Whats the best way to make a npc follower?

Im trying to make an npc that will just walk behind the player and follow them around. I tried using pathfinding to do this but it seems to be really janky and chopy. Heres the code for it :

01--Services
02local PathFindingService = game:GetService("PathfindingService")
03 
04--Variables
05local targetCharacter = script.Parent.Parent.Parent
06local target = targetCharacter:WaitForChild("HumanoidRootPart")
07local localCharacter = script.Parent.Parent
08local localHumanoid = localCharacter:WaitForChild("Humanoid")
09local localRoot = localCharacter:WaitForChild("HumanoidRootPart")
10 
11--Functions
12function moveTo()
13    print("Moving to player")
14    local pos = target.Position + target.CFrame.LookVector * -2 + target.CFrame.RightVector * 2
15    localHumanoid:MoveTo(pos)
16end
17 
18function drawWaypoint(point)
19    local part = Instance.new("Part", workspace)
20    part.BrickColor = BrickColor.new("White")
21    part.Shape = "Ball"
22    part.Material = "Neon"
23    part.Transparency = 0.25
24    part.Anchored = true
25    part.Locked = true
26    part.CanCollide = false
27    part.Size = Vector3.new(1,1,1)
28    part.Position = point.Position
29    game:GetService("Debris"):AddItem(part,1)
30end
31 
32function generatePath()
33    print("Generating Path")
34    local path = PathFindingService:CreatePath()
35    path:ComputeAsync(localRoot.Position ,target.Position + target.CFrame.LookVector * -2 + target.CFrame.RightVector * 2)
36    return path
37end
38 
39function moveAlongWaypoints(path)
40    print("Moving along waypoints")
41    local wayPoints = path:GetWaypoints()
42    for _,waypoint in pairs(wayPoints)do
43        print("Next waypoint")
44        drawWaypoint(waypoint)
45        localHumanoid:MoveTo(waypoint.Position)
46        localHumanoid.MoveToFinished:Wait()
47    end
48end
49 
50function main()
51    local path = generatePath()
52    if path ~= nil and path.Status == Enum.PathStatus.Success then
53        print("Path was Successfully made")
54        moveAlongWaypoints(path)
55    else
56        warn("Failed to generate path") 
57    end
58end

60--Loops main function
61while true do  
62    print("Running Main")
63    main()
64    game:GetService("RunService").Stepped:Wait()
65end

If some one could fix the code to make the movement smoother or just tell me a better way I would apreaciate it alot :)

Instead of doing while true do, use RenderStepped, because that will run everytime a new frame is generated. I think this would make the movements and turning smoother? But, I'm not sure. I don't really work with AI or PathFindingService. Fires every frame prior to the frame being rendered. https://developer.roblox.com/en-us/api-reference/event/RunService/RenderStepped killerbrenden 1537 — 5y
