Summary

Function: llTeleportAgentGlobalCoords( key agent, vector global_coordinates, vector region_coordinates, vector look_at );

Teleports an agent to set of a region_coordinates within a region at the specified global_coordinates. The agent lands facing the position defined by look_at local coordinates. A region's global coordinates can be retrieved using llRequestSimulatorData(region_name, DATA_SIM_POS)

• key agent avatar UUID that is in the same region (avatar to be teleported)
• vector global_coordinates Global coordinates of the destination region. Can be retrieved by using llRequestSimulatorData(region_name, DATA_SIM_POS).
• vector region_coordinates Destination position inside the target region, given in local coordinates.
• vector look_at Location avatar will face after completing the teleport, given in local coordinates.

To run this function the script must request the PERMISSION_TELEPORT permission with llRequestPermissions and it must be granted by agent. The combination of llRequestSimulatorData and llTeleportAgentGlobalCoords allows agents to be teleported to regions by region name.

Caveats

Permissions
  • Once the PERMISSION_TELEPORT permission is granted there is no way to revoke it except from inside the script (for example, with a new llRequestPermissions call) or the script is reset or deleted.
  • This function cannot be used in a script in an object attached using llAttachToAvatarTemp.
  • This function can only teleport the owner of the object.
  • Sitting avatars cannot be teleported using this function. You must llUnSit them first.
  • This function will cause other HUD scripts worn by the same user (or other scripts in the same HUD) to crash unpredictably, resulting in "Unable to load script state" and "Bounds check Errors", see #BUG-4062.

Examples

<lsl> string simName = "Help Island Public"; vector simGlobalCoords;

vector landingPoint = <128.0, 128.0, 24.0>;

key owner;


default {

   on_rez(integer start_param)
   {
       llResetScript();
   }
   changed(integer change)
   {
       if (change & CHANGED_OWNER)
           llResetScript();
   }
   state_entry()
   {
       owner = llGetOwner();
       llRequestPermissions(owner, PERMISSION_TELEPORT);
       llRequestSimulatorData(simName, DATA_SIM_POS);
   }
   touch_start(integer total_number)
   {
       key id = llDetectedKey(0);
       if (id == owner)
       {
           if (simGlobalCoords == ZERO_VECTOR)
           {
               llOwnerSay("Config error, tp request was denied. Please try again!");
               llResetScript();
           }
           else
           {
               llOwnerSay("Teleporting you to: http://maps.secondlife.com/secondlife/"
                   + llEscapeURL(simName) + "/" + (string)llRound(landingPoint.x)
                   + "/" + (string)llRound(landingPoint.y) + "/" + (string)llRound(landingPoint.z) + "/");
               llTeleportAgentGlobalCoords(owner, simGlobalCoords, landingPoint, ZERO_VECTOR);
           }
       }
       else
       {
           // llRegionSayTo is faster than llInstantMessage and we can assume
           // that the touching avatar is within the same sim
           llRegionSayTo(id, PUBLIC_CHANNEL,
               "Sorry, I can't tp you. You're NOT my owner!");
       }
   }
   run_time_permissions(integer perm)
   {
       // if permission request has been denied (read ! as not)
       if (!(perm & PERMISSION_TELEPORT))
       {
           llOwnerSay("I need permissions to teleport you!");
           llRequestPermissions(owner, PERMISSION_TELEPORT);
       }
   }

// dataserver event only called if data is returned // or in other words, if you request data for a sim that does // not exist this event will NOT be called

   dataserver(key query_id, string data)
   {
       simGlobalCoords = (vector)data;
       // llOwnerSay("Sim global coords: " + (string)simGlobalCoords);
   }

}
