Is there an easier way to get the message after the space in a string?
As in example, I have a script which detects when players speak, or chat. I want to get their message, but only after the space.
Example:
1 | local message = "Hello dude."-- dude. |
2 |
3 | local message = "/kill all"-- all |
4 |
5 | local message = "I hate hate."-- hate hate. |
I don't want the space included.
This is what I'm doing currently,
1 | > = string.sub(message, string.find(message, "%s"), #message) |
That works, but I feel like it could be simplified.
Thank you!

First, if you use string methods your code becomes a little shorter and nicer. You can also use -1 to mean "end of string" so you don't have to say #message:
1 | message:sub( message:find("%s"), -1) |
But instead, you can use match. You describe a pattern and put () around the pieces you care about.
For example, you can capture everything from the beginning until the first space(s), then everything after the first space(s):
1 | -- ^: start of the string |
2 | -- (%S+) one or more non-space characters |
3 | -- %s+ one or more space characters |
4 | -- (.+) one or more characters |
5 | -- $: end of string |
6 | local before, after = message:match("^(%S+)%s+(.+)$") |
Note that before and after will be nil if the message isn't the right form.
This would break the example into
"Hello dude."-->"Hello"and"dude.""/kill all"-->"/kill""all""I hate hate."-->"I""hate hate."
