Show HN: 3D shooter in your terminal using raycasting in Awk
Bring some old-school fun to your terminal! Explore the dungeon and shoot monsters in this pseudo-3D game inspired by the classic Wolfenstein 3D and Doom.
gawk -f awkaster.awk
You need gawk version >= 4.0.0
Your objective is to navigate the map and activate exit elevator, killing hoards of monsters in the process.
- WASD — movement
- p — shoot
- num 1–4 — change color mode (4 is my favorite)
- x — activate elevator (arrives after 1000 moves)
By default game resolution is 64x48 “pixels”, which are just a pair of ASCII symbols. That means your terminal needs to be at least 128 chars wide. You may change variables w and h to your liking.
Wall rendering is done using ray casting. Monsters and projectiles are added after that as sprites. Ray casting is a simple rendering algorithm that doesn’t require any 3d modeling or complex computation.
