Introduction to Timeline in Unity
The Unity Timeline is a feature that allows you to visually edit music, play animations, show/hide objects, control particles, etc. along the time axis. It is similar to adding and editing music, video, subtitles, and direction to a track in video editing software.
To use this tool you must add it to the project through the Package Manager.
After adding it we can open its Tab and begin to understand the magic that is hidden inside.
We can define a timeline for our Game Objects to turn them on and off at will, interpolate the transition from one camera to another, or build animations for the game cameras to manage camera movements.
