Creating a Timeline Asset and Timeline instance

To use a TimelineGeneric term within Unity that refers to all features, windows, editors, and components related to creating, modifying, or reusing cut-scenes, cinematics, and game-play sequences. More info

Asset in your SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

, associate the Timeline Asset with a GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info

using a Playable Director component. Associating a Timeline AssetRefers to the tracks, clips, and recorded animation that comprise a cinematic, cut-scene, game-play sequence, or other effect created with the Timeline Editor window. A Timeline Asset does not include bindings to the GameObjects animated by the Timeline Asset. The bindings to scene GameObjects are stored in the Timeline instance. The Timeline Asset is Project-based. More info

with a Playable Director component creates a Timeline instanceRefers to the link between a Timeline Asset and the GameObjects that the Timeline Asset animates in the scene. You create a Timeline instance by associating a Timeline Asset to a GameObject through a Playable Director component. The Timeline instance is scene-based. More info

and allows you to specify which objects in the Scene are animated by the Timeline Asset. To animate a GameObject, it must also have an Animator component.

The Timeline window automatically creates a Timeline instance while creating a new Timeline Asset. The Timeline window also creates the necessary components.

To create a new Timeline Asset and Timeline instance, follow these steps:

  1. In your Scene, select the GameObject that you want to use as the focus of your cinematic or other gameplay-based sequence.

  2. Open the Timeline window (menu: Window > Sequencing > Timeline). If the GameObject does not yet have a Playable Director component attached to a Timeline Asset, a message in the Timeline window prompts you to click the Create button.

  3. Click Create. A dialog box prompts you for the name and location of the Timeline Asset you are creating. You can also specify tags to identify the Timeline Asset.

  4. Click Save.

The Timeline window does the following:

  • Saves a new Timeline Asset to the Assets directory of your Project. If you did not change the name and location of the Timeline Asset you are creating, the Timeline window creates a name based on the selected GameObject with the “Timeline” suffix. For example, selecting the GameObject called “Enemy” names the Asset “EnemyTimeline”.

  • Adds an empty Animation track to the Timeline Asset.

  • Adds a Playable Director component to the selected GameObject, and sets the Playable property to the Timeline Asset. This creates a Timeline instance.

  • Sets the binding on the Animation track in the Playable Director component to the selected GameObject. The Animation track does not have any clips, so the selected GameObject is not animated.

  • Adds an Animator componentA component on a model that animates that model using the Animation system. The component has a reference to an Animator Controller asset that controls the animation. More info

    to the selected GameObject. The Animator component animates the GameObject through the Timeline instance. The GameObject cannot be animated without an Animator component.
