本红包雨项目是基于HTML5的游戏框架Phaser写的,最终形成的是一个canvas,所以性能很好,但是必须要说的是这个框架比较大,压缩后也有700K左右,所以请慎用.
代码地址: https://github.com/AmosXu/red-packet-rain
图片依次是倒计时页面,抢红包页面,拆红包页,红包展示页,这些页面都是写在一个canvas里面的,无刷新的切换效果,性能超级棒
贴上主要的代码js代码和注释

}答: 通过全局事件画热点的形式绑定事件,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), &＃39;buttonUseTicket&＃39;)
let userTicketRect = new Phaser.Rectangle(78, 445, 194, 66).copyFrom(userTicket); //获得button的区域
//如果点击的位置为button的位置就执行下一步
if (userTicketRect.contains(game.input.x, game.input.y)) {
//移除全局事件
game.input.onDown.remove(clickButton, this);
}答: 添加文字到游戏中,文字向左的偏移量等于游戏屏幕的宽度减去文字宽度的一般,就能达到居中的效果
ticketText = game.add.text(0, rfuc(338), &＃39;我想居中&＃39;,
{fill: &＃39;#ffe67d&＃39;, fontSize: &＃39;46px&＃39;, fontWeight: &＃39;bolder&＃39;})
ticketText.left = game.world.centerX - ticketText.width / 2 //文字相对于屏幕左右居中代码地址: https://github.com/AmosXu/red-packet-rain
