Java: Laser Mirror Maze Game - Laser exit function fix - 2d arrays, switch case, loops

Question

我正在做一个项目，我在这个游戏中有一个 5x5 的网格，其中有随机放置的镜子，玩家试图通过发射激光并查看它的出口位置或猜测坐标来猜测镜子的位置。

网格看起来像这样：

 ABCDE
T.....F 
S.....G 
R.....H 
Q.....I 
P.....J 
 ONMLK

我被困在如何让 shootLaser() 方法按预期工作。

我想让用户看到激光在什么字母处退出。这是输出产生的：

Enter a letter (A-T) to shoot the laser: A
Shot exited maze at 0

老师给了我小费：

When the laser exits (looping stops) you will need to use the X&Y coordinates (row? Col?) to CALCULATE where it exited… this is the inverse of starting the shot, (where we take ‘C’ and get X=2,y=0, DOWN…)
