C# addendum

Converting the TitleGUI JavaScript to C# was pretty painless:

using UnityEngine;
using System.Collections;

public class TitleGUICSharp : MonoBehaviour {
private float buttonW = 100; // button width
private float buttonH = 50;  // button height
private float halfScreenW; // half of the Screen width
private float halfButtonW; // half of the button width

public GUISkin customSkin;
private void Start()
{
  halfScreenW = Screen.width/2;
  halfButtonW = buttonW/2;
}
private void OnGUI ()
{
 GUI.skin = customSkin;
  if(GUI.Button(new Rect(halfScreenW-halfButtonW, 460,
     buttonW, buttonH), "Play Game"))
  {
      Application.LoadLevel("game");
  }
}
}

Here are the changes:

We declared buttonW and buttonH as floats instead of ints, because the Rect structure later in the code accepts float, and we can't be bothered converting the int values to the float datatype. It's probably simpler and easier for them to begin their lives as floats anyway.

Earlier in our JavaScript code, we separated...
