我正在尝试用Java创建游戏板（国际象棋）的初始状态。但是，当我运行程序时，电路板似乎被翻转了？如果你看一下初始状态方法，这就是我希望我的初始板开始的方式：
public void initialBoardState(){
gameBoard = new int [][]
{{22,23,24,25,26,24,23,22},
{21,21,21,21,21,21,21,21}, //Black pieces
{0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0},
{11,11,11,11,11,11,11,11}, //White pieces
{12,13,14,15,16,14,13,12}};
}
然而，当我运行它时，电路板似乎会像这样翻转：
gameBoard= new int[][]
{{22,21,0,0,0,0,11,12},
{23,21,0,0,0,11,13}
等等..有人可以解释一下吗？整个班级发布在下面：

答案 0 :(得分：1)
从描述问题的方式来看，您似乎只是输入了 x 坐标，您应该输入 y 坐标，反之亦然。所以这只是一个疯狂的猜测，但尝试更改类似的行：
g2d.drawImage(castle_black,a*80, b*80,null);
对此：
g2d.drawImage(castle_black,b*80, a*80,null);
此外，根据this，该方法被声明为public abstract void drawImage(BufferedImage img, BufferedImageOp op, int x, int y)，所以对我来说，似乎你没有很好地使用它，它应该是这样的：
g2d.drawImage(castle_black, null, b*80, a*80);
但我可能错了，因为我没有经验。
