sorry if the title’s unclear (it’s unclear in my mind also lol) but basically what I’m trying to create is a custom timer that uses frames rather than milliseconds.  
But I can’t figure out how functions like setInterval calls the function you passed along with the arguments.  
First I create a reference to the function I want to execute after a certain interval and name it fc, then I create a list of arguments my function want to pass using Array, but then how do I put those arguments in fc()?

thanks
