摇摆动画暂停和恢复

屠夫的扫帚

我想增加暂停/恢复游戏的可能性。不幸的是，我的解决方案仅暂停游戏，但不恢复游戏（当我单击“恢复”按钮时，什么也没有发生-图像仍然静止）。我还尝试了调用wait / notify方法thread，但也没有成功-我得到了Exception in thread "AWT-EventQueue-0" java.lang.IllegalMonitorStateException。进行暂停/恢复的最佳解决方案是什么？

游戏循环

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);

}
