Newbie Question: Self-disabling objects.

If I add an object "Thing" to the inventory of another object, but that container already has a "Thing", the new one will be renamed "Thing 1". I know I can write a script that says:

"If this inventory contains a Thing with a number higher than mine, delete me".

However, I may want to keep the old Things around for a while. How can I write a script that says:

"If this inventory contains a Thing with a number higher than mine, don't run any of my scripts".


My container also has a "rezzer" script that will, in response to a chat command, rez a new copy of Thing. It has to explicitly know the name of the object in its inventory. How do I tell it to rez the highest-number "Thing" in the inventory?

I think you may be under the misapprehension that a script A inside an object B within the inventory of another object C can run. When in inventory, an object doesn't do anything, and scripts inside it don't do anything.

One way to identify the highest number Thing is to loop through the names of the objects in the inventory, using llGetInventoryName, in a for loop involving llGetInventoryNumber, and look for the highest number Thing (using something like (integer)llGetSubString(name, 6, -1)) you find.

Without seeing your code I cant comment but I'd add code to the rezzer so it can work out if there is a numbered item. Something like this may work :

string GetLatestRevision(string name)
{
   string result = name;
   integer found = TRUE;
   integer num = 1;
   do
   {
       string newname = name + " " + (string)num;
       integer itemtype = llGetInventoryType(newname); 
       if(INVENTORY_NONE  == itemtype)
       {
              found = false;
       }      
       else
       {
              result = newname;
              ++num;
       }
   }
   while(found);
   return result;
}

I'd be inclined to use an on change event to update a list of the revision numbers to use but again that would be dependant on how you have written your code. Of course if you have a large number of items and revisions it could be very slow.

Thanks for your advice, Newgate. Here's the original Rezzer script that I should have provided already. Note the line "string object1Name = "Object1"". Instead of that, I want it to set object1Name to Thing1, or Thing2, or Thing3, etc, whichever is highest that exists.

So, then, I guess I would replace it with string object1Name = GetLatestRevision(string "Thing" (and, of course, add your code snippet too). Is that right?

Okay.

I'm trying to make a "Fruit Tree" that has five different types of fruit (objects) in its inventory. It also has a rezzing script that will make new copies of the fruit and drop them from the tree. When I make a new version of the RedFruit, I will drop it into the tree's inventory, and it will be automatically named "RedFruit 1".

The rezzing script that I currently have will still operate only on the original RedFruit. The suggestions on this board will help me change the script so that it operates on the highest-numbered RedFruit.

Now here's a new question: the lslWiki script library has a two different scripts which automatically update scripts in child prims. For instance, I can put a new version of a script in my original Fruit Tree, and have it upgrade that script in all the nearby Fruit Trees.

Is there a way to do that with objects? When I put the new version of RedFruit in the original Tree, can I have it appear in all nearby Trees as well?
