Create include and hook to a CreateDynamicObject function, keep track of maximum object id and objects count...
You can also hook to a DestroyDynamicObject function and if destroyed object is the last one (maximal id) then loop back and check for valid objects (first one valid object is new maximal id)

EDIT: just visited streamer topic to check natives. And these came to my mind

EDIT: Noticed insane mistake i made (rush), fixed it now

pawn Код:

new objectscount = CountDynamicObjects();
new i = 0;
while(objectscount > 0)
{
    if(IsValidDynamicObject(i))
   {
        //Do what you need here, but i++ goes in the end of the IF function

        objectscount--;
    }
    i++;
}
