Learn that a Prefab is a reusable GameObject template.
What Is a Prefab?
A Prefab is a reusable template of a GameObject, stored together with its components and settings. Once you save an object as a Prefab, you can reuse the same structure in different scenes. For example, you can create a Prefab for an enemy, a chest, or a decorative object.
// Enemy Prefab
// Chest Prefab
// Decoration PrefabManaging Changes with Prefabs
Scene instances connected to a Prefab asset can be affected by changes made to the source. For example, when you edit a shared component in the Prefab, the change can be applied to connected instances. This allows you to manage similar objects from a single source.
// Shared Prefab
// Multiple Instances
// Centralized ChangesPractice Define a Prefab Reference
Declare a public variable in a Unity C# script that can hold a GameObject Prefab asset. A Prefab can then be assigned to this variable through the Inspector.
