[Modestkid2022 (Max)]

im trying to make a ai that can roam. but just dont know how to. with out breaking the go after player
so bascily if the player is near and not behind a wall. it goes after player. other then that it does a roam.

but i tried to before and it jusr broke. so i made a go after player only script. plz help:

-- Variables --

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

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 waypoints
local nextWaypointIndex
local reachedConnection
local blockedConnection

local function findTarget ()
	local maxDistance = 500
	local nearestTarget

	for index, player in pairs(Players:GetPlayers()) do
		if player.Character then
			local target = player.Character
			local distance = (Character.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude

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

			if distance < 5 then
				nearestTarget.Humanoid:TakeDamage(25)
			end
		end
	end

	return nearestTarget
end

local function followPath(destination)

	local success, errorMessage = pcall (function()
		path:ComputeAsync(Character.PrimaryPart.Position, destination)
	end)

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

		blockedConnection = path.Blocked:Connect (function(blockedWayPointIndex)
			if blockedWayPointIndex >= nextWaypointIndex then
				blockedConnection:Disconnect()
				followPath(destination)
			end
		end)

		if not reachedConnection then
			reachedConnection = humanoid.MoveToFinished:Connect(function(reached)
				if reached and nextWaypointIndex < #waypoints then
					nextWaypointIndex += 1
					humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
				else
					reachedConnection:Disconnect()
					blockedConnection:Disconnect()
				end
			end)
		end

		nextWaypointIndex = 2
		humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
	else
		warn("Path not computed!", errorMessage)
	end
end

while wait() do
	local target = findTarget()
	if target then
		print(target.Name)
		followPath(target.HumanoidRootPart.Position)
	end
end

roam points: script.Parent.Parent.AiPaths:GetChildren()

A popular thing to do with NPC ai like this is to make several different states that the script can change to. Depending on the state, your pathfinding should have some different calculations.

There’s a lot of underlying details to make AI good at looking natural, but the simplest thing would have different parts of code activate for different events.

If you want some inspiration, SS13 has a lot of good open-source code with their mob AI. Its coding language (BYOND/Dream Maker) is a bit hard to read though sometimes
