这是我得到的错误:

这是播放器类:
public class player extends D3D
{
int playerX, playerY;
boolean east, west, south, north;
public void setPlayer()
{
playerX = 1; playerY = 1;
east=true; west=false; north=false; south=false;
}
}
这是 D3D 类:
public class D3D extends JFrame
{
player player = new player();
mapgeneration levelmap = new mapgeneration();
boolean ONE, TWO, THREE, FOUR, FIVE;
boolean ONEhighlight,TWOhighlight,THREEhighlight,FOURhighlight,FIVEhighlight;
Timer timer = new Timer(250,new ActionListener() {
public void actionPerformed(ActionEvent evt) {
repaint();
}
});
String tracer;
Image Example = Toolkit.getDefaultToolkit().getImage("images/example.png");
Image Startup = Toolkit.getDefaultToolkit().getImage("images/Startup.png");
Image ButtonHighlight = Toolkit.getDefaultToolkit().getImage("images/ButtonHighlight.png");
public D3D()
{
super();
setSize(342,277);
...
JPanel main = new JPanel()
{
public void paintComponent(final Graphics g)
{
super.paintComponent(g);
timer.start();
g.drawImage(Startup,0,0,this);
...
};
};
add(main);
}
public void init()
{
player.setPlayer();
levelmap.populateGraph();
}
public static void main(String[] args)
{
D3D game = new D3D();
game.setTitle("Dungens:3D");
game.init();
game.setVisible(true);
}
}
我已经研究了几个小时,并将其缩小到您在此处看到的内容。老实说,这可能是我扫视的一些愚蠢的小事。
谢谢你们。
最佳答案
我看到你的问题。您的 Player 类扩展了您的 D3D GUI —— 导致一种疯狂的循环引用。这将导致递归,因为您循环地不断创建玩家和 D3D 对象。
为了证明我是对的,只需运行这个非常简单的代码版本:
public class D3D {
Player player = new Player();
public static void main(String[] args) {
D3D game = new D3D();
}
}
class Player extends D3D {
}
因此,当创建 D3D 对象时,它会创建一个 Player 对象,并且由于它扩展了 D3D,因此它创建了另一个 Player 对象,因为它是一个 D3D 对象,因此又创建了另一个 Player 对象,等等。
但即使它没有引起递归,Player 也不应该扩展 GUI,因为玩家不是 gui;它们是完全不同的逻辑结构。
