1. 添加顶部功能栏

定义状态变量time并初始化为0，用于记录当前的时间值。定义状态变量mine，调用router.getParams().difficulty来获取到页面跳转来时携带的difficulty对应的数据，即地雷总数，其中同样需要导入router模块。
定义全局变量timeoutID，添加一个名为initialize()的函数通过setInterval()对timeoutID进行初始化为定时器，用于逐秒对time进行递增。在自定义组件的生命周期函数aboutToAppear()中调用函数initialize()。
在菜单按钮组件的点击事件中清除定时器并通过router.back()返回到主页面。
game.ets:

import router from '@system.router'

var timeoutID;

@Entry
@Component
struct Game {
  @State time: number = 0
  @State mine: number = router.getParams().difficulty

  aboutToAppear(){
    this.initialize()
  }

  initialize(){
    timeoutID = setInterval(() =>{
      this.time += 1
    }, 1000);
  }

  build() {
    Column(){
      Row() {
        Button('菜 单', { type: ButtonType.Normal, stateEffect: true })
          .width(95)
          .height(50)
          .borderRadius(8)
          .borderColor('#6379A8')
          .borderWidth(2)
          .fontSize(26)
          .fontWeight(700)
          .fontColor('#1E2B46')
          .backgroundColor('#C1D0E6')
          .margin({ left:10, top: 2 })
          .onClick(() => {
            clearInterval(timeoutID)
            router.back()
          })
        setImage({ str: 'time.png' })
        setText({ num: $time })
        setImage({ str: 'lei.png' })
        setText({ num: $mine })
      }
      .width('100%')
      .height(60)
      .backgroundColor('#C1D0E6')
      .margin({ top: 80 })

    }
    .width('100%')
    .height('100%')
    .backgroundColor('#D6DDE7')
  }
}

@Component
struct setImage {
  private str: string

  build() {
    Image($rawfile(this.str))
      .height(50)
      .width(50)
      .scale({ x: 0.9, y: 0.9 })
      .margin({ left:10, top: 3 })
  }
}

@Component
struct setText {
  @Link num: number

  build() {
    Text(this.num.toString())
      .width(60)
      .height(30)
      .borderRadius(10)
      .borderColor('#4162AA')
      .borderWidth(1)
      .fontSize(26)
      .textAlign(TextAlign.Center)
      .fontWeight(700)
      .fontColor('#FFFFFF')
      .backgroundColor('#4162AA')
      .margin({ left:3, top: 5 })
      .padding(0)
  }
}

2. 实现扫雷主体

定义变量row和column，调用router.getParams().Number_row和router.getParams().Number_column来获取到页面跳转来时携带的数据，即网格行数和网格列数。定义状态变量Number_row和Number_column并初始化为1~9的字符数组。定义状态变量statesGrids并初始化为16x16全为0的二维数组，用于记录网格中对应位置格子的状态。定义状态变量isCountDown并初始化为true，用于刷新页面组件状态。
在自定义组件的生命周期函数aboutToAppear()中根据row和column的值对Number_row和Number_column进行更新。
在函数initialize()中随机将地雷放置到网格中，即对应位置的grids置为-1，其余非-1的格子对应的位置放置该格子周围的地雷数量。
添加一个名为estimatemine(i, j)的函数用于翻开该格子周围非地雷的格子。
在容器Grid中通过两个循环渲染ForEach对网格进行绘制，在每一个格子中，若对应位置的statesGrids为1，则表示翻开状态，若对应位置的statesGrids为0，则表示没翻开状态。在翻开状态中，若对应位置的grids为-1，则表示是地雷，否则表示该格子周围地雷的数量。在每个格子的点击事件中，若若对应位置的statesGrids为0，则置为1，若对应位置的grids为0，则调用函数estimatemine(i, j)。最后对isCountDown进行取反，用于刷新页面组件状态。

      .backgroundColor('#4162AA')
      .margin({ left:3, top: 5 })
      .padding(0)
  }
}

3. 实现插旗功能

定义状态变量statesBtn并初始化为1，用于记录当前响应的是哪个按钮，当为1时表示响应翻开按钮的功能，当为0时表示响应插旗按钮的功能。
在容器Grid的每个按钮中，增加对statesBtn的判断以响应相应的按钮功能，当为插旗功能时，当对应位置的statesGrids为2则表示为旗子，当对应位置的statesGrids为3时则表示“？”。在点击事件中增加对statesBtn的判断以响应相应的按钮功能，当为插旗功能时，实现对应位置的statesGrids在0、2、3之间轮换，即没有翻开状态、旗子状态、问号状态。

4. 实现自定义弹窗和重新开始

定义状态变量success和over并初始化为false和true，用于记录游戏是否成功和游戏是否失败，当success为true时表示游戏成功，当over为false时表示游戏失败。
添加名为gamesuccess()和gameover()用于判断游戏是否成功和游戏是否失败。
使用装饰器@CustomDialog自定义弹窗界面。
在函数initialize()的定时器中对success和over进行实时更新，并且当游戏成功或游戏失败时停止定时器和通过open()启动自定义弹窗界面。
在容器Grid的按钮组件的点击事件中增加判断，当游戏没有成功或游戏没有失败时才响应点击事件。
在重新开始按钮的点击事件中对所有变量进行初始化，并且调用函数initialize()。
