What character touched in its last update.

Implementation

@override

  if (!_myCharacter(character)) return const [];

    final needed = _characterState.ref.contactCount;
    if (needed > _contactCapacity) {

      _contactCapacity = needed;
      _contacts = _alloc<JJ_CharacterContact>(_contactCapacity);
      n = jj_character_contacts(character, _contacts, _contactCapacity);
    }
  }
  return [

      () {
        final c = _contacts[i];
