Summary

Function: key llRequestInventoryData( string name );

Requests data about the item name in the prim's inventory. When data is available the dataserver event will be raised.
Returns the handle (a key) that is used to identify the dataserver event when it is raised.

• string name an item in the inventory of the prim this script is in
name's Inventory Type dataserver Description
Landmark (vector) The vector data received by dataserver is an offset from <0,0,0> of the current region. To obtain the global position of a landmark add llGetRegionCorner().

Caveats

  • This function causes the script to sleep for 1.0 seconds.
  • If name is missing from the prim's inventory then an error is shouted on DEBUG_CHANNEL.
  • The description of the vector returned in the dataserver event above implies the value is a region coordinate; it in fact represents the distance in meters of the landmark's location relative to <0,0,0> in the region in which the script is running. For a landmark pointing to a location in the current region, that's the same as a region coordinate; however, when used with a landmark pointing to a different region the vector's x and y values can be quite large (and/or negative). The vector is suitable for use in calculating a global coordinate (as above) or a landmark's distance from the object containing the script in the current region or across the entire Second Life grid.
