Method Detail

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

heuristic

public double heuristic(GamePlay game,
                        GameMove move,
                        int[] role)

this heuristic is basically counting pieces, but as long as the game is not over, it weights the pieces differently according to their potential for a final win. Following this strategy, corner tiles (as they're not alterable anymore) are rated the highest, and border pieces are also rated higher than others.
