WaitForEndOfFrame vs Time.frameCount
I'm starting a coroutine inside a monobehaviour, in which I print frame count in the beginning and in the end. In-between I have a WaitForEndOfFrame. Wierdly, the frame counter is the same. How is that possible?
private IEnumerator SampleCoroutine()
{
Debug.Log(Time.frameCount);
yield return new WaitForEndOfFrame();
Debug.Log(Time.frameCount);
}
More wierdly yield return null works correctly here. I saw before this topic https://answers.unity.com/questions/755196/yield-return-null-vs-yield-return-waitforendoffram.html and I thought they are similar and should always return and wait to the next frame.
When you use WaitForEndOfFrame(), you're waiting until the trailing end of the current frame before you resume operation on that coroutine. You're not waiting until the next frame.
By contrast, yield return null; is the standard way of saying "wait until the following frame"
Edit: Essentially, you can think of it like the difference between Update() and LateUpdate() functions. This would be kind've like passing data between them, localized into the coroutine's processing cycle.
