Making a Flickering Light Without Yield WaitForSeconds

So I am trying to create a script that explodes a missile OnCollisionEnter2D. So far I have this script:

1. var delay :float=2;
2. functionOnCollisionEnter2D()
3. {
4. light.enabled =true;
5. rigidbody2D.velocity =Vector2(0,0);
6. animator.SetBool("missileCollision",true);
7. yieldWaitForSeconds(delay);
8. Destroy(gameObject);
9. }

Now I want to add a flickering light effect. The problem is that I can only figure out how to do it using 'yield WaitForSeconds' (http://forum.unity3d.com/threads/flickering-light.4988/). This causes further delay to the Destroy(gameObject) due to there being multiple 'yield WaitForSeconds' statements, which I do not want. Is there another way to accomplish this??

 

Yes... Start another coroutine. http://docs.unity3d.com/ScriptReference/MonoBehaviour.StartCoroutine.html

 

Awesome, didn't know what those were before now. Thanks for the tip!
