Hoc can i check the time passed in the current frame?

http://answers.unity3d.com/questions/846351/whats-the-best-way-to-get-the-total-time-since-the.html

someone provided an answer, but it doesn't work for me. seems to consistently return too-high values.

is the suggestion wrong, or my implementation?

 

You could have a float defined somewhere in a script on a GameObject that's always active and add Time.deltaTime to it in Update.

 

that would just give me the value of Time.time, with pointless overhead. most of the time functoions only update once per frame

 

Oh I see. I read the linked question and saw you want to check time between operations in 1 frame. That's quite the insignificant amount of time passing

I don't know if it's possible in C#, but my C teacher says for checking things more frequent than 16 milliseconds, you need to learn how clock cycles work and how to measure them in your computer.
