我有一个我正在尝试制作的国际象棋游戏，我正在尝试repaint()在游戏循环中调用我的一个 JFrame 上的方法。这个特殊的 JFrame 显示了每个玩家的总击杀数。我很确定repaint()实际上是在调用它，但由于某种原因，它似乎没有正确更新我的 JLabels，它应该保存每个玩家的击杀数。
这是我的自定义 JFrame 扩展类的代码，其中包含代表杀戮的 JLabel。
private ChessGame game;
private JPanel killsPanel;
private String p1kills;
private String p2kills;
private JLabel kills;
private JLabel p1, p2;
private JLabel p1NumKills = new JLabel();
private JLabel p2NumKills = new JLabel();
//the player's kill values are increasing and registering, just not within the jlabels representing them
public KillsFrame(ChessGame game){
this.game = game;
killsPanel = new JPanel(new MigLayout("", "[center][right][left][c]", "[top][center][b]"));
kills = new JLabel("KILLS");
p1 = new JLabel(game.getCurrentPlayer().getName() + " - ");
p2 = new JLabel(game.getOtherPlayer().getName() + " - ");
//this is the part that should be working but isn't.
//p1kills and p2kills aren't being updated or something.
p1kills = "" + game.getCurrentPlayer().getKills();
p2kills = "" + game.getOtherPlayer().getKills();
p1NumKills.setText(p1kills);
p1NumKills.setText(p2kills);
killsPanel.add(kills, "span");
killsPanel.add(p1);
killsPanel.add(p1NumKills, "wrap");
killsPanel.add(p2);
killsPanel.add(p2NumKills, "wrap");
killsPanel.setBackground(Color.lightGray);
add(killsPanel);
pack();
setTitle("Scoreboard");
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
setResizable(true);
setVisible(true);
setLocationRelativeTo(null);
}
然后我只是在不同类的 main 方法中调用这个框架的 repaint() ：
public static void main(String[] args) throws InterruptedException {
JFrame gameFrame = new ChessMain();
gameFrame.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
gameFrame.pack();
gameFrame.setResizable(true);
gameFrame.setLocationRelativeTo(null);
gameFrame.setVisible(true);
gameFrame.setTitle("Chess X");
LoginFrame loginFrame = new LoginFrame(((ChessMain) gameFrame).getGame());
System.out.println(((ChessMain) gameFrame).getGame().toString());
System.out.println(((ChessMain) gameFrame).getGame().currentPlayer.getName()+ ", it's your turn.");
//this is what creates the kills frame.
KillsFrame kf = new KillsFrame(((ChessMain) gameFrame).getGame());
while(true){
((ChessMain) gameFrame).getGame().run();
kf.repaint();//*************************************
Thread.sleep(1);
}
}
非常感谢任何和所有帮助。
