Utilizing specific entities within a buffer

[StudentHelp]

Hello,

I have a buffer named Stockpile that holds many entities. I am trying to sort through the stockpile to see if the entities have expired. I have used the following code:

 i := Stockpile.NumMU;
 if i>0 then
  Repeat
   if EventController.SimTime - Stockpile.MU(i).TimeCreated > 31449600 then
    Stockpile.MU(i).move(BufferExpired);   
   end;
   i := i - 1;
  until Stockpile.NumMU=0 OR i=0;
 end;

But I am worried Buffer.NumMU doesnt correctly refer to the entities. If there are currently 5 entities within the buffer but these entities are entity number 10, 11, 12, 13, 14 - wont Buffer.NumMU return 5? Thus none of the entities will be reffered to?

Any help around this would be appreciated!

Hi,

To access the MUs in an Buffer, you can try using "contentslist" attribute.Try the following code

for var i :=1 to buffer.contentslist.ydim

    part := buffer.contentslist[1,i]

    if part.<attribute> = expires then

           part.move(BUffer expired>

   end

next

Also you'll need to update/carry the information on the MUs, so as to identify it as expired.

Hope this helps.

Thank you Varun. Another solution I thought of is:

 i := Stockpile.statNumIn;
 j := Stockpile.NumMU;
 if j>0 then
  Repeat
   if EventController.SimTime - Stockpile.MU(i).TimeCreated > 31449600 then
    Stockpile.MU(i).move(BufferExpired);   
   end;
   j := j - 1;
   i := i - 1;
  until j=0;
 end;

This will find the maximum .MU(i), thus the last entity created. Do you agree?

Hi,

as Varun_B already said, you need to access the contentlist of the buffer. For your method it means the following:

 i := Stockpile.NumMU;

 if i>0 then
  for local x:= i downto 1 
   if EventController.SimTime - Stockpile.contentlist[1,i].TimeCreated > 31449600 then
    Stockpile.contentlist[1,i].move(BufferExpired);   
   end;
    i := i - 1;
  next;
 end

Stockpile.MU(i) is not refering the the position of the MU in the pile.
