Statics

Enemy

using UnityEngine; using System.Collections;  public class Enemy {  //Static variables are shared across all instances  //of a class.  public static int enemyCount = 0;   public Enemy()  {  //Increment the static variable to know how many  //objects of this class have been created.  enemyCount++;  } } 

Game

using UnityEngine; using System.Collections;  public class Game {  void Start ()  {  Enemy enemy1 = new Enemy();  Enemy enemy2 = new Enemy();  Enemy enemy3 = new Enemy();   //You can access a static variable by using the class name  //and the dot operator.  int x = Enemy.enemyCount;  } }

Player

using UnityEngine; using System.Collections;  public class Player : MonoBehaviour {  //Static variables are shared across all instances  //of a class.   public static int playerCount = 0;   void Start()  {  //Increment the static variable to know how many  //objects of this class have been created.  playerCount++;  } } 

PlayerManager

using UnityEngine; using System.Collections;  public class PlayerManager : MonoBehaviour {  void Start()  {  //You can access a static variable by using the class name  //and the dot operator.  int x = Player.playerCount;  } }

Utilities

using UnityEngine; using System.Collections;  public static class Utilities {  //A static method can be invoked without an object  //of a class. Note that static methods cannot access  //non-static member variables.  public static int Add(int num1, int num2)  {  return num1 + num2;  } }

UtilitiesExample

using UnityEngine; using System.Collections;  public class UtilitiesExample : MonoBehaviour {  void Start()  {  //You can access a static method by using the class name  //and the dot operator.  int x = Utilities.Add (5, 6);  } }
