Posted on by Inara Pey
Elvion, January 2024 – blog post †

The following notes were taken from the Tuesday, February 13th, 2024 Simulator User Group (SUG) meeting. They form a summary of the items discussed, and are not intended to be a full transcript. A video of the meeting is embedded at the end of this summary, my thanks as always to Pantera for recording the meeting and providing it.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Simulator Deployments

Upcoming Simulator Release

The simulator update that will be following Gingerbread will be Hearts & Flowers (probably named for the time of year!). This mostly comprises internal (non-user visible) updates, together with two notably user-visible additions:

  • llSetLinkSitFlags/llGetLinkSitFlags – allow you to adjust the sit flags for a prim. It supports the existing two SIT_FLAG_ALLOW_UNSIT and SCRIPT_ONLY.
    • At some future point, SIT_FLAG_HIDE_AVATAR should also be added, so you don’t need to play an animation that squishes the avatar so they aren’t visible in something like a very small vehicle.
  • A feature for estate managers that will allow them to schedule automatic region restarts.
  • A new constant in llSPP PRIM_SIT_FLAGS it will contain all the sit flag information, (including ALLOW_UNSIT and SCRIPTED_ONLY (the two older constants will still be available).

Viewer Updates

The Maintenance Y RC viewer (My Outfits folder improvements; ability to remove entries from landmark history) updated to version 6.6.17.6935642049 on February 9th.

The rest of the official viewers in the pipeline remain as:

  • Release viewer: version 7.1.2.7215179142, formerly the glTF PBR Materials Maintenance RC, issued December 15, promoted January 8, 2024 – numerous bug fixes and improvements – No Change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • Maintenance-W RC viewer, version 7.1.3.7701974306, January 31, 2024 – bug and crash fixes.

Reminders

Jira End-of-Road

LUA Viewer-Side Scripting

  • On Friday, February 9th, Linden Lab announced an upcoming capability: viewer-side scripting using the Lua scripting language – see Coming soon: client-side scripting with Lua!. Possible areas of use for this capability are test automation, mods/plugins, and potentially supporting things like HUDs.
  • There is a pre-release viewer with the Lua support available on github, but there is little more that the team responsible for Lua is willing to say for the present.

Game Controller Update

  • Leviathan Linden has tweaked the game_control capability so that negated the forward/back directions of the stick axes to align more correctly with local-frame coordinates in SL. Pushing forward is now positive rather than negative.
  • He has also disabled game controller support through the old system (Me Menu –> Preferences Option –> Move & View tab –> Other Devices Button –>) – however, this does not impact 3D SpaceNavigator devices.
  • An updated version of the viewer with the game controller capabilities is now available on Github.

In Brief

  • The meeting quickly turned in part to a further discussion on combat, some of which has already been covered in my summary of the first Combat (Committee) User Group in relation to damage, plus a discussion on cheating using offset, etc. – see that summary for the former and the video below for the latter.
  • The above morphed into a general discussion on making water in SL (Linden and user-defined) as “properly” swimmable (e.g. with natural floating / not zooming into the sky and flying when reaching the water / air boundary, etc.) without the need for scripting  / HUDs, etc.
  • A discussion about raycast results, and making it possible for them to get the texture cords for the area where the ray hit the surface of a face, with the result given in a similar manner to detectedtouchST. A canny feature request was asked for, so that LL can look at the idea.
  • There are reports from some of an uptick in HTTP 499 errors with in-world services communication with external services. Those with specific details of these errors are asked to contact Monty Linden.
