The change in this Body's vertical position from the previous game update.
This value is set during the postUpdate
phase and takes into account the
deltaMax
and final position of the Body.
Because this value is not calculated until postUpdate
, you must listen for it
during a Scene POST_UPDATE
or RENDER
event, and not in update
, as it will
not be calculated by that point. If you do use these values in update
they
will represent the delta from the previous game frame.
The final delta y value.
