Unity c# default script structure

Unity's default script structure is as follows:

  1. Namespace references (groups of classes that can be used in the script).
  2. Class name that inherits from MonoBehaviour (Unity's base class).
  3. Start() is a built-in function that is called at the start of the script initialization.
  4. Update() is a built-in function that is called every frame and is used for implementing continuous logic such as key-press, player movement, etc.
