are you calling contact.setIndex(i); whereby the i is the int in a loop looping through the contacts in a collision?
This is what i do:
for (int i = 0; i < collision.getContactCount(); i++) {
// set the index
contact.setIndex(i);
contact.setMode(Ode.dContactBounce | Ode.dContactApprox1);
contact.setBounce(0.4f);
contact.setBounceVel(1f);
contact.setMu(100f);
}
The dBounce stuff shouldn’t affect your problem. Its mainly the contact.setIndex…
