Goober5000andClaude Fable 5 d40fcd16c0 fix player subsystem targeting from sexps and scripting
Fix a regression from #7393: `last_targeted_subobject` must be updated when the player's target and target subsystem are changed, or the subsystem will be retargeted due to `hud_target_change_check`.

Also fix related issues:
- the `ship.Target` and `ship.TargetSubsystem` scripting setters now use the standard `set_target_objnum` function and also correctly handle the new target subsystem
- fix an indexing error in `order.TargetSubsystem`

Fabian Woltermann d0cefc87bd Fix inverted scpui icons and 3d ship/weapon select models rendering in the wrong place (#7647)
* Fix Vulkan render target readback orientation to match OpenGL behavior

* Add render target pass resumption after Vulkan shadow rendering

Ensure that Vulkan render targets resume rendering properly after shadow passes, particularly for off-screen targets like SCPUI's 3D previews, to prevent unintended content leakage onto the screen.

* Skip alpha writes for additive batched bitmaps in render targets to preserve coverage and prevent opaque artifacts.

* Add external subpass dependencies to Vulkan render passes to fix read/write hazards

Introduce explicit memory dependencies for color attachments sampled between passes to prevent flickering and graphical artifacts caused by read-after-write and write-after-read hazards.

* Support fractional alpha values in createColor function and preserve 0-255 compatibility

b26b9cf743 Add Vulkan rendering backend, with HDR10 output and raytraced shadows (#7554)
* Shadow overhaul round 2: PCSS, dynamic cascades, cockpit/instanced shadows

Squashed snapshot of lafiel/shadow_overhaul_2's continuation work
(d3922aa87..010f9d2d9), which has no separate upstream PR of its own.

* Add Vulkan rendering backend

Squashed snapshot of the Vulkan backend as vendored into this branch
(ce2d1e85f..6ce539463, authored by Mara van der Laan with build/CI
fixes by Taylor Richards). This work has its own upstream PR #7553
(notimaginative:vulkan-pr-new) and is not otherwise original to true-hdr.

* Add true HDR output, RT shadows, and PCSS shadows for Vulkan

Squashed snapshot of true-hdr's own integration work: true HDR
framebuffer output, wiring the shadow overhaul into the Vulkan
backend (raytraced + cascaded shadow maps), logging refactors, log
filter UI, and CI/build fixes.

* refactor: update Vulkan logging calls to use `nprintf` for scoped logging

* fix: correct shadow cascade count in Vulkan logging calls

* fix: fall back to PATH-resolved ccache when CCACHE_PATH is stale

CI hardcodes /usr/local/bin/ccache, but macOS runners on Apple Silicon
hosts install Homebrew (and ccache) under /opt/homebrew instead,
causing all four Mac configs to fail with "No such file or directory".

* Fix vulkan texture readback to correctly handle transparent pipelines

* Put the pixel swizzles into a util file

* OOB safety check

* Fix fog handling

* Fix MSAA in Vulkan

* fix: enable SMAA for vulkan

* adapt the post-processing AA shaders to hdr

* fix clang-tidy warnings: concatenate nested namespaces, static methods

pixel_swizzle.{h,cpp}: collapse `namespace graphics { namespace util {`
into `namespace graphics::util {` (modernize-concat-nested-namespaces).

VulkanState.h/VulkanDraw.h: getClearColor()/setClearColor() only touch
gr_screen and other globals, no instance state, so make them static
(readability-convert-member-functions-to-static) and drop the
top-level const on getClearColor()'s return type
(readability-const-return-type).

* fix clang-tidy warning

* Extend raytraced shadows to all directional lights

RT shadows previously only shadowed the first directional light in the
scene, even though multi-sun missions push more than one directional
light into the engine. The TLAS raytraced shadows query against is
already light-agnostic, so this extends both the deferred lighting
pass and the forward MODEL shader to shadow every directional light
(capped by a new Max Raytraced Shadow Lights option, configurable via
the in-game Options menu or the Lab's Scene rendering options).

Cascaded shadow maps are untouched: they're built for a single light
only, so the deferred pass still limits itself to one shadowed
directional light whenever CSM (not raytracing) is the active method.

* refactor: improve shader flag handling and render target finalization in Vulkan backend

- Consolidate shader flag setup logic in VulkanPostProcessingLighting to simplify configuration.
- Fix dead field usage in VulkanDraw by ensuring correct image view selection for environment maps.
- Add mip chain regeneration in VulkanRenderer::endRenderTarget to ensure correct mip levels for cubemaps.

* fix: ensure correct mip chain initialization in cubemap rendering

- Add mip chain generation to VulkanDraw for cubemaps with multiple mip levels.
- Fix potential issue with uninitialized mip levels above level 0 in deferred-f.sdr sampling paths.

* fix: don't crash on startup when environment locale is unavailable

std::locale("") pulls in the process's environment locale categories
(LC_CTYPE, LC_MONETARY, LC_PAPER, etc.), and throws std::runtime_error
if any of them names a locale not installed on the host (e.g.
mismatched regional-format overrides). Since SCP_default_locale is
constructed during static initialization, before main() and before any
of our own exception handling exists, an uncaught throw here aborted
the whole process before the game even started. Fall back to the
classic "C" locale instead, which is sufficient since this locale is
only ever used for ASCII case-folding (SCP_toupper/tolower/isdigit).

* Ensure memory flushes after UBO updates and add explicit pipeline barrier for MoltenVK compatibility.

* fix: add clear pass for SMAA edge detection to prevent persistent artifacts

* feat: add Vulkan debug-utils messenger, opt-in sync validation, frame diagnostics

Groundwork for the renderer-review fix series (.agents/plans/
vulkan-renderer-review-fixes.md, Phase 0):

- Register a VK_EXT_debug_utils messenger (preferred) instead of only the
  deprecated VK_EXT_debug_report callback, which is kept as a fallback for
  loaders without debug-utils. The messenger config is also chained into
  instance creation so vkCreateInstance-time messages are captured.
  Validation errors/warnings now go to the main log via mprintf.
- New -gr_sync_validation cmdline flag (implies -gr_debug): chains
  VkValidationFeaturesEXT with synchronization validation into instance
  creation when VK_LAYER_KHRONOS_validation is available. This is the
  regression net for the synchronization fixes in the following commits.
- Frame stats now report descriptor sets/writes allocated per frame and the
  total pipeline count (descriptor-manager counters; DescriptorWriter::flush
  moved out-of-line to report into the manager).

* refactor: unify Vulkan render-pass begins, clamp in-pass clears, add per-frame UBO ring

Phase 1 of the renderer-review fix series: shared helpers that the
correctness fixes build on.

- New VulkanRenderer::beginTrackedRenderPass(PassBeginDesc): every render-pass
  begin on the frame command buffer now records vkCmdBeginRenderPass and
  updates the state tracker (pass, color attachment count, sample count,
  render area, viewport) in one place. Converted: setupFrame,
  beginSceneRendering (both branches), resumeSceneRendering,
  endSceneRendering, beginRenderTarget (viewport kept for gr_set_viewport),
  resumeSwapChainPass, plus new resumeScenePassAfterCopy() shared by
  copyEffectTexture/copySceneDepthForParticles and
  rebeginSwapChainPassAfterReadback() shared by both readbackFramebuffer
  exits (~200 lines of duplicated begin/clear/viewport blocks removed).
- The state tracker records the active render area; all four
  vkCmdClearAttachments sites clamp their rects against it and skip empty
  results. Previously gr_screen-sized clear rects could exceed a smaller
  off-screen render target's render area, which is invalid API usage.
- New PerFrameUboRing utility (VulkanPerFrameUbo.h/.cpp): a persistently
  mapped uniform buffer with one slot region per frame in flight and a
  self-flushing alloc(). Used by the next commit to fix the cross-frame
  UBO races.

Deliberate behavior deltas (all safe-direction): the helper always sets
colorAttachmentCount/sampleCount (some sites previously inherited stale
values), and resumeSwapChainPass/resumeSceneRendering now also reset the
standard flipped viewport instead of leaving the previous one.

* fix: eliminate Vulkan cross-frame UBO/buffer races, make gr_sync honest

Phase 2 of the renderer-review fix series: with two frames in flight, several
host-visible resources were rewritten by the CPU while the previous frame's
GPU work could still be reading them.

- The post-processing scratch UBO is now a PerFrameUboRing (per-frame-in-
  flight slot regions, persistently mapped, self-flushing alloc). All the
  per-pass map/unmap/cursor bookkeeping in bloom/LDR/fog/SMAA is deleted;
  the cursor resets exactly once per frame via the new
  VulkanPostProcessor::beginFrame() hook in setupFrame.
  This also fixes two latent bugs: (a) fog consumed scratch slots mid-scene
  and bloom's later same-frame cursor reset overwrote them before submission
  whenever fog+bloom were both active; (b) volumetric_fog_data (288 bytes)
  overflowed the 256-byte slots - the memcpy spilled into the neighboring
  slot and the shader's bound range ended before the aspect/fov/noise
  fields. Slots are now 512 bytes (static_assert at the fog call site) and
  the per-frame budget is 32 slots.
- The dedicated tonemap, output-encode, and MSAA-resolve UBOs (each a single
  instance rewritten per frame, i.e. racy; the MSAA one also never flushed)
  are deleted entirely - those passes build their structs on the stack and
  allocate from the scratch ring.
- Static-buffer rewrites orphan instead of racing: getVkBuffer() stamps a
  last-used frame number, and a full-content updateBufferData() on a Static
  buffer used within the last MAX_FRAMES_IN_FLIGHT frames defers the old
  VkBuffer to the deletion queue and writes a fresh one. Offset writes
  (GPU-heap appends to fresh regions) and PersistentMapping buffers (the
  engine holds their mapped pointer and syncs via gr_sync) are exempt.
- gr_sync_wait now honors its contract: VulkanRenderFrame::waitForFinish
  takes a timeout and reports expiry without consuming the fence;
  VulkanRenderer::waitForFrame returns false for fences taken during the
  still-recording frame (previously it waited on a stale or idle slot and
  reported success) and resolves the frame->slot mapping correctly. This
  makes UniformBufferManager's segment-fence throttling actually protective
  on Vulkan for the first time.

- Introduced `ModelDrawParams` structure and `computeModelDrawParams` function to unify indexed draw parameters for models and shadows.
- Simplified draw logic by eliminating repeated calculation of indexed draw parameters and improving code reuse.

* Add `releaseAnimationSlotRef` for ref-count handling of shared animation texture arrays

- Introduced `releaseAnimationSlotRef` to manage reference counting for shared animation texture-array slots, preventing premature destruction of shared resources.
- Updated `flushTextures` and related methods to integrate `releaseAnimationSlotRef` for shared slot cleanup.
- Refactored staging buffer creation into `createStagingBuffer` for 3D texture uploads and shared path consistency.
- Enhanced texture upload logic with improved tracking and logging for re-upload cases, aiding preloading gap analysis.

Goober5000 00c8b0f63b Merge pull request #7583 from Goober5000/fix/lua_secondary_bank_fields
fix Lua weapon bank setter writing primary fields for secondary banks
2026-07-10 23:53:17 -04:00
Goober5000andClaude Opus 4.8 bed228d264 avoid undefined behavior from UNREACHABLE on reachable code paths (#7555)
* avoid undefined behavior from UNREACHABLE on reachable code paths

UNREACHABLE expands to __assume(false) / __builtin_unreachable() in
release builds, which is undefined behavior if the code is ever actually
reached. Many UNREACHABLE sites only guard against unexpected-but-
possible runtime states (values from tables, mission/save files, network
packets, scripting, or user input), so reaching them should degrade
gracefully rather than invoke UB.

Replace UNREACHABLE with Assertion(false, ...) at all such sites. It
still pops an error in debug builds, but in release it is a harmless
no-op that simply falls through to the following code. Sites that are
genuinely unreachable by local invariants (e.g. a switch over a bounded
random number) are left as UNREACHABLE.

A few converted sites had no safe fall-through -- an uninitialized read,
null dereference, or null call would have followed -- so they also get a
minimal recovery: initialize the value, guard the dereference, return
early, or skip the offending item.

Where the converted site was a simple guard of the form
    if (x) { Assertion(false, ...); return; }
hoist the check onto the invariant instead:
    Assertion(!x, ...);
    if (x) { return; }
This states the expectation directly and shows the offending value in
the debug popup, while keeping the same graceful runtime degradation.

Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

* addendum

After consultation with Lafiel, use UNREACHABLE in situations that are effectively impossible even if not provably impossible.  UNREACHABLE = "this shouldn't ever happen"; Assertion = "if this ever happens, it's a coding error".  Also fix a few other sites and change a couple to Warnings.

Goober5000 7145b3cb7e Harden Lua matrix and ParticleEffectAction against non-orthonormal inputs (#7490)
Two related fixes flagged by an audit of vm_vector_2_matrix_norm callers:

ParticleEffectAction: locals.direction defaulted to vmd_zero_vector,
which would trip vm_vector_2_matrix_norm's unit-length assertion (and
divide by zero in release) when an action program emitted a particle
effect without first running a Set Direction action.  Default to
vmd_z_vector so the unset-direction path always feeds a unit vector.

matrix_h / Lua orientation type: the element indexer (m[1..9] = x)
wrote arbitrary floats straight into mtx.a1d[idx] and the resulting
non-orthonormal matrix could flow into obj->orient via the Orientation
virt-vars on object/modelinstance/subsystem, breaking downstream engine
code that assumes the basis vectors are unit length.  getInterpolated
had the same problem by design (pure linear interp, no normalization).

Adds a fourth MatrixState, NeedsOrthonormalize, which the indexer
setter and getInterpolated use to flag their output.  ValidateMatrix
and ValidateAngles now call vm_orthogonalize_matrix when they observe
that state, so any consumer that reads through GetMatrix/GetAngles
gets a valid orientation without each call site needing its own guard.

getInterpolated is also marked ADE_FUNC_DEPRECATED at FSO 26.0 in
favor of rotationalInterpolate; mods targeting older versions keep
the legacy linear blend (now safely orthonormalized on use).

* change to new fog system

* Fix fog conversion issues

* remove unused old neb values

* Update scripting API

* temporary old-value round trip

* Rewrite nebula fog with four explicit parameters

Replace the legacy `+Fog Near Mult` / `+Fog Far Mult` model — which
depended on fixed engine constants — with four parameters that map
directly to renderer behavior:

  +Fog 1000m Visibility    fraction of light surviving 1000m of fog
  +Fog Near Distance       meters from camera where fog begins
  +Fog Skybox Clip Distance  max render distance for the skybox in fog
  +Fog Clip Distance       max render distance for the scene in fog

The deferred-lighting fog shader, material system, model renderer,
object sort, and the Lua mission API all consume the new parameters
directly. The legacy `Neb2_fog_near_mult` / `Neb2_fog_far_mult`
globals are removed.

Mission parsing accepts either the legacy keys or the modern keys.
Legacy values are converted to the modern set at parse time, and a
per-mission flag (`Neb2_fog_use_legacy_values`) records which keys to
write back on save. The flag is cleared only when something actually
changes, so opening and OK'ing an unmodified legacy mission preserves
its on-disk format. Saving uses `optional_string_fred` to preserve
user comments through edit cycles.

FRED2 and QtFRED background editors both expose the four parameters
in place of the old multipliers, with friendly labels and tooltips.
Both editors validate input (visibility clamped to [0, 1]; near
distance must be > 0; skybox and scene clip distances may be 0 to
disable fog at that range) and use a snapshot-and-compare at close
time so that a no-op open-then-OK never spuriously rewrites a legacy
mission in the modern format.

FRED2's background dialog is also reorganized so that "Display bg
bitmaps in nebula", "Override nebula fog palette", the RGB row, and
the four fog parameters all sit inside the Nebula group box; the
"Old Nebula" group box is restored below it with its Pattern, Color,
Pitch, Bank, and Heading controls back inside the frame. The dialog
now overrides PreTranslateMessage so that the new fog tooltips —
and the previously broken "Save sun/bitmap angles in correct format"
tooltip — actually fire.

QtFRED's BackgroundEditor.ui adds four QDoubleSpinBox controls in
the existing nebula form layout, with per-field decimals chosen to
avoid scientific notation, and per-field min/max declaring the
validation rules. The QtFRED help page is updated to describe the
new fields.

- Rename Neb2_fog_use_legacy_values to Neb2_fog_save_legacy_values
  to reflect that the flag governs save format, not runtime
  behavior.
- Decide both the save flag and the legacy-to-modern conversion
  purely from whether the file contains modern fog keys, dropping
  the prior heuristic based on required_fso_version. A mission
  without modern keys (legacy- or retail-format) converts on load
  and saves back in legacy format; missions with modern keys are
  saved as modern.
- Snapshot the four fog values as floats at editor open and use
  fl_equal for the no-change comparison in both FRED2 and QtFRED,
  replacing the FRED2 CString comparison and the QtFRED strict
  inequality.
- Document the on-disk invariant in missionsave: when not saving
  legacy keys, the four modern keys must always be written (never
  gated on "only if non-default"), since the parser uses their
  presence to decide whether to run the conversion on next load.

Goober5000 70c4010389 add wing display names (#7429)
* add wing display names

Adds display name capability for wings, matching the pattern and infrastructure of display names for ships.  As in #7234, wing display names take precedence over ship display names, if both are provided; because if ship display names took precedence, a ship would have the same display name in every wave.

All the relevant display locations are handled, including the HUD, escort list, message box, and mission log.  Lua API support is provided as well.

Adds full support for both FRED and QtFRED, including the always-save-display-names setting.

Addresses #7189 and the last request from #1730.

wookieejedi 15e7528d41 Expose new Max Guard Range to scripting (#7451)
Follow-up to #7251, which added `set-guard-range`
This PR exposes that value to scripting, so scripters do not have to use the more expensive `runSEXP` to use it.

The value is initialized as -1 (`max_guard_radius = -1.0f;` line 7913 in ship.cpp), hence the default value for the script is -1.

Goober5000andClaude Opus 4.6 3c6df26da2 remove redundant waypoint position by delegating to the game object
The waypoint class stored its position in m_position separately from the game object's pos field, requiring callers to manually keep both in sync. Now get_pos() and set_pos() delegate to the object position when the game object exists, falling back to the parsed position only if the object does not exist.

3. Tweak `EffectHostTurret` and make sure it works for fighter beams.
4. Prevent `createOnTurret` from running on submodels that are not turrets.

Goober5000 33d5f7ed3c refactor ship anchors
Testing in FotG exposed a bug that dates back to retail.  During mission parsing, arrival and departure anchors were represented by indexes into `Parse_names`.  After parsing, they were converted to ship indexes -- but only in FRED.  Since some functions are shared between FRED and FS2, this can produce inconsistent results, which can be hard to detect since parse indexes and ship indexes are usually the same.

This refactors arrival and departure anchors to be represented by ship registry indexes in all cases.  It also adds conversion functions for the benefit of FRED and QtFRED since those dialogs were designed with ship indexes in mind.

Just as special tokens are replaced in debriefings, replace them in command briefings and briefings as well.

Change `string_replace_tokens_with_keys` to `message_translate_tokens` (since it's the same thing) and add a `replaceContainers` script API function to complement `replaceVariables` and `replaceTokens`.

Also replace every category of token in `sexp_modify_variable` and add comments to places where token replacement might be expected but happens elsewhere.
