Coroutine not firing

Questions & Answers
1

So I have an issue with a coroutine that is simply not firing.

IEnumerator EnterMenu()
{
    //some other code
    Debug.Log ("camera swap");
    Debug.Log (ScreenWipe.use == null);
    yield return ScreenWipe.use.CrossFade (gameCamera.camera, menuCamera.camera, 2.5f);
    Debug.Log ("camera swap finish");
    //some other code
}

I call EnterMenu like this and all of the other yields work fine.

StartCoroutine (EnterMenu());

The code for the screen wipe is from this

However, I am using a modified C# version because the JS version was not working. I have modified the CrossFade code shown below:

public IEnumerator CrossFade ( Camera cam1, Camera cam2, float time )
{
    Debug.Log("CrossFade() begun");
	yield return CrossFade( cam1, cam2, time, null );
}

The issue is, “CrossFade() begun” does not get written to the log. The output looks like this:

camera swap

False

camera swap finish

Any ideas?

I found the fix if anyone else has the issue, I had to call StartCoroutine for each sub routine that was being called. See below:

IEnumerator EnterMenu()
{
    //some other code
    Debug.Log ("camera swap");
    Debug.Log (ScreenWipe.use == null);
    yield return StartCoroutine(ScreenWipe.use.CrossFade (gameCamera.camera, menuCamera.camera, 2.5f));
    Debug.Log ("camera swap finish");
    //some other code
}

I call EnterMenu like this and all of the other yields work fine.

StartCoroutine (EnterMenu());

The code for the screen wipe is from this

public IEnumerator CrossFade ( Camera cam1, Camera cam2, float time )
{
    Debug.Log("CrossFade() begun");
	yield return StartCoroutine(CrossFade( cam1, cam2, time, null ));
}
