Game Scenes

Start off by declaring the header file and including all the objects you'll need for this scene.

#include <RuneEngine.h>
#include "player.h"
#include "floorTile.h"
 
class FirstLevel : public rune::GameScene
{
 
private:
 
  //Add a player object
  Player playerObject;
 
  //Create the scene floor
  FloorTile groundTile1;
  FloorTile groundTile2;
 
  rune::Camera sceneCamera;
 
 
};

After you have all of these objects added in the header, go ahead and instantiate the objects in the scene by creating a doInit(void) function.

public: 
  virtual void doInit(void) override;

Then in this function you can add objects to scene, set up cameras, change positions of objects, and anything else you could normally do with a rune::GameObject.

void FirstLevel::doInit(void)
{
  //Change the color that the screen will be cleared with.
  clearColor = rune::Color(49,77,121);
 
  //Add player object
  addObjectToScene(playerObject)
 
  //Add the floor to the scene
  addObjectToScene(groundTile1);
  addObjectToScene(groundTile2);
 
  //Change the position of each object independently.
  m_groundTile1.transform.setPosition(rune::Vec3(0,0));
  m_groundTile2.transform.setPosition(rune::Vec3(128, 0));
 
  //Set up the camera
  SceneCamera.setZoom(2.5);
  SceneCamera.setCenter(rune::Vec2(m_player.transform.getPosition().x+180, m_player.transform.getPosition().y+30));
  getGameInstance()->getWindow()->setCamera(sceneCamera);
}

And now you should have your first rune::GameScene up and running! All that's left to do is add it to your rune::GameApplication in your main function.
