I have a simple game with 20-30 bodies (static, and dynamic)
If I add some more Dynamic bodies and joints (over 80-90 item), then the Box2D will be very laggy, and a little slow..
Am I doing something wrong, or this is the limit of JBox2D? If I change to Box2D JNI via java native calls, is will be faster?
As I heard the fastest implementation of Box2D for Android is there: http://code.google.com/p/libgdx/
AndEngine is using that implementation instead of jBox2D and they’re happy they switched to that version 🙂
