關於vue3使用particles粒子特效的問題

不知道大傢有沒有被particles惡心過,反正這東西是教育瞭我一下午時間。

起初我想直接用 vue-particles 這個插件去做,但我驚訝的發現,好像不頂用。

vue-particles 內部用瞭 require 這個api,vue3已經全面棄用瞭require,去擁抱 commonJSes6 瞭,改動瞭一個地方,其他地方也會出問題。

第一步:引入 particles.js

npm i particles.js
or
yarn add particles.js

第二步:找到 node_modules 內的 particles.js

把它弄出來 :

弄出來後可以用 npm uninstall particles.js 將依賴去除

第三步:項目 components 下創建 particles 目錄

將找到的 particles.js 放進去後,在其同級目錄創建 index.vue 與 particles.json:

第四步:index.vue 寫入以下內容

<template>
  <div class="particles-js-box">
    <div id="particles-js"></div>
  </div>
</template>
<script>
/* eslint-disable */
import particlesJs from "./particles.js";
import particlesConfig from "./particles.json";
export default {
  data() {
    return {};
  },
  mounted() {
    this.init();
  },
  methods: {
    init() {
      particlesJS("particles-js", particlesConfig);
      document.body.style.overflow = "hidden";
    },
  },
};
</script>
<style scoped>
.particles-js-box {
  position: fixed;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: 1;
}
#particles-js {
  background-color: #2d3a4b;
  width: 100%;
  height: 100%;
}
</style>

第五步:particles.json 寫入以下內容

{
    "particles": {
        "number": {
            "value": 60,
            "density": {
                "enable": true,
                "value_area": 800
            }
        },
        "color": {
            "value": "#ffffff"
        },
        "shape": {
            "type": "circle",
            "stroke": {
                "width": 0,
                "color": "#000000"
            },
            "polygon": {
                "nb_sides": 5
            },
            "image": {
                "src": "img/github.svg",
                "width": 100,
                "height": 100
            }
        },
        "opacity": {
            "value": 0.5,
            "random": false,
            "anim": {
                "enable": false,
                "speed": 1,
                "opacity_min": 0.1,
                "sync": false
            }
        },
        "size": {
            "value": 3,
            "random": true,
            "anim": {
                "enable": false,
                "speed": 40,
                "size_min": 0.1,
                "sync": false
            }
        },
        "line_linked": {
            "enable": true,
            "distance": 150,
            "color": "#ffffff",
            "opacity": 0.4,
            "width": 1
        },
        "move": {
            "enable": true,
            "speed": 4,
            "direction": "none",
            "random": false,
            "straight": false,
            "out_mode": "out",
            "bounce": false,
            "attract": {
                "enable": false,
                "rotateX": 100,
                "rotateY": 1200
            }
        }
    },
    "interactivity": {
        "detect_on": "Window",
        "events": {
            "onhover": {
                "enable": true,
                "mode": "grab"
            },
            "onclick": {
                "enable": true,
                "mode": "push"
            },
            "resize": true
        },
        "modes": {
            "grab": {
                "distance": 140,
                "line_linked": {
                    "opacity": 1
                }
            },
            "bubble": {
                "distance": 400,
                "size": 40,
                "duration": 2,
                "opacity": 8,
                "speed": 3
            },
            "repulse": {
                "distance": 200,
                "duration": 0.4
            },
            "push": {
                "particles_nb": 4
            },
            "remove": {
                "particles_nb": 2
            }
        }
    },
    "retina_detect": true
}

第六步:修改 particles.js

1、1416行 – 1427行 替換為:

Object.deepExtend = function f(destination, source) {
  for (var property in source) {
    if (source[property] && source[property].constructor &&
     source[property].constructor === Object) {
      destination[property] = destination[property] || {};
      f(destination[property], source[property])
    } else {
      destination[property] = source[property];
    }
  }
  return destination;
};

2、最後一行添加:

export default window.particlesJS 

第七步:引入這裡的index.vue

<template>
  <div>
    <particles></particles>
  </div>
</template>
<script>
import Particles from '@/components/particles/index.vue'
export default {
  components: {
    "particles":Particles
  }
};
</script>

以上七步足矣! 這些僅為個人經驗,希望能給大傢一個參考,也希望大傢多多支持WalkonNet。
