Usage

import * as React from "react";
import { animated } from "react-spring";
import { useStepAnimation } from "use-step-animation";

const Example = () => {
  const wrapperRef = React.useRef();
  const stepOneRef = React.useRef();
  const stepTwoRef = React.useRef();
  const stepThreeRef = React.useRef();
  const stepFourRef = React.useRef();
  const stepFiveRef = React.useRef();

  const { animationProps, step, nextStep, previousStep } = useStepAnimation({
    wrapperRef,
    stepsRef: [stepOneRef, stepTwoRef, stepThreeRef, stepFourRef, stepFiveRef],
    offset: { x: 0, y: 0 },
    queueTime: 1000,
    getPositionsAwaitTime: 0,
  });
