animation won't finish when using coroutine

my animation will not play all the way through to simulate running when the right/left arrow
key is pressed so i tried to use a coroutine to fix the problem by making the animation wait 1 second and to try to get it to play all the way through but it did not work.
I checked debugging to the console but it said it was waiting the 1 second but the animation did not show it when i went into play mode

I have a bool (isRunning) set up to only allow the animation to be run but it also does not seem to be helping.

Here is the code that I have:

// This is inside the Update() function

float leftrightButtonPush = Input.GetAxis ("Horizontal");
if (Mathf.Abs (leftrightButtonPush) > 0.2f && !isRunning) {
StartCoroutine (Run (leftrightButtonPush));
} else if ( leftrightButtonPush < 0.2f) {
//anim.SetFloat("speed", Mathf.Abs (leftrightButtonPush));
}



}


IEnumerator Run(float val ){
Debug.Log ("hi");
isRunning = true;
//yieldreturnnewWaitForSeconds (0.5f);
anim.SetFloat("speed", Mathf.Abs (val));
yieldreturnnewWaitForSeconds (1f);
isRunning = false;
Debug.Log ("bye");
}

 

if you put above code in update , so you are calling IEnumeratorRun in each frame that player use left or right.

call IEnumeratorRun just once . may Input.getkeyDown can help.

 

Based on the isRunning (bool) variable, IENumerator should only be called once.
Yet, it's clearly being run every time the Update() function gets executed.

Any suggestions?
