How to make a npc follow you?

Help and Feedback Scripting Support
#1

Hi so i tried making a npc follow you and i tested it out but the only problem is that at the start the part follows (also i was testing the system thats why i am using a part) and when you go backwards the part is infront of you instead of behind you?

heres a script:

local click = script.Parent.ClickDetector

click.MouseClick:Connect(function(player)
	if player then
		local Character = player.Character
		
		local HRP = Character.HumanoidRootPart
		
		while true do
			wait(0.01)
			script.Parent.CFrame = HRP.CFrame + Vector3.new(4,0,4)

		end
	end
end)

Try this script with a rig :

local npc = script.Parent
local humanoid = npc:FindFirstChild("Humanoid")
local rootPart = npc:FindFirstChild("HumanoidRootPart")

local walkAnimationId = "rbxassetid://913402848" -- walk ID
local walkAnimation = Instance.new("Animation")
walkAnimation.AnimationId = walkAnimationId
local walkAnimTrack = humanoid:LoadAnimation(walkAnimation)

-- distance from the player
local distanceToFollow = 15
local distanceToStop = 5

local function getClosestPlayer()
	local closestPlayer = nil
	local shortestDistance = distanceToFollow

	for _, player in pairs(game.Players:GetPlayers()) do
		local character = player.Character
		if character and character:FindFirstChild("HumanoidRootPart") then
			local playerRootPart = character.HumanoidRootPart
			local distance = (rootPart.Position - playerRootPart.Position).Magnitude
			if distance < shortestDistance then
				closestPlayer = player
				shortestDistance = distance
			end
		end
	end
	return closestPlayer
end

local function followPlayer()
	local player = getClosestPlayer()

	if player then
		local targetPosition = player.Character.HumanoidRootPart.Position
		local distance = (rootPart.Position - targetPosition).Magnitude

		if distance > distanceToStop then
			humanoid:MoveTo(targetPosition)
			if not walkAnimTrack.IsPlaying then
				walkAnimTrack:Play()  
			end
		else
			humanoid:MoveTo(rootPart.Position) 
			walkAnimTrack:Stop() 
		end
	else
		humanoid:MoveTo(rootPart.Position) 
		walkAnimTrack:Stop() 
	end
end

while wait(0.5) do
	followPlayer()
end

Put this in a basic script in a rig model.
