Lua - 從用戶那裏獲取命令行輸入？

Question

在我的lua程序中，我想在繼續操作之前停止並要求用戶確認。我不知道如何停止並等待用戶輸入，怎麼做？

Answer 1

看看在io庫，它在默認情況下有標準的輸入爲默認輸入文件：

Answer 2

local answer 
repeat 
    io.write("continue with this operation (y/n)? ") 
    io.flush() 
    answer=io.read() 
until answer=="y" or answer=="n" 

Answer 3

我像這樣的代碼工作。我會在某種程度上鍵入此它將工作：

io.write("continue with this operation (y/n)?") 
answer=io.read() 
if answer=="y" then 
    --(put what you want it to do if you say y here) 
elseif answer=="n" then 
    --(put what you want to happen if you say n) 
end 

Answer 4

我用：

 print("Continue (y/n)?") 
re = io.read() 
if re == "y" or "Y" then 
    (Insert stuff here) 
elseif re == "n" or "N" then 
    print("Ok...") 
end 

Answer 5

嘗試使用如下因素代碼

m=io.read() if m=="yes" then (insert functions here) end

Answer 6

print("Continue (y/n)?") 
re = io.read() 
if re == "y" or "Y" then 
    (Insert stuff here) 
elseif re == "n" or "N" then 
    print("Ok...") 
end 

從我已經完成的lua（不是很多）的角度來說，如果使用string.sub，我會說使用大寫和小寫字母都是多餘的。

print("Continue? (y/n)") 
local re = io.read() 

--[[Can you get string.sub from a local var? 
If so, this works. I'm unfamiliar with io(game 
lua uses GUI elements and keypresses in place of the CLI.]] 

if re.sub == "y" then 
    --do stuff 
if re.sub == "n" then 
    --do other stuff 
end 

這應該工作。
