1, 3, 1))
   .add(bounceScale(box2, 0.5, 2))
   .add(bounceScale(box3, 0.2, 1))
   .add(spinAndThenFadeOut(box3, 2, 720), "+=0.5")
   .add(spinAndThenFadeOut(box2, 0.5, 180))
   .add(spinAndThenFadeOut(box1, 3, 360))

Also, for parameterized wiggles and bounces, be sure to check out the eases CustomWiggle and CustomBounce:

As a Club GreenSock member you have access to these powerful tools. I think you will enjoy them.
