Anyone want a sprint script? (This is not a question. )

First of all, I apologize if this is against the rules. I'm really not sure.

I am posting this for anyone who might want it. I learned to code by looking at scripts like this. I hope that this would help new scripters.

I will remove this if asked by an admin.

local Speed = 16 -- The speed of the player when not running

local MaxSpeed = Speed * 1.5 -- The speed of the player when running (This can be changed to any number)

local SpeedIncreaseIncrement = 0.01 -- This is the speed at which the players speed increases to MaxSpeed
-- Use range from 0.001 to 1 (1 is instant)

local SprintKey = Enum.KeyCode.LeftShift -- Change "LeftShift" to the key you want to use.

---------------------------- Don't change anything below this line ---------------------------------

local Player = game.Players.LocalPlayer
repeat wait() until Player.Character -- If the script executes before the player has loaded it will break
local Character = Player.Character

local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local Humanoid = Character:WaitForChild("Humanoid") -- Use WaitForChild to prevent errors if the Humanoid isn't loaded

function NumLerp(Start, Finish, Alpha) -- This is to lerp the players speed to max speed
	local X = (Start - (Start - Finish) * Alpha)
	return X
end

local isRunning = false

Humanoid.WalkSpeed = Speed

function Run()
	if not isRunning then
		isRunning = true
		for i = 0, 1, SpeedIncreaseIncrement do
			if not isRunning then break end
			RunService.RenderStepped:wait()
			Humanoid.WalkSpeed = NumLerp(Humanoid.WalkSpeed, MaxSpeed, i)
			workspace.CurrentCamera.FieldOfView = NumLerp(workspace.CurrentCamera.FieldOfView, 80, i)
		end
	else
		isRunning = false
		for i = 0, 1, SpeedIncreaseIncrement do
			if isRunning then break end
			RunService.RenderStepped:wait()
			Humanoid.WalkSpeed = NumLerp(Humanoid.WalkSpeed, Speed, i)
			workspace.CurrentCamera.FieldOfView = NumLerp(workspace.CurrentCamera.FieldOfView, 70, i)
		end
	end
end

UserInputService.InputBegan:connect(function(Key)
	if isRunning then return end -- No need to run if you already are.
	if Key.KeyCode == SprintKey then
		Run()
	end
end)

UserInputService.InputEnded:connect(function(Key)
	if not isRunning then return end -- No need to stop running if your not running
	if Key.KeyCode == SprintKey then
		Run()
	end
