The following snippet shows how to add a static property called "instance" that will automatically find an instance of the class in the scene and return it.

This is useful for managers and other behaviours that only have one instance in the scene, that need to be accessed from other classes, as it avoids having each class to keep a reference to the manager object.


using UnityEngine;
using System.Collections; 

/// AManager is a singleton.
/// To avoid having to manually link an instance to every class that needs it, it has a static property called
/// instance, so other objects that need to access it can just call:
///		AManager.instance.DoSomeThing();
///
public class AManager : MonoBehaviour {
	// s_Instance is used to cache the instance found in the scene so we don't have to look it up every time.
	private static AManager s_Instance = null;

	// This defines a static instance property that attempts to find the manager object in the scene and
	// returns it to the caller.
	public static AManager instance {
		get {
			if (s_Instance == null) {
				s_Instance =  FindObjectOfType(typeof (AManager)) as AManager;
				if (s_Instance == null)
					Debug.LogError ("Could not locate a AManager object. You have to have exactly one FactionCardMgr in the scene.");
			}
			
			return s_Instance;
		}
	}
	
	// Add the rest of the code here...
	public void DoSomeThing() {
		Debug.Log("Doing something now", this);
	}
 
}
