html5仿淘宝,京东实现红包雨结果（代码实例）-
发布时间：09/01 来源：未知 浏览：
关键词：
本红包雨项目是基于HTML5的游戏框架Phaser写的,终究构成的是一个canvas,所以机能非常不错,但是必需要说的是这个框架比拼大,紧缩后也有700K摆布,所以请慎用.
代码地址: https://github.com/AmosXu/red-packet-rain
1. 结果展现
图片顺次是倒计时页面,抢红包页面,拆红包页,红包展现页,这些页面都是写在一个canvas里面的,无刷新的切换结果,机能超级棒
2.代码展现
贴上主要的代码js代码和注释

}3. 疑问题目
1. 游戏暂停时,点击事件无效,需要点击,怎么解决
答: 通过全局事件画热点的情势绑定事件,一定要记得移除事件,一定一定要记得
game.input.onDown.add(clickOpen, this) //给游戏绑定全局事件
let userTicket = game.add.sprite(rfuc(78), rfuc(445), 'buttonUseTicket')
let userTicketRect = new Phaser.Rectangle(78, 445, 194, 66).copyFrom(userTicket); //获得button的区域
//要是点击的位置为button的位置就施行下一步
if (userTicketRect.contains(game.input.x, game.input.y)) {
//移除全局事件
game.input.onDown.remove(clickButton, this);
}2. 文字或图片相关于屏幕居中(临时只能做屏幕居中)
答: 增加文字到游戏中,文字向左的偏移量等于游戏屏幕的宽度减去文字宽度的个别,就能达到居中的结果
ticketText = game.add.text(0, rfuc(338), '我想居中',
{fill: '#ffe67d', fontSize: '46px', fontWeight: 'bolder'})
ticketText.left = game.world.centerX - ticketText.width / 2 //文字相关于屏幕摆布居中代码地址: https://github.com/AmosXu/red-packet-rain
