All Implemented Interfaces:

Player, Serializable

public class WSPlayer
extends TemplatePlayer

WSPlayer adds AI to the WolfsheepGame; can play both, wolf and sheep. Note: It seems that for the sheeps to win, the game level needs to be set to 7 or higher. If the sheeps move with sufficient intelligence, they cannot loose; the wolf can only win based on mistakes of the sheeps. Also, if the level is set high, the wolf tends to play too defensively (as it anticipates the right move from the sheep that won't let it get through, anyway), so if you want to play against the wolf, set the level lower to make it play more dangerous.

canPlayGame

public boolean canPlayGame(GamePlay game)

Description copied from interface: Player

canPlayGame() returns true only if the Player provides an applicable heuristic for the type of game given. This way, a player can control whether it can a game.

 //Example:
 if (game instanceof MyGameClass) return true; else return false;
 // or:
 if (game.getClass() == myFavoriteGame.getClass()) return true; else return false;
 

setRandomSeed

public void setRandomSeed(long seed)

if seed = 0, randomization is disabled

selectMove

public GameMove selectMove(GamePlay game,
                           int[] role,
                           int level,
                           long milliseconds)

overridden to provide a sensible opening that doesn't suffer from the horizon effect
