Working With Prefabs
Overview
Prefabs are groups of objects which can be placed in your level as instances. An instance is an object which is an exact copy of every other object of the same type. When you edit one instance of an object, every other instance that exists in your game will change, either instantly or when the instance is reloaded.
Index
What are prefabs?
A prefab is a predefined group of objects. Every time you place down a prefab, each instance is precisely the same in every way. Altering a prefab will make it change everywhere it has been placed. Any alterations need to be saved to the prefab library to ensure they are correctly propagated across your entire game.
