Design: Behaviour

How should each key entity/component behave?

Describe the lifecycle or key states of major components:

• Lobby Service:
  • e.g., States: Waiting, Starting, In Progress. Transitions based on player actions (join, leave, ready) and creator actions (start).
  • (UML State Diagram for Lobby)

    stateDiagram-v2
        [*] --> Waiting: Lobby Created
        Waiting --> Waiting: Player Joins/Leaves
        Waiting --> Starting: All Ready & Start Triggered
        Starting --> InProgress: Auction Service Confirms Start
        InProgress --> [*]: Game Ends / Lobby Deleted
        Waiting --> [*]: Lobby Deleted
        Starting --> Waiting: Start Aborted

• Auction Service (Game State):
  • e.g., States: WaitingForPlayers, Selling, Bidding, RoundEnd, AuctionEnd. Transitions based on timers, player actions (sell, bid), and events (lobby-started).
  • (UML State or Activity Diagram for Auction Round)
• Player within Auction:
  • e.g., States: Connected, Disconnected, Selling, Bidding.

Rationale:

Explain why these state models were chosen to manage the game flow and service lifecycles.
