我正在使用 Swing 编写黑白棋游戏,这是一般代码:(该代码段不包括游戏结束/同一玩家再次进入的情况,这只是基本的游戏循环。)
View / Controller :

public class OthelloGUI extends JFrame {
JSquare[][] board;
final int BOARD_SIZE = 8;
OthelloModel model;

public OthelloGUI(OthelloModel m) {
model = m;

/* Window size, etc... */
setLayout(new GridLayout(BOARD_SIZE, BOARD_SIZE));

//add 8x8 buttons to GUI
ActionListener ml = new MoveListener();
board = new JSquare[BOARD_SIZE][BOARD_SIZE];

for (int i = 0; i < BOARD_SIZE; i++) {
for (int j = 0; j < BOARD_SIZE; j++) {
getContentPane.add(board[i][j] = new JSquare(new Point(i, j)));
board[i][j].addActionListener(ml);
}
}
update();
}

void update() {

//update GUI to reflect last move
for (int i = 0; i < BOARD_SIZE; i++) {
for (int j = 0; j < BOARD_SIZE; j++) {
//changes the JButton's text based on who owns it on the model's board
board[i][j].setText(model.getOwner(i, j).view());
}
}

//best place (I think) to have AI move is after the last move is processed
if (model.getCurrentPlayerType() == PlayerType.AI) {

//Computer player finds its next move, and clicks that button
int[] bestMove = GreedyAI.findMove(model);
board[bestMove[0]][bestMove[1]].doCLick();
}
}

static class JSquare extends JButton {
java.awt.Point p;
JSquare (Point p) {this.p = p;}
}

class MoveListener implements ActionListener {

@Override
public void actionPerformed(ActionEvent e) {

JSquare sq = (JSquare) e.getSource();

//places the piece on the model's "board" and flips all applicable pieces
int result = model.placeDisk(s.p, model.getCurrentColor());

if (result == 0) {//move executes successfully
update();
}
//otherwise... (illegal move, game end, same player again, etc...)
}
}
}

enum Owner {
NONE, BLACK, WHITE;

public String view() {
return this == BLACK ? "B" : this == WHITE ? "W" : ""
}
}

如果我启动 Human v Human,此代码执行良好或 Human v AI游戏,但是,如果我开始 AI v AI游戏,GUI 永远不会呈现。我得到了游戏设置的弹出框,以及游戏结束和谁赢的弹出框,但主要 ContentPane板子从不渲染,所以我看不到 AI 做了什么 Action 。

任何想法/建议?

最佳答案

人工智能是自动化的。人类是……不是。

  • 当人类扮演人类时,代码必须等待人类每转一圈。它必须是事件驱动的。
  • 当人类玩人工智能时,人工智能是自动化的,但代码仍然必须等待人类的事件。
  • 但是当 AI 播放 AI 时,整个过程都留给代码,这会导致 EDT 被阻止。

  • 不要阻塞 EDT(事件调度线程)。发生这种情况时,GUI 将“卡住”。见 Concurrency in Swing有关详细信息和修复。
