首先,我知道这是一个混乱,无组织的一堆Lua,但我仍在学习,所以请原谅我。功能和while语句创建无限打印循环
我的问题是: 我在iPad的TouchLua +上运行我的代码,它运行的很顺利,直到我回到tinput = io.read(),无论是输入'attack'还是'run away'I最终会在屏幕上印上“这不是一个有效的命令”,这是无限的。
我认为这是while语句中的get_input()与我已经将tin.read()定义为tinput而不是整个脚本的标准输入之间的冲突。
我可以接受这一点,除了我从中学习的脚本(目前的YouTube视频)没有这样做的事实,我已经比较了两者和功能,以及'如果能够'和他们写的完全一样。
我试图找到答案在谷歌上,视频和原始脚本存储在github上的意见,但我不明白github,但谷歌并没有帮助。
我做了什么错误,或者错过了,或者一般搞砸了......
另外,请原谅我的大量使用的意见,对不起。

如果我的回答有帮助,可否请您将其标记为已接受?如果它仍然处于无限循环状态,我很乐意再看看并相应地编辑我的答案。 –
