v1.7.5

[Kaffeine]

Mostly a bugfix and maintenance release: the game moved to SDL3, gained a native MSVC build, and
had its renderer rebuilt underneath.

• Ground camera height (z position) now always saved/restored on view save/restore
• Following camera now persists when switching camera type (Ground <-> Zenith)
• A number of pathfinding improvements (performance and responsiveness)
• Screenshot capture is now more robust, and the 'Paused' overlay is no longer included
• Screenshot of a menu holds just the menu instead of the black border around it
• Optimized the game startup
• Added models, cursors, and planet minimaps texture modding support
• Added support for scaled planet maps
• Added a console (press Ctrl+Alt+Shift+F11 and type console on there)
• Added initial implementation of crash dump with hangs detection (reports saved to logs/)
• Screenshots now go into a screenshots directory instead of the game's own data
• PNG textures are now preferred over the original formats and can be overridden by mods
• Display options are now Window Mode (Exclusive Fullscreen / Borderless Fullscreen /
  Windowed), Resolution and Refresh Rate as separate settings, instead of one long list
• Reworked first person aiming to behave the same whatever the frame rate and resolution
• Music now crossfades between the menu and gameplay tracks, and each resumes where it
  left off instead of restarting from the beginning on every switch
• The starfield now twinkles, and star colours and sizes follow the star's brightness
• FPS counter (Ctrl+Shift+F7) is now available in release builds
• Enter now sends a chat message to all players, F2/F3/F4 address a target and
  toggle alliances
• Text fields now support word jump and word deletion with Ctrl, and Ctrl+V paste
• The game version is now carried in LAN discovery and checked when joining. A client
  with a mismatched version is now told so, along with both versions.
• Joining a session no longer blocks the game while it waits for the host
• Removed the 'Screen resolution lock' option
• Removed the Gamma correction option, which SDL3 no longer supports
• Fixed constructions interiors not being race specific (always red)
• Fixed machines moving forth and back in corridors (e.g. in 'Regain Control' mission)
• Fixed many cases where machines could get stuck and lock each other
• Fixed camera move and zoom at the same time (basically reimplemented zoom with mouse wheel)
• Fixed selection marker rendering (2D/3D and runtime switching)
• Fixed rendering/culling issues that could cause missing world tiles / rooms not being rendered
• Fixed nearest Mine and Smelter/Pod lookup for Transporters / resource carriers
• Fixed nearest Lab lookup for Technicians
• Fixed a destroyed machine carrying on with its update while teleporting in or out
• Fixed a crash when a Resource Carrier was sent to a mine it could not reach
• Fixed crash on close by Alt+F4
• Fixed a crash on choosing an entry from a drop down list
• Fixed the audio stuttering during video playback
• Fixed the anti-aliasing option not being applied
• Fixed the drawing of rectangles and lines
• Fixed a number of issues with 2x interface scale
• Fixed the game menus opening while a modifier key was held
• Fixed multiplayer chat messages being truncated
• Fixed the port byte order in LAN discovery packets
• Fixed a double ENet shutdown
• Fixed sprite animations (fires, explosions, and the like) running at the frame rate
  rather than at the speed of the game
• A few more small fixes

Also, check the available mods: wiki/Mods#known-mods

Still the same... pressing the 'Initiative' button (of course, not every time) — OpenGL not responding.

An issue in audio subsystem (audio player can't create ID for the next sample of sound). I'll take a look.

[Kaffeine]

I see how this particular "Initiative" button is different from the others: it plays two sounds instead of one, and it is the button you'd click many times, which can exhaust the pool of audio channels.

I can't reproduce the issue locally but the problem is visible: the game used (valid) channel=0 index for "no more channels available", which led to mismatch of unused channels number, eventually degraded to a loop "I know there is an unused channel, so let's try to find it again".

Fixed in build https://github.com/WiredForWar/machines/actions/runs/33789512800 (file machines-win64-wfw-20260903.7z).

I'm yet to decide when release v1.7.6; probably I'd wait a few more days for feedback to address more bugs at once. You can use the linked builds for now. It has two more issues fixed:

• shadows on screenshot could get wrong color if alpha-channel supported by the window surface
• shutdown could be delayed by up to 2.5 s.

[FightingForFun]

Thank you for your work.

I'm already using the version machines-win64-wfw-20260903.7z

1 - I press PrintScreen in the game itself (just in case, I also tried FN+PrintScreen – but that didn't work either)... and nothing happens, no screenshot is taken, and no folder is created in the game's root directory either.

2 - I played through one scenario and completed it. Then I chose the Graco scenario, and the game crashed to the desktop with no error message.

3 - A small enemy unit drove into the research building (it had been chasing my researchers) and now it's just standing there, doing nothing. First time I've ever seen one enter a building, but since it did, it should be attacking. Instead, it just stays there – not attacking, not leaving.

4 - Graco scenario: Wrong camera position.
By default, it's currently set like this:

But it should be like this. In other maps, that's exactly how it is:

PS: All this isn't really that important. The main thing is that there were no crashes in the game itself (during the scenario, in the middle or at the end of an epic battle).
