有没有比在 Java 中使用 imageIcon 数组更高效的方式来遍历动画图像？

Question

我正尝试在 JPanel 上为我正在构建的游戏制作海鸥图像动画。动画效果很好，它看起来像我想要的那样，但是当我单击播放按钮将卡片切换到下一个 JPanel 时，（有一个由包含此面板的 JFrame 控制的播放按钮将卡片更改为另一个 JPanel，这个动画进行时滞后）它在动画运行ning 时滞后。运行我的动画有没有比像我现在这样循环 ImageIcon[] 更友好的方式？

public class StartPanel extends JPanel implements ActionListener{
    
    Image gull;
    
    Timer timer;
    ImageIcon[] seagullAnimation = new ImageIcon[9];
    int counter = 0;
   

StartPanel(){
    seagullAnimation[0] = new ImageIcon(getClass().getResource("gullBlink0.png"));
    //Here I add the rest of the images in the same fashion

    timer = new Timer(13, this);
    timer.start();
    setPreferredSize(new Dimension(500,500));

}
@Override
protected void paintComponent(Graphics g) {
    super.paintComponent(g);

    //Iterates through the Gull Blink images and set the proper image
    if(counter >=8){
        counter = 0;
        timer.stop();
            try {    
                //Randomizes sleep times to make blink look natural
                Thread.sleep((long) (Math.random() * 5000));
                timer.start();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        
 
    } else {
        counter++;
    }
    gull = seagullAnimation[counter].getImage();

    g.drawImage(gull,10,-450, this);

}

@Override
public void actionPerformed(ActionEvent e) {
    repaint();
}}

修复了延迟。删除了使事件调度线程休眠的代码，这似乎会导致延迟并使用计时器来处理动画之间的暂停。

@Override
protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    setGullFrame();
    gull = seagullAnimation[counter].getImage();
    g.drawImage(gull,10, -450, this);


public void setGullFrame(){
    
    if(counter >=8){
        counter = 0;
        timer.stop();
        timer.setInitialDelay((int) (Math.random() * 5000));
        timer.start();

    } else {
        counter++;
    }

}

有没有比在 Java 中使用 imageIcon 数组更高效的方式来遍历动画图像？

Is there a more performance friendly way to iterate through images for an animation than using an imageIcon array in Java?

java

animation

swing

image

paintcomponent
