Pause Menu Script!

Here's a script that's extremely similar to the main menu script. It's for the pause menu in the tutorial that's on YouTube right now!

var menuHeight:float=500;
var menuWidth:float=500;
var buttonSpacing:float=25;
var mainMenu: String = "MainMenu";
var titleTexture:Texture2D;
var customSkin:GUISkin;
var customStyle:GUIStyle;

function OnGUI(){
GUI.skin = customSkin;
GUILayout.BeginArea(Rect(Screen.width/2-menuWidth/2,Screen.height/2-menuHeight/2,menuHeight,menuWidth),customStyle);
GUILayout.Space(50);
GUILayout.Label(titleTexture);
GUILayout.Space(buttonSpacing);
if(GUILayout.Button("Main Menu")){
Application.LoadLevel(mainMenu);
}
GUILayout.Space(buttonSpacing);
if(GUILayout.Button("Exit to Desktop")){
Application.Quit();
}
GUILayout.Space(buttonSpacing);
GUILayout.EndArea();
}
