Targeting correction: reticle = TORSO BORESIGHT, not a free mouse cursor (task #39)
Colleague flagged that targeting is torso-locked with no fine cursor. Correct: the pod stick's yaw drove the TORSO TWIST (MechControlsMapper -> HUD::SetFreeAimSlew(stick_x) @cockpit+0x28C, gated on torso-horizontal-enabled; hud.hpp:167) and reticlePosition @HUD+0x1FC is COMPUTED by HudSimulation from the mech pose quaternion + target geometry, zeroed to centre with no target (part_013.c:5680) -- never a free-floating cursor. The engine Reticle struct is general (shared with Red Planet); BT drives it from the torso boresight. Fix: - Removed the mouse-cursor slew (a mis-sourced stand-in from the RP-shared struct). The crosshair is now the torso boresight: BTTwistToReticleX(torsoTwist) = tan(twist) projected through the live per-axis projection. Dead-centre on the fixed-torso BLH (TorsoHorizontalEnabled=0); you aim by steering the whole mech. - BT_AIM="x y" retained as the headless test harness. Verified: face-to-face spawn -> HOT lock + aimed zone hits (36); BT_FORCE_TURN circling -> 31 no-target vs 1 HOT (steering off-target drops the lock, as it must). KB swept (combat-damage / gauges-hud / open-questions); checkctx CLEAN. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Reticle Execute @004cdcf0 RECOVERED: every HUD instrument now live (task #37)
The one un-exported gap in the reticle chain, read via capstone (tools/disas2.py; the annotated disasm preserved at reference/decomp/reticle_execute_004cdcf0.disasm.txt). Draw() is now a transcription of the real per-frame logic, and the HUD attr-table names (hud.hpp ids 4/5/6/8/A/B/C/D) are CONFIRMED by their Execute usage: - Range ladder: BAR from ladder-top to the caret + caret translate. - The bottom 21-tick tape is the TORSO-TWIST indicator (NOT heading): deflection = -/+(span/2) x (RotationOfTorsoHorizontal / twist limit), attrs 4/5/6. Fixed-torso BLH reads centred -- authentic static. - The circle-with-stem is the COMPASS (attr 0xD, rad->deg rotation) at (botX, botY - 3*tickMajor - 0.03), with the THREAT trail (attr 0xC) in its rotated frame: 0.05-unit attack-direction marks, fresh < 2s red, expiring at 6s. Port feed: player TakeDamage pushes the impact direction (dormant vs the passive test dummy). - Pips (composed into subB6): hidden when destroyed (attr 1 == 1), LIT when the fire cycle is LOADED (attr 0x1c == 2; port source rechargeLevel >= 1) else the dark charging ring; filtered by the weapon-GROUP bits (weaponMode & elementMask&0xF). Range plays NO part (the stored TargetWithinRange slots are never read by Execute). - Lock ring: subB9 at frame centre SPINNING 4 deg/frame while locked ([0x9d] is the spin matrix, not a heading list). - Target HOTBOX: a rectangle hugging the projected extents (x+-4 around the top-centre hotbox point, +1/-11.5 vertical; baked K=2.8145 -- the port projects through the live per-axis projection), switching to the edge arrows past +-1.6 or behind (BTProjectHotBox, L4VIDEO). - Reticle state Off/On + PrimaryHudOn full-HUD/simple-X switch, aim translate on slew move, 3D marker + PNAME player-name mesh identified (chain still deferred).

Aim coordinates: route all conversions through the true NDC (fixes the
sideways lock offset) The windowed present stretches the fixed 800x600 backbuffer into the client area while the projection's aspect follows the CLIENT (resize rebuild) -- so the dpl2d/reticle frame, the client frame and NDC only coincide for a backbuffer-shaped window. The mouse mapping and the square-frame ray shortcut (cx = rx*tanHalfFov) were exact at screen centre and drifted outward with a side-flipped sign: aiming left of the enemy locked as if right of it (user report). - BTSetAimProjection now publishes BOTH proj scales (P11 carries the aspect) + the backbuffer size (the dpl2d frame). NOTE: GetViewport at the loop top holds the PREVIOUS frame's last pass viewport (gauge passes shrink it) -> use the renderer's own GetWidth/GetHeight. - BTGetAimRay / BTProjectToReticle convert reticle <-> NDC per axis (ndc_x = rx * vh/vw; camera x = ndc_x/P11) -- exact for any window shape and FOV. - New BTClientToReticle undoes the present stretch for the mouse (client px -> viewport px -> reticle coords); mech4 uses it instead of the raw client-height mapping. - 1Hz aim telemetry in the [target] log (hits/noRay/noPick): verified 100% pick hit rate once the projection is live (the pre-visibility mission-load seconds report noRay -- that was the "flicker").

Authentic target acquisition LIVE: reticle slew + pick-ray lock + aimed zone damage (task #36)
The engine Reticle model (MUNGA/RETICLE.h [T0]) reconstructed end to end: - Mech::targetReticle is a real Reticle member bound to the TargetReticle attribute (0x1d), per the RP VTV analog (VTV.h targetReticle). - Crosshair slew: mouse -> client rect -> reticle coords (the pod stick free-aim channel's dev-box stand-in); BT_AIM="x y" pins it headless. LMB fires lasers / RMB missiles (alongside SPACE/CTRL). - Pick ray: the ACTIVE eye publishes pos + LookAtRH basis (BTSetAimCamera, L4VIDRND view-write site) + the render loop publishes proj._22; BTGetAimRay builds the world ray, Mech::PickRayHit slab-tests it against the collision template's ExtentBox via the engine's BoundingBox::HitBy (local frame; clips the Line at entry) -> world hull point. - Designation: the mech under the crosshair designates (sticky; re-hover refreshes; cleared when the target leaves the roster at burial); the entity target slots 0x37c/0x388/0x38c feed the whole weapon path. - Aimed fire: while HOT the impact point is the PICKED hull point -> the STEP-6 cylinder lookup resolves the zone under the crosshair (verified: center-aim -> head-band zone 13 dominant). Off-crosshair the sticky designation converges on center mass. - HUD: the aim group draws at the slewed position ([0x9a] translate, contained by push/pop); the designator ring tracks the target's projected point (subB9 hot / subB8 designated, BTProjectToReticle); edge arrows when off-screen/behind. - AUTHENTIC gating: no fire arc exists in the binary (FireWeapon fires whenever HasActiveTarget, part_013.c:7758) -> BT_FIRE_ARC is now an explicit OPT-IN presentation clamp; the hardwired gEnemyMech lock and the projectile path's gEnemyMech fallback are removed. - Fixed en route: every renderable rebuild stomped mCamera back to the chase eye (start-inside silently lost the cockpit camera; the aim feed exposed it). BTL4VideoRenderer::mViewInside persists the chosen view. Verified headless: BT_AIM="0 0" -> HOT lock, pick hits the hull face at exact range, aimed zones resolve; BT_AIM="0.8 0.3" -> no lock, zero damage, zero missile launches; kill chain completes to wreck + smoke.

HUD reticle + weapon pips LIVE: dpl2d 2D display-list port (task #35)
- dpl2d API fully recovered from the binary recorders (@487f34-488630): opcode model (points/lines/polyline/circle/color/width/matrix/push-pop), CallList = INLINE include (state persists to caller), centered coordinate frame (unit = half viewport height). game/reconstructed/dpl2d.cpp rework. - BTReticleRenderable ctor @004cc40c transcribed with the authentic calibration (originX .35, originY .25, scaleY .5, 0..1200m right range ladder, bottom heading tape, FUN_004cd938 tick ladders, lock rings, turn arrows); range caret slides from the live target range fed by the mech4 targeting step (BTSetHudTargetRange). - Weapon pips: the binary gate is IsDerivedFrom(0x511830 = MechWeapon::ClassDerivations) [T1: part_014.c:5386 hard-aborts on missing weapon attrs; part_012 counts + roster ORs capabilityFlags@+0x334] so ALL 7 BLH weapons register (3 lasers + 2 PPCs + 2 MissileLaunchers). Pip A (lit, authored PipColor) on TargetWithinRange, else dark ring B. - AddWeapon @004cdac0 store map corrected to the verified order (part_014.c:4827-4837); both state attrs are literally named "SimulationState" (strings @51d526/51d577) -> weapon simulationState. - Mech roster this[0x1ef] renamed poweredSubsystems -> weaponRoster (0x511830 is MechWeapon, not PoweredSubsystem=0x50f4bc); derivation-tag table added to context/decomp-reference.md. - Draw hook BTDrawReticle after the 3D scene, cockpit view only. Binary Execute @004cdcf0 is an un-exported gap -> Draw dynamics [T3], tracked in context/open-questions.md with the blx_cop canopy + PNAME pip meshes.

Beams at the models' NATURAL width, per-weapon tube models (de-cartooned)
The "cartoonish" beams: the port drew the ermlaser tube INFLATED -- a 3.0x glow + 0.9x core two-layer hack, 13x the authored radius. Parsed the beam models: ERMLASER/MLASER 0.22u radius, SLASER 0.11, LLASER 0.32, PPC 0.62 -- thin pencil beams with an authored per-class size progression; the PPC bolt is genuinely ~3x fatter with its own 62-vert shape. Now: ONE draw per beam at natural model scale (width multiplier 1.0), using the weapon's OWN tube model (ermlaser for lasers, ppc.bgf for PPCs; the s/m/llaser tubes load for other mechs' loadouts). BTPushBeamKind carries the model selector; BTPushBeam keeps its signature (kind 0). Tint = 40+215x the authored PipColor; the thin natural tubes stay under additive saturation so the scrolling grit reads without a hand-dimmed core layer.

Missiles: authentic dsrm smoke trail + torso aim (placeholder tracer removed)
The "white lines toward the feet" report: the LAUNCHES are authentic (the mech's real MissileLauncher/ProjectileWeapon roster subsystems firing on their own recharge cadence -- that's the every-Nth-shot rhythm), but the visual was the bring-up 3-segment beam tracer, and the aim point was the victim's ORIGIN (ground level between the feet). - Trail: per-frame puffs of the AUTHENTIC dsrm effect (psfx 0, "the lrm smoke trail") along the flight path, frame-oriented so the smoke streams behind the round (its .PFX velocities are +Z = backward); the round itself is a short hot streak. New BTPfxTrailPuff spawns slot particles directly at a moving point (no emitter instance). - Aim: the resolved target point lifts to torso height (the beams already converged there) -- impacts now cyl-resolve to body zones instead of diving at the feet/legs. Follow-up noted: the round MESHES (BULLET/LRMS.BGF ship) for a true model-per-projectile look. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Death = the burning WRECK-HULK swap (effect 104) -- the authentic chain, reconstructed
The user was right: a dead mech turns into a pile of wreckage. The authentic
1995 chain, recovered end-to-end:
kill -> the victim's per-mech DEATH ModelList ('blhdead'/'lokdead'/'owndead'/
'thrdead', .RES ids 22-25) -> its authored effects: 104 (the WRECK script) +
1007 (dnboom big explosion) + 1001 (ddthsmk rubble smoke plume) + a damage-
smoke burst (3/4/5/15).
Effect 104 = ExplosionScripts case 4 (part_008.c:2663, LIVE in the 1996 binary;
the "disabled" warning is case 6): loads the destroyed hulk + flamesml/flamebig
flame meshes with sweep flicker. Every mech ships its hulk (BLHDBR/MADDBR/
LOKDBR/... + GENDBR generic); the 1996 script hardcoded thrdbr.bgf (dev
shortcut) -- we use the victim's own.
Reconstructed as BTL4VideoRenderer::SwapToWreck: hide every segment mesh, hang
"<prefix>dbr.bgf" on the tree root (pending-swap if death precedes tree build);
routed from the engine's ExplosionClassID dispatch (effect 104 ->
BTSwapMechToWreck(explosion->GetEntityHit())). The kill now fires the
authentic 'blhdead' resource (manual 7+1 pfx calls removed -- the list carries
1007/1001 itself). Verified live:
[death] firing authentic death list 'blhdead' id=22
** effect_number = 104
[BTrender] wreck swap: victim -> 'blhdbr.bgf'
Follow-ups noted: mesh flames + hulk settle (cosmetic), DeathSplash.

PFX continuous-rate emission (data-verified) + persistent wreck smoke
The one-burst emitter batching was wrong: in EVERY shipped .PFX, maxIssue/rate == release_period (DAFC 25/100~=0.2, DNBOOM 35/150~=0.2, DDAM2 35/16~=2, DDTHSMK 30/3=10) -- release_period is the EMISSION WINDOW and rate is particles/second emitted continuously across it. The death smoke plume is authored as a 3/sec trickle for 10 seconds (+6s particle life), not one same-frame puff. Emitters now integrate rate*dt until maximum_issue. Wreck smoke (port addition, [T3]): a destroyed mech re-arms the death/rubble smoke plume (psfx 1, DDTHSMK) every 10s -- its own authored window -- so the dead hulk visibly keeps smoking instead of standing there looking alive (the freeze-death is invisible on an already-stationary target). New member Mech::wreckSmokeTimer; UpdateDeathState takes dt. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

Combat visible + killable: Wword root-cause fix, .PFX effect layer, RemakeEntity swap
The 'can't kill the enemy / no visible damage' cluster, root-caused and fixed faithfully: - STEP-6 unaimed path was INERT: the cylinder table was 'cached' at Wword(0x111) -- the recon ABSORBER bank (stores nothing, reads 0) -- so every unaimed hit silently no-op'd. Promoted to the named member Mech::damageLookupTable (binary this[0x111], was mislabeled ammoExpended). New gotcha class recorded (reconstruction-gotchas §2) + sweep; 2 dead multiplayer branches logged. - Fire path migrated off the stale vital-zone aim onto the completed STEP-6 unaimed dispatch (zone=-1 + beam entry point -> cylinder resolves the exterior zone). No more invisible 1-shot kills; death via the authentic cascade (~14 center-mass hits). Wreck stays TARGETED on kill (beams stop on it); scoring latches off. - SendSubsystemDamage AV fixed: unbound critical-subsystem plug guard (43 unbound plugs/mech logged as an open question -- the binding itself is a gap). - RemakeEntity (render damage swap): the 1996 render state machine's missing Remake state, reconstructed as an in-place SetDrawObj mesh swap keyed by each segment's damage-zone graphic state (tree dtor doesn't cascade -> never rebuild). Destroyed arms/guns visibly wreck (the only variants the RES registers). - BT .PFX particle layer (L4VIDEO.cpp): the 1995 explosion/damage effect layer, unported since 2007 (DPLIndependantEffect/ReadPSFX/ExplosionScripts all stubs). Parses the authentic VIDEO/*.PFX definitions via the [pfx_day] psfxN mapping; premultiplied blending renders BOTH families from the same data (additive-style fire + occluding smoke -- DDAM2 is 30% grey, DDTHSMK ramps negative: impossible additively); depth-sorted billboards with a radial-masked grit sprite; impact-frame orientation (.PFX offsets are authored mech-local, -Z = out of the struck armor toward the shooter) for weapon hits AND damage bands (via lastInflictingID, now maintained -- was declared but never written). Both effect-number encodings route (raw dpl <100 + WinTesla 1000+slot carried by the band resources). Death fires the authentic dnboom (7) + ddthsmk smoke plume (1). - Effects anchor at the impact point / damaged zone's segment, not the mech origin (no more fire at the feet). - Dev force-input gates BT_AUTOFIRE / BT_AUTODRIVE for headless fire-chain verification; BT_PFX_ADD=1 flips the particle blend for A/B.

gauges: all 6 cockpit MFD surfaces in a SEPARATE dev window (Milestone C)
Generalizes the single-'sec'-inset (Milestone B) into a full 6-surface compositor presented in its own top-level window -- the default under BT_DEV_GAUGES (BT_DEV_GAUGES_DOCK=1 docks it into the main window instead). A 960x384 window tiles all six pod instrument screens: Heat (COOLANT/BALANCE/ RES + condenser gauges), Comm (KILLS/DEATHS/SELECT TARGET), Mfd1/2/3 (DISPLAY/ PROGRAM/NEAREST frames), and the color radar (SCALE grid + dials + ARMOR DAMAGE). Main 800x600 3D view is un-occluded; default DEV un-regressed (TARGET DESTROYED after 8 hits, 0 crashes). Design (mapped by the mfd-multisurface-map workflow): - All 6 surfaces are bit-plane MASKS over the ONE shared SVGA16/pixelBuffer (sec=palette low byte; Heat=0x4000 UL, Mfd2=0x0400 UC, Comm=0x8000 UR, Mfd1=0x0100 LL, Mfd3=0x1000 LR), so the compositor reaches the SVGA16 once and extracts each by mask. No port-name reconcile needed on the dev path -- fetch the BT names directly; the RP aux* names only matter to the pod's own SVGA16::Update demux (a deferred pod-only fallback). - SVGA16::DrawDevSurface: two kernels -- palette-LUT (sec) + mono bit-plane-> tint ((word&mask)?tint:0). BTDrawGaugeSurfaces iterates a 6-entry table. - Separate window = one CreateAdditionalSwapChain on the existing device (no 2nd D3D device). BTGaugeWindowRenderAndPresent (after the main EndScene): SetRenderTarget -> SetDepthStencilSurface(NULL) -> Clear -> BeginScene -> 6 tiles -> EndScene -> restore -> swap->Present. - KEY BUG fixed: the main 800x600 depth surface stays bound when rendering to the 960x384 gauge backbuffer; a bound depth smaller than the RT is invalid -> all draws silently fail (clear color, no geometry). Unbind depth (Z is off), restore after. Pod SVGA16::Update/BuildWindows path byte-unchanged; all gated BT_DEV_GAUGES. Content is still the authored cockpit frames + base-table gauges -- the live MFD widgets need the BTL4MethodDescription reconstruction (this window is now the live viewer for that work).

gauges: secondary/radar MFD composites live on a dev box (Milestone B)
The pod's secondary/radar cockpit surface now renders as an inset in the 800x600 dev window under BT_DEV_GAUGES: radar/tactical grid, SPEED/HEADING/ MAGNETIC/PROP dials, and the color-coded ARMOR DAMAGE mech schematic -- real gauge content (nzSec=27247), composited from the shared CPU pixelBuffer. Composite pass (engine): SVGA16::DrawDevInset palette-expands the secondary plane into a MANAGED texture on the MAIN device and draws an XYZRHW inset quad; BTDrawGaugeInset() reaches the gauge renderer's 'sec' port and is called from DPLRenderer::ExecuteImplementation as the last draw before EndScene. Three reconstruction bugs fixed to get real content: 1. BTL4Application::MakeGaugeRenderer signature mismatch (REAL fix): the reconstructed no-arg override only HID the 2007-engine's widened 3-arg virtual MakeGaugeRenderer(int*,int*,int*), so the engine built a base L4GaugeRenderer whose ctor never parsed gauge/l4gauge.cfg -> empty symbol table -> "undefined label 'bhk1Init'" -> no ports/gauges. Matched the 3-arg signature so it truly overrides (args ignored; BT is fullscreen). Same bug class as the BTL4GaugeRenderer(false,NULL,NULL,NULL) ctor fix. 2. Parse hung on undefined primitives (gated dev accommodation): the BT gauge primitive table (BTL4MethodDescription) is still a stub, so an unknown primitive -> ReportParsingError -> Fail() -> a MODAL dialog freezing the parse. Under BT_DEV_GAUGES, skip the unknown primitive's params so labels register and the base "configure" primitive builds the ports. 3. Gauge widgets AV on NULL data bindings (gated): NumericDisplayScalar's NULL value_pointer -> GaugeConnectionDirectOf ctor deref (bind NULL->static zero); RankAndScore::Execute derefs unreconstructed game state (Gauge::GuardedExecute SEH wrapper -> Disable(True) on first fault). All guards gated on BT_DEV_GAUGES: default DEV un-regressed (TARGET DESTROYED, 0 crashes) and the pod path is byte-unchanged (strict Fail, no guards). Remaining (docs/GAUGE_COMPOSITE.md): the real gauge WIDGET reconstruction (BTL4MethodDescription method table + gauge->game-state data bindings), then Step 2 (RP<->BT MFD port-name reconcile) + Step 3 (2-window layout).

Initial commit: bt411 -- standalone Windows BattleTech (Tesla 4.10 port)
Clean, self-contained extraction of the BattleTech-specific work from the
reverse-engineering workspace -- engine + game + content + build, with nothing
from Red Planet or the raw archive dumps. Builds green (Win32) and runs the
single-player drive->animate->target->fire->damage->destroy loop out of the box.
Layout:
engine/ MUNGA + MUNGA_L4 shared 2007 engine, carrying our BT render/loader
work (bgfload/L4D3D/L4VIDEO: BSL bit-slice decode, LOD/ground/shadow
models) + image codec; the minimal rp/ headers the audio HAL needs
game/ reconstructed BT logic + surviving-original BT source + fwd shims
+ WinMain launcher
content/ full runtime tree (BTL4.RES, VIDEO/, GAUGE/, AUDIO/, eggs, BTDPL.INI)
docs/ format specs + reconstruction ledgers
reference/ raw Ghidra pseudocode (recon source-of-truth) + decomp exporter
tools/ MP console emulator + map/resource scanners
One top-level CMake builds munga_engine lib + bt410_l4 game lib + btl4.exe.
All paths relativized (186 fwd shims + ~437 CMake abs paths -> repo-relative);
DXSDK is the one external, overridable via -DDXSDK. Verified: builds to a
byte-identical 2.27MB exe and runs combat (TARGET DESTROYED, 0 crashes) against
the bundled content.
