Monster Stutters When Chasing Player

Help and Feedback Scripting Support

Hello! I Am Making A Horror Game Monster And There Is A Glitch(?) That Is A Bit Annoying Where The Monster Just Starts Stuttering And Not Chasing Smoothly, I Cant Really Explain More So I’ll Just Send A Video.

Video Of The Glitch :

AI Script :

local VDI = script.Parent
local Humanoid = VDI.Humanoid
local PathFindingService = game:GetService("PathfindingService")
VDI.PrimaryPart:SetNetworkOwner(nil)

local timeout = 0
local maxTimeout = 100 --How many times it checks before deciding to proceed anyways
local nextPointDistance = 2 --How far VDI has to be before going to next point

local function CanSeeTarget(Target)
	local origin = VDI.HumanoidRootPart.Position
	local direction = (Target.HumanoidRootPart.Position - VDI.HumanoidRootPart.Position).unit * 40
	local ray = Ray.new(origin, direction)
	
	local hit, pos = workspace:FindPartOnRay(ray, VDI)
	
	if hit then
		if hit:IsDescendantOf(Target) then
			return true
		end
	else
		return false
	end
end

local function FindTarget()
	local Players = game.Players:GetPlayers()
	local MaxDistance = 75
	local NearestTarget = nil

	for index, player in pairs(Players) do
		if player.Character then
			local Target = player.Character
			local Distance = (VDI.HumanoidRootPart.Position - Target.HumanoidRootPart.Position).Magnitude

			if Distance < MaxDistance and CanSeeTarget(Target) then
				NearestTarget = Target
				MaxDistance = Distance
			end
		end
	end

	return NearestTarget
end

local function GetPath(destination)
	local PathParms = {
		["AgentHeight"] = 8,
		["AgentRadius"] = 6,
		["AgentCanJump"] = false
	}

	local Path = PathFindingService:CreatePath(PathParms)

	Path:ComputeAsync(VDI.HumanoidRootPart.Position, destination.Position)

	return Path
end

local function Attack(Target)
	local Distance = (VDI.HumanoidRootPart.Position - Target.HumanoidRootPart.Position).Magnitude

	if Distance > 8 then
		Humanoid:MoveTo(Target.HumanoidRootPart.Position)
		Humanoid.WalkSpeed = 32
	else
		Target.Humanoid.Health = 0
	end
end

local function WalkTo(destination)
	local Path = GetPath(destination)

	if Path.Status == Enum.PathStatus.Success then
		for index, waypoint in pairs(Path:GetWaypoints()) do
			local Target = FindTarget()

			if Target and Target.Humanoid.Health > 0 then
				Attack(Target)
				break
			else
				Humanoid.WalkSpeed = 16
				Humanoid:MoveTo(waypoint.Position)
				repeat
					task.wait(0.05) --You can change this to whatever to increase or decrease checking speed
					timeout += 1
				until timeout >= maxTimeout or (VDI.PrimaryPart.Position - Vector3.new(0, 5, 0) - waypoint.Position).Magnitude <= nextPointDistance
				timeout = 0
			end
		end
	else
		Humanoid:MoveTo(destination.Position - (VDI.HumanoidRootPart.CFrame.LookVector * 10))
	end
end

local function Patrol()
	local WayPoints = workspace.WayPoints:GetChildren()
	local RandomNum = math.random(1, #WayPoints)

	WalkTo(WayPoints[RandomNum])
end

while task.wait(0.5) do	
	Patrol()
end
#2

If i under it correctly this is the number that messes everything up, try setting it to 1.

#3

the Distance 8 or AgentHeight 8?

#4

The distance 8

Putting this here because i need text: aaaaaaaaaaaaaaaaaaaaaaaaaa

#5

it is still the same. did not change anything.

#6

The reason it is stuttering is because it is not taking the most recent player’s position.

You could fix this in two ways:

  1. Change while task.wait(0.5) do to while task.wait() do
  2. Try and predict where the player is going to move next, but this will be a longer process.
