Show Deprecated

An object which allows animations to be loaded and applied to a character or model in place of a Humanoid when a Humanoid is not needed. Creates an Animator and loads animations to update Motor6Ds of said character to react in the way that is described within the animation asset referenced by an Animation object.

Should I load an Animation on the client or server?

In order for AnimationTracks to replicate correctly, it's important to know when they should be loaded on the client (via aLocalScript) or on the server (via a Script).

If an Animator is a descendant of a Humanoid or AnimationController in a Player's Character then animations started on that Player's client will be replicated to the server and other clients.

If the Animator is not a descendant of a player character, its animations must be loaded and started on the server to replicate.

The Animator object must be initially created on the server and replicated to clients for animation replication to work at all. If an Animator is created locally, then AnimationTracks loaded with that Animator will not replicate.

Both Humanoid:LoadAnimation() and AnimationController:LoadAnimation() will create an Animator if one does not already exist. When calling LoadAnimation from LocalScripts you need to be careful to wait for the Animator to replicate from the server before calling LoadAnimation if you want character animations to replicate. You can do this with WaitForChild("Animator").

Code Samples

Using an AnimationController to animation non-player objects

local InsertService = game:GetService("InsertService")
-- Load a model for demonstration
local npcModel = InsertService:LoadAsset(516159357):GetChildren()[1]
npcModel.Name = "NPC"
npcModel.PrimaryPart.Anchored = true
npcModel:SetPrimaryPartCFrame(, 5, 0))
npcModel.Parent = workspace
-- Replace the humanoid with an animationcontroller
local humanoid = npcModel:FindFirstChildOfClass("Humanoid")
local animationController ="AnimationController")
animationController.Parent = npcModel
-- Create and load an animation
local animation ="Animation")
animation.AnimationId = "" -- Roblox dance emote
local animationTrack = animationController:LoadAnimation(animation)
-- Play the animation
