Path finding AI

Help and Feedback Scripting Support
#1

  1. okay so i want to make an NPC that is able to follow the nearest players while also avoiding walking into walls and being able to jump over anything that might block its path (like parts or what not)

  2. i have a script that does exactly that BUT it is very slow, i made it in a way it creates waypoints to the players location and then it moves to that waypoint and creates a new one, etc etc etc. problem is, the player is always moving and it makes the NPC just look kinda dumb moving to the last “known/created” waypoint

  3. i’m not amazing or great or generally good with making such scripts. i have used the ai assistance and looking up a few things, a friend of mine said i’d be good to use raycasting but idk anything about that

below here is the script that i use for the NPC to create waypoints and basically just "follow’ the player.
Currently i have the human.MoveToFinished:Wait() because i was kinda getting lost and figured why not disable it for the NPC to get to the finish and just go straight for the player, but that just made it like any other simple follow script.

some variables

local human = script.Parent:WaitForChild(“Humanoid”)
local torso = script.Parent:WaitForChild(“Torso”)


local function FollowNearestPlayer()

	local nearestPlayer = getNearestPlayer()
	if nearestPlayer and nearestPlayer.Character and nearestPlayer.Character:FindFirstChild("HumanoidRootPart") then
		human.WalkSpeed = normalWalkSpeed
		local targetPosition = nearestPlayer.Character.HumanoidRootPart.Position
		local path = PathfindingService:CreatePath()
		path:ComputeAsync(torso.Position, targetPosition)
		local waypoints = path:GetWaypoints()
		
		path.Blocked:Connect(function()
			print("sum is blocking its path")
		end)
		
		
		for i, waypoint in waypoints do
			if waypoint.Action == Enum.PathWaypointAction.Jump then
				human:ChangeState(Enum.HumanoidStateType.Jumping)
				wait(1)
			end
			human:MoveTo(waypoint.Position)
		--	human.MoveToFinished:Wait()
			end
	else
		human.WalkSpeed = 0
		if human.WalkSpeed > 0 then
			error("NPC didnt change speed")
		end
		end
end

Do you want to just use this?
NoobPath

local NoobPath = require(PathToNoobPath)
local Path = NoobPath.Humanoid(human.Parent)
Path.Speed = normalWalkSpeed
Path.Timeout = true

local function FollowNearestPlayer()

    local nearestPlayer = getNearestPlayer()
	if nearestPlayer and nearestPlayer.Character and nearestPlayer.Character:FindFirstChild("HumanoidRootPart") then
		human.WalkSpeed = normalWalkSpeed
        local targetPosition = nearestPlayer.Character.HumanoidRootPart.Position
       
        Path.Trapped:Connect(function()
			print("sum is blocking its path")
		end)

        Path:Run(targetPosition)
    else
        human.WalkSpeed = 0
		if human.WalkSpeed > 0 then
			error("NPC didnt change speed")
		end
    end

end
