Because control structures in Lua only consider nil and false to be false, and anything else to be true, this will always enter the if statement, which is not what you want either. There is no way that you can use binary operators like those provided in programming languages to compare a single variable to a list of values.

2011年4月3日 · Lua is deliberately lightweight so it does not have a ternary operator. There are a couple of ways to get past this including using the and-or idiom. But I think that is bad for multiple reasons. Mainly because beginners don't understand it though. I suggest using a function:

2024年5月20日 · If you are splitting a string in Lua, you should try the string.gmatch() or string.sub() methods. Use the string.sub() method if you know the index you wish to split the string at, or use the string.gmatch() if you will parse the string to find the location to split the string at. Example using string.gmatch() from Lua 5.1 Reference Manual:

2011年11月27日 · The version 0.4.1, which is available on the main site, contains ssl/https.lua that should be installed into the Lua package path. – Michal Kottman Commented Nov 28, 2011 at 14:02

I don't know Lua so there might be syntax errors, but the overall idea is that you use string.sub method to divide your message into 2 parts: the command part and the info part. If the command part equals to "kill/" , then find the player with the name specified in the info part, and kill him!

In general, if you want a switch statement in Lua, what you ought to be doing is building a table. For your simple case of choice that could be 1, 2, or fail, a simple if statement with a few conditions is sufficient. For more complex cases, a table of functions should be employed:

The Lua idiom for this case is something like this: function listvalues(s) local t = { } for k,v in ipairs(s) do t[#t+1] = tostring(v) end return table.concat(t,"\n") end By collecting the strings to be concatenated in an array t , the standard library routine table.concat can be used to concatenate them all up (along with a separator string ...

2016年1月2日 · ipairs is a Lua standard function that iterates over a list. This style of for loop, the iterator for loop, uses this kind of iterator function. The i value is the index of the entry in the array. The name value is the value at that index. So it basically does a lot of grunt work for you.

2017年4月21日 · I have three local functions that I want to use forever in memory: proxy:PlayerParamRecover(); proxy:PlayerRecover(); proxy:EnableInvincible(10000,true); I'm not sure how to add them in an infinit...
