So... Spent another year or so without a computer.

Uhg my pong code I scavenged from the forums quickly went from 6 simple source files to 18 files total including headers.

UPDATE:

Managed to abstract the ball and paddle classes into the "Renderable_Object" class.

Code:

#ifndef RENDERABLE_OBJECT_H
#define RENDERABLE_OBJECT_H
#include "Vector2.h"
class Renderable_Object
{
public:
	Vector2 & getVelocity()
	{
		return velocity;
	}
	Vector2 & getPosition()
	{
		return position;
	}
	Vector2 & getMinimum()
	{
		return d_min;
	}
	Vector2 & getMaximum()
	{
		return d_max;
	}
private:
	Vector2 position;
	Vector2 velocity;
	Vector2 d_min;
	Vector2 d_max;
	bool isPhysical;
	bool isVisible;
};

#endif

Which now allows me to centralize the rendering process, like so!

Code:

#include "Renderable_Object.h"

class Renderer
{
	void draw(Renderable_Object object)
	{
		glPushMatrix();
		glTranslatef(object.getPosition().x,object.getPosition().y,-50.0f);
		glBegin(GL_QUADS);						// Start Drawing Quads
			glVertex3f(object.getMinimum().x, object.getMinimum().y,  1.0f);	// Bottom Left Of The Texture and Quad
			glVertex3f( object.getMaximum().x, object.getMinimum().y,  1.0f);	// Bottom Right Of The Texture and Quad
			glVertex3f( object.getMaximum().x,  object.getMaximum().y,  1.0f);	// Top Right Of The Texture and Quad
			glVertex3f(object.getMinimum().x,  object.getMaximum().y,  1.0f);	// Top Left Of The Texture and Quad
		glEnd();
		glPopMatrix();
	}
};

I just eliminated 4 useless files and 2 classes! HURRAH!
