Humanoid new "health" energy or stamina?

I want to create and assign a variable (Energy) to the humanoid by Script like a (Health). e.g.: Energy / Humanoid / Player

Is possible without Script, however is not displayed in "Game" in the Humanoid object. • Create a variable in StarterGui • Create a variable in StarterPack • Create a variable in StarterPlayer

It's possible? Any suggestion?

Is it possible to create a variable for the Humanoid object per instance?

humanoid = Instance.new ("Humanoid")

(I do not know how it works)

I already spent 10 hours of research and I did not find anything

You cant add a new proppertie to the Humanoid I think but you can add new Values though. Like this below! :

game.Players.PlayerAdded:Connect(function(player)

player.CharacterAdded:Connect(function(character)

local stamina = Instance.new("IntValue")--- AN IntValue is a Value that only has Whole Numbers or Integers

stamina.Parent = character---Set The Parent for the Stamina "IntValue"

stamina.Name = "Stamina"---Set the Name for it

stamina.Value = 100 --- Set the Value for it!

---And Boom! Now you have your new stamina value inside your character! :D

----Now you can refference it by saying "player.Character.Stamina" or "player.Character:WaitForChild("Stamina")"

end)

end)

A simple solution might be to just put a value inside the starterCharacter folder.
