May I ask how could I make NPCs walk by themselves? I have seen Roblox Forums but it does not help.

Also, could you mark this as an answer please? I spent ages on it :D Agent_EpicNoob 71 — 4y

Thank you for spending so much time. I really appreciate it! SUPERMEGADANTHEMAN 33 — 4y

[Before you start reading, Here's the model if you're too confused: https://web.roblox.com/library/5001846573/Walking-NPC Also, I took ages on this, please mark it as an asnwer PLZ!]

Step 1: Make a group named something like "Walking NPC"

Step 2: Insert 5 parts inside it, or as many points you would like the NPC to walk to. Then, insert a dummy into the model. Put whatever you like on it to make it look cool.

Step 3: Name the parts you inserted in, to: PointA, PointB, PointC, ect.

Step 4: Insert 2 scripts into the dummy, and name them "Animate" and "Walk"

Step 5: Insert this into the animate script:

001function waitForChild(parent, childName)
002    while true do
003        local child = parent:findFirstChild(childName)
004        if child then
005            return child
006        end
007        parent.ChildAdded:wait()

Step 6: Insert this into the walk script:

01model = script.Parent.Parent
02hum = script.Parent.Humanoid
03torso = script.Parent.Torso
04while true do
05    if model.PointA ~= nil then
06        a = model.PointA
07        hum:MoveTo(a.Position, a)
08        repeat
09            wait(0.1)
10        until (a.Position - torso.Position).magnitude <= 5
11    else
12        print("No Point A.")
13    end
14wait(0.1)
15    if model.PointB ~= nil then
16        b = model.PointB
17        hum:MoveTo(b.Position, b)
18        repeat
19            wait(0.1)
20        until (b.Position - torso.Position).magnitude <= 5
21    else
22        print("No Point B.")
23    end
24wait(0.1)
25    if model.PointC ~= nil then
26        c = model.PointC
27        hum:MoveTo(c.Position, c)
28        repeat
