engine::Application class
#include <include/engine/core/application.h>

Represents the client application that runs on top of the engine.

The client is expected to subclass Application and override the lifecycle methods.

Constructors, destructors, conversion operators

~Application() defaulted virtual: Virtual destructor is crucial for proper inheritance cleanup.

void Run(): Drives the main game loop.
void OnInit() pure virtual: Called once when the application starts.
void OnShutdown() pure virtual: Called once when the application is about to close.
void OnUpdate(double delta_time_seconds) pure virtual: Called every frame.

auto window() -> Window&: Provides access to the main application window.
auto input_manager() -> InputManager&: Provides access to the input manager for handling keyboard and mouse events.
auto main_camera() -> engine::graphics::Camera&: Provides access to the primary camera used for rendering the scene.

Drives the main game loop.

This method will continuously call OnUpdate until the application is terminated.

Called once when the application starts.

This is the ideal place for one-time initialization code, such as loading assets.

Called once when the application is about to close.

Use this for cleanup code.

Called every frame.

Parameters
delta_time_seconds	The time elapsed since the last frame, in seconds. This value should be used for frame-rate independent physics and animations.

Game logic and rendering should be handled here.

Provides access to the main application window.

Returns	Reference to the Window.

Provides access to the input manager for handling keyboard and mouse events.

Returns	Reference to the InputManager.

Provides access to the primary camera used for rendering the scene.
