1.2 安装DevEco Studio详细步骤

DevEco Studio是HarmonyOS官方集成开发环境,以下是安装的完整流程:

// 环境验证脚本
import { SystemInfo, FileSystem } from '@ohos.system';

class DevelopmentEnvironment {
  static async validate(): Promise<EnvironmentStatus> {
    const results = {
      system: await this.checkSystemRequirements(),
      storage: await this.checkStorageSpace(),
      dependencies: await this.checkDependencies()
    };
    
    return {
      passed: results.system && results.storage && results.dependencies,
      details: results
    };
  }
  
  private static async checkSystemRequirements(): Promise<boolean> {
    const info = await SystemInfo.getBasicInfo();
    const minRAM = 8 * 1024 * 1024 * 1024; // 8GB in bytes
    
    return info.ram >= minRAM && 
           (info.os.includes('Windows 10') || info.os.includes('macOS'));
  }
}

安装步骤:

  1. 访问华为开发者联盟官网(developer.huawei.com),下载DevEco Studio 5.0安装包

二、游戏架构设计:构建可扩展的游戏框架

2.1 游戏引擎架构设计

一个良好的游戏架构是项目成功的关键。我们采用分层架构设计:

RunnerGame/
├── Core/           # 游戏核心模块
│   ├── GameEngine.ets    # 游戏主引擎
│   ├── SceneManager.ets  # 场景管理器
│   └── ResourceManager.ets # 资源管理器
├── Entities/       # 游戏实体
│   ├── Player.ets       # 玩家角色
│   ├── Obstacle.ets     # 障碍物
│   └── Collectible.ets  # 可收集物品
├── Scenes/         # 游戏场景
│   ├── MainMenu.ets    # 主菜单
│   ├── GameScene.ets   # 游戏主场景
│   └── GameOver.ets    # 游戏结束场景
└── UI/             # 用户界面
    ├── HUD.ets         # 游戏内UI
    └── MenuUI.ets      # 菜单UI

2.2 游戏主引擎实现

// Core/GameEngine.ets - 游戏主引擎
@Observed
class GameEngine {
  private static instance: GameEngine;
  private gameState: GameState = GameState.MENU;
  private currentScene: BaseScene;
  private renderer: GameRenderer;
  private inputManager: InputManager;
  private physicsEngine: PhysicsEngine2D;
  
  // 单例模式确保全局唯一实例
  static getInstance(): GameEngine {
    if (!GameEngine.instance) {
      GameEngine.instance = new GameEngine();
    }
    return GameEngine.instance;
  }
  
  private constructor() {
    this.initializeSystems();
  }
  
  // 初始化所有子系统
  private initializeSystems(): void {
    this.renderer = new GameRenderer();
    this.inputManager = new InputManager();
    this.physicsEngine = new PhysicsEngine2D();
    
    // 设置游戏循环
    this.setupGameLoop();
  }
  
  // 游戏主循环
  private setupGameLoop(): void {
    const gameLoop = () => {
      const startTime = Date.now();
      
      // 处理输入
      this.inputManager.processInput();
      
      // 更新游戏逻辑
      this.update();
      
      // 物理模拟
      this.physicsEngine.simulate();
      
      // 渲染
      this.renderer.render();
      
      // 控制帧率
      const frameTime = Date.now() - startTime;
      const targetFrameTime = 1000 / 60; // 60fps
      
      if (frameTime < targetFrameTime) {
        setTimeout(gameLoop, targetFrameTime - frameTime);
      } else {
        requestAnimationFrame(gameLoop);
      }
    };
    
    gameLoop();
  }
  
  // 更新游戏状态
  private update(): void {
    if (this.currentScene) {
      this.currentScene.update();
    }
    
    // 检查游戏状态转换
    this.checkStateTransition();
  }
  
  // 切换游戏场景
  changeScene(sceneType: SceneType): void {
    if (this.currentScene) {
      this.currentScene.cleanup();
    }
    
    this.currentScene = SceneFactory.createScene(sceneType);
    this.currentScene.initialize();
  }
}

2.3 游戏状态管理

// Core/GameStateManager.ets
enum GameState {
  MENU = 'menu',
  PLAYING = 'playing',
  PAUSED = 'paused',
  GAME_OVER = 'game_over',
  LEVEL_COMPLETE = 'level_complete'
}

class GameStateManager {
  private currentState: GameState = GameState.MENU;
  private score: number = 0;
  private highScore: number = 0;
  private currentLevel: number = 1;
  
  // 状态转换
  transitionTo(newState: GameState): void {
    const oldState = this.currentState;
    this.currentState = newState;
    
    // 触发状态变化事件
    this.onStateChanged(oldState, newState);
    
    // 执行状态进入逻辑
    this.executeStateEntryLogic(newState);
  }
  
  // 增加分数
  addScore(points: number): void {
    this.score += points;
    
    if (this.score > this.highScore) {
      this.highScore = this.score;
      this.saveHighScore();
    }
    
    // 分数变化事件
    EventBus.emit('score_changed', {
      score: this.score,
      highScore: this.highScore
    });
  }
  
  // 保存游戏进度
  async saveGameProgress(): Promise<void> {
    const progress: GameProgress = {
      score: this.score,
      level: this.currentLevel,
      timestamp: Date.now()
    };
    
    try {
      await Preferences.set('game_progress', JSON.stringify(progress));
    } catch (error) {
      console.error('保存游戏进度失败:', error);
    }
  }
}

三、游戏角色与实体实现

3.1 玩家角色实现

// Entities/Player.ets - 玩家角色
@Component
struct Player extends GameEntity {
  @State position: Vector2 = { x: 100, y: 300 };
  @State velocity: Vector2 = { x: 0, y: 0 };
  @State isJumping: boolean = false;
  @State health: number = 100;
  @State animationState: AnimationState = AnimationState.RUNNING;
  
  private jumpForce: number = -15;
  private gravity: number = 0.5;
  private groundLevel: number = 300;
  private moveSpeed: number = 5;
  
  build() {
    // 玩家角色渲染
    Image($r('app.media.player_run'))
      .width(80)
      .height(80)
      .position({ x: this.position.x, y: this.position.y })
      .animation(this.getCurrentAnimation())
  }
  
  // 处理玩家输入
  handleInput(input: GameInput): void {
    switch (input.type) {
      case 'jump':
        if (!this.isJumping) {
          this.jump();
        }
        break;
      case 'slide':
        this.slide();
        break;
      case 'move_left':
        this.moveLeft();
        break;
      case 'move_right':
        this.moveRight();
        break;
    }
  }
  
  // 跳跃逻辑
  private jump(): void {
    this.velocity.y = this.jumpForce;
    this.isJumping = true;
    this.animationState = AnimationState.JUMPING;
    
    // 播放跳跃音效
    AudioManager.playSound('jump');
  }
  
  // 更新玩家状态
  update(): void {
    // 应用重力
    this.velocity.y += this.gravity;
    
    // 更新位置
    this.position.x += this.velocity.x;
    this.position.y += this.velocity.y;
    
    // 地面检测
    if (this.position.y >= this.groundLevel) {
      this.position.y = this.groundLevel;
      this.velocity.y = 0;
      this.isJumping = false;
      
      if (this.animationState === AnimationState.JUMPING) {
        this.animationState = AnimationState.RUNNING;
      }
    }
    
    // 边界检测
    this.checkBoundaries();
  }
  
  // 碰撞检测
  checkCollision(other: GameEntity): boolean {
    const playerRect = this.getBoundingBox();
    const otherRect = other.getBoundingBox();
    
    return this.rectIntersect(playerRect, otherRect);
  }
}

3.2 障碍物系统

// Entities/Obstacle.ets - 障碍物
class Obstacle extends GameEntity {
  private type: ObstacleType;
  private speed: number;
  private damage: number;
  
  constructor(type: ObstacleType, position: Vector2) {
    super();
    this.type = type;
    this.position = position;
    this.initializeFromType();
  }
  
  private initializeFromType(): void {
    switch (this.type) {
      case ObstacleType.SPIKE:
        this.speed = 3;
        this.damage = 20;
        this.width = 40;
        this.height = 40;
        break;
      case ObstacleType.ROCK:
        this.speed = 2;
        this.damage = 30;
        this.width = 60;
        this.height = 60;
        break;
      case ObstacleType.GAP:
        this.speed = 4;
        this.damage = 100; // 掉落即死亡
        this.width = 120;
        this.height = 200;
        break;
    }
  }
  
  update(): void {
    // 向左移动(玩家向右跑)
    this.position.x -= this.speed;
    
    // 移出屏幕后回收
    if (this.position.x < -100) {
      this.recycle();
    }
  }
  
  // 对象池回收
  recycle(): void {
    ObstaclePool.returnObstacle(this);
  }
}

// 障碍物对象池
class ObstaclePool {
  private static pools: Map<ObstacleType, Obstacle[]> = new Map();
  
  static getObstacle(type: ObstacleType, position: Vector2): Obstacle {
    let pool = this.pools.get(type);
    
    if (!pool) {
      pool = [];
      this.pools.set(type, pool);
    }
    
    if (pool.length > 0) {
      const obstacle = pool.pop()!;
      obstacle.position = position;
      obstacle.reset();
      return obstacle;
    }
    
    return new Obstacle(type, position);
  }
  
  static returnObstacle(obstacle: Obstacle): void {
    const pool = this.pools.get(obstacle.type);
    if (pool && pool.length < 50) { // 限制池大小
      pool.push(obstacle);
    }
  }
}

四、游戏场景与关卡设计

4.1 游戏主场景实现

// Scenes/GameScene.ets - 游戏主场景
@Component
struct GameScene extends BaseScene {
  @State player: Player = new Player();
  @State obstacles: Obstacle[] = [];
  @State collectibles: Collectible[] = [];
  @State background: BackgroundManager;
  @State score: number = 0;
  @State distance: number = 0;
  
  private obstacleSpawnTimer: number = 0;
  private obstacleSpawnInterval: number = 120; // 每120帧生成一个障碍物
  private gameSpeed: number = 1.0;
  private difficultyLevel: number = 1;
  
  build() {
    Stack({ alignContent: Alignment.TopStart }) {
      // 背景层
      this.background.render()
      
      // 游戏实体层
      ForEach(this.obstacles, (obstacle: Obstacle) => {
        obstacle.render()
      })
      
      ForEach(this.collectibles, (collectible: Collectible) => {
        collectible.render()
      })
      
      // 玩家层
      this.player.render()
      
      // UI层
      GameHUD({
        score: this.score,
        distance: this.distance,
        health: this.player.health
      })
    }
    .width('100%')
    .height('100%')
    .onKeyEvent((event: KeyEvent) => {
      this.handleKeyEvent(event);
    })
  }
  
  // 场景初始化
  initialize(): void {
    this.player = new Player();
    this.obstacles = [];
    this.collectibles = [];
    this.background = new BackgroundManager();
    this.score = 0;
    this.distance = 0;
    
    // 启动游戏循环
    this.startGameLoop();
    
    // 播放背景音乐
    AudioManager.playBackgroundMusic('game_bgm', true);
  }
  
  // 游戏主循环
  private startGameLoop(): void {
    const gameLoop = () => {
      this.update();
      requestAnimationFrame(gameLoop);
    };
    
    gameLoop();
  }
  
  // 更新游戏状态
  update(): void {
    // 更新玩家
    this.player.update();
    
    // 更新障碍物
    this.updateObstacles();
    
    // 更新可收集物品
    this.updateCollectibles();
    
    // 更新背景
    this.background.update(this.gameSpeed);
    
    // 增加距离
    this.distance += this.gameSpeed;
    
    // 生成障碍物
    this.spawnObstacles();
    
    // 生成可收集物品
    this.spawnCollectibles();
    
    // 检测碰撞
    this.checkCollisions();
    
    // 更新难度
    this.updateDifficulty();
  }
  
  // 生成障碍物
  private spawnObstacles(): void {
    this.obstacleSpawnTimer++;
    
    if (this.obstacleSpawnTimer >= this.obstacleSpawnInterval) {
      const obstacleType = this.getRandomObstacleType();
      const obstacle = ObstaclePool.getObstacle(
        obstacleType,
        { x: 800, y: this.getObstacleY(obstacleType) }
      );
      
      this.obstacles.push(obstacle);
      this.obstacleSpawnTimer = 0;
      
      // 随着游戏进行,减少生成间隔
      this.obstacleSpawnInterval = Math.max(60, 120 - this.difficultyLevel * 5);
    }
  }
  
  // 碰撞检测
  private checkCollisions(): void {
    // 玩家与障碍物碰撞
    for (const obstacle of this.obstacles) {
      if (this.player.checkCollision(obstacle)) {
        this.handlePlayerHit(obstacle);
        break;
      }
    }
    
    // 玩家与可收集物品碰撞
    for (let i = this.collectibles.length - 1; i >= 0; i--) {
      const collectible = this.collectibles[i];
      if (this.player.checkCollision(collectible)) {
        this.handleCollectibleCollection(collectible);
        this.collectibles.splice(i, 1);
      }
    }
  }
}

4.2 关卡系统设计

// Core/LevelSystem.ets - 关卡系统
class LevelSystem {
  private currentLevel: number = 1;
  private levelData: Map<number, LevelConfig> = new Map();
  private levelProgress: LevelProgress[] = [];
  
  constructor() {
    this.initializeLevels();
  }
  
  // 初始化关卡数据
  private initializeLevels(): void {
    // 关卡1:新手教学
    this.levelData.set(1, {
      id: 1,
      name: "新手训练场",
      targetDistance: 1000,
      obstacleDensity: 0.3,
      collectibleDensity: 0.5,
      speedMultiplier: 1.0,
      unlockScore: 0,
      background: 'level1_bg',
      music: 'level1_bgm'
    });
    
    // 关卡2:城市街道
    this.levelData.set(2, {
      id: 2,
      name: "城市街道",
      targetDistance: 2000,
      obstacleDensity: 0.5,
      collectibleDensity: 0.4,
      speedMultiplier: 1.2,
      unlockScore: 1000,
      background: 'level2_bg',
      music: 'level2_bgm'
    });
    
    // 关卡3:森林冒险
    this.levelData.set(3, {
      id: 3,
      name: "森林冒险",
      targetDistance: 3000,
      obstacleDensity: 0.7,
      collectibleDensity: 0.3,
      speedMultiplier: 1.5,
      unlockScore: 3000,
      background: 'level3_bg',
      music: 'level3_bgm'
    });
  }
  
  // 获取当前关卡配置
  getCurrentLevelConfig(): LevelConfig {
    const config = this.levelData.get(this.currentLevel);
    if (!config) {
      throw new Error(`关卡 ${this.currentLevel} 配置不存在`);
    }
    return config;
  }
  
  // 检查关卡完成条件
  checkLevelCompletion(distance: number, score: number): boolean {
    const config = this.getCurrentLevelConfig();
    
    if (distance >= config.targetDistance) {
      this.completeLevel(score);
      return true;
    }
    
    return false;
  }
  
  // 完成关卡
  private completeLevel(score: number): void {
    const progress: LevelProgress = {
      levelId: this.currentLevel,
      score: score,
      completionTime: Date.now(),
      stars: this.calculateStars(score)
    };
    
    this.levelProgress.push(progress);
    this.saveProgress();
    
    // 解锁下一关
    this.unlockNextLevel();
    
    // 触发关卡完成事件
    EventBus.emit('level_completed', progress);
  }
  
  // 计算星级评价
  private calculateStars(score: number): number {
    const config = this.getCurrentLevelConfig();
    const targetScore = config.targetDistance * 10; // 基础分数
    
    if (score >= targetScore * 1.5) return 3;
    if (score >= targetScore * 1.2) return 2;
    if (score >= targetScore) return 1;
    return 0;
  }
}

五、用户界面与体验优化

5.1 游戏内HUD设计

// UI/GameHUD.ets - 游戏内界面
@Component
struct GameHUD {
  @Prop score: number = 0;
  @Prop distance: number = 0;
  @Prop health: number = 100;
  @Prop coins: number = 0;
  
  build() {
    Column({ space: 10 }) {
      // 顶部状态栏
      Row({ space: 20 }) {
        // 分数显示
        HUDItem({
          icon: $r('app.media.icon_score'),
          value: this.score.toString(),
          label: '分数'
        })
        
        // 距离显示
        HUDItem({
          icon: $r('app.media.icon_distance'),
          value: `${Math.floor(this.distance)}米`,
          label: '距离'
        })
        
        // 生命值显示
        HealthBar({
          current: this.health,
          max: 100
        })
        
        // 金币显示
        HUDItem({
          icon: $r('app.media.icon_coin'),
          value: this.coins.toString(),
          label: '金币'
        })
      }
      .width('100%')
      .padding(20)
      .backgroundColor('rgba(0,0,0,0.5)')
      .borderRadius(10)
      
      // 能力图标
      AbilityIcons()
      
      // 暂停按钮
      Button('暂停', { type: ButtonType.Capsule })
        .width(80)
        .height(40)
        .position({ x: '90%', y: 20 })
        .onClick(() => {
          GameEngine.getInstance().pauseGame();
        })
    }
  }
}

// 生命值进度条组件
@Component
struct HealthBar {
  @Prop current: number = 100;
  @Prop max: number = 100;
  
  build() {
    Row() {
      // 生命值图标
      Image($r('app.media.icon_heart'))
        .width(24)
        .height(24)
        .margin({ right: 8 })
      
      // 进度条
      Stack() {
        // 背景
        Rect()
          .width(150)
          .height(12)
          .fill('#333333')
          .radius(6)
        
        // 前景(当前生命值)
        Rect()
          .width(150 * (this.current / this.max))
          .height(12)
          .fill(this.getHealthColor())
          .radius(6)
      }
      
      // 生命值文本
      Text(`${this.current}/${this.max}`)
        .fontSize(12)
        .fontColor('#FFFFFF')
        .margin({ left: 8 })
    }
  }
  
  private getHealthColor(): string {
    const percentage = this.current / this.max;
    
    if (percentage > 0.7) return '#4CAF50'; // 绿色
    if (percentage > 0.3) return '#FF9800'; // 橙色
    return '#F44336'; // 红色
  }
}

5.2 菜单系统实现

// UI/MainMenu.ets - 主菜单
@Component
struct MainMenu {
  @State selectedIndex: number = 0;
  @State menuItems: MenuItem[] = [
    { id: 'start', label: '开始游戏', icon: 'play' },
    { id: 'continue', label: '继续游戏', icon: 'resume' },
    { id: 'levels', label: '选择关卡', icon: 'level' },
    { id: 'settings', label: '游戏设置', icon: 'settings' },
    { id: 'achievements', label: '成就系统', icon: 'trophy' },
    { id: 'quit', label: '退出游戏', icon: 'exit' }
  ];
  
  build() {
    Column({ space: 0 }) {
      // 游戏标题
      Text('极速跑酷')
        .fontSize(48)
        .fontWeight(FontWeight.Bold)
        .fontColor('#FFFFFF')
        .margin({ top: 80, bottom: 60 })
      
      // 菜单列表
      List({ space: 10 }) {
        ForEach(this.menuItems, (item: MenuItem, index: number) => {
          ListItem() {
            MenuItemComponent({
              item: item,
              isSelected: index === this.selectedIndex,
              index: index
            })
          }
          .onClick(() => {
            this.handleMenuItemClick(item.id);
          })
        })
      }
      .width('80%')
      .height(400)
      .align(ListDirection.Vertical)
      
      // 版本信息
      Text('版本 1.0.0 | HarmonyOS 5.0')
        .fontSize(12)
        .fontColor('#888888')
        .margin({ top: 40 })
    }
    .width('100%')
    .height('100%')
    .backgroundImage($r('app.media.menu_bg'))
    .backgroundImageSize(ImageSize.Cover)
    .onKeyEvent((event: KeyEvent) => {
      this.handleKeyNavigation(event);
    })
  }
  
  // 处理菜单项点击
  private handleMenuItemClick(itemId: string): void {
    switch (itemId) {
      case 'start':
        GameEngine.getInstance().startNewGame();
        break;
      case 'continue':
        GameEngine.getInstance().continueGame();
        break;
      case 'levels':
        this.navigateToLevelSelection();
        break;
      case 'settings':
        this.navigateToSettings();
        break;
      case 'achievements':
        this.navigateToAchievements();
        break;
      case 'quit':
        this.quitGame();
        break;
    }
  }
  
  // 键盘导航
  private handleKeyNavigation(event: KeyEvent): void {
    if (event.type === KeyType.Down) {
      switch (event.keyCode) {
        case 10001: // 上箭头
          this.selectedIndex = Math.max(0, this.selectedIndex - 1);
          break;
        case 10002: // 下箭头
          this.selectedIndex = Math.min(this.menuItems.length - 1, this.selectedIndex + 1);
          break;
        case 10003: // 回车键
          this.handleMenuItemClick(this.menuItems[this.selectedIndex].id);
          break;
      }
    }
  }
}

六、性能优化与调试技巧

6.1 游戏性能优化策略

// Core/PerformanceOptimizer.ets
class PerformanceOptimizer {
  private frameRate: number = 0;
  private frameTimes: number[] = [];
  private memoryUsage: MemoryInfo;
  private optimizationLevel: OptimizationLevel = OptimizationLevel.BALANCED;
  
  // 性能监控
  startMonitoring(): void {
    setInterval(() => {
      this.collectPerformanceMetrics();
      this.adjustOptimizationSettings();
    }, 1000);
  }
  
  private collectPerformanceMetrics(): void {
    // 计算帧率
    this.calculateFrameRate();
    
    // 获取内存使用情况
    this.memoryUsage = SystemInfo.getMemoryInfo();
    
    // 检测性能瓶颈
    this.detectPerformanceBottlenecks();
  }
  
  // 动态调整优化设置
  private adjustOptimizationSettings(): void {
    const targetFrameRate = this.getTargetFrameRate();
    const currentFrameRate = this.frameRate;
    
    if (currentFrameRate < targetFrameRate * 0.8) {
      // 帧率过低,降低画质
      this.lowerGraphicsQuality();
    } else if (currentFrameRate > targetFrameRate * 1.2) {
      // 帧率过高,提高画质
      this.increaseGraphicsQuality();
    }
  }
  
  // 对象池优化
  optimizeWithObjectPools(): void {
    // 预创建对象池
    ObstaclePool.preallocate(20);
    CollectiblePool.preallocate(30);
    ParticlePool.preallocate(100);
    
    // 定期清理未使用的对象
    setInterval(() => {
      this.cleanupUnusedObjects();
    }, 30000);
  }
  
  // 渲染优化
  applyRenderingOptimizations(): void {
    // 批量渲染
    RenderBatchManager.enable();
    
    // 纹理图集
    TextureAtlasManager.loadAtlases([
      'characters.atlas',
      'obstacles.atlas',
      'effects.atlas'
    ]);
    
    // 减少绘制调用
    this.minimizeDrawCalls();
  }
}

6.2 调试工具实现

// Debug/DebugOverlay.ets - 调试覆盖层
@Component
struct DebugOverlay {
  @State isVisible: boolean = false;
  @State debugInfo: DebugInfo = {};
  @State performanceStats: PerformanceStats = {};
  
  build() {
    if (this.isVisible) {
      Column({ space: 5 }) {
        // 性能统计
        DebugPanel({
          title: '性能统计',
          items: [
            { label: '帧率', value: `${this.performanceStats.fps} FPS` },
            { label: '内存', value: `${this.performanceStats.memory} MB` },
            { label: 'CPU', value: `${this.performanceStats.cpu}%` },
            { label: '绘制调用', value: this.performanceStats.drawCalls.toString() }
          ]
        })
        
        // 游戏状态
        DebugPanel({
          title: '游戏状态',
          items: [
            { label: '游戏状态', value: this.debugInfo.gameState },
            { label: '玩家位置', value: `(${this.debugInfo.playerX}, ${this.debugInfo.playerY})` },
            { label: '障碍物数量', value: this.debugInfo.obstacleCount.toString() },
            { label: '游戏速度', value: this.debugInfo.gameSpeed.toFixed(2) }
          ]
        })
        
        // 调试控制
        Row({ space: 10 }) {
          Button('慢动作', { type: ButtonType.Normal })
            .onClick(() => {
              GameEngine.getInstance().setTimeScale(0.5);
            })
          
          Button('无敌模式', { type: ButtonType.Normal })
            .onClick(() => {
              GameEngine.getInstance().toggleGodMode();
            })
          
          Button('跳过关卡', { type: ButtonType.Normal })
            .onClick(() => {
              GameEngine.getInstance().skipLevel();
            })
        }
      }
      .width(300)
      .padding(10)
      .backgroundColor('rgba(0,0,0,0.8)')
      .position({ x: 10, y: 10 })
      .borderRadius(5)
    }
  }
  
  // 显示/隐藏调试信息
  toggleVisibility(): void {
    this.isVisible = !this.isVisible;
    
    if (this.isVisible) {
      this.startDebugMonitoring();
    } else {
      this.stopDebugMonitoring();
    }
  }
}
