Known Client Issues

  • Appears best with a dark terminal background
  • The refresh rate is quite high, so you'll need a low latency connection to the server to play effectively (in essense, you want your latency to be lower the game speed - which has a default of 40ms/tick).
  • Only works on operating systems with braille unicode characters (e.g. "⠶" and "⠛") installed. Operating systems lacking this character set will cause the walls to render as the missing glyph (square or diamond).

systemd

Create a /usr/lib/systemd/system/tron.service file:

[Unit]
Description=ssh-tron

[Service]
ExecStart=/path/to/my/ssh-tron -p 22 --join-address tron.company
Restart=always
RestartSec=3

[Install]
WantedBy=multi-user.target

Then:

systemctl enable tron
systemctl start tron

Todo

  • Support multi-core (Fix race conditions)
  • Optimise game calculations
  • Optimise network
  • SPACE to invert colours
  • Add "kills" option (end the game once someone reaches kills)
  • Add "all players reset on any death" option.
  • Extract code to produce a generic 2D multi-player game engine
    • Bomber man
    • Dungeon explorer
