Simple physics engine

This is not bad. Although, it is not normal to see changes along the horizontal while in mid-air. Drag and acceleration should only be allowed while standing on something (just like jump is only allowed while standing on something).

Thanks for ur feedback and this goldstar-thing :P I think ill do a Football game in this next time i have too much freetime, but there are much other projects like my android game (which is alike a mixture of badlands, doodlejump & flappy bird) or my work or my School :D only@danpost: i only implemented the standingOnSmth() because i wanted to show the reusability in other games. U can see the standingOnSmth() is implemented in the Man.class so it isnt necessary for the engine. The aspect in this scenario was to give a quite easy and clean base of a physics engine like i explained (thats why i named the methods exactly alike the things they do).
