How can i do this in a script?

[TafareWoomy (picklepicolo)]

How do you make a script whereas when the players humanoid function is walking a value increases? since i tried doing this with the input began function and it works but its not mobile supported, and i want to be supported for both devices, so how can i do this?
this is the code

local uis = game:GetService("UserInputService")
local walking = false
local stepswalked = 0
local player = game.Players.LocalPlayer
local points = player:WaitForChild("Points")
local multiplier = player:WaitForChild("PointsMultiplier").Value



uis.InputBegan:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.Keyboard then 
		if input.KeyCode == Enum.KeyCode.W then 
			walking = true
			
			while walking == true do 
				points.Value = (points.Value + 1) * multiplier
				wait()
			end
			elseif input.KeyCode == Enum.KeyCode.S then 
				walking = true

				while walking == true do 
				points.Value = (points.Value + 1) * multiplier
				wait()
				end
			
		elseif input.KeyCode == Enum.KeyCode.D then 
			walking = true

			while walking == true do 
				points.Value = (points.Value + 1) * multiplier
				wait()
			end
	elseif input.KeyCode == Enum.KeyCode.A then 
		walking = true

		while walking == true do 
				points.Value = (points.Value + 1) * multiplier
			wait()
		end
		

	end
	end
end)

uis.InputEnded:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.Keyboard then 
		if input.KeyCode == Enum.KeyCode.W then 
			walking = false
		elseif input.KeyCode == Enum.KeyCode.S then 
			walking = false
		elseif input.KeyCode == Enum.KeyCode.D then 
			walking = false

	elseif input.KeyCode == Enum.KeyCode.A then 
		walking = false

	end
	end
end)

You can use the state of the humanoid. It would look like:
While Humanoid.Walking = true do Value = Value + 1 -- change to the amount you want to give per second Wait(1)

this script will work but i think there are better ways to do it

local RunService = game:GetService("RunService")

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid :Humanoid = Character:WaitForChild("Humanoid")

local value = 0 -- the value you want to increase


RunService.Heartbeat:Connect(function()
	if Humanoid.MoveDirection.Magnitude > 0 then -- checks for the player` moving direction
		value += 1 
		print(value)
	end
end)

it checks if the player is moving and if he is moving it will increment the value it will work on any device whenever the character is moved
it is based of the player fps so a player with 120 fps will get 2x the stats from a player with 60fps if you donot want that you can use delta or add it in a while true do loop

if you want to use deltaTime you can replace

value += 1

with

value += delta * 60

whats a delta in a script? sorry if i sound dumb

[GE_0E]

its the time passed since the last frame
you can check it on yt for better explanation
