A discrete 2D game on a rectangular grid: towardsdatascience.com/reinforcement-learning-implement-grid-world-from-scratch-c5963765ebff
This is analogous to many traditional board games such as Chess, the concept is very natural and maps well into computer.
The downsides of gridworld games are:
- it is hard to model speed in discrete worlds. When you 10x faster, when do you collide with something else that is also crossing your path?
- they tend to not use vector representations of objects. So to have an object be 10x longer than another one, the naive implementation has to add 10 smaller objects. This becomes untenable as the number of objects increases.
Although Ciro Santilli is a big fan of plaintext files and of Vim, not so for games. Games must be easy to understand since they are just a toy.
Tilesets to the rescue!
There is great beauty here. Great beauty. It's pure terminal poetry.
The most canonical source code Ciro Santilli can find right now is: sources.debian.org/src/bsdgames/
Many of the games are disabled by default on Ubuntu. But we can enable some games and build from source with:
apt-get source bsdgames
cd bsdgames-*
sed -ri '/^bsd_games_cfg_no_build_dirs=/s/ number / /' config.params
./configure
make -jHere we enabled the game number, so now we can:which gives:
number/number 123one hundred twenty-three.We can also "install" it locally with:which puts the games locally under:which you can add to your
make installdebian/bsdgames/usr/games/numberPATH environment variable.Tested on Ubuntu 24.04, bsdgames 2.17.
