示例1: InRangeOfThreat
bool CFerianShipAI::InRangeOfThreat (CSpaceObject **retpThreat)
// InRangeOfThreat
//
// Returns the nearest threat
{
if (m_pShip->IsDestinyTime(19))
{
CSystem *pSystem = m_pShip->GetSystem();
int iDestiny = m_pShip->GetDestiny();
// Get the list of objects that intersect the object
SSpaceObjectGridEnumerator i;
pSystem->EnumObjectsInBoxStart(i, m_pShip->GetPos(), MAX_THREAT_DIST);
// Loop over all objects
Metric rNearestDist2 = MAX_THREAT_DIST * MAX_THREAT_DIST2;
CSpaceObject *pNearestObj = NULL;
while (pSystem->EnumObjectsInBoxHasMore(i))
{
CSpaceObject *pObj = pSystem->EnumObjectsInBoxGetNext(i);
// If the object is in the bounding box then remember
// it so that we can do a more accurate calculation.
if (pObj->GetCategory() == CSpaceObject::catShip
