【问题描述】:
所以我正在尝试编写一个基于 tile-grid 的游戏,并想出了一个非常不寻常的解决方案。我用 JLabels 填充了一个 2D JPanel 数组,其中一个 ImageIcon 作为平铺。到目前为止一切正常,但我没有找到任何方法来主动渲染它。 我尝试了一些在 Internet 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 或类似的东西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”
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;
}
}
【问题讨论】:
-
(在这里搜索)使用 Swing Timer 而不是被 Thread.sleep(int) 阻塞的 Runnable
