一步一步完成一个聚会摇色子游戏

      出去聚会想玩摇色子，奈何身边没有色子，网上也没找到，自己写一个吧

一、画界面

      色子要大明显字要大，摇动最好有特效和声音，前端使用layui布局

1.引用

<link href="/plugin/layui/css/layui.css" rel="stylesheet">
<script src="/Scripts/jquery-1.8.2.min.js"></script>

2.布局

<div class="mybody" style="padding-top:100px">
    <div class="layui-row">
        <div class="layui-col-xs8">
            <div id="dice" class="dice dice_1 sezi1"></div>
        </div>
        <div class="layui-col-xs4">
            <div id="dice" class="dice dice_1 sezi2"></div>
        </div>
    </div>
    <div class="layui-row">
        <div class="layui-col-xs-offset4">
            <div id="dice" class="dice dice_1 sezi3"></div>
        </div>
    </div>
    <div class="layui-row">
        <div class="layui-col-xs8">
            <div id="dice" class="dice dice_1 sezi4"></div>
        </div>
        <div class="layui-col-xs4">
            <div id="dice" class="dice dice_1 sezi5"></div>
        </div>
    </div>
    <div class="layui-row">
        <div class="layui-col-xs-offset4">
           <button id="btnAll" class="layui-btn layui-btn-danger">一键全部摇</button>
        </div>
    </div>
</div>

3.适应手机

  <meta name="renderer" content="webkit">
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

先用按钮实现点击就摇动色子，产生结果

二、摇动特效

   //色子摇动特效,设置点数
    function startJump(index) {
        var dice = $(".dice").eq(index);
        $(".wrap").append("<div id='dice_mask'></div>");//加遮罩
        dice.attr("class", "dice");//清除上次动画后的点数
        dice.css('cursor', 'default');
        var num = Math.floor(Math.random() * 6 + 1);//产生随机数1-6
        dice.animate({ left: '+2px' }, 100, function () {
            dice.addClass("dice_t");
        }).delay(200).animate({ top: '-2px' }, 100, function () {
            dice.removeClass("dice_t").addClass("dice_s");
        }).delay(200).animate({ opacity: 'show' }, 600, function () {
            dice.removeClass("dice_s").addClass("dice_e");
        }).delay(100).animate({ left: '-2px', top: '2px' }, 100, function () {
            dice.removeClass("dice_e").addClass("dice_" + num);
            $("#result").html("您掷得点数是<span>" + num + "</span>");
            dice.css('cursor', 'pointer');
            $("#dice_mask").remove();//移除遮罩

            if (index == 4)
            {
                isJumping = false;
            }
        });
    }

因为index是索引，一共5个封装一个函数

先实现一个色子摇动

5个色子同时摇动

            startJump(0);
            startJump(1);
            startJump(2);
            startJump(3);
            startJump(4);    

三、监听手机摇动事件

<script>
    var SHAKE_THRESHOLD = 4500;  //定义触发动作的阈值
    var last_update = 0;         //上一次触发的时间
    var x = y = z = last_x = last_y = last_z = 0;//x,y,z当前加速度,last_z,last_x,last_y上次加速度<span style="font-size:18px;"></span>
    var isJumping = false;
</script>

<!--摇一摇内置脚本-->
<script>    
    function deviceMotionHandler(eventData) {
        var acceleration = eventData.accelerationIncludingGravity;
        var curTime = new Date().getTime();
        if ((curTime - last_update) > 100) {
            var diffTime = curTime - last_update;
            last_update = curTime;
            x = acceleration.x;
            y = acceleration.y;
            z = acceleration.z;
            var speed = Math.abs(x + y + z - last_x - last_y - last_z) / diffTime * 10000;
           
            if (speed > SHAKE_THRESHOLD) {
                //alert("speed:"+speed);
                //alert("SHAKE_THRESHOLD" + SHAKE_THRESHOLD);
                //摇动成功触发这个函数
                handelShakingMotion();              
            }
            last_x = x;
            last_y = y;
            last_z = z;
        }
    }
    //监听摇一摇的动作
    function listenPhoneShake() {
        if (window.DeviceMotionEvent) {
            window.addEventListener('devicemotion', deviceMotionHandler, false);
            console.log("addEventListener devicemotion");
        } else {
            alert('抱歉，你的手机配置实在有些过不去，考虑换个新的再来试试吧');
        }
    }
</script>

手机页面$(function(){})执行 listenPhoneShake()函数 赋予事件，其中

SHAKE_THRESHOLD 这个变量是摇动的震动值 如果该值越大那么要很用力摇手机才会触发自定义函数部署到IIS用手机测试可以了变量isJumping设置摇动时候不能并发摇动防止不停摇动出现BUG 在index=4中处理

四、色子滚动时候添加声音

1.添加标签

<audio src="/css/Mobile/Images/music.mp3" preload="preload" id="shakingAudio">

2.播放

 $('#shakingAudio').get(0).play();

3.兼容性处理（Android下直接播放没问题,IOS添加如下代码）

 //处理iphone不能自动播放  
        document.addEventListener('WeixinJSBridgeReady', function () {
            $('#shakingAudio').get(0).play();
        }, false);

五、完整html代码

@{
    ViewBag.Title = "摇色子";
    Layout = "~/Areas/Admin/Views/Shared/_LayoutAdmin.cshtml";
}

<!DOCTYPE html>
<link href="~/css/Mobile/sezi.css" rel="stylesheet" />
<audio src="/css/Mobile/Images/music.mp3" preload="preload" id="shakingAudio">

</audio>  
<div class="mybody" style="padding-top:100px">
    <div class="layui-row">
        <div class="layui-col-xs8">
            <div id="dice" class="dice dice_1 sezi1"></div>
        </div>
        <div class="layui-col-xs4">
            <div id="dice" class="dice dice_1 sezi2"></div>
        </div>
    </div>
    <div class="layui-row">
        <div class="layui-col-xs-offset4">
            <div id="dice" class="dice dice_1 sezi3"></div>
        </div>
    </div>
    <div class="layui-row">
        <div class="layui-col-xs8">
            <div id="dice" class="dice dice_1 sezi4"></div>
        </div>
        <div class="layui-col-xs4">
            <div id="dice" class="dice dice_1 sezi5"></div>
        </div>
    </div>
    <div class="layui-row">
        <div class="layui-col-xs-offset4">
           <button id="btnAll" class="layui-btn layui-btn-danger">一键全部摇</button>
        </div>
    </div>
</div>

<!--定义全局变量-->
<script>
    var SHAKE_THRESHOLD = 4500;  //定义触发动作的阈值
    var last_update = 0;         //上一次触发的时间
    var x = y = z = last_x = last_y = last_z = 0;//x,y,z当前加速度,last_z,last_x,last_y上次加速度<span style="font-size:18px;"></span>
    var isJumping = false;
</script>

<!--摇一摇内置脚本-->
<script>    
    function deviceMotionHandler(eventData) {
        var acceleration = eventData.accelerationIncludingGravity;
        var curTime = new Date().getTime();
        if ((curTime - last_update) > 100) {
            var diffTime = curTime - last_update;
            last_update = curTime;
            x = acceleration.x;
            y = acceleration.y;
            z = acceleration.z;
            var speed = Math.abs(x + y + z - last_x - last_y - last_z) / diffTime * 10000;
           
            if (speed > SHAKE_THRESHOLD) {
                //alert("speed:"+speed);
                //alert("SHAKE_THRESHOLD" + SHAKE_THRESHOLD);
                //摇动成功触发这个函数
                handelShakingMotion();              
            }
            last_x = x;
            last_y = y;
            last_z = z;
        }
    }
    //监听摇一摇的动作
    function listenPhoneShake() {
        if (window.DeviceMotionEvent) {
            window.addEventListener('devicemotion', deviceMotionHandler, false);
            console.log("addEventListener devicemotion");
        } else {
            alert('抱歉，你的手机配置实在有些过不去，考虑换个新的再来试试吧');
        }
    }
</script>

<!--自定义脚本-->
<script type="text/javascript">
    //摇动后执行的事件
    function handelShakingMotion() {
        if (isJumping) return;
        $('#shakingAudio').get(0).play();
        isJumping = true;
        startJump(0);
        startJump(1);
        startJump(2);
        startJump(3);
        startJump(4);
    }

    //初始化
    $(function () {
        listenPhoneShake();
        //处理iphone不能自动播放  
        document.addEventListener('WeixinJSBridgeReady', function () {
            $('#shakingAudio').get(0).play();
        }, false);

      
        $("#btnAll").click(function () {
            //一般android机都能自动播放  
            $('#shakingAudio').get(0).play();          
            startJump(0);
            startJump(1);
            startJump(2);
            startJump(3);
            startJump(4);
        })
    });

    //色子摇动特效,设置点数
    function startJump(index) {
        var dice = $(".dice").eq(index);
        $(".wrap").append("<div id='dice_mask'></div>");//加遮罩
        dice.attr("class", "dice");//清除上次动画后的点数
        dice.css('cursor', 'default');
        var num = Math.floor(Math.random() * 6 + 1);//产生随机数1-6
        dice.animate({ left: '+2px' }, 100, function () {
            dice.addClass("dice_t");
        }).delay(200).animate({ top: '-2px' }, 100, function () {
            dice.removeClass("dice_t").addClass("dice_s");
        }).delay(200).animate({ opacity: 'show' }, 600, function () {

                isJumping = false;
            }
        });

</script>

自定义手机摇色子就完成了，部署到自己的服务器上就可以使用了
