MqttSnake

An educational/experimental snake-like multiplayer game that uses mqtt

How To Use This

1. Install the necessary libraries pygame and paho-mqtt if not done already. You can run pip install -r dependencies.txt for that. Note that you may want to do that in a virtualenv.
2. run python3 Snake.py to run the game in single player mode. To run it in multiplayer mode, run python3 Snake.py YOURNAME REMOTENAME, while YOURNAME and REMOTENAME are - you guessed it- placeholders for any unique names. It only matters that your counterpart uses the same names in reverse order.
3. Use the arrow-keys on your keyboard to control the snake. Have fun.

TODOs

• Currently the complte remote snake positions are marshalled into json and unmarshalled at the remote player. This might be replacable with a more condensed protocol between the players. For the initial development, it seemed to be the quick-and dirty solution to ensure consistency between the two players.

• The game currently uses the hard-wired public mqtt broker broker.emqx.io, setting the broker via the commandline might be nice to have.

• The frame-rate is limited to reduce latency issues in the game. The original snake becomes faster though as the game progresses.
