Question

在我的lua程序中，我想在继续操作之前停下来并要求用户确认。我不知道如何停止并等待用户输入，怎么办呢？

Answer 1

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

Answer 2

查看io库，默认情况下将标准输入作为默认输入文件：

Answer 3

我使用过这样的代码。我将以一种可行的方式输入：

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

尝试使用以下代码

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

从我已经完成的lua（不是很多），我要说如果你使用string.sub，使用大写和小写字母是多余的。

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

这应该有效。
