無法在批處理文件中調用函數

Question

我最近學習了一些教程，並學習瞭如何創建和編程批處理文件。我開始製作一款旨在模擬戰鬥怪物的遊戲。這個遊戲的機制之一是成爲一個已經編程的庫存，你可以從商店購買某些物品並將它們放入你已經可以在戰鬥中使用的庫存中。到目前爲止，唯一的編程級別是教程，只是它的開始。你應該能夠做的是在詢問時選擇一個存貨槽，然後計算機應該運行似乎沒有的庫存功能。出現一些錯誤，然後自動關閉窗口。如果任何人都可以簡單地解釋爲什麼這不起作用，我如何解決它，這將真的幫助我。謝謝：d這裏是我的代碼...

Answer 1

if %~1==rock set %damage%=2 

可能不正確。如果%~1爲空，則會出現語法錯誤。

您試圖set的變量是damage到2. 內容也許這是不正確。如果damage沒有設置在這個時候，你會得到一個錯誤cmd試圖解析set =2

開始>程序>附件和快捷鍵設置自己Command Prompt。

點擊，這將讓你到cmd，然後你可以瀏覽有關通過改變到相應的目錄中cd c:\wherever\your\batch\is，只是運行nameofyourbatchfile運行批處理。

要退出cmd，請鍵入exit並獲得有關命令的幫助type commandname /？

所有acions終止與輸入
