osTeleportAgent for hypergrid teleports

[Dot Matrix]

I'm trying to make a single destination HG teleport HUD button by adapting the script from http://opensimulator.org/wiki/OsTeleportAgent -- copied below for completeness. The intention is to make it straightforward for Metaverse Tourists to find their way back to a central spot if they get lost anywhere on the hypergrid.

Code: Select all

// Example osTeleportAgent Script
//
// Set Destination as described below, There are a Few Options depending on Application:
// IN GRID Teleport 
// Destination = "1000,1000"; = Using In-Grid Map XXXX,YYYY coordinates
// Destination = "RegionName"; = Using RegionName
// HyperGrid Teleport (region must be HG Enabled)
// Destination = "TcpIpAddr:Port:RegionName"; = Using the Target/Destination IP Address
// Destination = "DNSname:Port:RegionName"; = Using the Target/Destination DNSname
// Note: RegionName is Optionally Specified to deliver Avatar to specific region in an instance.
// 
// ========================================================================================
// === SET DESTINATION INFO HERE ===
//
string Destination = "LBSA Plaza"; // your target destination here (SEE NEXT LINES) Can Be
vector LandingPoint = <128,128,50>; // X,Y,Z landing point for avatar to arrive at
vector LookAt = <1,1,1>; // which way they look at when arriving
//
default
{
  on_rez(integer start_param)
  {
    llResetScript();
  }
  changed(integer change) // something changed, take action
  {
    if(change & CHANGED_OWNER)
      llResetScript();
    else if (change & 256) // that bit is set during a region restart
      llResetScript();
  }
  state_entry()
  {
    llWhisper(0, "OS Teleportal Active");
  }
  touch_start(integer num_detected) 
  {
    key avatar = llDetectedKey(0);
    llInstantMessage(avatar, "Teleporting you to : "+Destination);
    osTeleportAgent(avatar, Destination, LandingPoint, LookAt); 
  }
}

This script works for in-grid teleports within Kitely, where you just put the region name.

However, it doesn't seem to work for hypergrid teleports, for destinations using "DNSname:Port:RegionName", both within and outside Kitely.

For destinations within Kitely, the message is "Teleport failed. The region "grid.kitely.com:8002:RegionName" could not be found."

For destinations outside Kitely, the message is "Teleport failed. The region you tried to teleport to doesn't exist anymore". However, pasting the external HG address into the map works ("Region found"), so the region does exist.

What am I doing wrong?

This dumps you in the sea at Romenna.

Code: Select all

default
{
    touch_start(integer n)
    {
        osTeleportAgent(llDetectedKey(0),"www.pmgrid.org:8002:rom31",<248,140,27>,<0,0,0>); 
    }
}

Mind you, a fair few cross-grid teleports failed for some reason.

This worked within Kitely but I wasn't able to check other grids.

Code: Select all

default
{
    touch_start(integer n)
    {
        osTeleportAgent(llDetectedKey(0),"Micrographia",<239,208,22>,<0,0,0>); 
    }
}

Thanks, Graham.

I've just tried the first script, as given, from Vespers, which is HG enabled.

The first time I clicked the prim I get an error message that "The destination region doesn't exist anymore."

The second time I clicked it, the teleport worked. Hurray!

But why don't things work every time?!

Edited to add... what an impressive destination!

Yes, Romenna is a great place to visit but historically has always suffered performance-wise. A great place to take a friend but not a safari.

As an alternative method for getting people to the same spot, I've been trying

Code: Select all

    default
    {
        touch_start(integer n)
        {
            llMapDestination("www.pmgrid.org:8002:rom31",<248,140,27>,<0,0,0>);
        }
    }

Providing the position is in the SW area of a varregion (i.e. x and y are less than 256), this method works. Unfortunately, I'm trying to get people to the NE area.

I don't know why, but I can confirm that HG travel attempts often result in that message. My blog is carrying the advice to ignore that message on the first try. Most of the time it works on the second try. My guess is that the time-out is set too soon and does not allow enough time for the timeout to complete unless the database is already accessed.

Thanks, Selby!

A further test using llMapDestination suggests that focusing on a single region rather than part of a varregion is helpful.

And using the original script with a single region also works.

/me scratches head.

Testing the HUD with Daniel Hoffman's help, I made another discovery. Using the HUD with osTeleportAgent does not work if you are not on your own land (to do with threat level). So it looks like I need to use llMapDestination in a general-purpose HUD.
