如何在Lua中重复代码？

Question

这是我第一次编写的代码，因为我刚刚开始，所以我不确定是否有任何内容正确缩进。但我想要一种能够重复文本的方式，但我不知道如何去做。

print("Hey there. I want to play a game.") 
    print("Tell me your name") 
    print("Type your name") 
    name = io.read() 
    print("Oh, what a nice name. I was gonna call my kid the same") 
    print("Ok. So as you can see, there are no ligths here. It's all dark. You have three choices. Go west, go east, go north.") 
    print("To go North, type 'n'. To go East, type 'e'. to go West, type 'w'.") 
    repeat 
    direction = io.read() 
if direction == "w" then 
    print(" You see a light switch.") 
    print(" type 'switch'to turn on the switch.") 
    print(" type 'go_back' to turn around") 

    best = io.read() -- This is where i want it to be able to repeat 
    end 
    if best == "switch" then 
      print(" The light goes on.") 
       print(" As the light glows stronger, you see someone standing infront of you") 
       print("Before you know it, he slits your throat. Want to try again?") 
       print("Press enter to try again") 
       try_again = io.read() 
    best = io.read() 


     direction = io.read() 

elseif best == "switch" then 
     print(" The light goes on.") 
       print(" As the light glows stronger, you see someone standing infront of you") 
       print("Before you know it, he slits your throat. Want to try again?") 
       print("Press enter to try again") 
       try_again = io.read() 
       end 
       end 
       until best ~= "go_back" -- to repeat the code up above 

Answer 1

要多次执行一段代码，您可以使用所谓的控制结构。

while EXP do块end

repeat块until EXP

for EXP do块end

或goto标签声明。

请阅读如何使用它们的参考。 http://www.lua.org/manual/5.3/manual.html#3.3.4

您可以将您的代码块放入其中一个控制语句中，也可以将其放入一个函数中，然后将其放入其中一个控制语句中。或者您只需手动多次调用该函数。

您打算重复的代码最好放入函数中。

我建议你做简单的Lua教程，并阅读Lua语言参考手册和Lua编程。两者都可以在www.lua.org
