I just don't follow what you're saying and it seems to be going in circles. I also have no idea what you mean when you say "nothing goes wrong". If Time.deltaTime and Time.fixedDeltaTimeare identical then it'll enter the loop each and every time only once as it checks >=. Why not just try this yourself rather than trying to convince me this doesn't work. Also, for the final time; please post on another thread. You've effectively took over this thread for your own purposes. Thanks.
