使用electron制作满屏心特效的示例代码

本文介绍了使用electron制作满屏心特效的示例代码，分享给大家，具体如下：

图片被压缩了看起来很难看

主进程代码

import {BrowserWindow, app, ipcMain} from 'electron'

createWindow();

ipcMain.on('quitApp', () => {
  app.quit();
});

function createWindow() {

  const loginURL = process.env.NODE_ENV === 'development' ? `http://localhost:9080` : `file://${__dirname}/index.html`;
  const win = new BrowserWindow({

    alwaysOnTop: true,
    modal: true,
    width: 1200,
    height: 6500,
    frame: false,
    show: false,
    darkTheme: true,
    resizable: false,
    minimizable: false,
    maximizable: false,
    transparent: true,
    type: 'toolbar',
    webPreferences: {
      devTools: false,
    }
  });
  win.loadURL(loginURL);
  win.once('ready-to-show', () => {
    win.show();
  });
}

界面代码

js代码

 mounted() {
      var hearts = [];
      var canvas = this.$refs.drawHeart;
      var wW = 1920;
      var wH = 1040;
      // 创建画布
      var ctx = canvas.getContext('2d');
      // 创建图片对象
      var heartImage = new Image();
      heartImage.src = img;
      var num = 100;

      init();

      window.addEventListener('resize', function(){
 wW = window.innerWidth;
 wH = window.innerHeight;
      });
      // 初始化画布大小
      function init(){
 canvas.width = wW;
 canvas.height = wH;
 for(var i = 0; i < num; i++){
   hearts.push(new Heart(i%5));
 }
 requestAnimationframe(render);
      }

      function getColor(){
 var val = Math.random() * 10;
 if(val > 0 && val <= 1){
   return '#00f';
 } else if(val > 1 && val <= 2){
   return '#f00';
 } else if(val > 2 && val <= 3){
   return '#0f0';
 } else if(val > 3 && val <= 4){
   return '#368';

   return '#e96d5b';
 } else if(val > 8 && val <= 9){
   return '#5be9e9';
 } else {
   return '#d41d50';
 }
      }

      function getText(){
 var val = Math.random() * 10;
 if(val > 1 && val <= 3){
   return '爱你一辈子';
 } else if(val > 3 && val <= 5){
   return '感谢你';
 } else if(val > 5 && val <= 8){
   return '喜欢你';
 } else{
   return 'I Love You';
 }
      }

      function Heart(type){
 this.type = type;
 // 初始化生成范围
 this.x = Math.random() * wW;
 this.y = Math.random() * wH;

 this.opacity = Math.random() * .5 + .5;

 // 偏移量
 this.vel = {
   x: (Math.random() - .5) * 5,
   y: (Math.random() - .5) * 5
 }

 this.initialW = wW * .5;
 this.initialH = wH * .5;
 // 缩放比例
 this.targetScale = Math.random() * .15 + .02; // 最小0.02
 this.scale = Math.random() * this.targetScale;

 // 文字位置
 this.fx = Math.random() * wW;
 this.fy = Math.random() * wH;
 this.fs = Math.random() * 10;
 this.text = getText();

 this.fvel = {
   x: (Math.random() - .5) * 5,
   y: (Math.random() - .5) * 5,
   f: (Math.random() - .5) * 2
 }
      }

      Heart.prototype.draw = function(){
 ctx.save();
 ctx.globalAlpha = this.opacity;
 ctx.drawImage(heartImage, this.x, this.y, this.width, this.height);
 ctx.scale(this.scale + 1, this.scale + 1);
 if(!this.type){
   // 设置文字属性
   ctx.fillStyle = getColor();
   ctx.font = 'italic ' + this.fs + 'px sans-serif';
   // 填充字符串
   ctx.fillText(this.text, this.fx, this.fy);
 }
 ctx.restore();
      }
      Heart.prototype.update = function(){
 this.x += this.vel.x;
 this.y += this.vel.y;

 if(this.x - this.width > wW || this.x + this.width < 0){
   // 重新初始化位置
   this.scale = 0;
   this.x = Math.random() * wW;
   this.y = Math.random() * wH;
 }
 if(this.y - this.height > wH || this.y + this.height < 0){
   // 重新初始化位置
   this.scale = 0;
   this.x = Math.random() * wW;
   this.y = Math.random() * wH;
 }

 // 放大
 this.scale += (this.targetScale - this.scale) * .1;
 this.height = this.scale * this.initialH;
 this.width = this.height * 1.4;

 // -----文字-----
 this.fx += this.fvel.x;
 this.fy += this.fvel.y;
 this.fs += this.fvel.f;

 if(this.fs > 50){
   this.fs = 2;
 }

 if(this.fx - this.fs > wW || this.fx + this.fs < 0){
   // 重新初始化位置
   this.fx = Math.random() * wW;
   this.fy = Math.random() * wH;
 }
 if(this.fy - this.fs > wH || this.fy + this.fs < 0){
   // 重新初始化位置
   this.fx = Math.random() * wW;
   this.fy = Math.random() * wH;
 }
      }

      function render(){
 ctx.clearRect(0, 0, wW, wH);
 for(var i = 0; i < hearts.length; i++){
   hearts[i].draw();
   hearts[i].update();
 }
 requestAnimationframe(render);
      }

    }

扩展功能

全屏展示

const size = screen.getPrimaryDisplay().workAreaSize;  //获取显示器的宽高
win.setSet(size.width size.height);
win.setPosition(0,0);

这样就会让窗口全屏但是有一个问题就是这样做界面不会正确响应我们可以使用进程通信去解决

win.webContents.sen('windowSize',size);

之后再主进程中监听就行了

窗口点击穿透

以上代码会有一个问题就是一旦运行就不能关闭了

win.setIgnoreMouseEvents(true) 就可以让界面只做展示使用鼠标可以点击你窗口的任意区域

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持考高分网。
