Im trying to make admin commands that uses shortcuts to find player but its giving error whenever I try to execute command. Heres script:
function findPlayer(victim)
for i,v in pairs(game.Players:GetChildren()) do
if #victim < 3 then
print("Need more characters than 3 to find player.")
else
local lowname = v.Name:lower()
if lowname:sub(1,#victim) == victim then
if #v > 1 then
print("Enter more characters to find one player.")
else
return v.Name
end
else
print("Could not find existing player.")
end
end
end
end

Whats wrong?
Well it's in the error. "Attempt to get length of a local v, a userdata value."
You're trying to get the length # of variable "v" but its a userdata and has no __len metamethod set. http://lua-users.org/wiki/MetatableEvents
If we look through the code its right here where v is being defined.
for i,v in pairs(game.Players:GetChildren()) do
In this case the value of v is reference to a player.
The error occurs here if #v > 1 then for the reason that I described above.
Note
Roblox uses a datatype called "userdatas" for their instances. More information linked here. https://www.lua.org/pil/28.1.html
Solution
Use the name of v and then compare the length of that to 1 with your condition.
if #v.Name > 1 then
--// code
end
