How can I get the string after a comma?
For learning purposes, I am creating a script that will create an Instance based on whatever I say.
For example; if I say, "instance/Part, workspace" it will create a part in workspace.
But I don't know how to get everything after the comma.
I also don't know how to make it required to use a comma after they say the instance.
local player=game.Players.LocalPlayer
function newInstance(name, pos)
local instance=Instance.new(name, pos) --name=name of the instance|pos=parent of the insatnce
end
player.Chatted:connect(function(msg)
if string.sub(string.lower(msg),1,9)==string.lower("instance/") then
local ins=string.sub(msg,10,#msg)
local pos --This is where I am confused. This is supposed to get everything after the comma in ins
newInstance(ins)
end
end)

String manipulation
Saviour of the universe
To get everything after the first comma, just match it.
function YourCommasOrYourLife(s)
return s:match("^[^,]+,(.*)$");
end
How does it work?
- The
^makes it start from the start of the string. No good matching it midway. - The
[^,]matches everything that's not a comma. - The
+matches one or more occurrences of the preceding set. - The
,matches a comma. Simple. - The
( )marks a capture, which is the bit the function wants to return. You can have as many of these as you want. - The
.captures anything, and*captures 0 or more occurrences. - The
$makes it go all the way to the end. Pointless in this match because*does it anyway, but hey what is learning without unnecessary additions?

And how would I include this in the script? SimplyRekt 413 — 8y

Just stick the string you want to get the comma bit from into the function. It's really not that difficult, considering this is now skiddie-level implementation implementation. User#6546 35 — 8y

[ For example; if I say, "instance/Part, workspace" it will create a part in workspace. ] Have you tried "instance/Part, game.Workspace" ?
