GalaxyEggbertCnaGame

CNA Game subclass — the entry point and per-frame driver of GalaxyEggbertCNA.

Overview

GalaxyEggbertCnaGame (namespace GalaxyEggbert::CNA) subclasses Microsoft::Xna::Framework::Game, CNA's XNA-compatible game base class. It owns the world runtime, terrain renderer, tile atlas, texture, effect, Blupi controller, and camera.

Sources: src/GalaxyEggbertCNA/GalaxyEggbertCnaGame.hpp and .cpp, constructed from src/GalaxyEggbertCNA/main.cpp.

Construction

Sets the window title via getWindowProperty().setTitleProperty("Galaxy Eggbert (CNA)").

Overridden Methods

LoadContent()

• Loads the default world: worldRuntime_.LoadFromVwrFile("worlds3d/world001.vwr").
• Builds a GETerrainRenderer from the loaded world plus a GETileAtlas.
• Loads Content/icons/object-m.png as a CNA Texture2D.
• Creates a BasicEffect with VertexColorEnabled=false, TextureEnabled=true, bound to that texture.
• Places GEBlupiController at spawn (0, 1, 0).

Update(GameTime& gameTime)

• Calls Game::Update.
• Advances worldRuntime_.Update(dt) — drives the 6 fps tile-animation phase.
• Reads Keyboard::GetState() for arrow keys + Space.
• Steps blupi_.Step(world, dx, dz, jump, dt).
• Updates the CnaEngine::Graphics::Camera to follow Blupi (SetLookAt(position, target)); the game keeps the look-at target itself in cameraTarget_. Until 2026-10-20 this was an Easy3D::Camera3D (SetTarget/SetPosition).

Draw(const GameTime& gameTime)

• Clears the device to sky blue (0.392, 0.584, 0.929, 1.0).
• Enables depth test.
• Sets the terrain effect's View/Projection from the camera (camera_.View()/camera_.Projection()), World to identity.
• Calls terrainRenderer_->Draw(device, *terrainEffect_).
• Includes a one-shot terrain-visibility self-check that samples backbuffer pixels via GetBackBufferData().

What This Class Does Not Do

No phase/state-machine dispatch, no HUD, no sound, no object rendering, no Blupi sprite. It is purely: load one world, render its terrain, move an invisible collision point through it.

Dependencies

• CNA: Game, GameTime, Texture2D, BasicEffect, Keyboard/Keys
• cna-engine (CnaEngine::Graphics): Camera (until 2026-10-20: Easy3D::Camera3D)
• GEWorldRuntime, GETerrainRenderer, GETileAtlas, GEBlupiController
