# solved random radius on staggerTo yoyo

## Recommended Posts

Hey any tips or suggest to perform a kind of reel infinite random motions?
I find my approach too redundant.

Example on text matrix?
I get a random behavior, but alway same from looping !

this is currently the code

```    startMotion(){
const List = this.child.Master.children; //words
//!motions words
if('option motions words'){
gsap.staggerFromTo(List, 0.5, {alpha:0},{alpha:1, ease: Power1.easeIn}, 0.4);
gsap.staggerTo(List, 4, {
x:()=>`+=\${Math.randomFrom(4,-8)}`,
y:()=>`+=\${Math.randomFrom(7,-10)}`,
ease: Power1.easeInOut, repeat:-1, yoyo:true}, 0.2);
};
};```

What i would like it a way to compute a random range from a radius ? but alway random after loop cycle.
Do gsap have a native easy feature to perform this?
suggest welcome

In gsap 3, you can do this for random.

```gsap.staggerTo(List, 4, {
x: "random(4,-8)",
y: "random(7,-10)",
ease: Power1.easeInOut, repeat:-1, yoyo:true}, 0.2);```

There are also random utils.

I like to animate x and y independent of each other.

@GreenSock This syntax taken from the docs isn't working. I have to enter a snap increment for it to work.

`var random = gsap.utils.random(-10, 50, true);`

In GSAP 3 it's best to not use the old `staggerTo` methods. All tweens have the ability to stagger! This is the same thing that Blake posted in all-GSAP 3 recommended ways:

```gsap.to(List, {
duration: 4,
x: "random(4,-8)",
y: "random(7,-10)",
ease: "power1.inOut",
repeat: -1,
yoyo: true,
stagger: 0.2
});```

Good catch. Should be resolved in the next release: https://s3-us-west-2.amazonaws.com/s.cdpn.io/16327/gsap-latest-beta.min.js

I forgot about computed property names. Here's another version of my animation using a single function.
