摇骰子设计与实现
手机摇一摇可以摇骰子，上划可查看结果，震动加声音等功能。
本章底部会贴出所有代码，图片资源以及音频资源很简单，自己找一下就行了。
已经上线小程序，可以扫码直接预览效果。
准备工作
新建一个项目，将已经准备好的资源，放入到项目中。下面是需要资源图片的示例。
实现步骤以及思路
作为一个前端，看到东西总是想着去实现一下。感觉摇骰子简单就实现一下，如果难的话，可能就不会出来了。哈哈，开始上正文。
首先开始思考摇骰子的流程，准备状态>>>晃动中状态>>>等待开起状态>>>开启后状态。
简单的四步循环，开整。
第一步：实现准备状态
实现准备状态，我们要实现什么？
1、手机摇一摇后开始摇骰子
开整，页面如何铺设就不描述了代码在最下面。
利用uni.onGyroscopeChange监听陀螺仪，根据陀螺仪变化的速率来判断是否摇动了手机，当检测到摇动手机号开始游戏，并停止监听陀螺仪。
实际情况中发现，摇动幅度大持续时间长，会执行多次。这里我想的是加个shakeState变量，监听到一次的时候就改变 shakeState，然后停止监听后开始游戏。
//监听陀螺仪
start() {
uni.onGyroscopeChange((res) => {
var nowRange = Math.abs(res.x) + Math.abs(res.x) + Math.abs(res.x);
if (nowRange > 10) {
this.shakeState = true
}
if(this.shakeState){
this.stop()
this.shakeState = false
this.playGame()
}
});
uni.startGyroscope({
interval: "normal"
})
},
//停止监听陀螺仪
stop() {
uni.stopGyroscope({})
},
第二步：实现晃动中状态
实现晃动中状态，我们要实现什么？
1、整个骰盅晃动，发出摇骰子的声音
骰盅晃动是通过vue中的**:class类样式绑定，在代码中写了一个rollDiceAnimation**的样式类实现一个动画，然后判断“gameType”的变量实现动画。
<view class="diceCountent" :class="{'rollDiceAnimation':gameType == 1}">
</view>
声音的是利用了“uni.createInnerAudioContext()”设置好自动播放，音频文件地址，调用**onPlay()**方法实现声音的播放。
const innerAudioContext = uni.createInnerAudioContext();
innerAudioContext.autoplay = true;
innerAudioContext.src = '/static/rollDice/dice.mp3';
innerAudioContext.onPlay(() => {});
第三步：等待开起状态
实现晃动中状态，我们要实现什么？
1、上划骰盅晃动，展示结果。
实现滑动，这里就不得不说下手指触摸屏幕**“@touchstart”、触摸移动“@touchmove”、手指离开屏幕“@touchend”这个三个事件。手指触摸的时候记录当前pageY**的值，移动时算出移动的位置，改变骰盅的位置。手指离开后恢复原先的状态。
原本想着，滑动骰盅直接展示结果，但是感觉太突然了。就使用“opacity”透明度显得不那么突然。
<image class="maskbox" v-show="gameType != 3" :style="{'transform':'translate3d(0px,-'+yMove+'px,0)'}"
@touchstart="maskTouchStart" @touchmove.prevent="maskTouchMove" @touchend="maskTouchEnd"
src="../../static/rollDice/dice.png" mode=""></image>
// 开始触摸屏幕
maskTouchStart(ev) {
this.YStart = ev.changedTouches[0].pageY
},
// 触摸移动
maskTouchMove(ev) {
var result =0
if(this.gameType == 2){
result = parseInt(this.YStart - ev.changedTouches[0].pageY)
}
if(result > 0){
this.yMove = result
this.opacityShow = result/100
}
},
// 触摸结束
maskTouchEnd(ev) {
this.yMove = 0
this.opacityShow = 0
},
第四步：开启后状态
开启后状态，我们要实现什么？
1、结果骰子的展示。
毕竟6个骰子和20个骰子展示是不一样的。这里先定好要展示位置的大小，然后通过骰子的个数，来改变骰子图片的大小
// 设置骰子位置前
setDice() {
var arr = []
// 生成坐标数组
if (this.diceCount > 9) {
let pointSum = Math.floor(Math.sqrt(this.diceCount)) + 1
this.diceWidth = parseInt(240 / pointSum)
for (let i = 0; i < pointSum; i++) {
for (let k = 0; k < pointSum; k++) {
arr[arr.length] = {
top: i * this.diceWidth,
left: k * this.diceWidth
}
}
}
} else {
for (let i = 0; i < 3; i++) {
for (let k = 0; k < 3; k++) {
arr[arr.length] = {
top: i * 80,
left: k * 80
}
}
}
}
// 骰子位置以及角度
var dice, angle, temp, tempList
for (var i = 0; i < this.diceCount; i++) {
dice = (Math.random() * 6) >> 0
angle = (Math.random() * 6) >> 0
temp = (Math.random() * arr.length) >> 0;
// 让数组不重复
tempList = arr[temp];
arr.splice(temp, 1)
this.addDiceList(dice, angle, tempList)
}
},
// 设置骰子
addDiceList(dice, angle, tempList) {
this.diceList.push({
"rotate": 30 * angle,
"dice": dice,
"top": tempList.top,
"left": tempList.left
})
},
部分优化
总体的功能就实现了，为了更加完善。设置弹框、历史开骰记录、准备状态下显示骰子数量、等待开起状态开始陀螺仪监听可继续摇。这就不多说了，具体的逻辑代码都在下面。文章来源：https://www.toymoban.com/news/detail-663663.html
