我目前正在制作迷宫游戏。播放器完成，地图也正常运行。我现在遇到的问题是，我可以使面板完全将地图包含到我的框架中，但我无法使播放器位于地图上方。当我使用JLayeredPane时，播放器不会显示，而当我不使用它时，播放器将位于地图下方。我有以下课程：
我在哪里制作地图和框架的班级：
import javax.swing.*;
import java.awt.*;
public class Speelveld extends JFrame {
private int x = 0;
private int y = 0;
private Speler speler;
private JPanel panel;
private JLayeredPane layeredPane;
private int[][] map = {
{5, 5, 3, 3, 3, 5, 0, 5, 0, 5},

{5, 4, 5, 5, 4, 5, 0, 5, 0, 0},
{0, 5, 0, 0, 5, 0, 5, 0, 0, 0},
{0, 4, 6, 0, 5, 0, 0, 0, 0, 6},
{0, 0, 6, 0, 0, 0, 0, 0, 5, 2}
};
private Vakje[][] vakjes = new Vakje[10][10];
public Speelveld() {
createComponents();
setTitle("Sleutel Barricade");
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
public void createComponents() {
panel = new JPanel();

layeredPane = getLayeredPane();
this.setSize(400,400);

panel.setSize(300,300);
layeredPane.add(panel, new Integer(1));
layeredPane.add(speler, new Integer(5));
this.setVisible(true);
}
public void vakjesAanmaken() {
int X = 0;
int Y = 0;
for (int i = 0; i < map.length; i++) {
for (int j = 0; j < map[0].length; j++) {
Vakje vakje;
switch (map[i][j]) {
case 0 :
vakje = new Barricade(20,X ,Y);
vakjes[i][j] = vakje;
break;

default:
vakje = new LeegVakje(X,Y);
vakjes[i][j] = vakje;
}
}
}
}
public void paint(Graphics g){
super.paint(g);
g.translate(50,50);
for (int i = 0; i < vakjes.length; i++) {
for (int j = 0; j <vakjes[0].length ; j++) {
panel.add(vakjes[i][j]);
}
}
}
public boolean mogelijkeStapRecht(int X,int Y){

我在其中创建播放器的班级：
import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.image.BufferedImage;
public class Speler extends JComponent {
Speelveld speelveld;
private int zak;
private int XCoordinaat;
private int YCoordinaat;
private int dx;
private int dy;
private int x = 0;
private int y = 0;
Image square = new BufferedImage(30, 30, BufferedImage.TYPE_INT_RGB);
public Speler(){
addKeyListener (new KeyAdapter()
{
public void keyPressed(KeyEvent e)
{
int key = e.getKeyCode();
if (key == KeyEvent.VK_LEFT) dx -= 30;
if (key == KeyEvent.VK_RIGHT) dx += 30;
if (key == KeyEvent.VK_UP) dy -= 30;
if (key == KeyEvent.VK_DOWN) dy += 30;
repaint();
}
});
initVeld();
}
void initVeld()
{
setFocusable(true);
}
public void oppakkenControleren(Sleutel sleutel) {
if (YCoordinaat == sleutel.getYCoordinaat() && XCoordinaat == sleutel.getXCoordinaat()){
zak = sleutel.getPincode();
}
}
public int getXCoordinaat(){
return XCoordinaat;
}
public int getYCoordinaat(){
return YCoordinaat;
}
public void setXCoordinaat(int XCoordinaat) {
this.XCoordinaat = XCoordinaat;
}
public void setYCoordinaat(int YCoordinaat) {
this.YCoordinaat = YCoordinaat;
}
public void paintComponent(Graphics g){
super.paintComponent(g);
drawSquare(g);
}
public void drawSquare(Graphics g)
{
Graphics2D g2d = (Graphics2D) g;
g2d.drawImage(square, dx + getXCoordinaat(), dy + getYCoordinaat(), this);
}
}
答案 0 :(得分：0)
在确定布局管理器之前设置所有大小。
最后一次调用您的方法（将面板设置为可见后）。
