Unity Game Optimization - Third Edition

Attributes

Attributes are very useful meta-level tags that can be given to almost any target in C#. They are commonly used on fields and classes, allowing us to flag them with special properties so that they can be processed differently. Intermediate and advanced Unity developers will find it worthwhile to read the C# documentation on attributes and use their imagination to come up with their own attributes that help accelerate their workflow. There are quite a few attributes built into the Unity engine that can be exceptionally useful when used in the right place.

Advanced users will note that attributes can also be given to enums, delegates, methods, parameters, events, modules, and even assemblies.
