local humanoidrootpart = game.Players.LocalPlayer.character:WaitForChild("HumanoidRootPart")
local mouse = game.Players.LocalPlayer:GetMouse()
light.Parent = humanoidrootpart
light.Brightness = 0


mouse.KeyDown:connect(function(key)
	if key == "f" then

		
		script.flashlight_on:Play()
		light.Brightness = 5
		

	end


end)
