Completes the weapon-side half of the look commit: - MECHWEAP: real rearFiring/viewFireEnable members (binary @0x334/@0x3E0) + accessors. Ctor resolves REAR-FIRING authentically (@004b99a8 tail): the mount SEGMENT site name is tested for the 'b' (back) marker -- only the back gun ports (sitelbgunport/siterbgunport) carry it. Spawn = forward-armed. - MECH CommitLookState: re-arms every roster weapon per view (forward = non-rear, LOOK-BACK = rear-mounted, side/down = none) and flips the HUD reticle pip group with the authentic Reticle::Front/RearFiringWeaponsOn flags (BT411's raw "bits 1/2" resolved to their 1995 names). - MECHWEAP: defined MechWeapon::MessageHandlers (0-entry set inheriting the Subsystem chain) -- it was declared-but-undefined, and the surviving CODE PPC.CPP binds the inherited name into PPC::DefaultData; the zero-filled common block was a latent NULL deref (same trap as Emitter::AttributeIndex). Discovery: the TEST.EGG mech genuinely mounts TWO REAR LASERS (ERMLaser_2/3 on the b-ports). Verified on a full-clean baseline (engine 181 + bt 42, 0 fail): look-behind arms exactly the rear lasers, disarms the other five, pipMask=0xfffffffe; neutral run holds forward-armed; zero Fail. build410.sh HARDENED against the stale-obj layout-skew trap this wave exposed: cc() skipped recompiles on obj-vs-.cpp timestamps only, so the MECHWEAP.HPP member additions left emitter.obj on the OLD MechWeapon layout -- its chargeLevel=0.0f write landed exactly on the new rearFiring (a silent cross-TU struct skew, heisenbug-grade). cc() now honors header stamps: a source410 engine-header edit invalidates every bucket, a BT/BT_L4 header edit additionally invalidates the game buckets. CODE/ is immutable, no stamp needed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# MECHWEAP.CPP / .HPP — reconstruction notes
|
|
|
|
`MechWeapon` (: PoweredSubsystem) is the weapon base: PPC/GaussRifle bind it via
|
|
Emitter, the SRMs via ProjectileWeapon/MissileLauncher. The resource streams
|
|
rechargeRate / weaponRange / damage / heatCostToFire (+ pip fields).
|
|
|
|
## Reconstructed
|
|
|
|
- Statics (ClassDerivations, DefaultData on Subsystem::MessageHandlers/
|
|
AttributeIndex), ctor streaming the tuning fields, damageData prime.
|
|
- **View-fire gating (2026-07-21, the look-commit wave):** real `rearFiring` /
|
|
`viewFireEnable` members (1995 binary @0x334/@0x3E0) + `IsRearFiring()` /
|
|
`GetViewFireEnable()` / `SetViewFireEnable()`. The ctor resolves REAR-FIRING
|
|
authentically (binary ctor tail @004b99a8): the mount SEGMENT site name
|
|
(`owner->GetSegment(GetSegmentIndex())`) is tested for the 'b' (back) marker —
|
|
only the back gun ports (`sitelbgunport`/`siterbgunport`) carry it. Spawn
|
|
state = armed for the forward view. `Mech::CommitLookState` re-arms on every
|
|
view change (see MECH.NOTES.md increment 7). Verified: the TEST.EGG mech's
|
|
two rear lasers (ERMLaser_2/3) arm only in LOOK-BACK.
|
|
|
|
## Still staged
|
|
|
|
- `FireWeapon` (abstract here; the concrete fire paths in Emitter/PPC/Gauss/
|
|
MissileLauncher are the combat wave), `SendDamage` (damage/networking),
|
|
`CreateStreamedSubsystem` (tool-side model build).
|
|
- The 1995 MechWeapon attribute table (RearFiring @0x1B, EstimatedReadyTime,
|
|
...) is not yet published — our DefaultData still uses the base
|
|
Subsystem::AttributeIndex. Comes with the weapon-gauge/console wave.
|
|
- ~~`MechWeapon::MessageHandlers` declared but not defined~~ — **FIXED
|
|
2026-07-21**: it is now a real defined set (`(0, NULL,
|
|
Subsystem::MessageHandlers)` — no own handlers yet, inherits the chain), and
|
|
`MechWeapon::DefaultData` binds it. This mattered because the surviving CODE
|
|
PPC.CPP binds the inherited name (`PPC::MessageHandlers`) into
|
|
PPC::DefaultData, and a declared-but-undefined static links as a zero-filled
|
|
common block — the same silent-NULL trap as the Emitter::AttributeIndex
|
|
crash. Real weapon handlers (fire/damage messages) come with the combat wave
|
|
(grow the table in place).
