Customizing the GUI

While it is great that Unity provides us with all of this functionality to save us time in creating elements, the actual aesthetics leaves a little to be desired. Thankfully, UnityGUI allows us to customize the appearance of our controls by making use of GUIStyle, which is an optional third parameter to our control functions. If we do not specify a GUIStyle parameter, Unity's default will be used, which is what we experienced last time. This can work fine while testing something out. However, since we're trying to create a polished and complete project, we're going to create one of our own by performing the following steps:

1. Open up the MainMenuGUI script file and modify the function to accommodate the changes in bold:

   using UnityEngine;
   using System.Collections;
   
   public class MainMenuGUI : MonoBehaviour {
     public int buttonWidth = 100;
     public int buttonHeight = 30;
     public GUIStyle titleStyle;
     public GUIStyle buttonStyle;
   
     void OnGUI() 
     {
       ...
