Gravity and Physics in Java 2 ME

[SameHendx]

Hy everibody! I'm creating game with balls and I have a problem with gravity and physics. How to create it ?

Its easier to bring gravity simulation into you game. However, the best solution is Box2D or other Java based physics engines.

Thanks, but where I can get Box2D

[DevelopmentTeam]

You have lots of other Physics engine that are ported to J2ME. Just do a google "j2ME Physics engine"

It's easy with physcis engines but I want to myself good physsics

The simplest way to simulate physics for objects...

All objects will have (int) x, y, (float) forcex, forcey

Calculations for each frame:
object[i].x += forcex;
object[i].y += forcey;
object[i].forcex -= 0.5; (you can alter this 0.5 to your preference)
object[i].forcey -= 0.5; (you can alter this 0.5 to your preference)
object[i].y -= gravity; (Tune this gravity to make it look realistic)
