Using calculation modes

- [Instructor] Just like view animations and transitions,…key frame animations have their own option effects.…Let's go to the top of our bounce image view with key frames…and into the options parameter…for our overarching key frame animation.…Right now we've only got repeat…so we're going to add a comma and use dot notation…to start looking at each option.…Now all of our options start with calculation…so we can see here that we have five modes.…CalculationModeCubic, Paced,…Linear, Discreet and CubicPaced.…

Now let's start with Linear…since this deal with how to interpolate…or move between each key frame.…Let's save this and run and see how our animation changes.…All right now we won't see too much difference…with the linear calculation mode…because our animation is already fairly smooth and even.…However let's replace calculationModeLinear…with calculationModeDiscreet.…

Now Discreet is simply going to jump from…key frame to key frame without any easing at all.…So in essence Discreet and Linear modes…are the opposite sides of the same coin.…
