Dragons Arena is online warfare game between computer-controlled dragons and hundreds of virtual knights (avatars or real-life humans). This game was initially developed as a labwork assignment in TU Delft's IN4391 Distributed Computing Systems course. The course was scheduled in Q3 of academic year 2017/18.
Dragons Arena employs Trailing State Synchronization [^1] algorithm to synchronize action messages between peer-to-peer servers.
The comprehensive design of this game is available in the design document.

We have at most 5 mirrored server components.
Various parameters can be configured in common/settings.py.
All of the commands below should be run from the root directory of dragonsarena.
For starting the first server:
python -m server.run_server 1
Preferably in another session, start the second server:
python -m server.run_server 2
For starting a bunch of dragon and human bots plus an additional bot with gui
./battle.sh
Emergency stop command to stop the game (hopefully not needed), tested in Mac OS, might need some mods in other OS
./unbattle.sh
Other than that, to start an observer manually we can use this command:
python -m client.Observer <idx of server_list>
example:
python -m client.Observer 0
To start a human player manually:
python -m client.run_client <player_type> <player_id> <idx of server_list>
example:
python -m client.run_client human id_5 1
To start a dragon player manually:
python -m client.run_client dragon
