refilter method
void
refilter()
Call this if you want to establish collision that was previously disabled by ContactFilter.shouldCollide.
Implementation
void refilter() {
// Flag associated contacts for filtering.
for (final contact in body.contacts) {
final fixtureA = contact.fixtureA;
final fixtureB = contact.fixtureB;
if (fixtureA == this || fixtureB == this) {
contact.flagForFiltering();
}
}
// Touch each proxy so that new pairs may be created
final broadPhase = body.world.contactManager.broadPhase;
for (var i = 0; i < _proxyCount; ++i) {
broadPhase.touchProxy(proxies[i].proxyId);
}
}
