I'm pretty sure this question is NP-complete @_@want to bring up a question i raised months ago that never got an answer:
does anyone know the equation for the vertical component of acceleration / velocity / position for DJL characters like peach, so that we can figure out the best timing between the two jump inputs to reach the highest possible point in the least amount of time? we've all been doing it off of 'feel' since the game came out, it would be good to confirm.
I know each double jump character has a unique velocity for each frame of their double jump that doesn't seem to have a set pattern and values are rather strange.
Finding a solution would depend on the height of the opponent off the ground as well. As Peach, the timing for the double jump to land dtilt->uair would depend on Sheik's percent and DI.
I can imagine how to write a program that would exhaustively calculate the max height achievable given a certain number of frames. Maybe I'll do that.
