games.multi_player.state_manager¶
State management interface for multi-player games.
This module provides the base state manager interface for multi-player games, defining the core operations that game-specific state managers must implement. The state manager handles:
Game initialization
Move application and validation
Legal move generation
Game status updates
Phase transitions
Information hiding
Example
>>> from typing import List, Dict, Any
>>> from haive.agents.agent_games.framework.multi_player.state_manager import MultiPlayerGameStateManager
>>>
>>> class MyGameStateManager(MultiPlayerGameStateManager[MyGameState]):
... @classmethod
... def initialize(cls, player_names: List[str], **kwargs) -> MyGameState:
... return MyGameState(players=player_names)

Module Contents¶
- class games.multi_player.state_manager.MultiPlayerGameStateManager¶
Bases:
Generic[T]Manager for multi-player game states.
This abstract base class defines the interface for managing game states in multi-player games. Game-specific implementations must inherit from this class and implement all abstract methods.
- Type Parameters:
T: The game state type, must be a Pydantic BaseModel.
Example
>>> class ChessStateManager(MultiPlayerGameStateManager[ChessState]): ... @classmethod ... def initialize(cls, player_names: List[str], **kwargs) -> ChessState: ... return ChessState( ... players=player_names, ... board=cls.create_initial_board() ... )
- classmethod advance_phase(state)¶
- Abstractmethod:
- Parameters:
state (T)
- Return type:
T
Advance the game to the next phase.
This method should handle phase transitions, including any necessary state updates or cleanup between phases.
- Parameters:
state (T) – Current game state.
- Returns:
Updated game state in the new phase.
- Return type:
T
- Raises:
NotImplementedError – Must be implemented by subclass.
- classmethod apply_move(state, player_id, move)¶
- Abstractmethod:
- Parameters:
state (T)
player_id (str)
move (Any)
- Return type:
T
Apply a move by a specific player.
- Parameters:
state (T) – Current game state.
player_id (str) – ID of the player making the move.
move (Any) – The move to apply.
- Returns:
New game state after applying the move.
- Return type:
T
- Raises:
NotImplementedError – Must be implemented by subclass.
- classmethod check_game_status(state)¶
- Abstractmethod:
- Parameters:
state (T)
- Return type:
T
Check and update game status.
This method should check for win conditions, draws, or other game-ending conditions and update the state accordingly.
- Parameters:
state (T) – Current game state.
- Returns:
Updated game state with current status.
- Return type:
T
- Raises:
NotImplementedError – Must be implemented by subclass.
- classmethod filter_state_for_player(state, player_id)¶
-
Filter the state to include only information visible to a specific player.
This method should implement information hiding, ensuring players only see game information they should have access to.
- Parameters:
state (T) – Current game state.
player_id (str) – ID of the player to filter for.
- Returns:
Filtered game state with only visible information.
- Return type:
Dict[str, Any]
- Raises:
NotImplementedError – Must be implemented by subclass.
- classmethod get_legal_moves(state, player_id)¶
-
Get legal moves for a specific player.
- Parameters:
state (T) – Current game state.
player_id (str) – ID of the player to get moves for.
- Returns:
List of legal moves for the player.
- Return type:
List[Any]
- Raises:
NotImplementedError – Must be implemented by subclass.
- classmethod initialize(player_names, **kwargs)¶
-
Initialize a new game state with multiple players.
- Parameters:
player_names (List[str]) – List of player names/IDs.
**kwargs – Additional game-specific initialization parameters.
- Returns:
A new game state instance.
- Return type:
T
- Raises:
NotImplementedError – Must be implemented by subclass.
