How do i make an Armour script?

You can also find ways to make a a certain player only to give the health to. If you want really high health replace the 200 with math.huge. If this helped a rep point is appreciated.

game.Players.PlayerAdded:connect(function(person) person.CharacterAdded:connect(function(char) char:WaitForChild("Humanoid") char.Humanoid.MaxHealth = 200 char.Humanoid.Health = 200 end) end)

You need to include more details on what you want. For example, have you tried looking up solutions, what other pieces of code have you tried etc.

When they are wearing the armour, make it so that it changes their Humanoid's MaxHealth.
