Question

我试图不用Java重新绘制我的窗口。我有：

public void paint(Graphics g) {
        super.paint(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        ball.paint(g2d);

    }

并在主要：

while (true) {
            game.move();
            game.repaint();
            Thread.sleep(10);
        }

我的JFrame是窗口，我尝试了window.setIgnoreRepaint(true);，但没有任何变化。你能帮我个忙吗？谢谢:)）

Answer 1

while (true) {
        game.move();
        game.repaint();
        Thread.sleep(10);
    }

必须替换为

            Timer t=new Timer(10,new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    game.move();
                    game.repaint();
                }
            });
            t.start();

并覆盖内容窗格的paintComponent（）。

Answer 2

super.paint(g)重新绘制窗口 - 您需要删除此行。

public void paint(Graphics g) {
        // super.paint(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        ball.paint(g2d);

    }

使JFrame不重绘
