In-Depth Information
The game controller for this game is created dynamically by the LevelSetup script
component attached to the empty gameObject named LevelSetup. The actual script will
be broken down later in this chapter, but the basic function of the script is to check to see
whether a game controller exists in the scene and, if not, to instantiate one. It references
two prefabs, one called GameController and one SceneManager.
By creating the game controller and scene manager objects dynamically, these objects
can exist across different game levels. The level setup script first checks to see whether
they exist, and if the game scene is a level other than the first one, the objects will not be
duplicated accidentally.
When the game controller prefab is instantiated, its gameObject looks like this, in the
Hierarchy window of the Unity editor:

It can be seen that the GameController prefab contains everything required for the
game controller to function, create a player, and have a camera and UI available to use
during the game. The prefab contains the minimum amount required to run the game, the
most important elements. With the exception of the LevelSetup gameObject in each game
scene, everything else in the level scenes is specific to the level.
