Diving, long jumping, and triple jumps are pretty simple, as diving you jump test marioVelocity.magnitude to see if he is fast enough to perform a dive when the player presses 'B' otherwise kick or punch, long jumps if the player is crouching, has some velocity, and presses 'A', and triple jumps you just have a float that goes down, and when Mario lands again he has a short time to press 'A' to perforom a double or triple jump.
