一个好的方法可能是使用这样的方法：
init（应调用一次，仅限浏览器）。设置任何常见的GUI元素并调用startNewGame()方法。start（在用户恢复浏览器时调用）。取消暂停操作（暂停在stop中）并继续游戏。 stop暂停当前游戏。startNewGame()设置初始生活，片段/字符布局，得分等。当用户想要开始新游戏时，也请致电startNewGame()。
答案 1 :(得分：2)
我知道这是一个老问题。
但上面的小程序格式似乎是个问题。我会使用一些基本的东西，以便更多地控制applet。
＆＃34;在我看来，使用一段时间（真实）绝不是一个好选择＆＃34;
public class TestAppletCycle extends JApplet implements Runnable {
private Thread thread;
private boolean running;
@Override
public void init() {
// Init Game
}
@Override
public void start() {
if(!running) {
running = true;
thread = new Thread(this);
thread.start();
}
}
@Override
public void run() {
while(running) {
// Game Loop
}
}
@Override
public void stop() {
logger.log(Level.INFO, "TestAppletCycle.stop();");
if(running) {
running = false;
try {
thread.join();
} catch(Exception e) {
}
}
}
@Override
public void destroy() {
// Clean Up Game
}
}
现在要重新启动applet，您只需要停止并启动applet。
