How can i make an NPC that follows the player when he sees him?

Basically, I want to make an NPC that wanders around until he sees a player, then he follows him until the player is dead, and the NPC stops moving if the player is looking at him, however, I have no idea how to do that, so far, I got this script that I found from a tutorial, it works, however, it goes directly to the player. (It’s located on StarterPlayer.StarterCharacterScripts)

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local PathfindingService = game:GetService("PathfindingService")
local ServerStorage = game:GetService("ServerStorage")

local NPC = ServerStorage.NPC
local NPCHumanoid = NPC.Humanoid
local NPCHumanoidRoot= NPC.HumanoidRootPart
local Player = script.Parent
local PlayerHumanoidRoot = Player.HumanoidRootPart

local TeleportingDebounce = false

NPC.Parent = workspace
NPC.PrimaryPart:SetNetworkOwner(nil)

local function FollowPlayer()
	local Path = PathfindingService:CreatePath()
	local MovingToPosition = PlayerHumanoidRoot.Position - Vector3.new(0, 0, 0)
	local ComputedPath = Path:ComputeAsync(NPCHumanoidRoot.Position, MovingToPosition)
	return Path
end

RunService.Stepped:Connect(function()
	FollowPlayer()
	local Path = FollowPlayer()
	for _, waypoint in pairs(Path:GetWaypoints()) do
		NPCHumanoid:MoveTo(waypoint.Position)
	end
end)

How can I do that?

Loop through all players, find a player’s character which is closest in the 3D environment (worldspace) to the NPC and then move the NPC’s model towards them.

That doesn’t solve the problem, I think I didn’t explain very well, basically, I want the NPC to have a radius and if a player is in that radius, he’s going to get followed by the NPC

#4 
RunService.Stepped:Connect(function()
    if (NPCHumanoidRoot.Position - PlayerHumanoidRoot.Position).Magnitude < 5 then
        print("Player near NPC.")
        FollowPlayer()
	    local Path = FollowPlayer()
	    for _, waypoint in pairs(Path:GetWaypoints()) do
		   NPCHumanoid:MoveTo(waypoint.Position)
	    end
    else
        print("The player is far from the NPC.")
    end
end)

It worked! Thank you so much! Now the next part, how can i make the NPC walk around to random places near him?

#6

Can you explain in more detail? Do you want the NPC to move around randomly all the time?

#7

Yes! That way, he’s not just stopped in one random place waiting for the player to come near.

#8

Do you want it to move to random places when the player is standing or walking? Or both?

#9

Or you could add an invisible uncollidable sphere and detect if player hits it with workspace:GetPartsInPart.

But @FunAsiK’s suggestion should work better

#10

I think both would be the better option.

#11 
local function FollowPlayer()
	local Path = PathfindingService:CreatePath()
	local MovingToPosition = PlayerHumanoidRoot.Position - Vector3.new(math.random(-10,10), 0, math.random(-10,10))
	local ComputedPath = Path:ComputeAsync(NPCHumanoidRoot.Position, MovingToPosition)
	return Path
end

This should work.

You can remove the -10 or 10 and put in your own, just experiment with them until you get what you want.

I don’t want the NPC to go directly to a position near the player, i want it to go somewhere random in the map.

#13

Try to set a larger value like -100, 100.

#14

Oh wait, never mind! If i change PlayerHumanoidRoot to NPCHumanoidRoot and make a separate function for that, the NPC will walk on it’s own. Thanks!

And please stop advertising for others to go to your post. :neutral_face:
