What is another version of game.Players.LocalPlayer for a regular Script?

I'm wondering another way to access a LocalPlayer through a regular script, How would I go about doing this?

game.Players.LocalPlayer.MoneyValue

That's what I'm trying to do only through a Script, How would I accomplish this?

There's no way of doing this with a script without having no input from the player. If you have an input from a player, such as MouseClick, Touched, etc., then you can find the "local player."

One way of doing this is acquiring the name of the player through the event and finding the player.

Example 1

script.Parent.Touched:Connect(function(characterBodyPart)
	local characterName = characterBodyPart.Parent.Name -- Gets the name of the player that touched the object.
	local player = game.Players:FindFirstChild(characterName) -- Finds the player with that name and indexes it as 'player'.
end)

You could also add a remote event in replicatedStorage and a local script in starterGui and call for the server from the individual player's client.

In Local Script

local repStorage = game:GetService("ReplicatedStorage")
local remote = repStorage:WaitForChild("RemoteEvent")
local player = script.Parent.Parent

remote:FireServer(player)

In Server Script

local repStorage = game:GetService("ReplicatedStorage")
local remote = repStorage:WaitForChild("RemoteEvent")

remote.OnServerEvent:connect(function(player)
     player.MoneyValue
end)

Hope this helps
