## 核心组件
### AbstractGodotModule - Godot模块基类
AbstractGodotModule是Godot模块系统的核心抽象基类,定义了模块与Godot节点的集成接口:
```mermaid
classDiagram
class AbstractGodotModule {
<>
+Node Node
+OnPhase(phase, architecture) void
+OnArchitecturePhase(phase) void
+Install(architecture) void
+OnDetach() void
+OnAttach(architecture) void
}
class IGodotModule {
<>
+Node Node
+OnAttach(architecture) void
+OnDetach() void
}
class AbstractArchitecture {
<>
-IGodotModule[] _extensions
-ArchitectureAnchor _anchor
+InstallGodotModule~TModule~(module) Task
+Destroy() void
}
AbstractGodotModule ..|> IGodotModule
AbstractArchitecture --> AbstractGodotModule : "管理模块"
```

### AbstractArchitecture - 架构生命周期管理
AbstractArchitecture负责将GFramework架构与Godot生命周期无缝集成:
```mermaid
sequenceDiagram
participant Scene as "Godot场景"
participant Arch as "AbstractArchitecture"
participant Anchor as "ArchitectureAnchor"
participant Module as "IGodotModule"
Scene->>Arch : Initialize()
Arch->>Arch : Init()
Arch->>Arch : AttachToGodotLifecycle()
Arch->>Anchor : 创建锚点节点
Anchor->>Scene : 添加到场景树
Arch->>Arch : InstallModules()
Arch->>Module : Install(this)
Arch->>Arch : WaitUntilReady()
Arch->>Anchor : AddChild(Module.Node)
Module->>Module : OnAttach(this)
Note over Scene,Module : 场景销毁时自动清理
Scene->>Anchor : _ExitTree()
Anchor->>Arch : Destroy()
Arch->>Module : OnDetach() 循环调用
```

[*] --> 创建实例
创建实例 --> 预加载缓存 : Preload()
创建实例 --> 直接使用 : AlwaysCreate
创建实例 --> 复用缓存 : Reuse
预加载缓存 --> 等待使用
复用缓存 --> 等待使用
直接使用 --> 使用中
等待使用 --> 使用中 : GetOrCreate()
使用中 --> 回收到缓存 : Recycle()
使用中 --> 销毁实例 : ClearCache()
回收到缓存 --> 等待使用
销毁实例 --> [*]
```

## 性能考虑
### 节点池化策略
推荐使用AbstractNodePoolSystem管理高频创建的对象:
1. **预加载场景**:在初始化时预加载所有需要的场景
2. **批量创建**:使用Preload方法批量创建实例
3. **智能回收**:实现CanDespawn方法确保只有空闲实例被回收
4. **缓存配置**:根据UI类型设置合适的缓存大小和淘汰策略
### 资源管理优化
- 使用Godot的异步加载机制避免主线程阻塞
- 实现资源优先级队列,确保关键资源优先加载
- 定期清理未使用的资源,避免内存泄漏
## 故障排除指南
### 常见问题及解决方案
#### 模块未正确初始化
**问题**:模块的OnAttach方法没有被调用
**解决方案**:
1. 确保InstallGodotModule方法在InstallModules中正确调用
2. 检查模块的Node属性返回有效的Godot节点
3. 验证架构锚点已正确创建和添加到场景树
#### 信号连接泄漏
**问题**:节点销毁后信号处理器仍在执行
**解决方案**:
1. 使用UnRegisterWhenNodeExitTree方法自动清理
2. 避免使用传统的+=事件订阅方式
3. 确保所有信号连接都在节点生命周期内管理
#### 协程取消问题
**问题**:协程在节点销毁后仍在运行
**解决方案**:
1. 使用CancelWith扩展方法绑定节点生命周期
2. 在协程中定期检查节点存活状态
3. 实现适当的异常处理机制

### 快速开始模板
```csharp
// 架构定义
public class MyGameArchitecture : AbstractArchitecture
{
protected override void InstallModules()
{
InstallGodotModule(new InputModule());
InstallGodotModule(new AudioManager());

}
// 模块实现
public partial class InputModule : AbstractGodotModule
{
public override Node Node => this;
public override void Install(IArchitecture architecture)
{
architecture.RegisterSystem(new InputSystem());

}
```
### 最佳实践清单
1. **模块化设计**:每个模块专注于单一功能领域
2. **生命周期管理**:始终使用自动清理机制
