How can I simplify my string manipulation code snippet?
I was having a lot of trouble with this one piece of code that is supposed to fetch the price of items from similarly formatted text labels. While it works now, is there a way to simplify the code? Thanks.
The text being referenced is formatted like this: ItemName: $50
local price = string.sub(script.Parent.Parent.ItemName.Text,
string.sub(string.find(script.Parent.Parent.ItemName.Text, "%$"), 1, 2))
local price = tonumber(string.sub(price, 2))

It looks very simple already. MrLonely1221 701 — 7y

You can simplify it using string.match.
If prices are expected to always be integers, you can do this:
local price = script.Parent.Parent.ItemName.Text:match('%$(%d+)');
However, if it's possible for them to have decimal places (in this example, up to two):
local price = script.Parent.Parent.ItemName.Text:match('%$(%d+%.?%d?%d?)');
Hope this helped.

Thanks a lot. Can you explain exactly what the percentage signs and other special characters do in your argument for match()? Klamman 220 — 7y
