Can I get an example?
I’m still confused.
You can find a lot of examples online with a quick Google search:
Example:
for word in string.gmatch("Hello Lua user", "%a+") do print(word) end
Returns
Hello
Lua
user
Source: lua-users wiki: String Library Tutorial
Hope this helps.

string.gmatch returns the next capture from a string each time it is called. You can set what you want to be captured each time using string patterns. Here is a quick example:
local String = "Hello this is a string"
local Match = string.gmatch(String,".") -- The second argument in this is the string pattern
print(Match()) -- Prints the next capture. In this case it will be "H"
print(Match()) -- Prints the next capture. In this case it will be "e"
In the example above, each timeMatch() is called it will return the next letter in the string.

How would i get the index number from the loop? Like you’d see on normal for loops.
for index, child in ipairs(Map) do
print(index)
end
Count it yourself.
local i = 0
for word in string.gmatch("Hello Lua user", "%a+") do
i = i + 1
print(i, word)
end

Thanks, i was just hoping there was an index variable somewhere in the loop that i didn’t know about.
