For example, suppose my main character is a ghost that floats, and I would like to make the ghost "dive" down to the ground (platform) and then return to the same height from which he started. I basically want to reverse the jump. This would be reversing the direction of a normal jump that is performed by clicking (in my example).
Another example would be that of a swimming fish. I want the jump command to arch the fish down and then back to its original starting height.
Any tips would be greatly appreciated. I can't attach a CAPX but was just "fishing" for suggestions. (Pun intended)
Another way to ask this question would be: Can movement be completely reversed? In case I wanted to introduce a level where up is down and down is up.
