# OnlineRpg - C++ 在线回合制对战游戏
## 项目简介
本项目是一个基于 C/S 架构的在线回合制对战游戏，使用纯 C++ 开发，控制台界面。
## 🚀 快速开始
### 1. 启动服务器
```bash
cd /mnt/e/50425/Documents/Github/OnlineRpg
./build/bin/server
```
### 2. 启动客户端（新开终端）
```bash
cd /mnt/e/50425/Documents/Github/OnlineRpg
./build/bin/client
```
### 3. 开始游戏
1. 注册账号 → 2. 登录 → 3. 创建角色 → 4. 进入大厅 → 5. 战斗！
📖 **详细游戏指南**: 查看 [`如何运行和游戏.md`](如何运行和游戏.md)
## 核心技术
- **多态**: ICharacter 和 ISkill 抽象基类
- **模板 + 链表**: 手写 HistoryLog<T> 泛型链表
- **STL**: std::map, std::vector, std::thread, std::mutex
- **网络编程**: 原生 Socket API (Winsock/POSIX)
- **数据库**: SQLite3
## 系统要求
- C++17 或更高版本
- CMake 3.15+
- SQLite3 (可选，项目包含 amalgamation 版本)
### Windows
- Visual Studio 2019+ 或 MinGW
- Windows 7+
### Linux
- GCC 7+ 或 Clang 5+
- POSIX Sockets
## 项目结构

```
## 构建步骤
### Windows (Visual Studio)
```powershell
# 创建构建目录
mkdir build
cd build
# 生成 Visual Studio 项目
cmake ..
# 构建
cmake --build . --config Release
# 运行
.\bin\Release\server.exe
.\bin\Release\client.exe
```
### Windows (MinGW)
```powershell
mkdir build
cd build
cmake -G "MinGW Makefiles" ..
cmake --build .
.\bin\server.exe
.\bin\client.exe
```
### Linux
```bash
mkdir build
cd build
cmake ..
make -j$(nproc)
./bin/server
./bin/client
```
## 使用说明
### 启动服务器
```bash
./bin/server [port]
# 默认端口: 8888
```
### 启动客户端
```bash
./bin/client [server_ip] [port]
# 默认: localhost:8888
```
### 游戏操作
1. **注册/登录**: 启动客户端后选择注册或登录
2. **大厅聊天**: 直接输入消息发送
3. **查看玩家**: 输入 `/list` 查看在线玩家
4. **发起对战**: 输入 `/invite <玩家名>` 邀请对战
5. **战斗**: 轮到自己时输入技能编号进行攻击
## 功能特性
- ✅ 用户注册/登录 (数据库持久化)
- ✅ 游戏大厅 (公共聊天)
- ✅ 在线玩家列表
- ✅ 1v1 对战邀请
- ✅ 回合制战斗系统
- ✅ 多职业系统 (战士、法师)
- ✅ 技能系统
- ✅ 战斗回放

### 游戏大厅（中文）
```
游戏大厅
====================
1. 聊天
2. 查看在线玩家
3. 邀请战斗

### 战斗系统（中文）
```
*** 战斗开始！***
对手：player2

```
## 技术说明
- 所有中文字符串使用 UTF-8 编码
- C++17 标准原生支持 UTF-8 字符串字面量
- 无需额外的字符编码转换库
- 终端需要支持 UTF-8 显示（现代终端默认支持）
## 未来改进建议
1. 考虑将技能名称本地化（当前为英文：NormalAttack、HeavyStrike、Fireball 等）
2. 职业名称本地化（Warrior → 战士、Mage → 法师）
3. 创建双语配置文件，支持语言切换
4. 添加更多中文友好的提示信息
## 测试建议
1. 注册新账户测试中文提示
2. 登录并浏览大厅菜单
3. 测试聊天功能的中文显示
4. 进行战斗测试，观察战斗日志中文化
5. 测试错误消息的中文显示（如用户名重复、密码错误等）

```
### 7. 战斗策略建议
#### 战士策略：
1. **开局**: 使用防御姿态提升防御
2. **中期**: 积累能量后使用强力打击
3. **残血**: 优先普通攻击保持输出
4. **对法师**: 利用高防御抗魔法，近身输出
#### 法师策略：
1. **开局**: 火球术快速压血
2. **中期**: 使用奥术护盾减伤
3. **残血**: 治疗术回血，拉扯战线
4. **对战士**: 保持距离，魔法风筝
### 8. 高级功能
#### 8.1 查看战斗历史
战斗房间使用 `HistoryLog<string>` 记录所有战斗日志：
- 每回合的行动
- 伤害计算
- 状态变化
- 胜负结果
#### 8.2 多人同时在线
- 服务器支持多客户端连接
- 每个客户端独立线程处理
- 使用 `std::map` 管理所有连接
- `std::mutex` 保证线程安全
#### 8.3 数据持久化
- 用户账号保存在 `data/game.db`
- 角色数据自动保存
- 重新登录后保留等级和属性
## 多人游戏示例
### 场景：三人同时在线
**终端1 - 服务器**
```bash
./build/bin/server
# 保持运行
```
**终端2 - 玩家A (xiaoming)**
```bash
./build/bin/client
# 登录 -> 创建战士 -> 进入大厅
Select: 1
Enter message: 有人组队吗？
```
**终端3 - 玩家B (xiaohua)**
```bash
./build/bin/client
# 登录 -> 创建法师 -> 进入大厅
# 看到 xiaoming 的聊天
Select: 3
Enter target: xiaoming
# 邀请战斗
```
**终端4 - 玩家C (xiaogang)**
```bash
./build/bin/client
# 旁观，或者等战斗结束后挑战胜者
```
## 常见问题
### Q1: 连接失败怎么办？
**检查服务器是否启动：**
```bash
ps aux | grep server
```
**检查端口是否被占用：**
```bash
netstat -an | grep 8888
```
**重启服务器：**
```bash
killall server # 如果有旧进程
./build/bin/server
```
### Q2: 数据库错误？
**删除并重新创建：**
```bash
rm -f data/game.db
./build/bin/server # 自动重建表结构
```
### Q3: 客户端卡住了？
**重新连接：**
- 按 `Ctrl+C` 退出客户端
- 重新运行 `./build/bin/client`
- 重新登录
### Q4: 忘记密码了？
**直接修改数据库（开发测试用）：**
```bash
sqlite3 data/game.db
```
```sql
-- 查看所有用户
SELECT * FROM Users;
-- 重置密码 (hash值需要计算)
UPDATE Users SET PasswordHash = '新密码hash' WHERE Username = 'xiaoming';
```
**或者注册新账号。**
### Q5: 如何在 Windows 上运行？
项目代码支持跨平台，在 Windows 上：
1. **使用 Visual Studio:**
- 打开 CMake 项目
- 选择 x64-Release 配置
- 生成解决方案
- 运行 server.exe 和 client.exe
2. **使用 MinGW:**
```cmd
cmake -B build -G "MinGW Makefiles"
cmake --build build
build\bin\server.exe
```
## 技术特性展示
### 1. 多态 (Polymorphism)
```cpp
// 战斗中，不同职业使用各自的技能
ICharacter* player = new Warrior();
ISkill* skill = new PowerStrike();
skill->execute(*player, *enemy); // 多态调用
```
### 2. 模板与链表 (Templates & Linked List)
```cpp
// 战斗历史记录
HistoryLog<string> battleLog;
battleLog.append("Round 1: Player attacks!");
battleLog.append("Enemy takes 30 damage");
// 使用手写的 Node<T> 链表存储
```
### 3. STL 容器
```cpp
// 客户端管理
std::map<int, shared_ptr<ClientHandler>> clients;
// 战斗房间管理
std::map<int, shared_ptr<BattleRoom>> rooms;
// 多线程
std::thread clientThread(&ClientHandler::run, handler);
```
### 4. 网络编程
```cpp
// 跨平台 Socket 封装
SocketWrapper socket;
socket.connect("127.0.0.1", 8888);
socket.sendLine("LOGIN|xiaoming|123456");
string response = socket.recvLine();
```
### 5. 数据库
```cpp
// SQLite3 操作
Database db("data/game.db");
db.registerUser("xiaoming", "123456");
db.createCharacter(userId, "Warrior");
```
### 6. 线程安全
```cpp
// 多线程保护
std::mutex m_clientsMutex;
{
std::lock_guard<std::mutex> lock(m_clientsMutex);
m_clients[clientId] = handler;
}
```

# 战斗系统输入处理修复
## 🐛 问题描述
### 症状1：战斗中输入被错误处理
```
>>> 你的回合 <<<
【战斗】> attack
无效选项。请输入1-5。 ❌ 错误：被大厅菜单处理器处理
```
### 症状2：不断显示战斗菜单
```
【战斗】> 1
================================
战斗中
================================
等待你的回合...
================================
【战斗】> 2
================================
战斗中
================================
等待你的回合...
```
### 症状3：连接崩溃
```
terminate called without an active exception
Aborted
```
## 🔍 根本原因
### 主循环逻辑问题
**修复前的代码**：
```cpp
while (m_isRunning && m_isConnected) {
if (!m_isAuthenticated) {
showMainMenu();
} else if (m_inBattle) {
showBattleMenu(); // ❌ 不管是否轮到玩家都调用
} else {
showLobbyMenu();
}
std::this_thread::sleep_for(std::chrono::milliseconds(100));
}
```
**问题分析**：
1. 当 `m_inBattle = true` 但 `m_waitingForTurn = false` 时
2. `showBattleMenu()` 被调用 → 等待输入
3. 用户输入后，`handleBattleInput()` 检查 `!m_waitingForTurn` 直接返回
4. 循环继续，100ms 后再次调用 `showBattleMenu()`
5. **无限显示菜单**
### 状态机混乱
战斗有三个状态：
- 未认证 → 显示主菜单
- 在大厅 → 显示大厅菜单
- 在战斗中
- **轮到玩家** → 显示战斗菜单，接受输入
- **不是玩家回合** → 静默等待，不显示菜单
原来的代码只区分了前两个状态，导致第三个状态处理错误。
## ✅ 修复方案
### 1. 改进主循环逻辑
```cpp
void GameClient::run() {
if (!connect()) {
return;
}
while (m_isRunning && m_isConnected) {
if (!m_isAuthenticated) {
showMainMenu();
} else if (m_inBattle && m_waitingForTurn) {
// ✓ 只在战斗中且轮到玩家时才显示战斗菜单
showBattleMenu();
} else if (!m_inBattle) {
// ✓ 不在战斗中，显示大厅菜单
showLobbyMenu();
} else {
// ✓ 在战斗中但不是玩家回合，静默等待
std::this_thread::sleep_for(std::chrono::milliseconds(100));
}
}
}
```
**关键改进**：
- 添加 `m_waitingForTurn` 检查
- 只在 `m_inBattle && m_waitingForTurn` 时显示战斗菜单
- 不是玩家回合时进入等待状态，不显示任何菜单
### 2. 简化战斗菜单
```cpp
void GameClient::showBattleMenu() {
printTitle("战斗中");
std::cout << "输入 'attack' 或 '攻击' 使用普通攻击" << std::endl;
printSeparator();
std::string input;
showPrompt();
std::getline(std::cin, input);
handleBattleInput(input);
}
```
**移除了不必要的检查**，因为主循环已经保证只在正确时机调用。
### 3. 改进输入处理
```cpp
void GameClient::handleBattleInput(const std::string& input) {
if (input.empty()) {
return;
}
if (input == "attack" || input == "攻击") {
std::string msg = Protocol::buildMessage(Protocol::C2S_BATTLE_ACTION, {"0", "opponent"});
sendMessage(msg);
m_waitingForTurn = false; // 行动后设置为 false
} else {
std::cout << "无效命令。请输入 'attack' 或 '攻击'" << std::endl;
}
}
```
**关键点**：
- 执行攻击后设置 `m_waitingForTurn = false`
- 添加友好的错误提示
## 📊 状态转换流程
### 正确的战斗流程
```
1. 玩家A邀请玩家B
↓
2. 玩家B接受邀请
↓
3. 服务器发送 S2C_BATTLE_START
→ m_inBattle = true
↓
4. 服务器发送 S2C_BATTLE_TURN (YOUR_TURN)
→ m_waitingForTurn = true
↓
5. 主循环检测到 (m_inBattle && m_waitingForTurn)
→ 调用 showBattleMenu()
↓
6. 玩家输入 "attack"
→ handleBattleInput() 处理
→ 发送 C2S_BATTLE_ACTION
→ m_waitingForTurn = false
↓
7. 主循环检测到 (m_inBattle && !m_waitingForTurn)
→ 进入等待状态（不显示菜单）
↓
8. 服务器处理回合，发送战斗日志
→ 显示战斗结果
↓
9. 服务器发送 S2C_BATTLE_TURN (OPP_TURN)
→ 保持 m_waitingForTurn = false
→ 继续等待
↓
10. 对手行动完毕，服务器发送 S2C_BATTLE_TURN (YOUR_TURN)
→ m_waitingForTurn = true
→ 回到步骤 5
```
## 🧪 测试步骤
### 步骤1：重启客户端
```bash
cd /mnt/e/50425/Documents/Github/OnlineRpg
./build/bin/client
```
### 步骤2：登录两个玩家
- 终端1：玩家A登录
- 终端2：玩家B登录
### 步骤3：发起战斗邀请
**玩家A**：
```
【玩家A】> 3
目标玩家用户名：玩家B用户名
```
**玩家B**：
```
*** 玩家A 邀请你战斗！***
输入 'accept 玩家A' 接受，或 'reject 玩家A' 拒绝
【玩家B】> accept 玩家A
```
### 步骤4：战斗测试
**预期行为**：
```
*** 战斗开始！***
对手：玩家B（Mage）
====================
>>> 你的回合 <<<
输入 'attack' 使用普通攻击
================================
战斗中
================================
输入 'attack' 或 '攻击' 使用普通攻击
================================
【战斗】> attack ← 输入攻击命令
【战斗】玩家A HP:150 ← 显示战斗日志
【战斗】玩家A 使用 NormalAttack 攻击 玩家B，造成 15 点伤害！
← 自动进入等待状态，不显示菜单
>>> 对手的回合...
【战斗】玩家B HP:85
【战斗】玩家B 使用 Fireball 攻击 玩家A，造成 28 点伤害！
>>> 你的回合 <<< ← 再次轮到玩家
================================
战斗中
================================
输入 'attack' 或 '攻击' 使用普通攻击
================================
【战斗】> attack
```
**成功标志**：
- ✅ 输入 `attack` 后正确执行攻击
- ✅ 不是自己回合时不显示菜单
- ✅ 没有"无效选项。请输入1-5。"错误
- ✅ 战斗日志正常显示
- ✅ 连接保持稳定，不崩溃
## 🔧 相关文件
- `src/client/GameClient.cpp` - 主要修复文件
- `src/client/GameClient.h` - 状态变量定义
- `include/common/Protocol.h` - 协议定义
## 📈 后续优化建议
1. **添加更多技能选择**
```
【战斗】> skill
可用技能：
0. 普通攻击
1. 强力打击 (消耗10MP)
2. 防御姿态 (消耗5MP)
选择技能编号：
```
2. **显示双方状态**
```
你：玩家A (Warrior) HP:122/150 MP:15/20
对手：玩家B (Mage) HP:85/100 MP:10/50
```
3. **战斗历史查看**
```
【战斗】> history
第1回合：玩家A 使用 普通攻击 造成 15 伤害
第2回合：玩家B 使用 火球术 造成 28 伤害
第3回合：玩家A 使用 强力打击 造成 30 伤害
```
4. **逃跑选项**
```
【战斗】> flee
你逃离了战斗！
```
## ✨ 总结
修复了战斗系统的输入处理逻辑，通过改进主循环状态判断，确保：
- 战斗菜单只在正确时机显示
- 输入被正确的处理器处理
- 不是玩家回合时静默等待
- 避免了菜单无限显示和连接崩溃问题
现在战斗系统应该能够正常工作了！

# 战斗邀请响应功能修复
## 问题描述
当玩家在游戏大厅收到战斗邀请时，输入 `accept 20241111` 或 `reject 20241111` 会被识别为"无效选项"，无法正确处理邀请响应。
### 错误场景
```
【20245738】>
*** 20241111 邀请你战斗！***
输入 'accept 20241111' 接受，或 'reject 20241111' 拒绝
【20245738】> accept 20241111
无效选项。请输入1-5。 ❌ 错误提示
```
## 原因分析
在 `GameClient::handleLobbyInput()` 函数中，代码只处理数字选项 1-5，没有处理 `accept` 和 `reject` 命令。
### 修复前的代码
```cpp
void GameClient::handleLobbyInput(const std::string& input) {
if (input.empty()) {
return;
}
if (input == "1") {
// Chat
...
} else if (input == "2") {
// List players
...
}
// ... 其他选项
else {
std::cout << "无效选项。请输入1-5。" << std::endl; // ❌ 所有非1-5的输入都报错
}
}
```
## 解决方案
在 `handleLobbyInput()` 函数开头添加邀请响应命令的处理逻辑：
### 修复后的代码
```cpp
void GameClient::handleLobbyInput(const std::string& input) {
if (input.empty()) {
return;
}
// ✅ 新增：检查是否是邀请响应命令
if (input.find("accept ") == 0 || input.find("reject ") == 0) {
size_t spacePos = input.find(' ');
if (spacePos != std::string::npos) {
std::string response = input.substr(0, spacePos); // "accept" 或 "reject"
std::string inviter = input.substr(spacePos + 1); // 邀请者用户名
bool accept = (response == "accept");
std::string msg = Protocol::buildMessage(Protocol::C2S_INVITE_RSP,
{inviter, accept ? "yes" : "no"});
sendMessage(msg);
}
return; // 处理完毕，直接返回
}
// 原有的菜单选项处理
if (input == "1") {
...
}
...
}
```
## 功能说明
### 1. 命令格式解析
- 检测以 `accept ` 或 `reject ` 开头的输入
- 提取命令类型（accept/reject）
- 提取邀请者用户名
### 2. 协议构建
- `accept username` → 发送 `INVITE_RSP|username|yes`
- `reject username` → 发送 `INVITE_RSP|username|no`
### 3. 服务器处理
服务器收到邀请响应后，会通过 `ClientHandler::handleInviteResponse()` 处理：
- 验证邀请是否有效
- 接受：创建战斗房间，双方进入战斗
- 拒绝：通知邀请者被拒绝
## 正确使用流程
### 玩家A（邀请方）
```
【20241111】> 3
目标玩家用户名：20245738
【服务器】邀请已发送（等待服务器实现此消息）
```
### 玩家B（被邀请方）
```
【20245738】>
*** 20241111 邀请你战斗！***
输入 'accept 20241111' 接受，或 'reject 20241111' 拒绝
【20245738】> accept 20241111
```
### 接受邀请后
```
*** 战斗开始！***
对手：20241111
...
>>> 你的回合 <<<
【战斗】>
```
### 拒绝邀请
```
【20245738】> reject 20241111
【服务器】已拒绝邀请
```

UserID INTEGER NOT NULL,
CharacterClass TEXT NOT NULL,
CharacterName TEXT NOT NULL,

```
## 编译问题解决
### SQLite3 链接错误
**问题**: undefined reference to sqlite3_* functions
**解决方案**:
1. 在 CMakeLists.txt 中启用 C 语言支持:
```cmake
project(OnlineRpg VERSION 1.0.0 LANGUAGES C CXX)
```
2. 确保 SQLite amalgamation 文件被包含:
```cmake
set(COMMON_SOURCES
src/common/SocketWrapper.cpp
src/common/Protocol.cpp
src/common/Database.cpp
${SQLITE_SRC} # 包含 lib/sqlite3.c
)
```
3. 链接服务器时包含 SQLite:
```cmake
target_link_libraries(server core common ${SQLITE_LIBS} ${PLATFORM_LIBS})
```
### 前向声明错误
**问题**: invalid use of incomplete type 'class BattleRoomManager'
**解决方案**: 在 .cpp 文件中包含完整的头文件:
```cpp
#include "server/BattleRoomManager.h" // 而不是前向声明
```
