how to make it not stop then go. and not like do this odd thing where it like goes after player ONLY if they move:

-- Variables --

local waypointFolder = Instance.new("Folder")
waypointFolder.Name = "Waypoints"
waypointFolder.Parent = script.Parent

local Pathfinding = game:GetService("PathfindingService")
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local ConfigModule = require(game.ServerStorage.ConfigModule)

local path = Pathfinding:CreatePath({
	AgentHeight = 6;
	AgentRadius = 3;
	AgentCanJump = false;

	Costs = {
		Water = 100;
		DangerZone = math.huge
	}
})

local Character = script.Parent
local humanoid = Character:WaitForChild("Humanoid")
local humanoidRootPart = Character:WaitForChild("HumanoidRootPart")
local aiPaths = script.Parent.Parent:FindFirstChild("AiPaths")

local waypoints
local nextWaypointIndex

			local targetRoot = target.HumanoidRootPart
			local distance = (humanoidRootPart.Position - targetRoot.Position).Magnitude

			if distance < maxDistance then
				nearestTarget = target
				maxDistance = distance
			end

			-- **Kill instantly if too close**
			if distance < 3 then
				target.Humanoid.Health = 0
				return nil -- Stop chasing if the player is dead
			end
		end
	end

	return nearestTarget
end

local function followPath(destination, onComplete)
	local success, errorMessage = pcall(function()
		path:ComputeAsync(humanoidRootPart.Position, destination)
	end)

	if success and path.Status == Enum.PathStatus.Success then
		waypoints = path:GetWaypoints()
		nextWaypointIndex = 2

		if blockedConnection then blockedConnection:Disconnect() end
		if reachedConnection then reachedConnection:Disconnect() end

		if ConfigModule.BotDebuger then
			waypointFolder:ClearAllChildren()

			local previousPart

			end
		end)

		humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
	else

end

local function roam()
	if aiPaths and not isChasing and not isRoaming then
		local points = aiPaths:GetChildren()

end

while wait(0.2) do -- **Faster updates**
	local target = findTarget()

		isChasing = true

Trying using RunService.Heartbeat instead of a while loop.

local RunService = game:GetService("RunService")

RunService.Heartbeat:Connect(function(dt: number)
	local target = findTarget()

	if target then
		isChasing = true
		isRoaming = false -- **Stop roaming instantly**
		currentRoamPoint = nil -- **Clear roam target**
		local targetRoot = target.HumanoidRootPart

		-- **Update path only if the target moves more than 3 studs**
		if not lastTargetPosition or (targetRoot.Position - lastTargetPosition).Magnitude > 3 then
			lastTargetPosition = targetRoot.Position
			followPath(targetRoot.Position)
		end
	else
		isChasing = false
		if not isRoaming and not currentRoamPoint then
			roam()
		end
	end
end)

or RunService:BindToRenderStep() if you want to instantly stop checking by using RunService:UnbindFromRenderStep()

Can you show a video of what you mean?

#4

Using RunService is a good option but it’s worth noting that if OP decides to use a lot of NPCs then it can cause a lot of latency issues.

#5

Set the npc rootpart’s network owner to Server by
humanoidRootPart:SetNetworkOwner(nil)
You can learn about network ownership here …
