Member Function Documentation

Start()

void JadeEngine::PoweredByJadeEngineScene::Start ( )

overridevirtual

Triggered the first time this scene is played.

An ideal callback to initialize the scene's game objects. Only triggered once, i.e. second call to GGame.PlayScene with this scene will not trigger Start(). Start() will be triggered immediately when GGame.PlayScene is called while the first Update() will happen next frame.

Game::PlayScene

void GameScene::Start() //override
{
  // Assuming GameScene has `Button* _button` and `float _timer` members and we have filled `ButtonParams buttonParams` variable.
  _button = GGame.Create<Button>(buttonParams);
  _timer = 5.0f;
}

Reimplemented from JadeEngine::IScene.

Update()

void JadeEngine::PoweredByJadeEngineScene::Update ( )

overridevirtual

Triggered every frame by the Jade Engine while this scene is active.

To obtain delta time since last frame use GTime.deltaTime.

The trigger order is the following: IScene::PreUpdate -> IGameObject::Load -> IGameObject::Update -> IScene::Update -> IGameObject::Load -> IGameObject::Render.

  // Assuming the scene contains `float _timer` member variable initialized to certain amount of time in seconds
  _timer -= GTime.deltaTime;
  if (_timer < 0.0f)
  {
    // Timer expired, do something
  }
}
