这个项目是对于有道词典笔二代适配的 DOOM 引擎移植版本，基于PureDOOM单头文件开发，对于320x170屏幕上下两边稍微有裁剪。
本项目使用OTG键盘操作，↑↓←→控制方向，数字切枪，Ctrl开枪,左Shift奔跑，Esc菜单/暂停,空格开门等。
确保你在开发机环境（如 Debian/Ubuntu）中已安装 aarch64-linux-gnu-gcc 交叉编译工具链。
在包含 PenDOOM.c 和 PureDOOM.h 的目录下执行：
aarch64-linux-gnu-gcc -static -O2 -s -o PenDOOM PenDOOM.c -lm将编译生成的PenDOOM与游戏文件（.wad）放于一个目录下赋予权限并运行
chmod +x PenDOOM
./PenDOOM -iwad 游戏文件.wad📄 协议与致谢
本项目基于 PureDOOM 单头文件库构建。该项目遵循 id Software 的原始 DOOM 源码协议，仅供个人学习和研究使用，严禁用于任何商业盈利行为。
This project is a port of the DOOM engine for the Youdao Dictionary Pen 2, developed based on the PureDOOM single-header library. The original image is slightly cropped at the top and bottom to fit the 320x170 screen.
This project uses an OTG keyboard for control. Use the arrow keys (↑↓←→) for movement, number keys for weapon switching, Ctrl to fire, Left Shift to run, Esc for the menu/pause, and Space to open doors, etc.
Make sure you have the aarch64-linux-gnu-gcc cross-compilation toolchain installed on your development machine (e.g., Debian/Ubuntu).
Execute the following command in the directory containing PenDOOM.c and PureDOOM.h:
aarch64-linux-gnu-gcc -static -O2 -s -o PenDOOM PenDOOM.c -lmPlace the compiled PenDOOM binary and your game WAD file in the same directory, grant execution permissions, and run it.
chmod +x PenDOOM
./PenDOOM -iwad your_game.wad📄 License & Acknowledgments
