How would I get my pathfinding AI to follow a player's position?

I've been working on pathfinding ai, and I know how to get an ai to walk around randomly and from one point to another, but I just haven't been able to figure out how to get a player's position so the ai follows them. I haven't been able to get the value out of event functions that get the players position. How would I return the value so I could use it as the end goal of the move function? Here's my code. Any help is appreciated :)

function move()
	local human = script.Parent.Humanoid
	local torso = script.Parent.HumanoidRootPart
	local service = game:GetService("PathfindingService")
	script.Parent.HumanoidRootPart.Anchored = false

	local path = service:CreatePath()
	path:ComputeAsync(torso.Position,game.ReplicatedStorage.Vector3Value.Value) -- DONT KNOW HOW TO GET PLAYER POSITION
	local waypoints = path:GetWaypoints()

-- getting player position	
	game.Players.PlayerAdded:Connect(function(player)
		game.Players.CharacterAdded:Connect(function(character)
			local value = character.HumanoidRootPart.Position
			game.ReplicatedStorage.Vector3Value.Value = Vector3.new(character.HumanoidRootPart.Position) -- DONT KNOW HOW TO GET PLAYERS POSITION OUT OF THIS FUNCTION
		end)
	end)	

	for i, v in pairs(waypoints) do
		human:MoveTo(v.Position)
		human.MoveToFinished:Wait(2)
	end
end

while wait(3) do
	move()
end

local RS = game:GetService("RunService")
local RepS = game:GetService("ReplicatedStorage")
local NPC = workspace.NPC.Humanoid

game.Players.PlayerAdded:Connect(function(plr)
	
	plr.CharacterAdded:Wait()
	
	local HRP = plr.Character.HumanoidRootPart
	
	local lastPos = HRP.Position
		
	RS.Stepped:connect(function()
		if lastPos ~= HRP.Position then
			lastPos = HRP.Position
			NPC:MoveTo(HRP.Position)
		end
		
	end)		
	
end)

I made this hope it helps. If you need any more help please contact me. I'm not sure this is 100% what you're looking for though.
