// 子系统接口或类定义
public interface ISubSystemA
{void Initialize();
}public class SubSystemA : ISubSystemA
{public void Initialize(){Debug.Log(Subsystem A initialized.);}
}public interface ISubSystemB
{void Initialize();
}public class SubSystemB : ISubSystemB
{public void Initialize(){Debug.Log(Subsystem B initialized.);}
}// 外观Facade类
public class GameInitializerFacade
{private ISubSystemA _subSystemA;private ISubSystemB _subSystemB;public GameInitializerFacade(ISubSystemA subSystemA, ISubSystemB subSystemB){_subSystemA subSystemA;_subSystemB subSystemB;}public void InitializeGame(){_subSystemA.Initialize();_subSystemB.Initialize();Debug.Log(All subsystems initialized through Facade.);}
}// 使用外观模式初始化游戏
public class GameManager : MonoBehaviour
{void Start(){var initializer new GameInitializerFacade(new SubSystemA(), new SubSystemB());initializer.InitializeGame();}
}
示例2管理音频播放
public interface IAudioPlayer
{void PlayMusic(string track);void PlaySoundEffect(string effect);
}public class AudioPlayer : IAudioPlayer
{// 实现音频播放逻辑...
}public class AudioManagerFacade
{private IAudioPlayer _audioPlayer;public AudioManagerFacade(IAudioPlayer audioPlayer){_audioPlayer audioPlayer;}public void PlayMainMenuMusic(){_audioPlayer.PlayMusic(MainTheme);}public void PlayJumpSound(){_audioPlayer.PlaySoundEffect(Jump);}
}// 在游戏中通过外观来控制音频
public class SceneController : MonoBehaviour
{private AudioManagerFacade _audioManager;void Start(){_audioManager new AudioManagerFacade(new AudioPlayer());_audioManager.PlayMainMenuMusic();}void OnJump(){_audioManager.PlayJumpSound();}
}示例3场景加载流程
public interface ISceneLoader
{void Load(SceneName scene);void Unload(SceneName scene);
}public class SceneManager : ISceneLoader
{// 实现场景加载卸载功能...
}public class SceneLoadingFacade
{private ISceneLoader _sceneLoader;public SceneLoadingFacade(ISceneLoader loader){_sceneLoader loader;}public void LoadMainMenu(){_sceneLoader.Load(SceneName.MainMenu);}public void LoadGameplay(){_sceneLoader.Unload(SceneName.MainMenu);_sceneLoader.Load(SceneName.Gameplay);}
}// 游戏流程控制
public class TransitionController : MonoBehaviour
{private SceneLoadingFacade _loadingFacade;void Start(){_loadingFacade new SceneLoadingFacade(new SceneManager());_loadingFacade.LoadMainMenu();}public void OnPlayButtonClicked(){_loadingFacade.LoadGameplay();}
}示例4UI管理器
public interface IUIManager
{void ShowMenu(MenuType menu);void HideMenu(MenuType menu);
}public class UIManager : IUIManager
{// 实现菜单显示隐藏逻辑...
}public class UIFacade
{private IUIManager _uiManager;public UIFacade(IUIManager manager){_uiManager manager;}public void OpenSettings(){_uiManager.ShowMenu(MenuType.Settings);}public void CloseAllMenus(){_uiManager.HideMenu(MenuType.All);}
}// 游戏中UI控制
public class MenuInteraction : MonoBehaviour
{private UIFacade _uiFacade;void Start(){_uiFacade new UIFacade(new UIManager());}void OnSettingsButtonClick(){_uiFacade.OpenSettings();}void OnBackPressed(){_uiFacade.CloseAllMenus();}
}示例5网络服务通信
public interface INetworkService
{void Connect(string address);void SendData(byte[] data);void Disconnect();
}public class NetworkServiceImpl : INetworkService
{// 实现网络连接和数据发送逻辑...
}public class NetworkServiceFacade
{private INetworkService _networkService;public NetworkServiceFacade(INetworkService service){_networkService service;}public void ConnectToServer(string ip, int port){string address ${ip}:{port};_networkService.Connect(address);}public void SendGameData(GameData data){byte[] serializedData SerializeGameData(data);_networkService.SendData(serializedData);}public void DisconnectFromServer(){_networkService.Disconnect();}
}// 游戏中网络模块调用
public class NetworkController : MonoBehaviour
{private NetworkServiceFacade _networkFacade;void Start(){_networkFacade new NetworkServiceFacade(new NetworkServiceImpl());}void OnConnectButtonClicked(){_networkFacade.ConnectToServer(192.168.0.1, 12345);}void OnSendGameData(){GameData gameData GetGameData();_networkFacade.SendGameData(gameData);}void OnDisconnectButtonClicked(){_networkFacade.DisconnectFromServer();}
}以上每个例子都展示了如何通过外观模式将复杂的子系统操作封装成简单易用的方法在Unity项目中提供了更高层次的抽象和控制。
