doomcli

doomcli is a tiny ASCII first-person shooter prototype for the terminal.

It exists because of a meme-level question: could we make Doom run in a CLI, even in a basic form? So this project does the honest version of that idea. It is not Doom, it is not a port, and it does not use Doom assets. It is a terminal raycaster that proves the shape of the joke.

Features

• ASCII raycast renderer in the terminal
• WASD movement
• Arrow-key turning
• One enemy sprite rendered in-world
• Space-bar shooting and a simple win condition
• Wall collision
• Tiny status HUD
• No external dependencies beyond Python standard library

Controls

• W / S: move forward and backward
• A / D: strafe left and right
• Left / Right arrows: turn
• Space: shoot
• Q: quit

Run

python3 doomcli.py

If your terminal is small, make it larger for a better result.

Test

python3 -m unittest discover -s tests -v

Why

Because you and I wanted to see whether "running Doom in a CLI" could be turned into something real enough to demo, even if basic. This is that proof-of-concept.
