如何让java等待事件?

我正在写一个简单的tictactoe游戏,每个玩家可以是人类或AI。 因此,为了创建一个新的游戏实例,我做到了这一点,我所做的就是:

Player p1=new RLPlayer(world);
gameInstance = new GameInstance(this, p1, new HumanPlayer(this, world), world);

但是,如果我做了类似

的事情
Player p1=new RLPlayer(world);
gameInstance = new GameInstance(this, p1, new HumanPlayer(this, world), world);
Player p2=new RLPlayer(world);
gameInstance = new GameInstance(this, p2, new HumanPlayer(this, world), world);

只玩了1场比赛。我已经想到这是因为对于HumanPlayer来说,它在等待移动输入时停止并且什么都不做,如果之后有代码,它只是跳过它。如何让执行等待输入?或者我的方法完全错了?我有一种感觉。

public class HumanPlayer implements Player {
    private GameGUI gameGUI;
    private TicTacToeWorld world;

    public HumanPlayer(GameGUI gameGUI, TicTacToeWorld world){
        this.gameGUI = gameGUI;
        this.world = world;
    }

    public boolean makeMove() {
        gameGUI.setMoveInputEnabled(true);
        return false;
    }

    public boolean makeMove(int move){ //false means no move made
        if(!world.isMoveLegal(move)) return false;

        world.makeMove(move);
        gameGUI.setMoveInputEnabled(false);
        return true;
    }

    public void observeMove(){
    }

}

仅适用于某些情况。我认为问题出在上面的那个。

public class GameInstance {
    private Player[] players;
    private TicTacToeWorld world;
    private GameGUI gameGUI;


    public GameInstance(GameGUI gameGUI, Player player1, Player player2, TicTacToeWorld world){
        this.gameGUI = gameGUI;
        players = new Player[]{player1,player2};
        this.world = world;

        runGame();
    }

    public void runGame(){
        gameGUI.updateGUI(world.getWorldState());
        while(!world.isGameOver()){
            if(!makePlayerMove())return;
            gameGUI.updateGUI(world.getWorldState());
        }
    }

    public boolean makePlayerMove(){
        int[] state;
        state = world.getWorldState();

        if(players[(state[0]-1)%2].makeMove()){
            players[state[0]%2].observeMove();
            return true;
        }
        else
            return false;
    }

    public void makePlayerMove(int move){ //force move AI OR input human move
        int[] state;
        state = world.getWorldState();

        if( players[(state[0]-1)%2].makeMove(move) ){ //if move was made e.g. AI. Human player would return false;
            gameGUI.updateGUI(world.getWorldState());
            players[state[0]%2].observeMove();
            runGame();
        }
    }
}

答案 0 :(得分:0)

希望你刚才能想到这一点,但仅仅是为了完整性:

您的游戏必须在GUI上运行事件。具体来说,你的AI移动代码必须运行以响应人类玩家移动的点击 - 在ActionLister的actionPerformed方法的实现中。你需要考虑GUI - 按钮和事物 - 的游戏流程。或者更确切地说,您已经在GUI事件上重建了适当的游戏流程。
