WhoAddedWhat

To enable you to tell what has been added to a script on CHANGED_ALLOWED_DROP events you can use the following code:

<lsl>list content[]; // a list of all items already added to the object

if (change & CHANGED_ALLOWED_DROP || CHANGED_INVENTORY) {

           integer n = llGetInventoryNumber(INVENTORY_ALL);            

           while(n)
           {
               integer valid = llGetListLength(contents);
               if(valid != 0)
               {
                   string added = llGetInventoryName(INVENTORY_ALL, --n);
                   integer index = llListFindList(contents, [added]);
                   if(!(~index))
                   {
                       if(type != 10 && (string)type != "") // don't add the object's script to the list of items!
                       {

content += added; // add the new item to the checklist of inventory items

                       }

}

               }
           }

}</lsl>
