今回はマウスカーソルの動きに合わせたアニメーションの設定を行います。

js/main.js

// use a script tag or an external JS file
document.addEventListener("DOMContentLoaded", (event) => {
  gsap.registerPlugin(ScrollTrigger);
  new App();
});

class App {
  constructor() {
    this._initialize();
    this._renderLenis();
  }

  _initialize() {
    this._createLenis();
    this._sec1Anime();
    this._sec2Anime();
  }

  _createLenis() {
    this.lenis = new Lenis();
  }

  _renderLenis(time) {
    this.lenis.raf(time);
    requestAnimationFrame(this._renderLenis.bind(this));
  }

  _sec1Anime() {
    const loadingEl = document.querySelector("#loading");
    const loadingTexts = loadingEl.textContent.split("");
    let innerText = "";

    loadingTexts.forEach((text) => {
      innerText += `<span>${text}</span>`;
    });

    // console.log(loadingTexts);
    // console.log(innerText);

    loadingEl.innerHTML = innerText;

    const tl = gsap.timeline({ repeat: -1 });

    tl.to("#loading span", {
      duration: 1,
      y: -50,
      stagger: {
        each: 0.2,

    const strokeElHeight = strokeEl.clientHeight;
    const rectX = strokeEl.getBoundingClientRect().left;
    const rectY = strokeEl.getBoundingClientRect().top;

    let orgPath = `M 20 ${strokeElHeight / 2} Q 480 ${strokeElHeight / 2} 980 ${

    }`;

    gsap.set("svg path", {

      let strokeQX = e.x - rectX;
      let strokeRectY = e.y - rectY;

      if (strokeRectY > strokeElHeight / 2) {
        strokeQY = strokeRectY - strokeElHeight / 2;
      } else {
        strokeQY = strokeRectY + strokeElHeight / 2;
      }

      let path = `M 20 ${strokeElHeight / 2} Q ${strokeQX} ${strokeQY} 980 ${

      }`;

      gsap.to("svg path", {

        },
        duration: 0.3,
