set; } = 2; + public string Name { get; set; } + public int Health { get; set; } + public int MaxHealth { get; set; } = 100; // V2 新增 + public List Skills { get; set; } = new(); // V2 新增 +} + +// 避免：没有版本控制 +[Serializable] +public class PlayerData +{ + public string Name { get; set; } + public int Health { get; set; } + // 未来新增字段会导致兼容性问题 +} +``` + +#### 2. 数据验证 + +```csharp +public class PlayerData +{ + private string _name; + + public string Name + { + get => _name; + set + { + if (string.IsNullOrWhiteSpace(value)) + throw new ArgumentException("Player name cannot be empty"); + _name = value; + } + } + + public int Health + { + get => _health; + set => _health = Math.Max(0, value); // 确保不为负数 + } + + public void Validate() + { + if (string.IsNullOrWhiteSpace(Name)) + throw new ValidationException("Player name is required"); + + if (Health < 0) + throw new ValidationException("Health cannot be negative"); + } +} +``` + +### 💾 存储策略 + +#### 1. 分层存储命名 + +```csharp +// 好的做法：有意义的分层结构 +var playerStorage = new ScopedStorage(rootStorage, "players"); +var saveStorage = new ScopedStorage(rootStorage, "saves"); +var settingsStorage = new ScopedStorage(rootStorage, "settings"); +var tempStorage = new ScopedStorage(rootStorage, "temp"); + +// 避免的混乱命名 +var storage1 = new ScopedStorage(rootStorage, "data1"); +var storage2 = new ScopedStorage(rootStorage, "data2"); +``` + +#### 2. 存储性能优化 + +```csharp +// 好的做法：批量操作和缓存 +public class OptimizedDataManager +{ + private readonly IStorage _storage; + private readonly Dictionary _writeBuffer = new(); + + public void QueueWrite(string key, T data) + { + _writeBuffer[key] = data; + } + + public async Task FlushWritesAsync() + { + var tasks = _writeBuffer.Select(kvp => _storage.WriteAsync(kvp.Key, kvp.Value)); + await Task.WhenAll(tasks); + _writeBuffer.Clear(); + } +} + +// 避免：频繁的小写入 +public class InefficientDataManager +{ + public void UpdatePlayerStat(string stat, int value) + { + _storage.Write($"player/stats/{stat}", value); // 每次都写入磁盘 + } +} +``` + +### 🔄 序列化优化 + +#### 1. 选择合适的序列化格式 + +```csharp +// 好的做法：根据需求选择格式 +public class GameSerializer +{ + // JSON：可读性好，调试方便 + public string SerializeForDebug(object data) => JsonConvert.SerializeObject(data, Formatting.Indented); + + // 二进制：体积小，性能好 + public byte[] SerializeForStorage(object data) => MessagePackSerializer.Serialize(data); + + // 压缩：减少存储空间 + public byte[] SerializeWithCompression(object data) + { + var json = JsonConvert.SerializeObject(data); + return Compress(Encoding.UTF8.GetBytes(json)); + } +} +``` + +#### 2. 自定义序列化逻辑 + +```csharp +public class PlayerInventory +{ + public Dictionary Items { get; set; } = new(); + + [JsonIgnore] // 排除不需要序列化的属性 + public int TotalWeight => Items.Sum(kvp => GetItemWeight(kvp.Key) * kvp.Value); + + [JsonProperty("total_items")] // 自定义序列化名称 + public int TotalItems => Items.Values.Sum(); + + public bool ShouldSerializeItems() // 条件序列化 + { + return Items.Count > 0; + } + + [OnDeserialized] // 反序列化后处理 + private void OnDeserialized(StreamingContext context) + { + // 初始化默认值或执行验证 + Items ??= new Dictionary(); + } +} +``` + +### 🏭 模块设计模式 + +#### 1. 单一职责模块 + +```csharp +// 好的做法：模块职责单一 +public class AudioModule : AbstractModule +{ + // 只负责音频相关功能 +} + +public class SaveModule : AbstractModule +{ + // 只负责存档相关功能 +} + +// 避免：功能过于庞大 +public class GameModule : AbstractModule +{ + // 音频、存档、UI、输入全部混在一起 +} +``` + +#### 2. 模块间通信 + +```csharp +public class SaveModule : AbstractModule +{ + public override void Install(IArchitecture architecture) + { + architecture.RegisterUtility(new SaveUtility()); + } +} + +public class PlayerModule : AbstractModule +{ + public override void Install(IArchitecture architecture) + { + architecture.RegisterSystem(new PlayerSystem()); + } + + public override void OnPhase(ArchitecturePhase phase, IArchitecture architecture) + { + if (phase == ArchitecturePhase.Ready) + { + // 通过事件进行模块间通信 + this.RegisterEvent(OnPlayerDeath); + } + } + + private void OnPlayerDeath(PlayerDeathEvent e) + { + // 触发保存模块的事件 + Context.SendEvent(new RequestAutoSaveEvent { Reason = "Player Death" }); + } +} +``` + +## 性能特性 + +### 📊 内存管理 + +- **缓存策略**：多层缓存减少磁盘 I/O +- **延迟加载**：按需加载资源，减少内存占用 +- **对象池化**：重用对象，减少 GC 压力 +- **内存映射**：大文件使用内存映射技术 + +### ⚡

扩展方法 + +GFramework.Godot 提供了 50+ 个 Node 扩展方法，大大简化了 Godot 开发中的常见操作。 + +### 🔍 节点查找与验证 + +```csharp +// 安全的节点获取 +var player = GetNodeX("Player"); // 自动 null 检查和类型转换 +var child = FindChildX("Player"); //

Context.SendEvent(new CharacterDeathEvent()); + } +} +``` + +## 最佳实践 + +### 🎯 属性使用策略 + +#### 1. 合理的属性组合 + +```csharp +// 好的做法：相关功能组合使用 +[Log] +[ContextAware] +public partial class BusinessLogicComponent : IComponent +{ + // 既有日志记录又有上下文访问 +} + +// 避免：不必要的属性 +[Log] // ❌ 静态工具类通常不需要日志 +public static class MathHelper +{ + public static int Add(int a, int b) => a + b; +} +``` + +#### 2. 命名约定 + +```csharp +// 好的做法：一致的命名 +[Log(fieldName = "Logger")] +public partial class PlayerController { } + +[Log(fieldName = "Logger")] +public partial class EnemyController { } + +// 避免：不一致的命名 +[Log(fieldName = "Logger")] +public partial class PlayerController { } + +[Log(fieldName = "CustomLogger")] +public partial class EnemyController { } +``` + +### 🏗️ 项目组织 + +#### 1. 分离生成器和业务逻辑 + +```csharp +// 好的做法：部分类分离 +// PlayerController.Logic.cs - 业务逻辑 +public partial class PlayerController : IController +{ + public void Move(Vector2 direction) + { + if (CanMove()) + { + UpdatePosition(direction); + Logger.Debug($"Player moved to {direction}"); + } + } +} + +// PlayerController.Generated.cs - 生成代码所在 +// 不需要手动维护，由生成器处理 +``` + +#### 2. 枚举设计 + +```csharp +// 好的做法：有意义的枚举设计 +[GenerateEnumExtensions] +public enum GameState +{ + MainMenu, // 主菜单 + Playing, // 游戏中 + Paused, // 暂停 + GameOver, // 游戏结束 + Victory // 胜利 +} + +// 避免：含义不明确的枚举值 +[GenerateEnumExtensions] +public enum State +{ + State1, + State2, + State3 +} +``` + +### 🔧 性能优化 + +#### 1. 避免过度日志 + +```csharp +// 好的做法：合理的日志级别 +[Log(minLevel = LogLevel.Information)] +public partial class PerformanceCriticalComponent +{ + public void Update() + { + // 只在必要时记录日志 + if (_performanceCounter % 1000 == 0) + { + Logger.Debug($"Performance: {_performanceCounter} ticks"); + } + } +} + +// 避免：过度日志记录 +[Log(minLevel = LogLevel.Debug)] +public partial class NoisyComponent +{ + public void Update() + { + Logger.Debug($"Frame: {Engine.GetProcessFrames()}"); // 太频繁 + } +} +``` + +#### 2. 延迟上下文初始化 + +```csharp +// 好的做法：延迟初始化 +[ContextAware(useLazy = true)] +public partial class LazyContextComponent : IComponent +{ + // 只有在第一次访问 Context 时才会初始化 + public void Initialize() + { + // 如果这里不需要 Context，就不会初始化 + SomeOtherInitialization(); + } +} +``` + +### 🛡️ 错误处理 + +#### 1. 上下文验证 + +```csharp +[ContextAware(validateContext = true)] +public partial class SafeContextComponent : IComponent +{ + public void ProcessData() + { + if (Context.IsInvalid) + { + Logger.Error("Context is invalid, cannot process data"); + return; + } + + // 安全地使用 Context + var model = Context.GetModel(); + // ... + } +} +``` + +#### 2. 异常处理配合 + +```csharp +[Log] +[ContextAware] +public partial class RobustComponent : IComponent +{ + public void RiskyOperation() + { + try + { + var model = Context.GetModel(); + model.PerformRiskyOperation(); + Logger.Info("Operation completed successfully"); + } + catch (Exception ex) + { + Logger.Error($"Operation failed: {ex.Message}"); + Context.SendEvent(new OperationFailedEvent { Error = ex.Message }); + } + } +} +``` + +## 常见问题 + +### Q: 为什么需要标记类为 `partial`？ + +**A**: 源代码生成器需要向现有类添加代码，`partial` 关键字允许一个类的定义分散在多个文件中。生成器会在编译时创建另一个部分类文件，包含生成的代码。 + +```csharp +[Log] +public partial class MyClass { } // ✅ 需要 partial + +[Log] +public class MyClass { } // ❌ 编译错误，无法添加生成代码 +``` + +### Q: 生成的代码在哪里？ + +**A**: 生成的代码在编译过程中创建，默认位置在 `obj/Debug/net6.0/generated/` 目录下。可以在项目文件中配置输出位置： + +```xml + + Generated + +``` + +### Q: 如何调试生成器问题？ + +**A**: 生成器提供了详细的诊断信息： + +1. **查看错误列表**：编译错误会显示在 IDE 中 +2. **查看生成文件**：检查生成的代码文件 +3. **启用详细日志**：在项目文件中添加： + +```xml + + true + +``` + +### Q: 可以自定义生成器吗？ + +**A**: 当前版本的生成器支持有限的配置。如需完全自定义，可以创建自己的源代码生成器项目。 + +### Q: 性能影响如何？ + +**A**: 源代码生成器对运行时性能的影响几乎为零： + +- **编译时**：可能会增加编译时间（通常几秒） +- **运行时**：与手写代码性能相同 +- **内存使用**：与手写代码内存使用相同 + +### Q: 与依赖注入框架兼容吗？ + +**A**: 完全兼容。生成器创建的是标准代码，可以与任何依赖注入框架配合使用： + +```csharp +[Log] +[ContextAware] +public partial class ServiceComponent : IService +{ + // 可以通过构造函数注入依赖 + private readonly IDependency _dependency; + + public ServiceComponent(IDependency dependency) + { + _dependency = dependency; + Logger.Info("Service
