Java スイング フレームワークを使用するグリッド ベースのゲームを設計しています。2 つの JPanel を含む JFrame がありますが、そのうちの 1 つが 2 つの場所に表示されます。スクリーンショットは次のとおりです。
「Turn 1」と書かれたボタンが配置されたパネルは、グリッドの右側にのみ表示されるはずですが、奇妙なことに左上隅にも表示されます。これが私のコードです：
public class ArenaPanel extends JPanel {
private final GridPanel gp;
private final InfoPanel ip;
private GameManager gm;
private int w, h;
private int cw, ch;
private double tw, th;
private Point p2;
private Point p1;
private int shotWidth;
private Color shotColor;
public ArenaPanel(int w, int h) {
Images.load();
setLayout(new GridBagLayout());
this.w = w;
this.h = h;
GridBagConstraints c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 1;
c.weightx = 0;
c.weighty = 1;
gp = new GridPanel();
gp.setPreferredSize(new Dimension(700, 700));
this.add(gp, c);
c.gridx = 1;
c.weightx = c.weighty = 0;
ip = new InfoPanel();
add(ip, c);
}
public void setGameManager(GameManager g) {
gm = g;
}
public void start() {
Thread t = new Thread(new Runnable() {
@Override
public void run() {
gm.start();
}
});
t.start();
}
public void step() {
Thread t = new Thread(new Runnable() {
@Override
public void run() {
gm.doTurn();
}
});
t.start();
}
public void paint(Graphics g) {
g.setColor(Color.black);
int val = Math.min(getWidth() - 200, getHeight());
gp.setPreferredSize(new Dimension(val, val));
gp.revalidate();
g.fillRect(0, 0, getWidth(), getHeight());
paintComponents(g);
}
private class GridPanel extends JPanel {
public void paint(Graphics g) {
cw = getWidth();
ch = getHeight();
g.setColor(Color.gray);
g.fillRect(0, 0, cw, ch);
tw = (double) cw / w;
th = (double) ch / h;
g.setColor(Color.black);
for (int i = 0; i < w; i++) {
g.drawLine((int) (i * tw), 0, (int) (i * tw), ch);
}
for (int i = 0; i < h; i++) {
g.drawLine(0, (int) (i * th), cw, (int) (i * th));
}
for (int i = 0; i < w; i++) {
for (int j = 0; j < h; j++) {
Robot t = gm.getGrid()[i][j];
if (t != null) {
Point p = expand(i, j);
g.drawImage(t.getImage(), p.x + t.getOffsetX(),
p.y + t.getOffsetY(), (int) tw, (int) th, null);
}
}
}
if (p1 != null) {
Graphics2D g2 = (Graphics2D) g;
g2.setColor(shotColor);
g2.setStroke(new BasicStroke(shotWidth));
g2.drawLine(p1.x, p1.y, p2.x, p2.y);
p1 = null;
p2 = null;
}
}
}

Google と StackOverflow で同様の問題を調べましたが、見つかりませんでした。どんな助けでも大歓迎です。
ありがとう！
