[ODE] character jumping

[Megan Fox]

It's worth mentioning that, in practice, using the standing state as
your only gate to jumping is dangerous to consistency.  Depending on
terrain, whether you were in motion and bouncing a little when you
started, etc, your feet can lose contact faster in one circumstance
than another, resulting in differing jump heights.

Even ignoring that, I found that the window between jump initiation
and feet leaving the ground wasn't enough time to allow for much
difference between a quick tap short jump and a held high jump, and
felt a little funny until I almost doubled the valid "jump time."


... granted, this all depends on what sort of game you're making.  If
you're working on a platformer/action or semi-acrobatic FPS project,
these tweaks are useful.  If you're working on a game where the jump
is largely for show and needn't be incredibly responsive, this amount
of effort is largely wasted.
