Loads an Animation onto an Animator, returning an AnimationTrack. Used to load animations on locally controlled models (such as player characters) from the server.

A Model is considered locally controlled if it has network ownership of the model, clients have network ownership of the local character model by default and other models can be assigned to a different client using BasePart/SetNetworkOwner.

It is best practice to only animate a model from the server if the server has network ownership, and for this reason most developers will not need to use the Animator/LoadAnimation function as they can load animations directly from the Humanoid or AnimationController.

Note if the server has network ownership of the model, and the AnimationController or Humanoid was created on the server, then Animator/LoadAnimation does not need to be used as LoadAnimation can be used directly from the Humanoid or AnimationController on the server.

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 Player/Character|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”).
