前言

之前魔改博客的过程都没记录下来，感觉回头要重构的时候会很麻烦

那么就从这篇开始记录魔改博客的过程吧

参考：https://www.smoe.top/2020/12/27/Hexo-click/

注：实现这些效果需要先引入jQuery

<script type="text/javascript" src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>

然后在layout文件里面引入对应的js文件

<script type = "text/javascript" src = "<%- url_for("/js/love-click.js") %>"></script>

烟花特效

即我现在使用的这个特效

class Circle {
  constructor({ origin, speed, color, angle, context }) {
    this.origin = origin
    this.position = { ...this.origin }
    this.color = color
    this.speed = speed
    this.angle = angle
    this.context = context
    this.renderCount = 0
  }

  draw() {
    this.context.fillStyle = this.color
    this.context.beginPath()
    this.context.arc(this.position.x, this.position.y, 2, 0, Math.PI * 2)
    this.context.fill()
  }

  move() {
    this.position.x = (Math.sin(this.angle) * this.speed) + this.position.x
    this.position.y = (Math.cos(this.angle) * this.speed) + this.position.y + (this.renderCount * 0.3)
    this.renderCount++
  }
}

class Boom {
  constructor ({ origin, context, circleCount = 16, area }) {
    this.origin = origin
    this.context = context
    this.circleCount = circleCount
    this.area = area
    this.stop = false
    this.circles = []
  }

  randomArray(range) {
    const length = range.length
    const randomIndex = Math.floor(length * Math.random())
    return range[randomIndex]
  }

  randomColor() {
    const range = ['8', '9', 'A', 'B', 'C', 'D', 'E', 'F']
    return '#' + this.randomArray(range) + this.randomArray(range) + this.randomArray(range) + this.randomArray(range) + this.randomArray(range) + this.randomArray(range)
  }

  randomRange(start, end) {
    return (end - start) * Math.random() + start
  }

  init() {
    for(let i = 0; i < this.circleCount; i++) {
      const circle = new Circle({
        context: this.context,
        origin: this.origin,
        color: this.randomColor(),
        angle: this.randomRange(Math.PI - 1, Math.PI + 1),
        speed: this.randomRange(1, 6)
      })
      this.circles.push(circle)
    }
  }

  move() {
    this.circles.forEach((circle, index) => {
      if (circle.position.x > this.area.width || circle.position.y > this.area.height) {
        return this.circles.splice(index, 1)
      }
      circle.move()
    })
    if (this.circles.length == 0) {
      this.stop = true
    }
  }

  draw() {
    this.circles.forEach(circle => circle.draw())
  }
}

class CursorSpecialEffects {
  constructor() {
    this.computerCanvas = document.createElement('canvas')
    this.renderCanvas = document.createElement('canvas')

    this.computerContext = this.computerCanvas.getContext('2d')
    this.renderContext = this.renderCanvas.getContext('2d')

    this.globalWidth = window.innerWidth
    this.globalHeight = window.innerHeight

    this.booms = []
    this.running = false
  }

  handleMouseDown(e) {
    const boom = new Boom({
      origin: { x: e.clientX, y: e.clientY },
      context: this.computerContext,
      area: {
        width: this.globalWidth,
        height: this.globalHeight
      }
    })
    boom.init()
    this.booms.push(boom)
    this.running || this.run()
  }

  handlePageHide() {
    this.booms = []
    this.running = false
  }

  init() {
    const style = this.renderCanvas.style
    style.position = 'fixed'
    style.top = style.left = 0
    style.zIndex = '999999999999999999999999999999999999999999'
    style.pointerEvents = 'none'

    style.width = this.renderCanvas.width = this.computerCanvas.width = this.globalWidth
    style.height = this.renderCanvas.height = this.computerCanvas.height = this.globalHeight

    document.body.append(this.renderCanvas)

    window.addEventListener('mousedown', this.handleMouseDown.bind(this))
    window.addEventListener('pagehide', this.handlePageHide.bind(this))
  }

  run() {
    this.running = true
    if (this.booms.length == 0) {
      return this.running = false
    }

    requestAnimationFrame(this.run.bind(this))

    this.computerContext.clearRect(0, 0, this.globalWidth, this.globalHeight)
    this.renderContext.clearRect(0, 0, this.globalWidth, this.globalHeight)

    this.booms.forEach((boom, index) => {
      if (boom.stop) {
        return this.booms.splice(index, 1)
      }
      boom.move()
      boom.draw()
    })
    this.renderContext.drawImage(this.computerCanvas, 0, 0, this.globalWidth, this.globalHeight)
  }
}

const cursorSpecialEffects = new CursorSpecialEffects()
cursorSpecialEffects.init()

文字特效

这个也是我正在使用的特效

var a_idx = 0;
jQuery(document).ready(function ($) {
  $("body").click(function (e) {
    var a = new Array("Pure", "Far", "Lost", "Perfect", "Great", "Miss", "Bad");
    var $i = $("<span/>").text(a[a_idx]);
    var x = e.pageX,
      y = e.pageY;
    $i.css({
      "z-index": 99999,
      "top": y - 28,
      "left": x - a[a_idx].length * 8,
      "position": "absolute",
      "color": "rgb(" + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + ")"
    });
    $("body").append($i);
    $i.animate({
      "top": y - 180,
      "opacity": 0
    }, 1500, function () {
      $i.remove();
    });
    a_idx = (a_idx + 1) % a.length;
  });
});
