这是我的简单迷宫游戏代码。它正在被编译,MazeGame.java和Board.java的类文件正在创建,但不是Player.java和Map.java。代码正在编译时没有错误,但它没有运行。请帮帮我。
//MazeGame.java

f.setSize(450,450);
f.setLocationRelativeTo(null);
f.add(new Board());
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

我不想生气,但你要定义不同的文件夹位置
在某些地方"G://sonali_java//mygane//object.png"
,请查看“mygaNe”
在某些地方"G://sonali_java//mygame//Map.txt"
,请查看“mygaMe”
您确定在加载时不会抛出NullPointerException
吗?

您是否知道可以放置像
这样的代码 public void draw(Graphics g){
g.drawImage(playerImg, getX(), getY(), null);
}
在你的玩家类中,从而让玩家类在绘制玩家并简单地在你的Board绘制方法中调用玩家绘制方法?这也可以用于绘制地图。记得在paint方法中调用draw方法。 还有,这个 ImageIcon img = new ImageIcon(“G:// sonali_java // mygane //object.png”); 检查您的目录位置
