C语言实战：超级玛丽游戏

web 2025/7/19 18:18:34

以下是一个简化版的超级玛丽游戏实现，使用C语言和SDL库。这个版本包含了基本的游戏元素：角色移动、跳跃、平台和简单的碰撞检测。

}

如何运行这个游戏

你需要安装SDL2库：
- 在Linux上：sudo apt-get install libsdl2-dev
- 在Mac上：brew install sdl2
- 在Windows上：下载SDL2开发库并配置你的编译器
编译命令：
```
gcc super_mario.c -o super_mario -lSDL2
```
运行游戏：
```
./super_mario
```
