#1

  1. What do you want to achieve? I wanna play the anim attack left and right if it is close to player and damage them

  2. What is the issue? i get a error saying AnimationTrack limit of 256 tracks for one Animator exceeded, new animations will not be played. (x408) - Studio causing MASSIVE LAG

  3. What solutions have you tried so far? i looked on dev forum but i didnt understand and dont know if they could help with my issue

here’s the script (idk how to fix it because im still learning)

local Rig = script.Parent
local Humanoid = Rig:WaitForChild("Humanoid")
local RootPart = Rig:WaitForChild("HumanoidRootPart")
local ScreamSound = Rig:WaitForChild("ScreamSound")
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local DetectionRange = 60
local AttackRange = 5

local IsScreaming = false
local IsChasing = false

local ScreamSpeed = 0
local ChaseSpeed = 25

local IsWandering

local WanderDelay = Rig.Config.WanderDelay.Value

local AttackAnimations = {
	Left = {
		Animation = Rig:WaitForChild("AttackAnimationLeft"),
		Damage = 5,
	},
	Right = {
		Animation = Rig:WaitForChild("AttackAnimationRight"),
		Damage = 7,
	}
}

local Animator = Humanoid:FindFirstChildOfClass("Animator") or Instance.new("Animator", Humanoid)

local function getNearestLowestHealthPlayer()
	local nearestPlayer = nil
	local lowestHealth = math.huge

	for _, player in pairs(Players:GetPlayers()) do

			local character = player.Character
			local playerHumanoid = character:FindFirstChild("Humanoid")
			local distance = (RootPart.Position - character.HumanoidRootPart.Position).magnitude

			if distance < DetectionRange and playerHumanoid.Health < lowestHealth then
				nearestPlayer = player
				lowestHealth = playerHumanoid.Health
				closestDistance = distance
			end
		end
	end

	return nearestPlayer, closestDistance
end

local function wander()
	local randomDirection = Vector3.new(math.random(-1, 1), 0, math.random(-1, 1)).unit

	Humanoid:MoveTo(destination)
	Humanoid.WalkSpeed = WanderSpeed
end

local function avoidObstacles()

	local hit = workspace:FindPartOnRay(ray, Rig)

	if hit then

	end
end

			Humanoid:MoveTo(playerCharacter.HumanoidRootPart.Position)
			wait(0.1)
		end

		IsChasing = false
		Humanoid.WalkSpeed = WanderSpeed
	end
end

local function attackPlayer(player)
	if (RootPart.Position - player.Character.HumanoidRootPart.Position).magnitude < AttackRange then
		local randomAttack = math.random(2) == 1 and "Left" or "Right"
		local attackAnimInfo = AttackAnimations[randomAttack]
		local attackAnim = Animator:LoadAnimation(attackAnimInfo.Animation)

		attackAnim:Play()

		local connection
		connection = attackAnim:GetMarkerReachedSignal("DamagePoint"):Connect(function()
			if (RootPart.Position - player.Character.HumanoidRootPart.Position).magnitude < AttackRange then

			wander()
			delay(WanderDelay, function()
				IsWandering = false
			end)
		end
	end

	local nearestPlayer, distance = getNearestLowestHealthPlayer()
	if nearestPlayer and distance < DetectionRange then
		screamAndChase(nearestPlayer)
	end

	if nearestPlayer and distance < AttackRange then
		attackPlayer(nearestPlayer)
	end
end)

The problem is caused by you loading the animation every time the attack happens. You should load the animation only once when necessary.

The other option is to use a Module which loads all animations on to the characters which is then called to Play the animations when required. There is an example one somewhere on the DevForum I have seen:

so basically, just load the animations and put them in a table, then play the stored animation, or use the module
