When you jump up in the air, do you continue flailing your legs as if you're still running, or do you stay in some sort of jump pose?
Even though I'm sure many of you would like to say "flail your legs" for the lulz, the answer is: jump pose.
Here we're going to add in a Mario sprite that only activates when Mario is in the air. It may seem easy at first thought, but the way in which we're going to switch Mario into this pose is a little different from how we switched him between standing and running.
We're also going to switch our Deekay Tool space character out with a Mario sprite that I illustrated, just so we can get some sprite sheet characters that are evenly spaced for when we proceed to the next video which contains some heavy collision detection related concepts.
