feat(graphics): implement tactical air unit ground indicator and selection picking - #373
Conversation
…ction picking - Add C&C3/RA3-style tactical ground projection reticle directly beneath airborne units (KINDOF_AIRCRAFT) at altitude >= 15 units - Dynamically blend opacity based on aircraft altitude above terrain, unit selection status, and team/player color - Implement fallback in W3DView::pickDrawable allowing direct selection of airborne units by clicking their ground indicator footprint - Add AirUnitGroundIndicator setting in OptionPreferences and GameData.ini (default TRUE) - Ensure 1:1 cross-platform and base game parity across GeneralsMD and Generals - Update worklog in docs/WORKLOG/2026-10-DIARY.md

Explanation
The title follows Conventional Commits format with the valid type
feat, the scopegraphics, and a clear description of the main ground-indicator and selection-picking changes. It does not contain the@symbol.
Full details: Platform Isolation
-
Explanation
PASS. The added game-logic code in
Core/GameEngine,Generals/Code/GameEngine, andGeneralsMD/Code/GameEngineonly adds preference/configuration fields and calls the cross-platformLocalFileSystem::setAssetRootPath()abstraction. The direct platform changes are confined toCore/GameEngineDeviceand SDL device implementations. The existingunistd.h,readlink, and related platform code in changed game-logic files is unchanged by this pull request. No new Win32, Cocoa, or raw POSIX API leaks into game logic.
Full details: Cross-Platform Determinism
-
Explanation
PASS. The pull request adds no simulation trigonometry or power math that bypasses WWMath. The new indicator code uses fixed scalar arithmetic and squared-distance comparison. The only added division uses the nonzero constant
BLEND_AIR_GROUND_INDICATOR_HEIGHT; its result is validated withWWMath::Is_Valid_Float, andrawOpacityis validated before theIntcast. The SDL frame-duration division and cast are unchanged existing code.
Full details: Openal / Miniaudio Parity
-
Explanation
PASS: The pull request changes no OpenAL or MiniAudio source, header, build, or configuration files. The authoritative diff contains graphics, preferences, filesystem, cursor, deployment, and documentation changes only. Therefore, no OpenAL audio modification requires a mirrored MiniAudio change.
Full details: Conventional Commit Standards
-
Explanation
All 10 subjects in the reviewed range use Conventional Commit syntax and contain no '@'. The
merge: incorporate custom cursors fix into feat/air-unit-ground-indicatorcommit has two parents, so it is a standard merge commit and is explicitly allowed.
Full details: No Hardcoded Local Paths / Sensitive Info
-
Explanation
No hardcoded personal paths, private environment variables, internal URLs, or workspace paths were introduced. The added macOS fallback uses the standard
${HOME}variable (deploy-macos-generals.sh:122-131,deploy-macos-zh.sh:172-181). Other paths use runtime variables such asCNC_GENERALS_PATH,CNC_GENERALS_ZH_PATH,PROJECT_ROOT,RUNTIME_DIR, andSCRIPT_DIR. Added-line inspection found no/Users/...,/home/..., drive-letter paths, credentials, or URLs.
Full details: Ngmp Protocol Integrity
-
Explanation
NGMP protocol integrity is preserved. The reviewed range changes only graphics, preferences, filesystem/cursor handling, deployment scripts, and documentation. No files under GeneralsOnline, NextGenMP, or cmake/ngmp.cmake changed. NGMP UI entry points, loading-screen ticking, NextGenTransport, and MainMenu files are also unchanged. The diff adds no GameSpy replacement, Win32 networking API, WebSocket routing, REST, heartbeat, or thread-safety changes.

Propagate the resolved primary asset directory to TheLocalFileSystem in BIGFileSystem::init so loose files such as Data/Cursors/*.ani can be resolved when runtime cwd differs from the asset root. Make ANI cursor loading, first-frame hotspot extraction, bounds clamping, and static color cursor fallback cross-platform in SDL3Mouse for both Zero Hour and base Generals. Symlink Data/Cursors during macOS deployment and add diagnostic logging for asset fallback and cursor initialization.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winAlign the no-shadow fallback used by rendering and picking.
W3DModelDraw::updateAirGroundIndicator()sizes the decal fromsphere.Radius * 1.5fwhen both template shadow dimensions are unset.W3DView::pickDrawable()instead uses a fixed50.0ffallback. After the shared0.80fscale, the picker always tests a 40-unit footprint, while the decal footprint ismax(1.2 * sphere.Radius, 20.0f). An eligible aircraft with a bounding-sphere radius above or below the matching threshold can therefore have clicks rejected inside its visible decal or accepted outside it.Use one shared fallback-size calculation for both paths. The existing selection fallback contract requires clicks within the indicator terrain footprint to select the aircraft.

Update cursor symlink creation in deploy-macos-generals.sh and deploy-macos-zh.sh to refresh existing symlinks (-L) or create if not exists (! -e). Preserves user-managed directories while guaranteeing redeployment updates symlinks when asset roots change. Update worklog diary.

Context & Motivation
Following the introduction of realistic directional sun-projected shadows (PR #365), airborne unit shadows are projected onto the terrain ~200+ world units away from their physical 2D$(X,Y)$ ground coordinates depending on altitude and sun angle.
In retail C&C: Generals and Zero Hour, aircraft shadows were static vertical 2D decals positioned directly beneath each aircraft. Players historically relied heavily on this vertical shadow as a visual reference to:
With realistic shadows, players frequently missed ground-targeted powers and struggled to select flying units.
Additionally, custom animated/static game cursors were failing to load on macOS and Linux (falling back to the operating system's standard mouse cursor) due to an asset root propagation regression during the upstream file system merge and platform-specific gating in
