I want to write a script that will correctly detect whether there is a period in a string. However, the script detects the first character it finds as a period. Are periods treated differently/weirdly? Any assistance is appreciated.
My code
print(string.match("oof", "."))
What I expect to happen
Output should print nil
What actually happens
Script treats first character it finds as a period
do string.find instead and see if it works
I tried it already. It does not work and returns 1 1 (the start and end indexes of the first character in the string).
print(string.find("oof", "%.")) --> nil
print(string.find("oo.f", "%.")) --> 3, 3
Since according to the documentation, the . parameter means any character.
i think its because it doesnt find it and returns 1 instead
so do this
local result = string.find(msg,".")
if result == "1 1" then
result = nil
end
Periods are a special character (look up special characters to know what those are). To get it to function like a normal period, put a % before it (%.)
Ah, I see. Thanks for the help!
wow i have been outsmarted time to leave
