我遇到问题,我的JFrame不断闪烁白色和黑色,但我只将颜色设置为黑色。我认为它与while(running){}位有关。JFrame屏幕闪烁白色和黑色
它只是永远变成白色和黑色,直到我关闭它。我真的不知道发生了什么事。我只是开始使用JFrame,所以我确信我只是放了一些错误的代码。
public class Game extends Canvas implements Runnable {
private static final long serialVersionUID = 1L;
public static int width = 300;
public static int height = width/16 * 9;
public static int scale = 3;
public static boolean running = false;
private Thread thread;
private JFrame frame;
public Game() {
Dimension window = new Dimension(width * scale, height * scale);
setPreferredSize(window);
frame = new JFrame();
}
public synchronized void start() {
running = true;
thread = new Thread(this, "Display");
thread.start();
}
public synchronized void stop() {
try {
running = false;
thread.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
public void run() {
while (running) {
render();
}
}
public void update() {
}
public void render() {
BufferStrategy buffer = getBufferStrategy();
if (buffer == null) {
createBufferStrategy(3);
return;
}
Graphics g = buffer.getDrawGraphics();
g.setColor(Color.BLACK);
g.drawRect(0, 0, getWidth(), getHeight());
g.dispose();
buffer.show();
}
public static void main(String[] args) {
Game game = new Game();
game.frame.setResizable(false);
game.frame.setTitle("Game");
game.frame.add(game);
game.frame.pack();
game.frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
game.frame.setLocationRelativeTo(null);
game.frame.setVisible(true);
game.start();
}
}

@byxor它说我的帖子主要是代码,所以我不能这样做... – GoldShovel
是啊,有一种叫做[MCVE](http://stackoverflow.com/help/mcve)的东西,你应该试着提供。这个“不垃圾邮件代码”规则有助于提高问题的质量。 – byxor
