io.write每次打印相同的东西？

Question

我对lua和编程非常陌生，目前我正在制作一个基本程序来熟悉if / else / elseif和i / o。

基本上，它会询问你是男孩还是女孩，然后相应打印出来。

虽然，我有一个问题，每次我运行程序时，它总会打印出你是男孩。

对不起，如果我是白痴，我们非常感谢您的帮助！

代码如下;

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

尝试

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

解释

Docs说：

  

如果此值与nil和false不同，则析取运算符或返回其第一个参数;否则，或返回其第二个参数。

如果回答==“女孩”的步骤：

1. answer == "boy" or "Boy"
2. false or "Boy"
3. "Boy"
4. 字符串被视为true - ＆gt;执行if

Answer 2

尝试替换它：

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

有了这个：

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

与其他案件类似。
