Substitute the '-1' above for an Acceleration-Due-To-Gravity value based on whatever units fit your gameworld.
The SI value 'g' varies slightly due to the oblateness of the earth and the value changes from 9.789 to 9.823 ms-2 (where the higher value reflects a polar 'g' and the lower value would be equatorial.)
Use TranslateEntity just for gravity, because Gravity always acts Globally downwards, but of course, use MoveEntity for general control and movement because this will be relatively Local.
