class GalaxyEggbertApp : public Urho3D::Application {
    URHO3D_OBJECT(GalaxyEggbertApp, Urho3D::Application);

    explicit GalaxyEggbertApp(Urho3D::Context* context);
    void Setup() override;
    void Start()  override;
    void Stop()   override;
    void GameUpdate(float dt);
    void HandleUpdate(Urho3D::StringHash, Urho3D::VariantMap&);
private:
    std::unique_ptr<GalaxyEggbertGame> game_;
};

Methods

Setup()

Called by Urho3D before engine initialization. Sets engine parameters:

• Window title: "Galaxy Eggbert"
• Size: 1280×720, not full screen
• Resource paths: Data;CoreData;Content
• Log file: GalaxyEggbert.log

Start()

Called after engine initialization. Creates GalaxyEggbertGame and subscribes to the E_UPDATE event.

HandleUpdate(eventType, eventData)

Event handler for E_UPDATE. Extracts the timestep from eventData[P_TIMESTEP] and calls GameUpdate(dt).

GameUpdate(float dt)

Delegates to game_->Update(dt) if the game object exists.

Stop()

Called on shutdown. Resets game_ (triggers GalaxyEggbertGame::Stop() and save-write).

Ownership

Owns game_ as a std::unique_ptr<GalaxyEggbertGame>. The game is created in Start() and destroyed in Stop().
