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.
#Running the game
gawk -f awkaster.awk
You need gawk version >= 4.0.0
OS X users must install gawk first. The easiest way to do this is to use Homebrew. Once it has been installed, run the following commands:
brew update
brew install gawk
NetBSD users require gawk. The easiest way to do it is install it with pkgin:
pkgin install gawk
Alternatively install from sources using the pkgsrc framework:
cd /usr/pkgsrc/lang/gawk && make install
OpenBSD users require gawk. The easiest way to do it is install it with pkg_add:
pkg_add gawk
Alternatively install from sources using the OpenBSD ports:
cd /usr/ports/lang/gawk && make install clean
Your machine will now be ready to run awkaster.
#How to play Your objective is to navigate the map and activate exit elevator, killing hoards of monsters in the process.
Controls:
- WASD - movement
- J/L - turn left/right. Hold shift to turn quicker
- spacebar - shoot
- num 1-4 - change color mode
- x - activate elevator (arrives after 1000 moves)
#Adjusting resolution
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.
#Game engine 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.
