io.write每次打印相同的東西？

Question

我對lua和一般編程非常陌生，目前正在制定一個基本程序來熟悉if/else/elseif和i/o。

基本上，它會問你是否是男孩或女孩，然後打印你的相應內容。

雖然我有一個問題，那就是每次運行程序時，都會打印出你是男孩。

對不起，如果我是一個白癡，任何幫助表示讚賞！

代碼如下;

io.write("Hello, are you a boy or a girl?\n") 
answer = io.read() 
if answer == "boy" or "Boy" then 
io.write("Oh, so you're a boy, huh?") 
elseif answer == "girl" or "Girl" then 
io.write("Oh, so you're a girl, huh?") 
else 
io.write("Wow, i've never heard of an "..answer.." before!\n") 
end 

Answer 1

嘗試

io.write("Hello, are you a boy or a girl?\n") 

answer = io.read() 

if answer == "boy" or answer == "Boy" then 
    io.write("Oh, so you're a boy, huh?") 
elseif answer == "girl" or answer == "Girl" then 
    io.write("Oh, so you're a girl, huh?") 
else 
    io.write("Wow, i've never heard of an "..answer.." before!\n") 
end

說明

Docs說：

析取操作，或者如果這個值是零和虛假不同返回第一個參數;否則，或返回其第二個參數。

步驟如果答案== 「女孩」：

1. answer == "boy" or "Boy"
2. false or "Boy"
3. "Boy"
4. 字符串被視爲真正的 - >執行，如果

Answer 2

嘗試更換這個：

if answer == "boy" or "Boy" then 

有了這個：

if answer == "boy" or answer == "Boy" then 

而對於其他情況類似。
