RDV Bus Events

Bus events are used to update RDV models and AI managers. On a event dispatch, a cascade of processors is called in a loop, where the event's model ID is checked for applicability and then can be further processed:

The typical use case is:

  1. After receiving RMC response, an RDV_cl_ManagerEvent is created and queued by a manager for dispatcher (RDV_cl_Manager::SendBusEvent and RDV_cl_EventDispatcher::AddEvent).
  2. The event is processed by a model's event listener (::OnManagerEvent functions) where it's layout is changed into RDV_cl_BusEvent:
int __thiscall RDV_cl_FriendsModel::OnManagerEvent(int this, RDV_cl_ManagerEvent *manEvent)
{
  id = manEvent->onManagerEventId;
  param1 = manEvent->param1;
  param2 = manEvent->param2;
  result = id;
  switch ( id )
  {
    case 49:                                    // insert new friendData
      event0.modelId = *(this + 4);
      event0.eventId = 0;
      event0.dataParam1 = param2;              // friendData index
      event0.dataParam2 = 0;
      event0.dword10 = 0;
      result = j_RDV_cl_Model::DispatchEvent(this - 4, &mevent0);
      break;
      ...
  1. Event is passed to RDV_cl_Model::DispatchEvent and RDV_cl_EventBus__DispatchEvent where both RDV and AI processors are called as a cascade of updates.
__int64 __thiscall RDV_cl_EventBus::DispatchEvent(RDV::EventBus *this, RDV_cl_ModelEvent *event)
{
  for ( i = this->gearMapItem.dword0; ; i = sub_1000D07B(i) )
  {
    LODWORD(result) = i;
    HIDWORD(result) = i != &this->gearMapItem;
    if ( i == &this->gearMapItem )
      break;
    (**i->j_unknown_libname_214)(i->j_unknown_libname_214, event);
  }
  return result;
  1. Event is processed in applicable processors:
char __userpurge AI_GameSessionModel::OnBusEvent@<al>(int this@<ecx>, double a2@<st0>, double st6_0@<st1>, double a4@<st3>, double a5@<st2>, double a6@<st4>, double a7@<st5>, double a8@<st6>, double a9@<st7>, RDV_cl_BusEvent *busEvent)
{
  // [COLLAPSED LOCAL DECLARATIONS. PRESS KEYPAD CTRL-"+" TO EXPAND]

  eventId = busEvent->eventId;
  gameType = busEvent->dataParam2;
  v64 = busEvent->eventId;
  if ( busEvent->modelId == 1 )                 // user model
  {
    if ( eventId == 6 )
      AI_GameSessionModel::HandleLostConnectionToRDV((this - 8));
    v60 = RDV::Proxy::pUserModel();
    v61 = (v60->pVMT->pRDV_DLL_sub_1000F5E7_CheckPlayerID)(v60);
    LOBYTE(v13) = Yeti::SendClientLoginLogEvent(v61, eventId, gameType);
  }
  else if ( busEvent->modelId == 9 )            // party model
  {
    if ( eventId == 16 )
    {
      v59 = RDV::Proxy::pPartyModel();
      LOBYTE(v13) = (v59->pVMT->p_RDV_sub_1000C0B8_IsPlayerPartyOwner)(v59);
      if ( !v13 )
        LOBYTE(v13) = AI_UIModel::DispatchEvent((this - 8), 27, 0, 0);
    }
    else
    {
    ...
