Corewar

About

Core War is a 1984 programming game created by D. G. Jones and A. K. Dewdney in which two or more battle programs (called "warriors") compete for control of a virtual computer. These battle programs are written in an abstract assembly language called Redcode.

42 Version

Here's how it looks like:

Corewar Life

We don't use the same set of assembly instructions as the original Corewar and we have some modulo limitations for the read and write ranges.

How to use it ?
  • First you'll need to write a .s file with a set of assembly instructions
    • You can find this set in either corewar.pdf or in corewar_en.pdf
    • Or you can just use one of the many warriors in the resources/champions directory
  • Then you'll have to compile it using the asm binary
  • Then just execute the corewar binary with your warrior(s) as arguments

This was the final project of the Algorithm branch.

The Team

This project was made by these awesome people:

Installation

Just run make -C Corewar fclean && make -C Corewar... enjoy!

Work on OS X El Capitan and macOS Sierra, the ncurse library is used for the viewer.

Usage

Binaries

corewar

./corewar [-d N -s N -v N | -b --stealth | -n --stealth] [-a] <champion1.cor> <...>

  • -a : Prints output from "aff" (Default is to hide it)
  • -d N : Dumps memory after N cycles then exits
  • -s N : Runs N cycles, dumps memory, pauses, then repeat
  • -v N : Verbosity levels, can be added together to enable several
    • 0 : Show only essentials
    • 1 : Show lives
    • 2 : Show cycles
    • 4 : Show operations (Params are NOT litteral ...)
    • 8 : Show deaths
    • 16 : Show PC movements (Except for jumps)
  • -i : Ncurses output mode

asm

./asm [-d champion.cor] | champion.s

  • -d : Reverse compiler
    • Generate an assembly file from a corewar file (.cor)
    • (Comments are lost as well as label)
    • (Default is to generate a corewar file from an assembly file)

Scripts

check_asm

./check_asm.sh [-del] [-exec] [-diff] [-deasm]

  • -del : Delete created files
  • -exec : Execute the script
  • -diff : Execute diff on all compiled files
  • -deasm : Execute the reverse compiler option then execute diff

script_v

./script_v [number of champ 1-4] <champ name> <...>

  • champ name are given without the .cor extension
  • champ have to be placed in the folder resources/champions
