示例1:
//-----------------------------------------------------------------------------
// Purpose: Finds the first entity within radius distance by class name.
// Input : pStartEntity - The entity to start from when doing the search.
// szName - Entity class name, ie "info_target".
// vecSrc - Center of search radius.
// flRadius - Search radius for classname search, 0 to search everywhere.
// Output : Returns a pointer to the found entity, NULL if none.
//-----------------------------------------------------------------------------
CBaseEntity *CGlobalEntityList::FindEntityByClassnameWithin( CBaseEntity *pStartEntity, const char *szName, const Vector &vecSrc, float flRadius )
{
//
// Check for matching class names within the search radius.
//
CBaseEntity *pEntity = pStartEntity;
float flMaxDist2 = flRadius * flRadius;
if (flMaxDist2 == 0)
{
return gEntList.FindEntityByClassname( pEntity, szName );
