批處理如果聲明錯誤

Question

我正在嘗試使批量掃雷，但我有奇怪的錯誤。當我運行該文件時，它會放置5個地雷。然後它穿過其餘的廣場並檢查每個廣場附近有多少個地雷。我的問題是，它只感覺到向東南方向輸出。東南碼與任何其他方向的碼不同。這對我來說非常混亂。似乎沒有其他人有這個錯誤。這是一個輸出示例：

M 0 1 0 0 
0 1 0 M 0 
M 0 M 0 0 
0 0 1 0 0 
0 0 0 M 0 

答案將不勝感激。

Answer 1

您的主要問題是行尾空格。在傳統的set語句中，任何尾部空格都包含在分配的值中，並且"M"和"M "是完全不同的東西，因此如果您有set X=!something!，則分配的值與set X=!something!分配的值不同。

您還有一個問題，在您將X與您的Y混淆。例如，設置W使用X和Y+1完成 - 與設置N相同。這應該是X-1和Y。
