Wiki description

Requests data about the item name in the prim's inventory. When data is available the dataserver event will be raised.

Specification

name's Inventory Type		dataserver	Description
Landmark		(vector)	The vector data received by dataserver is a global position as an offset from the current region's origin (<0,0,0>). To obtain the absolute global position of a landmark, add llGetRegionCorner() to the vector.

Caveats

• This function only returns data for landmark items in inventory. Other item types are not supported.
• The vector returned from landmarks is 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.

Examples

//-- Open map for owner to 1st landmark in object inventory on touch
//-- *MUST* be in an attached object (llMapDestination Requirement for non-touch use)
key vgKeyOwner;

default

  touch_start( integer vIntNull )
  {
    if (llDetectedKey( 0 ) == vgKeyOwner)
    {
      integer vIntLMcount = llGetInventoryNumber( INVENTORY_LANDMARK );
       //-- make sure we have a landmark in invetory
      if (vIntLMcount)
      {
        llRequestInventoryData( llGetInventoryName( INVENTORY_LANDMARK, 0 ) );
      }
    }
  }

  dataserver( key vKeyNull, string vStrData )
  {
     //-- because we don't know who touched us in this event, this
     //-- only works for the owner when called from the dataserver
    llMapDestination( llGetRegionName(), (vector)vStrData, ZERO_VECTOR );
  }

  on_rez( integer vIntNull )
  {
    llResetScript();

//An easily-configurable teleporter that sets its destination by getting it from a landmark in the prim's inventory
//Note: this teleporter is subject to the 300m distance limit for llSitTarget
//by Ilse Mannonen

//on state entry, request inventory data and set text for first landmark found in inventory.  
//If none, complain
//on getting data, set sit target
//on change in inventory, reset script
//on sit, TP the person and unsit

//Thanks to Pol Tabla, who wrote the simple sit-teleport script I have adapted here

        if (change & CHANGED_INVENTORY)
        {
