Minecrab is a game in which players write bytecode to fight each other on a 2D map.
Each player submits two files, bytecode and memory, which are used to created the init process of the user. After all init processes are created, they are on their own and the players have no control over them. Processes can create new processes, mine resources, attack other players' processes, etc. to win the game. Try to make the best AI fighter!
Processes run on a specially crafted instruction set and can interact with various game components with system calls.
A game consists of several ticks. In each tick, every process is run for a certain number of cycles. Every process has a finite number of ticks that it can live for, and a player leaves the game as soon as their init process dies. The game continues until every player has left.
When the game ends, players are ranked according to their scores. A player gains score when one of their processes survives for a tick, or when the game ends and they have leftover cryptocurrency.
For more details, read the files in the docs folder. Note that documentation may contain inaccuracies. When in doubt, check the code.
Write a good AI program and assemble it into a bytecode file (The assembler tool might be useful.) You also need to prepare an initial memory file for the program. Both files must be exactly 65536 bytes, otherwise it is undefined behavior.
Then run the game as described in game setup, and sit back and watch all the processes fight!
