A few questions about "delta seconds"

@cfry

1. Am I correct in that delta time is the time in between ticks

yes

and a tick is equal to fps?

no, a tick it is more like spf - seconds per frame (how many seconds - or rather how large a fraction of one - it took to render the frame)

And basically fps*tick=1 (unless the game slows down or speeds up), so it is easy to calculate one when you know the other (which is why the BP below works)
