animator and yielding for it

Hey 
I am looking for some help with the animator and yielding to it within an enumerator.
 
IEnumerator playAnimation(IContainer game, GameAction action) {
if (LocalPlayerFirst)

anim.Play("Local", 0, 0f);

else

anim.Play("Enemy", 0, 0f);



anim.enabled = true;



while (anim.
isplaying)
yield return null;

//need to do other code after its done


what i am trying to do is tell the animator to yield through  - i tried yield return new waitforseconds(); but that doesnt appear to delay it - really it would be good to finish them move on - i am having trouble finding docs and articles that actually resolve this issue - 

even tried



float continue_time = Time.time + anim.GetCurrentAnimatorClipInfo(0).Length;



while (Time.time < continue_time)

{

 
yield return null;

}

any links would be great and i can go through them
