Call After Delay - handy Unity3D coroutine to do something later

CallAfterDelay.cs

using UnityEngine;
using System.Collections;

public class CallAfterDelay : MonoBehaviour
{
	float delay;
	System.Action action;

	// Will never call this frame, always the next frame at the earliest
	public static CallAfterDelay Create( float delay, System.Action action)
	{
		CallAfterDelay cad = new GameObject("CallAfterDelay").AddComponent<CallAfterDelay>();
		cad.delay = delay;
		cad.action = action;
		return cad;
	}

	float age;

	void Update()
	{
		if (age > delay)
		{
			action();
			Destroy ( gameObject);
		}
	}
	void LateUpdate()
	{
		age += Time.deltaTime;
	}
}
