Recognizing the most recently added inventory item


integer x = llGetListLength(listofitems); // the list that we are keeping track of
string mostrecentitemname = llList2String(listofitems,x) - 1;

list origList; // initially set to contents of object then reset each time the compare process is finished

list newList; // holds current contents when addition of inventory item already has started

list workingList; // list you maintain and add the new items as you get them so that the last list item is always your newest
 
comparefunction()
{
    origList = ["a","c","b"];
    newList = ["a","d","b","c"];

    //then you would have some compare logic right here to find out that "d" is the item added...

    workingList = origList + newListItem;
     
    // each time this process is run you always need a snapshot of what the inventory looks like prior to adding an inventory item
   // this is what i was talking about before needing the global variable for
    origList = newList; 
}

comparefunction();

integer x = llGetListLength(workingList ); // the list that we are keeping track of
string mostrecentitemname = llList2String(workingList ,x) - 1;

Does anybody have a technique to find the most recently added item to an inventory, without deleting all old items in the inventory?

(what if they add multiple at the same time,, is that ok?) anyone know the behavior of the changed_inventory when you drag a category of items into the objects inventory? does it spawn the changed event for each item dropped or does it only spawn once?
Dan Medici Registered User Join date: 25 Jan 2004 Posts: 132	11-22-2004 12:46 Oooh, good idea, Strife and Tad. I remembered asking Strife this a while back but I forgot the technique, heh, sorry. That's a good question tad! I'm not sure. Another question: Do I really have to save the "most recent" to a global variable? Once I have the list of the items in order, can't I just do... CODE integer x = llGetListLength(listofitems); // the list that we are keeping track of string mostrecentitemname = llList2String(listofitems,x) - 1; ?
Tad Jensen Script Junkie Join date: 29 May 2004 Posts: 24	11-23-2004 07:41 i was referring to the two list variables needed to do the compare... CODE list origList; // initially set to contents of object then reset each time the compare process is finished list newList; // holds current contents when addition of inventory item already has started list workingList; // list you maintain and add the new items as you get them so that the last list item is always your newest comparefunction() { origList = ["a","c","b"]; newList = ["a","d","b","c"]; //then you would have some compare logic right here to find out that "d" is the item added... workingList = origList + newListItem; // each time this process is run you always need a snapshot of what the inventory looks like prior to adding an inventory item // this is what i was talking about before needing the global variable for origList = newList; } comparefunction(); integer x = llGetListLength(workingList ); // the list that we are keeping track of string mostrecentitemname = llList2String(workingList ,x) - 1; obviously the above is just quick and dirty pseudo code... what you listed will grab the mostrecent value assuming you have already run your compare and populated the list with the new item at the END of the list you are looking at hope that makes sense... hehe
