Gameplay Sequence Demo

The Gameplay Sequence Demo sample demonstrates how to use Unity's Timeline to create a complex cut-scene.

To import the Gameplay Sequence Demo scene and open its Timeline instance, do the following:

Import the Gameplay Sequence Demo sample into your project.
In the Project window, go to Assets/Samples/Timeline/<version>/Gameplay Sequence Demo/Scenes, where <version> is your installed Timeline package version.
Double-click the scene named GameplaySequence.
To open the Timeline instance, in the Hierarchy window, select the Timeline GameObject. The Timeline instance named GameplaySequence displays in the Timeline window.

GameplaySequence Timeline instance

GameplaySequence Timeline instance associated with the Timeline GameObject

The GameplaySequence Timeline instance uses the Markers track and multiple Activation, Animation, Audio, and Control tracks organized into the following Track groups:

Building Track group: Contains tracks for spawning the buildings and controlling particle effects related to the spawned buildings.
Lights Track group: Contains tracks that animate two of the lights in the cut-scene: Sun Light and the Point Light.
Cameras Track group: Contains tracks that creates camera movement and camera switch between two camera GameObjects: Main Camera and Follow Camera.
Characters Track group: Contains tracks that animate the activate the main Player character and the secondary Character2 character.
Audio Track group: Contains multiple audio tracks that play sounds associated with characters, environment, and other effects.
Props Track group: Contains multiple tracks that animate and activate the Table and Can GameObjects. The Props Track group uses the Can Sub-Timeline instance to animate the Can GameObject bouncing and falling off the table.

Markers track

In the GameplaySequence Timeline instance, the Markers track includes a single runtime Signal Emitter at frame 1200. This Signal Emitter emits a signal to play an audio clip at the end of the cut-scene.

The Signal Receiver is attached to the Timeline GameObject. It receives the signal and plays an audio clip of the Player character jogging. This Signal Receiver only receives the signal at runtime and will not play the audio clip while previewing the GameplaySequence Timeline instance in the Timeline window.

The purpose of playing this audio clip is to provide an audio transition from the cut-scene to gameplay when the cut-scene has ended.

Building Track group

The Building Track group expanded

The Building Track group contains the following tracks:

Track	Description
`Building Spawn` Control track	This track contains a Control clip that spawns the building prefab.
`Building Particles` Control track	This track uses two Control clips to add background effects. The `ElectricalSparks` clip provides electrical sparks inside the building. The `SandSwirlsEffect` clip provides the swirling sand effect outside the building.

Lights Track group

The Lights Track group expanded

The Lights Track group contains the following tracks:

Track	Description
`Sun Light` Animation track	This track animates the passage of time from night, to sunrise, and then to day. This effect is achieved by animating the rotation of the light GameObject bound to the `Sun Light` track.
`Point light` Animation track	This track animates a flickering light within the `Building` model. The flickering light effect is achieved by animating the Intensity property of the light GameObject bound to the `Point Light` track.

The animation for each light track is created with keyframe animation on infinite clips. To view the keyframe animation, for either track, do one of the following:

Enable the Curves View toggle in the Track Header. The keyframe animation displays in the Curves View.
Double-click the infinite clip. The keyframe animation displays in the Animation window.

Cameras Track group

The Cameras Track group expanded

The Cameras Track group contains the following tracks:

Track	Description
`Main Camera` Animation track	This track animates the camera movement of the `Main Camera` camera GameObject. The camera movement is created with keyframe animation on an infinite clip. To view this keyframe animation, either enable the Curves View toggle in the Track Header or double-click the infinite clip to open the Animation window.
`Player Shots` Animation Override track	This track is a child of the `Main Camera` Animation track. The clips on this track override the position and rotation of the `Main Camera` camera which provides a camera shot of the main `Player` character.
`Character2 Shots` Animation Override track	This track is a child of the `Main Camera` Animation track. The clips on this track override the position and rotation of the `Main Camera` camera.
`Follow Camera` Activation track	This track activates the `Follow Camera` GameObject. When active, the view from the Follow Camera camera overrides the Main Camera track and its Animation Override tracks. To create this follow camera and camera shot, in the scene, the `Follow Camera` is parented by the `Player` Character so that the `Follow Camera` camera moves with the `Player` Character. A local position and rotation offset is added to the `Follow Camera` GameObject so that the camera shot is from over the left shoulder of the `Player` Character.

Characters Track group

The Characters Track group expanded

The Characters Track group contains the following tracks:

Track	Description
`Player` Animation track	This track animates the `Player` character. This is the main character in the cut-scene. The Animation clip on this track takes control of the `Player` character, collides `Player` with the `Character2` character, bumps `Player` into a table which causes a can to fall and bounce on the floor, then returns control of the `Player` character to the `jog` Animator state. If you attempt to preview this animation in the Timeline window, the `Player` character is shown in a T-Stance pose before and after the Animation clip because the `jog` Animator state is only available during runtime. To preview the `Player` character with the looping jog animation, click Play in the Game View.
`Character2` Activation track	This track activates the `Character2` character. The `Character2` character is the secondary character in the cut-scene.
`Character2` Animation track	This track contains many Animation clips that blend together to create the parkour animation sequence for the `Character2` character. This track also includes animation clips for the collision between characters and `Character2` gesturing towards the main `Player` character.

Audio Track group

The Audio Track group expanded

The Audio Track group contains the following tracks:

Track	Description
`Player` Audio track	This track plays the `jog` Audio clip which contains the jogging and breathing sounds associated with the main Gameplay character. This Audio track also plays the `bump` Audio clip when the two characters collide.
`Sun Light` Audio track	This track plays the `crickets` Audio clip during the night portion of the Gameplay sequence. The `Sun Light` Audio track also has pan and volume track animation. To view this track animation, enable the Curves View toggle for the `Sun Light` Audio Track Header.
`Point Light` Audio track	This track plays the `neon_light` Audio clips as `Character2` moves, jumps, and runs through the Building model. The `neon-light` Audio clip is for the flickering `Point light` effect.
`Character2` Audio track	This track contains the jump and breath audio clips as the `Character2` character parkours through the Building model. The `Character2` Audio track also plays a `bump` Audio clip when the two characters collide.

Props Track group

The Props Track group expanded

The Props Track group contains the following tracks:

Track	Description
`Table` Activation track	This track activates the `Table` GameObject.
`StaticCan` Activation track	This track activates a static copy of the `Can` GameObject. The `StaticCan` GameObject is hidden when the table is bumped and the `Can` Sub-Timeline animation begins.
`TableBase` Animation track	This track contains an Infinite clip that animates the table bump. The table bump also animates the `StaticCan` GameObject because the `StaticCan` is parented to the `TableBase`. This movement causes the can to fall off the table.
`Can Sub-Timeline` Control track	This track includes a Control clip that contains the `Can` Sub-Timeline instance. The `Can` Sub-Timeline contains an Animation track for the can rolling off the table and bouncing on the ground, an Audio track for the sound effects of the bouncing can, and a Control track for the liquid particles splashing out of the can as it bounces. To view the `Can` Sub-Timeline and its additional three tracks, double-click the Control clip.
