The following notes were taken from the Tuesday, July 2nd, 2024 Simulator User Group (SUG) meeting. They form a summary of the items discussed, and are not intended to be a full transcript, and were taken from my chat log and the video by Pantera – my thanks to her as always for 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):
- Every Tuesday at 12:00 noon SLT.
- In text (no Voice)
- At this location.
- Meetings 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
- No deployments for the week, but all channels will be restart per usual schedule.
Coming up as the next simulator update is Summer Fun, which is currently with the Lab’s QA team. Following that will be Picnic, which among other things will include the following LSL functions:
- llFindNotecardText
- llFindNotecardTextSync)
SL Viewer Updates
The webRTC RC viewer updated to version 7.1.9.9688089989 on July 1st, 2024.
The rest of the current official viewers remain as:
- Release viewer: version 7.1.8.9375512768, formerly the Graphics Featurettes RC viewer dated June 5 and promoted June 10th.
- Release channel cohorts:
- Atlasaurus RC (object take options; improved MOAP URL handling), version 7.1.9.9620320242, June 27.
- Maintenance B RC (usability updates / imposter changes) 7.1.9.9555137545, June 21.
- Maintenance C RC (reset skeleton in all viewers), version 7.1.9.9469671545, June 14.
Luau Projects
These note are related to the Product and Engineering Town Hall at SL21B,when it was announced Luau VM is to be implemented on the server-side, eventually replacing Mono VM.
- Signal Linden is putting together a technical FAQ about lua with has more detailed answers about “why lua and not [insert option]” and “how is lua faster than mono” etc.
- Pepper and Rider Linden confirmed part of the work planned will allow for shadow execution of scripts under the Luau and Mono VMs during testing, which will ensure that all output of functions are the same.
- This shadowing will likely be only be visible to the Lab.
- Once LL is convinced both behave the same, the switch to using the Luau VM. At that point, the anticipated memory and execution time improvements should become visible.
- Finally LL will allow a switch to compile either LSL2 or Luau.
- Signal further indicated:
- That with the switch to lauau on the back-end, code can be written in either LSL2 or Luau.
- That both the current Lua client-side project and the announced luau back-end work, whilst separate projects will both leverage Luau, not Lau.
- Pepper Linden confirmed LSL functions will continue to be maintained, but using Lua will allow for the creation of versioned functions for Lua scripts, providing a more flexible means to update functions without the worry of breaking content.
- This discussion took up most of the meeting – please refer to the video for more.
In Brief
Please refer to the video for the following and other topics discussed:
- Leviathan Linden is hoping to provide an updated GameControl viewer download. It will contain no additional capabilities, but will be updated to the current viewer development branch. However, GameControl will now be behind a single UI setting which will need to be set in order to see its UI.
- Monty Linden confirmed that the first batch of teleports / region crossings work will now likely surface in the Picnics simulator update.
