C＃數組沒有保存數據

Question

我正在嘗試爲基於這個algorithm的項目創建一個地下城發電機。我已經把所有東西都弄下來了，但是我的數組（圖1）似乎並沒有因爲某種原因持有地圖數據。我使用三種類型的數據來確定地圖中的單元格是空的（0），角色可以放置的空間（1），走廊（2）還是牆壁（3）。

我已經有點卡住這部分，所以任何幫助表示讚賞！

編輯：問題是地圖對象沒有在圖1所示的循環中存儲數據。對不起，太模糊了。

（圖1）

 for (int i = 0; i < roomList.Count; i++) 
     { 
      for (int x = roomList[i].X; x < (roomList[i].X + roomList[i].W); x++) 
      { 
       for (int y = roomList[i].Y; y < (roomList[i].Y + roomList[i].H); y++) 
       { 
        map[x, y] = 1; 
       } 
      } 
     }

在for -loop你在哪裏填充roomList，你沒有實例化一個新Room每一次。你只是操縱同一個對象並將其重新添加到列表中，所以roomList將只包含許多對同一對象的引用。嘗試從您的DungeonGenerate類取出room字段並使用一個局部變量來代替：

for (int i = 0; i < amountOfRooms; i++) 
{ 
    bool ok = false; 
    do 
    { 
     var room = new Room(); 
     ... 
     roomList.Add(room); 
    } while (!ok); 
}
