I have a part called "Checkpoint2", and inside it, there is a script with this function
print(string.gsub(script.Parent.Name, "Checkpoint", ""))
called when Touched.
It should print "2" , shouldn't it? too bad, cause it prints "2 1" and I have no idea why... I've tried to make a second string.gsub to remove the " 1" , but then it prints "2 0" ! Can someone see an error here? (the rest of the script is useless)
gsub actually returns two things. First the string, and then how many times it did the replace.
print prints all things returned, so you're seeing both, separated by a tab.
There isn't an error here at all! If you store it to a variable, you'll see that it works normally:
local str, matches = script.Parent.Name:gsub("Checkpoint","")
print(str)
-- 2
print(matches)
-- 1 (the other number you're seeing)

It's kinda weird, but it worked. Thanks.
If you added a comma to the str varialbe and added an matches variable after the comma, if you printed the matches variable, I assume it would print the number of matches it found, correct?
Correct
