# 事件系统
|
|||
|
|
|
|||
|
|
## 分类
|
|||
|
|
|
|||
|
|
- 核心框架
|
|||
|
|
|
|||
|
|
## 目的
|
|||
|
|
|
|||
|
|
提供客户端内部事件（CTC）和服务器消息事件（STC）的统一派发、监听和释放机制。
|
|||
|

|

|
|
|
|||
|
|
## 核心路径
|
|||
|
|
|
|||
|
|
- 框架层：`Assets/Game/GameHFScripte/CopyToHF/Event/`
|
|||
|
|
- 功能层：`Assets/Game/GameHFScripte/GameFunction/Event/`
|
|||
|
|
- STC 事件参数：`Assets/Game/GameHFScripte/GameFunction/Event/STCEventArg/`
|
|||
|
|

|
|
## 核心类
|
|||
|
|
|
|||
|
|
| 类 | 职责 |
|
|||
|
|
|---|---|
|
|||
|
|
| `HFEventManager` | 事件管理器单例，继承 `AbsHFSingleRunTime<HFEventManager>` |
|
|||
|
|
| `TCEvent` | CTC 事件句柄 |
|
|||
|
|
| `STCEvent` | STC 事件句柄 |
|
|||
|
|
| `CTCHandle` | CTC 事件处理器定义位置 |
|
|||
|
|
| `AbsHFEventArg<K,T>` | 事件参数基类 |
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
## 事件派发链路
|
|||
|
|
|
|||
|
|
### CTC 事件
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
AbsHFEventArg<enHFCTCEvent>.Dispatch()
|
|||
|
|
-> HFEventManager.Instance.TCEvent.Dispatch(arg)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
CTC 事件来源：
|
|||
|
|
|
|||
|
|
- 功能代码手动创建事件参数对象。
|
|||
|
|
- 设置字段后调用 `.Dispatch()`。
|
|||
|
|
- 示例：业务管理器派发初始化事件、背包更新事件。
|
|||
|
|
|
|||
|
|
### STC 事件
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
AbsHFEventArg<enHFSTCEvent>.Dispatch()
|
|||
|
|
-> HFEventManager.Instance.STCEvent.Dispatch(arg)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
STC 事件来源：
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
WSSession 收到 protobuf S2C
|
|||
|
|
-> 反射创建 HFEvent_STC_{MessageTypeName}
|
|||
|
|
-> 写入 Request / ErrorCode
|
|||
|
|
-> Dispatch 到 STCEvent
|
|||
|
|
```
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
## 监听与派发机制
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
AddListener<TEventArg>(eventId, callback)
|
|||
|
|
-> 按 eventId 分组
|
|||
|
|
-> 按事件参数类型 hash 分组
|
|||
|
|
|
|||
|
|
Dispatch(arg)
|
|||
|
|
-> 根据 arg.eventId 找事件组
|
|||
|
|
-> 根据 arg.GetType() 找具体类型监听
|
|||
|
|
-> Invoke callbacks
|
|||
|
|
-> arg.Recycle()
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 使用规则
|
|||
|
|
|
|||
|
|
- UI 窗口在 `OnOpen` 中注册的事件，必须在 `OnClose` 中移除。
|
|||
|
|
- 管理器监听 STC 事件通常在初始化时添加，在 `Recycle` 或销毁时移除。
|
|||
|
|
- 不要直接监听与当前模块无关的事件。
|
|||
|
|
- 事件参数对象由框架自动回收，业务代码不要重复释放。
|
|||
|

## 错误响应
|
|||
|
|
|
|||
|
|
当服务器返回错误响应时：
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
messagePage.IsError = true
|
|||
|
|
-> 解析 ErrorResponse
|
|||
|
|
-> 派发 HFEvent_ErrorCode
|
|||
|
|
-> 同时仍创建对应 HFEvent_STC_* 并写入 ErrorCode
|
|||
|
|
```

|||
