Application Suite for the General Game Playing Project;

• A GUI-based GameKiosk (for playing human-vs-computer matches)
• A GUI-based GamePlayer (for running computer players)
• A GUI-based GameServer (for hosting matches)
• A GUI-based GDLValidator (for validating game rulesheets)

Support code for the above.

Getting started is as simple as writing a new player that inherits from the StateMachineGamer class. StateMachineGamer is based on the state machine view of general game playing, in which playing a game is represented as proceeding through a state machine. The underlying state machine, which you can access via getStateMachine() when inheriting from StateMachineGamer, provides methods that you can use to investigate the game being player:

• Each game has a starting state.

  • getInitialState() is the starting state.

• Each state has legal moves for every player.

  • getLegalMoves(state, role) are the legal moves for in .

• Some states are terminal, and in those states "goal" values are defined for every player, indicating whether they won or lost.

  • isTerminal(state) indicates whether a state is terminal.
  • getGoal(state, role) is the goal value for in .

• Given a legal move for each player, you can transition from one state to the next state, after the players make their respective moves.

  • getNextState(state, moves) is the result of making at .

A simple Prover-based state machine implementation is included in GGP Base, so you don't need to worry about the details of converting a game description into a state machine. To write a gamer based on StateMachineGamer, derive your class from players.gamer.statemachine.StateMachineGamer. Applications like the PlayerPanel should automatically recognize your new class and it should appear in their lists of available players right away.

For examples of simple players, see src/player/gamer/statemachine/reflex, where two extremely simple "reflex-based" players are included: LegalGamer and RandomGamer. LegalGamer always chooses the first legal move available, and the RandomGamer always chooses a random legal move.
