How to make an NPC that walks and looks at the player?

[MIKI_BLOXYCOLA33 (MARFRUNYA)]

You can write your topic however you want, but you need to answer these questions:

1. i want to make AI npc that moving around a player and shoot

2. The humanoid NPC cannot move because the rotation is being done by changing the CFrame.

3. i have no ideas how to fix it
   this is how im rotating my npc

npcRoot.CFrame = CFrame.new(npcRoot.Position, Vector3.new(target.Position.X, npcRoot.Position.Y, target.Position.Z))

npc must look at player only in Y axis, and be able to walk at the same time

why you don’t change motor6D of HumanoidRootPart or Torso ?

it will NPC walk while it’s rotation changed

I’ve acctually done something quite similar for a game before, the script below will follow the closest player until a certain distance away and always face the player. The script should be placed inside a model of an NPC that has a Humanoid and a HumanoidRootPart inside.

local npc = script.Parent
local humanoid = npc:WaitForChild("Humanoid")
local rootPart = npc:WaitForChild("HumanoidRootPart")
local runService = game:GetService("RunService")
local players = game:GetService("Players")

local followDistance = 5 --how close npc should get
local moveSpeed = 8 --walking speed

humanoid.WalkSpeed = moveSpeed

local function getClosestPlayer()
	local closestPlayer, closestDist
	for _, player in pairs(players:GetPlayers()) do
		if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
			local dist = (player.Character.HumanoidRootPart.Position - rootPart.Position).Magnitude
			if not closestDist or dist < closestDist then
				closestDist = dist
				closestPlayer = player
			end
		end
	end
	return closestPlayer
end

runService.Heartbeat:Connect(function()
	local targetPlayer = getClosestPlayer()
	if targetPlayer and targetPlayer.Character and targetPlayer.Character:FindFirstChild("HumanoidRootPart") then
		local targetPos = targetPlayer.Character.HumanoidRootPart.Position
		local dist = (targetPos - rootPart.Position).Magnitude

		--face player
		local lookAtCFrame = CFrame.lookAt(rootPart.Position, Vector3.new(targetPos.X, rootPart.Position.Y, targetPos.Z))
		rootPart.CFrame = lookAtCFrame

		--only walk if too far away
		if dist > followDistance then
			humanoid:MoveTo(targetPos)
		else
			humanoid:MoveTo(rootPart.Position) --stop moving
		end
	end
end)

thank you😇. i was using RunServ.Stepped insted of RunServ.Heartbeat
