Building the GameObjectFactory

It is the job of the GameObjectFactory to use the ObjectSpec based classes to assemble GameObject instances with the correct components.

Create a new class called GameObjectFactory and add the following members and constructor shown next.

class GameObjectFactory {
    private Context mContext;
    private PointF mScreenSize;
    private GameEngine mGameEngineReference;

    GameObjectFactory(Context c, PointF screenSize, 
                      GameEngine gameEngine) {
        
        this.mContext = c;
        this.mScreenSize = screenSize;

    }
}

We have a Context object, a PointF to hold the screen resolution and a GameEngine object to hold a reference to the GameEngine class. In the constructor all these member variables are initialized. It is ...
