llGetInventoryKey

Summary

1/2 Bugs

Function: key llGetInventoryKey( string name );

175	Function ID
0.0	Forced Delay
10.0	Energy

Returns a key that is the UUID of the inventory name

• string

name

–

an item in the inventory of the prim this script is in

If item is not copy, mod, trans then the return is NULL_KEY.
Use llGetInventoryType instead of this function to verify the existence of inventory.

Caveats

• If name is missing from the prim's inventory then an error is shouted on DEBUG_CHANNEL.
• New empty notecards will return NULL_KEY^[1]. Edit and save them to work around this.

A

llGetInventoryKey() returns NULL_KEY when referencing a notecard that is empty

Examples

<lsl>string item = "Default";

default {

   state_entry()
   {
       llOwnerSay("Touch to get information about \"" + item + "\".");
   }

   touch_start(integer total_number)

           INVENTORY_TEXTURE, INVENTORY_SOUND, INVENTORY_LANDMARK, INVENTORY_CLOTHING, 
           INVENTORY_OBJECT, INVENTORY_NOTECARD, INVENTORY_SCRIPT, INVENTORY_BODYPART, 
           INVENTORY_ANIMATION, INVENTORY_GESTURE], [type]);
       string name = llList2String(["does not exist", 
           "texture", "sound", "landmark", "clothing",
           "object", "notecard", "script", "body part",
           "animation", "gesture"], index);

       llOwnerSay("Type: " + name);
       
       if(type == INVENTORY_NONE)
           return;
       
       integer owner_perms = llGetInventoryPermMask(item, MASK_OWNER);
       list perms;
       if(owner_perms & PERM_COPY)
           perms += "Copy";
       
       if(owner_perms & PERM_MODIFY)
           perms += "Modify";
       
       if(owner_perms & PERM_TRANSFER)
           perms += "Transfer";

       if(owner_perms & PERM_MOVE)
           perms += "Move";
       
       llOwnerSay("Perms: " + llList2CSV(perms));
       

integer temp = PERM_COPY

Notes

The UUID returned is that of the asset to which the inventory item points, it is not the UUID of the inventory item itself. The assets themselves are immutable (they never change, they are only ever created and deleted); this allows multiple inventory handles to refer to the same asset without having to duplicate the asset. When it appears an asset is being modified, it is saved as a new asset. The consequence of this is that multiple copies of items in inventory all share the same asset UUID.

Functions

•	llGetInventoryName	–	Returns the inventory item's name
•	llGetInventoryType	–	Tests to see if an inventory item exists and returns its type

•	llGetInventoryCreator	–	Returns the inventory item's creator

Deep Notes

History

• 0.2 - Introduced during the closed beta period.
• 1.2 - Restricted to full perm inventory items only.
• 1.24 - Objects and scripts no longer return their actual UUID but a hash (i.e. pseudo UUID which is consistent with the object/script) instead. -- SVC-3670

Footnotes

1. ^ This happens because new notecards (as inventory items) do not have an attached asset, strictly speaking they do not exist until modified (and saved).
