setTransform method
Set the position of the body's origin and rotation. This breaks any contacts and wakes the other bodies. Manipulating a body's transform may cause non-physical behavior. Note: contacts are updated on the next call to World.step().
Implementation
void setTransform(Vector2 position, double angle) {
assert(!world.isLocked);
transform.q.setAngle(angle);
transform.p.setFrom(position);
sweep.c.setFrom(Transform.mulVec2(transform, sweep.localCenter));
sweep.a = angle;
sweep.c0.setFrom(sweep.c);
sweep.a0 = sweep.a;
final broadPhase = world.contactManager.broadPhase;
for (final f in fixtures) {
f.synchronize(broadPhase, transform, transform);
}
}
