libRealSpace 0.3.1 — Release notes (from lcos_030_build → fixes_031_build)

Compare: lcos_030_build...fixes_031_build
Date: 2026-02-28

Highlights

• Bumped version to 0.3.1.
• New INI-based configuration support (SimpleIni) + shipped default assets/config.ini.
• Input system improvements: joystick (raw SDL joystick) axis/button bindings + persistent default bindings file.
• Cockpit/HUD & MFD improvements: new radar single-target view, damage MFD page, better targeting indicators, gunsight HUD offset adjustable in debugger.
• Parser robustness & format coverage: IFF lexer bounds fix; additional REAL/MISN chunk handlers.

---

Added

• Config system (SimpleIni)
  • Added src/engine/Config.cpp and src/engine/Config.hpp (singleton wrapper around SimpleIni).
  • vcpkg.json now depends on simpleini.
  • Engine CMake now locates and exposes SimpleIni include dir.
• Default config file
  • Added resources/config.ini, copied into assets at build/install time.
• Joystick support (raw SDL joystick)
  • New input types: JOYSTICK_BUTTON, JOYSTICK_AXIS.
  • Keyboard bindings expanded with bindJoystickButtonToAction / bindJoystickAxisToAction.
  • Debugger controller UI now enumerates joystick axes/buttons dynamically when not using SDL game controller mapping.
• Persistent default bindings
  • GameEngine::initKeyboard() loads default_bindings.cfg if present, otherwise generates bindings and saves them.

---

Changed / Improved

• Window sizing now configurable
  • GameEngine::init() reads Window.width / Window.height from config (with defaults).
  • src/executables/sc/main.cpp loads ./assets/config.ini and applies Window.width/height/fullscreen.
  • Debugger main also loads config (note: it reads Display.Width/Height keys—see “Notes / Potential follow-ups”).
• SDL initialization
  • RSScreen and DebugScreen now initialize SDL with SDL_INIT_JOYSTICK in addition to game controller support.
  • Fullscreen window flags now include SDL_WINDOW_ALLOW_HIGHDPI.
• Rendering
  • SCRenderer::renderWorldToTexture() now renders additional neighboring blocks around block_id (9 renders total).
• Cockpit / HUD / MFD
  • Target projection code refactored into SCCockpit::project_to_screen.
  • HUD target indicator now uses shape assets (TARG->SHAPSET) and displays “in range” marker (MISD->SHAP) when applicable.
  • Added tracking of targetImpactPointWorld and optional debug drawing hooks.
  • Radar mode ASST now uses a dedicated single-target radar rendering implementation that shows only the current target and prints altitude/heading/speed next to it.
  • Added Damage MFD page (RenderMFDSDamage) and integrated it into both 2D and virtual cockpit rendering paths.
  • Camera MFD width calculation fixed (was incorrectly using height).
  • Gunsight HUD angular offset is now adjustable via a new debugger menu panel (“GunSight HUD angular offset”) and used in virtual cockpit.
• Mission / audio behavior
  • SCMission tracks an in_combat flag set when an AI actor targets the player.
  • SCStrike::runFrame() switches music to track 5 during combat, otherwise uses mission tune.
• Target selection
  • SCStrike::findTarget() now:
    • filters enemies within 30,000 units,
    • sorts candidates by distance,
    • cycles to the next target (instead of always snapping to nearest).
• Camera look-at
  • setCameraLookat() now:
    • if target is very far (> 20000), uses plane forward direction instead of target framing,
    • passes an explicit up vector into camera->lookAt(...).
• Palette LUT
  • BuildPaletteLUT() now searches only the green ramp [128..159] (instead of all 0..255) and uses 128 as the starting best index.

---

Fixed

• IFFSaxLexer bounds/size handling
  • If the computed chunk_size + 8 exceeds available buffer at the start of parsing, the code now allocates a larger buffer, copies data, and reinitializes the stream to avoid overrun.
• ByteStream destructor
  • Clears cursor pointer in destructor.
• HUD shape parsing
  • RSHud::parseREAL_CHUD_LARG_TARG_SHAP() now builds an RSImageSet via PakArchive (and assigns SHAPSET) instead of manually LZW-decoding into an RLEShape.
• Removed noisy debug prints
  • RSMapTextureSet texture dump spam removed; palette transparency print removed; some mission parsing prints removed.

---

Format / content parsing coverage

• RSEntity now registers/accepts additional REAL chunk handlers (stubs added):
  • REAL:INFO
  • OBJT/TRCR:INFO
  • MISS/DYNM:{ATMO,GRAV,AGRV}
  • APPR/POLY/TRIS:LNTH
  • OBJT/ORNT:SIGN handler wiring added
• RSMission now registers MISN:CACH (parser stub) and LOAD parsing was cleared out (now empty).

---

Packaging / build system

• Top-level CMakeLists.txt
  • project version 0.3.0 → 0.3.1
  • assets now also copy MID_36.IFF and config.ini.
• vcpkg.json
  • added dependency: simpleini
