News for October 22, 2026

Commit 038c27 on main handles 0-byte model files that were crashing the game; commit 75a5a6 gets Linux32 building again for now.

evilpigeonlol reported that save and map transitions crash with an empty save file on x86-64 (Windows). In #next-update, Ormi asked the same.

In #lua-help, DoctorHugoSource asked about a new error in an unchanged mod; Redox identified an infinite loop and explained that SetPos now triggers Touch, which calls SetPos again, after the change "Make Entity:SetPos run trigger touch events".

BREEDNKMs asked for m_hGoalEnt for GOALTYPE_PATHCORNER navigation. Closed on 23 October; commit 7b6a89 allows it.

In #next-update, Vitroze reported that after Alt+F4 → Cancel, opening the Problems menu and clicking outside loses focus on the main menu (x86-64 build 10211). Dezlo saw server-created menus not removing properly after cancelling the prompt. Earlier, Drago🐉 noted that closing GMod via Alt+F4 or the taskbar now brings up a confirmation menu.

In #next-update, Evgeny Akabenko reported a crash on map load after the x86-64 update (CUtlBuffer::PeekGet invalid offset 0), caused by an addon with 0-byte model files left by a download that ran out of disk space.

Rubat asked Artemking4 for code that reproduces the problem.

In #next-update, Redox reported servers where cache/map_pack.bsp stops updating, so new maps load lumps from previous ones until a restart. Rubat said it must be written to disk and may need more error handling, and listed the related log messages. They have to be searched for in console.log with -condebug, which Redox avoids for performance; Cynthia suggested enginespew.

In #next-update, Redox (22 Oct) and Nykez (23 Oct) saw bad argument #1 to 'DrawPoly' (table must contain at least three vertices), for example from cl_arc.lua. On 25 Oct Vitroze asked whether it would be fixed. Nykez said it is a bug fix and code has to be fixed, and Rubat agreed: "its not valid code on your end". Beelzebub posted a one-line patch for the bad math in luabee's arc library.

In #next-update, Redox asked why x86-64 still gets updates when it looks like it'll be deleted in weeks or months. Rubat: "for more wide testing, yeah". Redox suggested an announcement telling people to switch from x86-64 to dev.

Commit bb0975 on the x86-64 beta brings over the main changes from 5–12 October: the surface.DrawPoly error on fewer than 3 vertices, the mcore rope fix, ALT+F4 closing the game, the getmetatable() LuaJIT fix, the map compiler updates, Entity:SetPos running trigger touch events, menu state library removal, the HQ Eli face and the other fixes listed in commits 185851, efb205, 7be067, 71ca28, c18cba and 693484.

Badger9 confirmed tex2Dlod returns 0 in vs_3_0 shaders and asked for $vertextexture0 support, for things like deformable snow and water ripples.

In #developer-talk, Nak showed 5 maps rendered at 187 FPS with his pocket map script, saying baking static meshes helps performance a lot. Later he said he'd combine his RTS base with the pocket map script.

Cheatoid posted a snippet crashing x64 with mcore. robotboy655 couldn't reproduce; Cheatoid then concluded it's a race condition.

In #lua-help, Bloodmasked asked how to disable sv_sticktoground only for some players, such as above a certain speed. Cynthia pointed to the open request for it and otherwise suggested living with it off.

In #developer-talk, nighty said he might release two tools he "purely vibe coded": an opinionated linter/formatter for GMod Lua and a documentation page generator modeled on hexdocs. They process a 1000-file codebase in under 100 ms on his machine.

Be1zebub's Helix PR #464 saves collision bounds and group, name, health and network vars and adds HelixPersistSave/HelixPersistLoad hooks. Opened December 2024; automated review on 22 Oct.

In #lua-help, CreativeGuy asked whether networkVars are saved for persistent props; they seemed to save in his singleplayer test. Beelzebub answered "afaik yes".
