+#  井字过三关小游戏
+
+### 简介
+
+Demo基于Open Harmony系统使用ETS语言进行编写，本Demo主要通过设备认证、，分布式拉起，分布式数据管理等功能来实现。
+
+1. ##### 设备认证
+
+   陌生设备开始游戏前需要进行设备认证，使用[DeviceManager](https://gitee.com/openharmony/device_manager)组件，DeviceManager组件在OpenHarmony上提供账号无关的分布式设备的认证组网能力，并为开发者提供了一套用于分布式设备间监听、发现和认证的接口。
+
+2. ##### 分布式拉起
+
+   通过使用[FeatureAbility](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/apis/js-apis-featureAbility.md)模块的startAbility接口，远程拉起其他在线设备。
+
+3. ##### 分布式数据管理
+
+   使用[distributedData](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/apis/js-apis-distributed-data.md)模块同步设备之间的数据。
+
+
+
+### 快速上手
+
+#### 1. Hi3516环境准备
+
+- 获取Open Harmony源代码，OpenHarmony版本须3.0LTS以上，参考[源码下载](https://www.openharmony.cn/pages/extra/70a9ad/)
+- 搭建Linux基础环境，安装编译依赖基础软件，参考[安装开发板环境](https://www.openharmony.cn/pages/0001000400/#%E5%B0%86linux-shell%E6%94%B9%E4%B8%BAbash)
+- 编译以及烧录，参考[开发板（编译、烧录）](https://www.openharmony.cn/pages/0001000401/#%E6%96%B0%E5%BB%BA%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F)
+
+#### 2. 应用编译环境准备
+
+- 下载DevEco Studio 3.0.0.601及以上版本 [下载地址](https://developer.harmonyos.com/cn/develop/deveco-studio#download_beta)
+- 配置SDK，参考 [配置OpenHarmony-SDK](https://www.openharmony.cn/pages/00090001/#%E5%89%8D%E6%8F%90%E6%9D%A1%E4%BB%B6)
+- DevEco Studio 点击File -> Open 导入本工程
+
+#### 3. 安装应用
+
+- 对应用进行签名，可以参考[配置OpenHarmony应用签名信息](https://www.openharmony.cn/pages/00090003/#%E7%94%9F%E6%88%90%E5%AF%86%E9%92%A5%E5%92%8C%E8%AF%81%E4%B9%A6%E8%AF%B7%E6%B1%82%E6%96%87%E4%BB%B6)
+
+- 安装应用
+
+  打开**OpenHarmony SDK路径 \toolchains** 文件夹下，执行如下hdc_std命令，其中**path**为hap包所在路径。
+
+  ```
+  hdc_std file install path\entry-debug-standard-ark-signed.hap
+  ```
+
+  
+
+### 应用效果
+
+1. ##### 设备认证,开始游戏前，如果是陌生设备需要先通过认证
+
+ ![deviceAuthentication](./resource/deviceAuthentication.gif)
+
+2. ##### 开始游戏,如果设备之前认证过了，可以直接开始游戏
+
+ ![startGame](./resource/startGame.gif)
+
+#### 如何体验
+
+##### 1. 将所有设备连入同一局域网
+
+##### 2. 应用内点击开始游戏进行设备认证，并拉起远程设备端应用
+

+# 井字过三关小游戏
+
+### 简介
+
+Demo基于Open Harmony系统使用ETS语言进行编写，本Demo主要通过设备认证、分布式拉起、分布式数据管理等功能来实现。
+
+
+
+#### 应用效果
+
+1. ##### 设备认证,开始游戏前，如果是陌生设备需要先通过认证
+
+&nbsp;![deviceAuthentication](./resource/deviceAuthentication.gif)
+
+2. ##### 开始游戏,如果设备之前认证过了，可以直接开始游戏
+
+&nbsp;![startGame](./resource/startGame.gif)
+
+
+
+
+
+### 开发步骤
+
+#### 1.新建Openharmony ETS工程
+
+在DevEco Studio中点击File -> New Project ->[Standard]Empty Ability->Next，Language 选择ETS语言，最后点击Finish即创建成功。

+                      this.startDialog.open()
+                    })
+                  Text("").height(20)
+                  Text('游戏规则').fontSize(20).fontColor('#FF00FF').height(60).decoration({ type: TextDecorationType.Underline, color: Color.Red }).onClick(() => {
+                      this.rulesDialog.open()
+                    })
+                }.height('40%')
+              }
+            }
+          }.height('50%').width('90%')
+
+          Flex() {

+        }
+      }
+    }.width('100%').height('100%')
+  }
+```
+
+
+
+自定义弹窗
+
+1.点击开始按钮的弹窗如下图所示,窗口从上到下由[Text](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/ts-based-declarative-development-paradigm/ts-basic-components-text.md),[List](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/ts-based-declarative-development-paradigm/ts-container-list.md)，[Button](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/ts-based-declarative-development-paradigm/ts-basic-components-button.md)组成，List中的子元素由Text和Radio组成，以下代码的省略号表示非UI相关的逻辑代码，具体实现参考源代码
+
+&nbsp;![3](./resource/3.png)
+
+```
+@CustomDialog
+struct gameStart {
+  build() {
+    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
+      Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
+        //顶部标题
+        Text('发现以下在线设备').fontColor(Color.Black).fontSize(30)
+      }.width('100%').height('20%')
+
+      Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Start }) {
+       //使用List容器动态加载在线设备
+       List() {
+          ForEach(this.deviceName, (item) => {
+            ListItem() {
+              Row() {
+                //Text组件显示设备名
+                Text(item.deviceName).width('80%').fontSize(30).fontColor(Color.Black)
+                //Radio组件显示单选框
+                Radio({ value: '' }).checked(this.check[item.id]).onChange(() => {
+                  //这里保证List里面点击了多个Radio组件时，只有当前点击的为选中状态
+                  for (let i = 0; i < this.check.length; i++) {
+                    this.check[i] = false
+                  }
+                  this.check[item.id] = true
+                })
+              }
+            }
+          }, item => item.id)
+        }
+        .height('80%')
+
+        Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
+          Button('确定').width(200).height(50).fontSize(30).onClick(() => {
+          	//......
+            this.controller.close()
+          })
+        }.height('30%')
+
+      }.width('100%').height('80%')
+    }.height('100%').width('100%')
+  }
+}
+```
+
+
+
+点击游戏规则的弹窗由Text，Text，button组成，具体实现可以参考弹窗1，和源代码
+
+
+
+##### 2） 棋盘界面
+
+&nbsp;![4](./resource/4.png)
+
+
+
+棋盘界面由状态栏（左上图标表示当前由X或者O执行，右上表示自己本局使用X或者O），九宫格棋盘（[Grid](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/ts-based-declarative-development-paradigm/ts-container-grid.md)组件绘制），button按钮组成。
+
+```
+build() {
+    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
+      Row({ useAlign: HorizontalAlign.Start }) {
+      //左上图标
+        if (this.selfChess === EMPTY) {
+          Image(this.current_X).height(150).width('30%')
+        } else if (this.curChess === CIRCLE) {

+        } else {
+          Image(this.selfChess === FORK ? this.self_X : this.self_O).height(150).width('30%')
+        }
+      }.height('30%')
+      Flex() {

+          })
+      }.height('20%')
+    }
+  }
+```
+
+
+
+#### 3.设备认证
+
+设备认证是依赖[DeviceManager](https://gitee.com/openharmony/device_manager)组件来实现的，详细代码参考源码RemoteDeviceModel.ets
+
+1.创建DeviceManager实例
+
+```
+ registerDeviceListCallback(callback) {
+    if (typeof (this.#deviceManager) === 'undefined') {
+      deviceManager.createDeviceManager('com.example.tictactoegame', (error, value) => {
+        if (error) return
+        this.#deviceManager = value;
+        this.registerDeviceListCallback_(callback);
+      });
+    } else {
+      this.registerDeviceListCallback_(callback);
+    }
+  }
+```
+
+2.查询可信设备列表
+
+```
+ var list = this.#deviceManager.getTrustedDeviceListSync();
+    if (typeof (list) != 'undefined' && typeof (list.length) != 'undefined') {
+      this.deviceList = list;
+    }
+```
+
+3.注册设备上下线监听
+
+```
+this.#deviceManager.on('deviceStateChange', (data) => {
+      switch (data.action) {
+        case 0:
+          this.deviceList[this.deviceList.length] = data.device;
+          this.callback();
+          if (this.authCallback != null) {
+            this.authCallback();
+            this.authCallback = null;
+          }
+          break;
+        case 2:
+          if (this.deviceList.length > 0) {
+            for (var i = 0; i < this.deviceList.length; i++) {
+              if (this.deviceList[i].deviceId === data.device.deviceId) {
+                this.deviceList[i] = data.device;
+                break;
+              }
+            }
+          }
+          this.callback();
+          break;
+        case 1:
+          if (this.deviceList.length > 0) {
+            var list = [];
+            for (var i = 0; i < this.deviceList.length; i++) {
+              if (this.deviceList[i].deviceId != data.device.deviceId) {
+                list[i] = data.device;
+              }
+            }
+            this.deviceList = list;
+          }
+          this.callback();
+          break;
+        default:
+          break;
+      }
+    });
+```
+
+4.设备发现
+
+```
+this.#deviceManager.on('deviceFound', (data) => {
+      for (let i = 0; i < this.discoverList.length; i++) {
+        if (that.discoverList[i].deviceId === data.device.deviceId) {
+          return;
+        }
+      }
+      this.discoverList[this.discoverList.length] = data.device;
+      this.callback();
+    });
+```
+
+5.设备认证
+
+```
+authDevice(deviceInfo, callback){
+    let extraInfo = {
+      "targetPkgName": 'com.example.tictactoegame',
+      "appName": 'com.example.tictactoegame',
+      "appDescription": 'com.example.tictactoegame',
+      "business": '0'
+    };
+    let authParam = {
+      "authType": 1,
+      "appIcon": '',
+      "appThumbnail": '',
+      "extraInfo": extraInfo
+    };
+    this.#deviceManager.authenticateDevice(deviceInfo, authParam, (err, data) => {
+      if (err) {
+        this.authCallback = null;
+      } else {
+        this.authCallback = callback;
+      }
+    });
+  }
+```
+
+#### 4.数据管理
+
+[分布式数据管理](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/apis/js-apis-distributed-data.md)依赖@ohos.data.distributedData模块实现，详细参考源码RemoteDataManager.ets
+
+1.导入该模块
+
+```
+import factory from '@ohos.data.distributedData';
+```
+
+2.创建KVManager实例，用于管理数据库对象
+
+```
+  registerDataListCallback(callback) {
+    let that = this
+    if (this.kvManager == null) {
+      try {
+        const config = {
+          userInfo: {
+            userId: '0',
+            userType: 0
+          },
+          bundleName: 'com.example.tictactoegame'
+        }
+        factory.createKVManager(config).then((manager) => {
+          that.kvManager = manager
+          that.registerDataListCallback_(callback)
+        }).catch((err) => {
+        })
+      } catch (e) {
+      }
+    } else {
+      this.registerDataListCallback_(callback)
+    }
+  }
+```
+
+3.创建并获取KVStore数据库
+
+```
+registerDataListCallback_(callback) {
+    let that = this
+    if (that.kvManager == null) {
+      callback()
+      return
+    }
+    if (that.kvStore == null) {
+      try {
+        let options =
+          {
+            createIfMissing: true,
+            encrypt: false,
+            backup: false,
+            autoSync: true,
+            kvStoreType: 1,
+            securityLevel: 3
+          }
+        this.kvManager.getKVStore(this.STORE_ID, options).then((store) => {
+          that.kvStore = store
+          that._registerDataListCallback_(callback)
+        }).catch((err) => {
+        })
+      } catch (e) {
+      }
+    } else {
+      this._registerDataListCallback_(callback)
+    }
+  }
+```
+
+4.订阅指定类型的数据变更通知
+
+```
+  _registerDataListCallback_(callback) {
+    let that = this
+    if (that.kvManager == null) {
+      callback()
+      return
+    }
+    this.kvStore.on('dataChange', 1, function(data) {
+      if (data) {
+         that.arr = data.updateEntries
+        callback()
+      }
+    })
+  }
+```
+
+5.添加指定类型键值对到数据库
+
+```
+  dataChange(key, value) {
+    let that = this
+      try {
+        that.kvStore.put(JSON.stringify(key), JSON.stringify(value)).then((data) => {
+        }).catch((err) => {
+          prompt.showToast({message:'put err:'+JSON.stringify(value)})
+        })
+
+      } catch (e) {
+      }
+  }
+```
+
+
+
+#### 5.远程拉起设备app
+
+使用[FeatureAbility](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/js-reference/apis/js-apis-featureAbility.md)模块的startAbility接口拉起远程设备app
+
+```
+  startAbilityContinuation(deviceId) {
+    let wantValue = {
+      bundleName: 'com.example.tictactoegame',
+      abilityName: 'com.example.tictactoegame.MainAbility',
+      deviceId: deviceId,
+      parameters: {
+        uri: 'pages/Fight'
+      }
+    };
+    featureAbility.startAbility({ want: wantValue }).then(() => {
+      router.replace({ uri: 'pages/Fight' })
+    });
+  }
+```
+
+
+
+#### 6.棋局胜负判定
+
+对于棋盘中的任一个格子只存在已落子和未落子两种状态，我们把这两种状态定义为1和0，则九宫格可以看成是一个只有9位的二进制数，胜利状态有八种情况如下，详细代码参考源码Chess.ets：
+
+```
+0b111000000
+0b100100100
+0b100010001
+0b010010010
+0b001001001
+0b000111000
+0b000000111
+0b001010100
+```
+
+胜负判定实现如下
+
+```
+  isWin() {
+    let x = this.result_X
+    let o = this.result_O
+    if (448 == (x & 448) || 292 == (x & 292) || 273 == (x & 273) || 146 == (x & 146) || 73 == (x & 73) || 56 == (x & 56) || 7 == (x & 7) || 84 == (x & 84)){
+      this.allIsTrue()
+      return FORK
+    }
+    if (448 == (o & 448) || 292 == (o & 292) || 273 == (o & 273) || 146 == (o & 146) || 73 == (o & 73) || 56 == (o & 56) || 7 == (o & 7) || 84 == (o & 84)) {
+      this.allIsTrue()
+      return CIRCLE
+    }
+    let res = 0;
+    for (let i = 0; i < 9; i++) {
+      if (this.used[i] == false) {
+        res = 1
+        break
