我在网上找到了一些Java游戏代码,我正在修改它。我将它从JFrame转换为Applet,但是每当我重新绘制屏幕时,我的游戏就开始闪烁。我试过双缓冲但没有区别。为什么我的applet每次刷新都会闪烁?

private void paintDisks(Graphics g) {
try {
for (Disk d : disk)
paintDisk(g, d);
} catch (Exception ex) {
//System.out.println(ex.getMessage());
paintDisks(g); // retry so the disks never not get painted
}
}
private void paintDisk(Graphics g, Disk d) {
if (d == null)
return;
if (diskimg[d.player] == null) {
g.setColor(colour[d.player]);
g.fillOval((int)d.x - 1, (int)d.y - 1, 32, 32);
} else {
g.drawImage(diskimg[d.player],
(int)d.x - 1, (int)d.y - 1,
32, 32, this);
}
}
@Override
public void paint(Graphics g) {
// paint real panel stuff
super.paint(g);
Graphics gr;
if (offScreenBuffer==null ||
(! (offScreenBuffer.getWidth(this) == this.size().width
&& offScreenBuffer.getHeight(this) == this.size().height)))
{
offScreenBuffer = this.createImage(size().width, size().height);
}
gr = offScreenBuffer.getGraphics();
gr.clearRect(0,0,offScreenBuffer.getWidth(this),offScreenBuffer.getHeight(this));
// paint the disks
paintDisks(gr);
// paint the curser ontop of the disks
paintCurser(gr);
g.drawImage(offScreenBuffer, 0, 0, this);
}
@Override
public void run() {
while (true) {
repaint();
try {
Thread.sleep(9, 1);
} catch (InterruptedException ex) {
System.out.println(ex.getMessage());
}
}
}
}
如果您首先将其分解为一个更简单的自包含示例来说明问题,那么您和我们可能会更容易进行调试。 – Ben
