我想添加暫停/恢復到我的遊戲的可能性。不幸的是,我的解決方案只是暫停遊戲,但不會恢復(當我點擊恢復按鈕時什麼都沒有發生 - 圖像仍然存在)。我也嘗試在thread
上調用wait/notify方法,但它也不起作用 - 我得到了Exception in thread "AWT-EventQueue-0" java.lang.IllegalMonitorStateException
。暫停/恢復的最佳解決方案是什麼?擺動動畫暫停和恢復

public void run() {
init();
long startTime;
long reTime;
long waitTime;
while (running) {
startTime = System.nanoTime();
int CarPosX = car.zwrocPolozenieX();
int CarPosY = car.zwrocPolozenieY();
update(b, CarPosX, CarPosY);
render(b);
//draw();
repaint();
if(b<4390) {
b=b+szybkoscMapy;
}
reTime = System.nanoTime() - startTime;
waitTime = targetTime - reTime/100000000;
try {
Thread.sleep(waitTime);
}
catch(Exception e) {
}
}
}
public void init() {
if(thread == null) {
thread = new Thread(this);
thread.start();
}
b=0;
running = true;
image = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB);
g = (Graphics2D) image.getGraphics();
map = new Map(levelNumber);
car = new Car(map);
car.setxpos(338);
car.setypos(150);
}
