Building the GameObjectFactory class

It is the job of the GameObjectFactory class 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:

import android.content.Context;
import android.graphics.PointF;
class GameObjectFactory {
    private Context mContext;
    private PointF mScreenSize;
    private GameEngine mGameEngineReference;
    GameObjectFactory(Context c, PointF screenSize, 
                      GameEngine gameEngine) {
        
        this.mContext = c;
        this.mScreenSize = screenSize;
      ...
