示例1: _checkNodeAgainstPortals
void DefaultZone::_checkNodeAgainstPortals(PCZSceneNode * pczsn, Portal * ignorePortal)
{
if (pczsn == mEnclosureNode ||
pczsn->allowedToVisit() == false)
{
// don't do any checking of enclosure node versus portals
return;
}
PCZone * connectedZone;
for ( PortalList::iterator it = mPortals.begin(); it != mPortals.end(); ++it )
{
Portal * p = *it;
//Check if the portal intersects the node
if (p != ignorePortal &&
p->intersects(pczsn) != Portal::NO_INTERSECT)
{
// node is touching this portal
connectedZone = p->getTargetZone();
// add zone to the nodes visiting zone list unless it is the home zone of the node
if (connectedZone != pczsn->getHomeZone() &&
!pczsn->isVisitingZone(connectedZone))
{
pczsn->addZoneToVisitingZonesMap(connectedZone);
// tell the connected zone that the node is visiting it
connectedZone->_addNode(pczsn);
//recurse into the connected zone
connectedZone->_checkNodeAgainstPortals(pczsn, p->getTargetPortal());
}
}
}
}示例2: _updateHomeZone
/* The following function checks if a node has left it's current home zone.
* This is done by checking each portal in the zone. If the node has crossed
* the portal, then the current zone is no longer the home zone of the node. The
* function then recurses into the connected zones. Once a zone is found where
* the node does NOT cross out through a portal, that zone is the new home zone.
* When this function is done, the node should have the correct home zone already
* set. A pointer is returned to this zone as well.
*
* NOTE: If the node does not have a home zone when this function is called on it,
* the function will do its best to find the proper zone for the node using
* bounding box volume testing. This CAN fail to find the correct zone in
* some scenarios, so it is best for the user to EXPLICITLY set the home
* zone of the node when the node is added to the scene using
* PCZSceneNode::setHomeZone()
