Checking for input by using Update or a Coroutine - is there a timing difference?
I was just looking at a project's code and saw that it uses a coroutine for checking for input. Is there a functional difference between the following?
private IEnumerator WaitForTap()
{
while (true)
{
if (Input.GetMouseButtonDown(0))
{
//do something
}
yield return 0;
}
}
or
void Update()
{
if (Input.GetMouseButtonDown(0))
{
//do something
}
}
Say that I would want to record the timestamp of the tap in //do something - would there be a difference in precision between the two?

I'm not sure if Input updates mid frame (I suspect it does not). If it does though, assuming your game is running at 60fps, you're talking about a difference of 16 thousandths of a second. The top version is simpler and less error prone. I'd go with it.
