Simple OpenGL FPS (C + FreeGLUT)

A tiny first-person demo using legacy OpenGL (compat) and FreeGLUT:

• Move with WASD, hold Tab or Q to sprint
• Aim with mouse (captured by default). Press M to toggle capture
• Shoot with Left Mouse or Space. Hit the red cube to score; it respawns
• Press Esc to quit

Build

Requires development packages for OpenGL, GLU, FreeGLUT, and SDL2 (for audio). On Debian/Ubuntu:

sudo apt-get update
sudo apt-get install -y build-essential freeglut3-dev libsdl2-dev pkg-config

Then build and run:

make -C C/fps
make -C C/fps run

If your distro uses different package names, install the equivalents of:

• libgl1, libglu1, freeglut (dev headers)

Notes

• This uses old-school fixed-function OpenGL for simplicity and broad compatibility.
• Mouse is confined via glutWarpPointer; press M if you need to release it.
• SDL2 is used only for simple procedurally generated sound effects (shoot, hit, game over).
