Talk:HowTo/Search for objects in the world

Script error in lines 12, 17, 23: The pointer variable asyncSearch has to be searchObj.

Or vice versa in lines 3, 6, 31: The pointer variable searchObj has to be asyncSearch

P.S. For some reason I don't know yet, I'm no more able to edit the main page? For other pages I#m able. Is there some reason I don't know why?

Correct Async Object Search Sample Code

thread void TrainSearch(void)
    {
         // prevent multiple threads
         if(m_bIsThreadedFunctiionRunning) return;

         // Start a search for any traincars within the world
         AsyncObjectSearchResult searchObj = World.GetNamedObjectList(AssetCategory.TrainCar, "");
         
         // Sniff for search related messages, and then wait for either completion or failure
         Sniff(searchObj, "ObjectSearch", "", true);
         Message msg;
         wait()
         {
              on "ObjectSearch", "Failure", msg:
                   if (msg.src == searchObj)
                   continue;
                   Interface.Log("Search error " + searchObj.GetSearchErrorCode());
                   break;
              on "ObjectSearch", "AsyncLoadComplete", msg:
                   if (msg.src == searchObj)
                   continue;
         };
         
         // Check the results
         int errCode = searchObj.GetSearchErrorCode();
         if (errCode != AsyncObjectSearchResult.ERROR_NONE)
         {
              // TODO: Add any error handling here, such as waiting and reattempting the
              // search later, showing an error message, throwing script exceptions, etc.
                   Interface.Log("WaybillTracker:: ERROR during async object search");
                   m_bIsThreadedFunctionRunning = false;
              return;
         }
         
              // Get the search results
              NamedObjectInfo[] results = searchObj.GetResults();
              
              // TODO: Add any processing of the results here
              string successmsg = "WaybillTracker:: Size of results of async object search" + results[0].localisedUsername;

              Interface.Log(successmsg);
              m_bIsThreadedFunctionRunning = false;
    }

    NamedObjectInfo[] contains 4 properties:
       GameObject      objectRef;   Holds reference to object 'IF' loaded. Reference may go out of scope and be lost, for long term storge GameObjectId should be used. A call to Router.DoesGameObjectStillExist() should be called before accessing the GameObject reference.
       GameObjectId    objectId; Currently the safest to use for long term storage of objects. May be subject to change in the future.
       string          localisedUsername;  Localized display name for the object.
       string          categoryString;    The asset category of the current object.
