java - 使用 ImageIcon 磁贴在 JPanel 上进行主动渲染？ #Java

Question

所以我正在尝试编写一个基于图 block 网格的游戏，并提出了一个非常不寻常的解决方案。我用 JLabels 填充了 2D JPanel 数组，并将 ImageIcon 作为图 block 。到目前为止一切正常，但我没有找到任何方法来积极渲染它。 我尝试了一些在互联网上找到的主动渲染方法，但它们对我的想法不起作用。您是否有一些想法如何在不将所有内容重写为 Canvas 或类似内容的情况下实现这一点？

这是我的代码:

窗口

public class Win extends JFrame {
private static final long serialVersionUID = 1L;
private BufferStrategy bs;

public Win(int x, int y) {

    this.setSize(x, y);
    this.setVisible(true);
    this.setResizable(false);
    this.setIgnoreRepaint(true);
    this.createBufferStrategy(2);
    setBs(getBufferStrategy());
}

public BufferStrategy getBs() {
    return bs;
}

public void setBs(BufferStrategy bs) {
    this.bs = bs;
}
}

“画图”

public class Field extends JPanel {
private static final long serialVersionUID = 5257799495742189076L;

private int x = 0;
private int y = 0;
private JPanel backPanel[][] = new JPanel[19][19];
private BufferedImage images[] = new BufferedImage[100];
private JLabel image[][] = new JLabel[19][19];

public Field() {

    this.setLayout(new GridLayout(20, 20));
    this.setIgnoreRepaint(true);

}

// Creates Panel Grid & Draws floor
public void setPanels() {
    for (int h = 0; h < 19; h++) {
        for (int w = 0; w < 19; w++) {

            backPanel[h][w] = new JPanel();
            backPanel[h][w].setLayout(new GridLayout(1, 1));

            image[h][w] = new JLabel(new ImageIcon(images[0]));

            backPanel[h][w].add(image[h][w]);

            this.add(backPanel[h][w]);
        }
    }
}

// Loads the Textures
public void getTextures() throws IOException {
    for (int i = 0; i < 1; i++) {
        images[i] = ImageIO.read(new File("texture.png"));

    }
}

public void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.drawImage(images[1], 0, 0, null);

}

public int getY() {
    return y;
}

public void setY(int y) {
    this.y = y;
}

public int getX() {
    return x;
}

public void setX(int x) {
    this.x = x;
}

}

游戏循环

public class GameLoop implements Runnable {

private boolean runFlag = true;

@Override
public void run() {
    Field field = new Field();
    Win window = new Win(640, 640);
    window.add(field);

    try {
        field.getTextures();
    } catch (IOException e) {

        e.printStackTrace();
    }

    while (runFlag) {

        try {
            field.setPanels();
            window.getBs().show();
            Thread.sleep(20);
        } catch (InterruptedException e) {

            e.printStackTrace();
        }

    }

}

public void stop() {
    runFlag = false;
}

}

一些替代方案:

• 打乱组件并执行removeAll()、add()和validate() >如图here .

• 随机播放内容并执行setIcon()，如图here .

无论哪种情况，

• 使用javax.swing.Timer调整动画的节奏，如图 here和 here .

• 考虑使用TexturePaint来填充图标，如图here .
