Lobby Service: Behaviour

Lobby Lifecycle

The lobby entity transitions through these states:

• Waiting: Lobby created, waiting for players.
• InProgress: The game starts, and the lobby is in-progress.
• Completed: Game ends successfully.

These are the following rules for the lobby lifecycle:

• The lobby is created by the creator.
• Players can join or leave a lobby if it is not full or already in-progress.
• The lobby can be started by the creator if all players are ready.
• The lobby can be deleted by the creator at any time.
• If players leave the lobby and only one player remains (the creator), the lobby is deleted.
• If the lobby is deleted, all players are removed.
• If the game ends successfully, the lobby is marked as completed.

Player States in Lobby

• Ready: Player is ready to start.
• Not-Ready: Player is not ready.

The creator does not have a ready state, as they are always ready to start the game.

Stateful lobby management allows for robust handling of player readiness, joining/leaving, and smooth transition to gameplay.
