Einfache Animationen

gsap.to(".logo", {duration: 2, x: 300}); // Dies nennt sich eine Timeline. 300px nach rechts bewegen in 2s mit Standardwerten (ease out...) gsap.to(".logo", {duration: 2, x: 300, backgroundColor: "#c2c4c8"}); // CSS Eigenschaften die normal ein - haben, werden als Camelcase geschrieben. // Eigenschaften mit Zeichen in Anführungsstrichen. Fast alles lässt sich Animieren. gsap.to(".logo", {duration: 2, x: 300, backgroundColor: "#c2c4c8", borderRadius: "50%", border: "4px solid white"});

Ease In Out

https://greensock.com/docs/v3/Eases
gsap.to(".logo", {duration: 1, x:300, ease: "power2.inOut"});

Ease Möglichkeiten

//OLD ==> NEW
Elastic.easeOut ==> "elastic.out" //or just "elastic" because ".out" is the default flavor
Elastic.easeIn ==> "elastic.in"
Elastic.easeInOut ==> "elastic.inOut"
Elastic.easeOut.config(1, 0.5) ==> "elastic.out(1, 0.5)" //or just "elastic(1, 0.5)"

//and the other configurable eases are much easier!:
SteppedEase.config(5) ==> "steps(5)"
SlowMo.ease.config(0.5, 0.8) ==> "slow(0.5, 0.8)"
RoughEase.ease.config({points:40}) ==> "rough(40)"
ExpoScaleEase.config(0.5, 3) ==> "expoScale(0.5, 3)"

Staggering

gsap.to(".class", {
  x:"+=100",
  duration:1,
  stagger: 0.5 //simple stagger of 0.5 seconds
});

//or get advanced:
gsap.to(".class", {
  x:"+=100",
  duration:1,
  stagger: {
    amount:2,
    from:"center",
    grid:"auto",
    onComplete: myFunction //define callbacks inside the stagger to make them apply to each sub-tween
  }
});

Relative position prefix

Relative “>” and “<” position prefix This feature helps with positioning animations in a timeline. It puts a tween relative to the previous tween’s start or end time and removes the need to add labels through your code.

gsap.method('selector',{}, "<" ) //Inserts a tween at the start of the previous tween

gsap.method('selector',{}, ">" ) //Inserts a tween at the end of the previous

Keyframes

Anstatt mehrerer Tweens kann man auch mehrere TweenProperties als keyframes kombinieren und hat weniger Tipparbeit.

gsap.to(".class", {keyframes: [ //<-- an array of keyframes!
  {x:100, duration:1},
  {y:200, duration:1, delay:0.5}, //create a 0.5 second gap
  {rotation:360, duration:2, delay:-0.25} //overlap by 0.25 seconds
]});

Globale Timeline kontrollieren

gsap.globalTimeline.timeScale(0.1); //slow everything down gsap.globalTimeline.pause(); //stop everything, though you might want to use gsap.exportRoot() instead so that you can exclude delayedCalls()

Rotation

Richtung der Rotation

rotation:"270_short" //animates in the shortest direction!
rotation:"270_cw"    //animates clockwise
rotation:"270_ccw"   //animates counter-clockwise

Scroll To

document.querySelector("button").addEventListener("click", function() {
  gsap.to(window, { duration: 0.75, scrollTo: ".target" });
});

GSAP Scroll Trigger

Update: Die beste Möglichkeit ist mit dem neuen ScrollTrigger Plugin.

Good Practice and Time Savers

Timeline schneller abspielen

tl.timeScale(3).repeat(2);

Bestimmten Teil abspielen

tl.play("myLabel");

wobei die Labels so definiert werden:

.addLabel("out3");

oder

.to("#myElement",{duration:1, rotation:90}, "in3");

Schleifen

Geeignet für gleiche Animation auf mehreren Elementen hintereinander. Dabei übergeben wir in einer Schleife ein DOM Element und erstellen in einer anonymen Funktion den Tween.

$(".fade-in").each(function(){
  var tween = gsap.from($(this), {duration: 0.5, scale: 0.7, y: '+=30', ease: Linear.easeNone });
  // possible with ScrollMagic
  var scene = new ScrollMagic.Scene({
    triggerElement: this,
  })
    .setTween(tween);
});

Default Werte

gsap.timeline({defaults:{ease:"power2.out", duration:5}})
    .to(".selector1", {x:200})
    .to(".selector2", {y:500})
