setType method

void setType(BodyType type)

Set the type of this body. This may alter the mass and velocity.

Implementation

void setType(BodyType type) {
  assert(!world.isLocked);
  if (_bodyType == type) {
    return;
  }

  _bodyType = type;

  resetMassData();

  if (_bodyType == BodyType.static) {
    linearVelocity.setZero();
    _angularVelocity = 0.0;
    sweep.a0 = sweep.a;
    sweep.c0.setFrom(sweep.c);
    synchronizeFixtures();
  }

  setAwake(true);

  force.setZero();
  _torque = 0.0;

  // Delete the attached contacts.
  while (contacts.isNotEmpty) {
    world.contactManager.destroy(contacts.first);
  }
  contacts.clear();

  // Touch the proxies so that new contacts will be created (when appropriate)
  final broadPhase = world.contactManager.broadPhase;
  for (final f in fixtures) {
    final proxyCount = f.proxyCount;
    for (var i = 0; i < proxyCount; ++i) {
      broadPhase.touchProxy(f.proxies[i].proxyId);
    }
  }
}
