space-shooter.c is a cross-platform, top-down 2D space shooter written in standard C11 using only system libraries (with system libraries defined as anything included in the C standard library or supported operating systems). space-shooter.c has been tested on Windows 10 and Ubuntu Linux 16.04. This project drew heavy inspiration from Handmade Hero and pacman.c.

The design and architecture of space-shooter.c is described here [WIP].

I am not a professional game developer, nor a professional C programmer, so the design may be unconventional or sub-optimal in many ways. Happy to take feedback from any pros out there!

Windows

• In a shell with cl set up, run build.bat for a debug build or build.bat release for an optimized build.
• Run space-shooter.exe from the build/ directory.

Linux

• Make sure development headers for the Linux kernel, Xlib, glx and ALSA are installed.
  • E.g. on Ubuntu, run the following: sudo apt install linux-libc-dev libx11-dev mesa-common-dev libasound2-dev
• Run make for a debug build or make release for an optimized build.
• Run ./space-shooter from the build/ directory.

I hope to work on a Mac platform layer as soon as I have a Mac machine to work on.

Since this project is intended as a personal challenge, I am not accepting external contributions at this time. I am very open to feedback, however, so feel free to open an issue for anything that needs fixing.
