How to check if it's a number value?
So for instance, i have this:
game:GetService("Players").randomplayer.Chatted:Connect(function(msg)
if msg == "range" then
end
end)
How would i check if after the range, it's a number value and what number it is?
I think it's something to do with using dots like "range" .. something i don't know though..

don't use :connect, its deprecated, use :Connect instead cmgtotalyawesome 1418 — 6y

you could use string.sub and convert to unicode/ascii and check if it's within the range 48 to 57. turtle2004 167 — 6y

also, tonumber() does not check if it's a number, it just converts a string to a number. So if they don't say a number it will cause an error. turtle2004 167 — 6y

local playerId = "1234567890" local newPlayerId = tonumber(playerId) print(newPlayerId) >>>123456789 turtle2004 167 — 6y

i would use string.sub
game:GetService("Players").randomplayer.Chatted:Connect(function(msg)
if string.sub(msg, 1, 5) == "range" then
local num = tonumber(string.sub(msg, 6,#msg))
end
end)
also .. is used for "concatenating" string together
print("Hello " .. "World")
>Hello World
