local Players = game:GetService("Players")

local function StartsWith(String, Start)
    return String:sub(1, #Start) == Start
end

local function FindPlayer(Name)
    for i, Player in pairs(Players:GetPlayers()) do
        if StartsWith(Player.Name:lower(), Name:lower()) then
            return Player

    return nil

print(FindPlayer("don"))

I am trying to find Donzee_Boi in players with only typing don as seen above, but it prints nil! Help!

Have you tried debugging your code with print statements?

Yes,

local Players = game:GetService("Players")

local function StartsWith(String, Start)
	print(String:sub(1, #Start) == Start)
    return String:sub(1, #Start) == Start
end

local function FindPlayer(Name)
    for i, Player in pairs(Players:GetPlayers()) do
		    if StartsWith(Player.Name:lower(), Name:lower()) then
			print(StartsWith(Player.Name:lower(), Name:lower()))
            return Player
        end
    end
    
    return nil
end


print(FindPlayer("don"))

I put my code as that and it only printed 1 thin which was nil, and the source was to print(FindPlayer("don"))

I recommend making your Player into lowercase player.

So say for i, player instead of for i, Player and then change the code below to lower player too

That didn’t help. Sorry. Any other ideas?

Is this ran from a server script? If so, is the function called first thing in the script? You may not be present in the game by the time the function is called, try yielding the script for a second or two before printing the function.

Along with what @GalaxyGourmet said, you could try doing return Player.Name inside of the FindPlayer function and I am also curios to know what your print(StartsWith(Player.Name:lower(), Name:lower())) yields or is that what is yielding nil?

Returning the name changes almost nothing. When you print an instance, it’s name shows up in the output. None of the functions seem to yield, and StartsWith() seems to work.

local UserText = script.Parent.username.Boxx

function SetUser(player)
	print(player)
end
UserText:GetPropertyChangedSignal("Text"):Connect(function()
    if string.len(UserText.Text) ~= 0 then
        local found = false
        local username = ""
        for _,v in pairs(game.Players:GetPlayers()) do
            if string.sub(v.Name,1,#UserText.Text) == UserText.Text then
                found = true
                username = v.Name
            end
        end
        
        if found then
            SetUser(game.Players:WaitForChild(username))
        else
            SetUser(nil)
        end
    else
        SetUser(nil)
    end    
end)

Thats a new script someone gave me and it works! Just how do I make it lowercase, so if someones name is in capital letters, and I type it in lowercase, it still detects it.

Use string.lower(str) to get the text lowercased.

local UserText = script.Parent.username.Boxx

function SetUser(player)
	print(player)
end
UserText:GetPropertyChangedSignal("Text"):Connect(function()
    if string.len(UserText.Text) ~= 0 then
        local found = false
        local username = ""
        for _,v in pairs(game.Players:GetPlayers()) do
            if string.sub(string.lower(v.Name),1,#UserText.Text) == string.lower(UserText.Text) then
                found = true
                username = v.Name
            end
        end
        
        if found then
            SetUser(game.Players:WaitForChild(username))
        else
            SetUser(nil)
        end
    else
        SetUser(nil)
    end    
end)

This works! Thanks everyone!
