[ARX程序]：求救：关于遍历的一个小问题

lovelyzhaolily

问题：构造选择集，获取选择集里的特征点并充放在数组中，然后在比较特征点在数组中的位置。以下是代码，但结果总是不正确，虽然调试是通了。

请各位帮忙，谢谢！

void zhao_rank()
{
// TODO: Implement the command
int i,cod_number;
int j;
long ilast;
ads_name ent[256];
float coordinate[256][3];

acedSSLength(ssname,&ilast);

AcDbEntity *pEntity;
AcDbObjectId objId;
//*********以下程序是将选择集中实体坐标储存在二维数组***********//
for(i=1;i<ilast+1;i++)
{
  acedSSName(ssname,ilast-i,ent);
  acdbGetObjectId(objId,ent);
  acdbOpenObject(pEntity,objId,AcDb::kForRead);//打开点实体
  
  if(pEntity->isKindOf(AcDbCircle::desc()))
  {
   // 显示圆的圆心
   AcDbCircle *pCircle = AcDbCircle::cast(pEntity);
   AcGePoint3d ptCenter;
   ptCenter = pCircle->center();

   coordinate[0]=ptCenter[X];
   coordinate[1]=ptCenter[Y];
   coordinate[2]=ptCenter[Z];
  }
  if(pEntity->isKindOf(AcDbPoint::desc()))
  {
   // 显示点的坐标
   AcDbPoint *pPoint = AcDbPoint::cast(pEntity);
   AcGePoint3d ptPoint;
   ptPoint = pPoint->position();

   coordinate[0]=ptPoint[X];
   coordinate[1]=ptPoint[Y];
   coordinate[2]=ptPoint[Z];
  }
  pEntity->close();
}

//*********以下程序是为实体标号***********//
for(i=1;i<ilast+1;i++)
{
cod_number=1;
acedSSName(ssname,ilast-i,ent);
acdbGetObjectId(objId,ent);
acdbOpenObject(pEntity,objId,AcDb::kForRead);//打开点实体
if(pEntity->isKindOf(AcDbCircle::desc()))
{
  AcDbCircle *pCircle = AcDbCircle::cast(pEntity);
  AcGePoint3d ptCenter;
  ptCenter = pCircle->center();
  for(j=1;j<ilast+1;j++)
  if(ptCenter[Y]<coordinate[j][1]||(ptCenter[Y]==coordinate[j][1]&&ptCenter[X]<coordinate[j][0]))
   cod_number=cod_number+1;
  acutPrintf("\n %d",cod_number);
}
if(pEntity->isKindOf(AcDbPoint::desc()))
{
  AcDbPoint *pPoint = AcDbPoint::cast(pEntity);
  AcGePoint3d ptPoint;
  ptPoint = pPoint->position();
  for(j=1;j<ilast+1;j++)
   if(ptPoint[Y]<coordinate[j][1]||(ptPoint[Y]==coordinate[j][1]&&ptPoint[X]<coordinate[j][0]))
    cod_number=cod_number+1;
   acutPrintf("\n %d",cod_number);
}


}
acedSSFree(ssname);
}

我也正在痛苦中
