fps = frames per second, f/s
timedelta = time elpsed per frame (in seconds), seconds per frame, s/f
1/ (60 [f/s]) = (1/60)[s/f]
if you were moving 1 pixel per frame at locked 60fps, in 60 frames you moved 60 pixels
Thus:
Always-- object Set Y to object +1
Becomes:
Always-- object Set Y to object +(60*Timedelta)
and this:
Always-- object Set Y to object +5
Becomes:
Always-- object Set Y to object +(5*60*Timedelta)
that is, assuming you were running at locked 60fps.
