Scene

Scene

The scene class contains all the objects in the game world. Its main job is to propagate the OnStart, OnUpdate, OnRender calls down the scene hierarchy, so that each component receives a chance to call its game logic. For more information on how the bigger picture works, have a look at the Engine Loop.

The Scene is destroyed by the ToyRendererApp class, either during its destruction or whenever it is necessarily. The Scene itself has ownership over the GameObject it holds, and deletes them once it is destroyed. Gameobejcts are unique and shouldn't be shared across Scenes.

Its main functions are:

Function name	Purpose
OnStart()	For initialization of game logic and values after the scene construction
OnUpdate()	For running the main CPU orientated Game logic
OnRender()	Used for rendering calls to the RHI after the game logic
OnGui()	Used for GUI rendering as well as GUI logic

Its main member values are:

Member	Purpose
Renderer*	Encapsulates the Draw command, as well as initializing the Graphics class which is a utility class
