2026 week #31: SUG Leviathan Hour: game_control / region crossings

The following notes were taken from the Tuesday, July 28, 2026 Simulator User Group (SUG) off-week meeting (the “Leviathan Office Hour”). These notes form a summary of the items discussed, and are not intended to be a full transcript. They were taken from my chat log of the meeting, and Pantera’s video is embedded at the end of this article – my thanks to her, as always, for recording 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 is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
• The “Leviathan Office Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
• Meetings are held in text in-world, at this location.

Game_Control

• Leviathan has cut a new version of the game_control viewer (v0.7.8). This includes:
  • Per-axis per-mode invert option.
  • Keyboard support for flycamming.
  • Variable speed for avatar rotations when using the game controller stick.
  • Mouse-click actions for Mouselook mode.
  • Mouse mode (ability to control the on-screen with a gamepad.
• His hope remains to get the game_control capabilities into the Lua editor viewer before that finally goes to release status (which might happen in the latter part of August).
• However, internal discussions at the Lab have caused Leviathan to realise he needs to overhaul the GameControlInput UDP message format server-side before the code can go out in a viewer. This work will also require a server-side code updates for the simulator in order for game_control to work.

Region Crossings

• During the week #30 Simulator User Group meeting, Pepper Linden indicated he had put together some fixes to address vehicular region crossings.
• Those updates have no been deployed to the Blake Sea region on Aditi (the Beta grid) for those wishing to test them.
• Sandbox Wanderton and its neighbours are also going to be cloned on Aditi for further vehicle testing on land.
• The above work is separate to Harold Linden’s work on script serialisation to prevent scripts from crashing/disabling on a region crossing should be live across the grid in the current simulator release.
• He also indicated LL is aware of recent region crossing issues within Blake Sea on Agni (the Main grid), which might be griefer related.

In Brief

Please refer to the video for more on the following.

• As per my week #29 Leviathan Office Hour notes, PromptFont is being used for the game_control preferences UI.
  • It was asked if the tool could be more widely used within the viewer.
  • However, there are no plans to do so because the version in use has been modified for that specific use, with a large number of unused glyphs stripped out that to reduce viewer installer bloat and limit dependency on PromptFont beyond the game_control requirement.
  • The above sparked a conversation on viewer fonts that ran through most of the meeting.
• A general discussion on the use of AI LLMs for coding.

Date of Next Meetings

• Formal SUG meeting: Tuesday, August 4, 2026.
• Leviathan Linden: Tuesday, August 11, 2026.
