feat(mastervega): add V2 per-ship combat prototype with continuous-time simulation
Introduce `VegaCombatV2.js`, a parallel headless combat engine that simulates individual ships (not stack aggregates) in continuous time rather than discrete rounds. Ships have per-hull `sizeScale`, `sizeSpeedMult`, and `turnRateBase` fields; every entity tracks its own cooldown, position, facing, and angular momentum. Damage and movement are banked per-tick to preserve fairness. Accompanying files: - `VegaCombatViewV2.js` — zoomable/pannable Phaser view with parallax starfield - `VegaCombatCamera.js` — cursor-anchored zoom + drag-to-pan (listener cleanup on destroy to avoid stacking across battles) - `VegaFormations.js` — formation strategy plumbing (chosen per side, not yet read by movement/targeting) - Hull-specific destroy audio cues and vega buildings art Wired behind `?movsim`'s Live/V2 toggle in `VegaCombatSim.js` — the live engine and all real player battles are untouched. Also fixes several latent bugs discovered during the rewrite: - Trap 26: simultaneous wipe-out now checks draw before single-side wins - Trap 27: movement is banked (two-phase) like damage - Trap 28: weighted-random targeting tames chaotic nearest-neighbour sensitivity - Trap 29: fleet gap clamped to 85% world width to prevent starvation - Trap 30: `RANGE_EPS` tolerance prevents steering-induced standoffs See `docs/mastervega-build-plan.md` for full design notes.

World space is continuous 2D, not a lane, and combat runs in continuous simulated TIME, not discrete rounds: every ship has its own firing cooldown (turnSeconds, seconds between shots — armed the moment it first comes into weapon range of its target, matching real-time engagement rather than a synchronized lockstep round) and moves/turns continuously every tick rather than snapping once per round. moveUnitsPerSpeed is world units per SECOND now (was per old discrete round, at 100) — deliberately slowed down, not just time-converted, per Brian's explicit ask for a slower, more deliberate pace. turnRateScale converts each hull's turnRateBase (still degrees, still hand-tuned per hull, still living in the hulls block) into a per-second max angular velocity; spinUpSeconds is how long a ship takes to spin up to that max rate from a standing start, which is what gives turning real momentum instead of an instant snap. separationUnit/separationWeight tune the collision-avoidance steering (VegaCombatV2.js's computeSeparation) — separationUnit is the 'personal space' radius per point of a hull's sizeScale, so bigger ships keep proportionally more distance. beamRange/missileRange are unchanged by any of this (spatial, not temporal) — every other combat constant (hit-chance coefficients, cloakEvasion, singularityShieldPierce) is shared by reading rules.combat directly, since none of it is range/position/time-scaled; retreatAfterRound/disengageRound are reinterpreted as seconds (×turnSeconds) rather than duplicated here.",

25. **A per-function `scene.input`/`scene.events` listener has to be
|
||||||
|
unregistered by whoever adds it, if that function can run more than once
|
||||||
|
per scene session.** `VegaCombatCamera.js` (2026-08-09, built for the V2
|
||||||
|
per-ship combat prototype below) copies `VegaStarMap.js`'s zoom/pan
|
||||||
|
pattern — but `VegaStarMap` is instantiated exactly once per game and its
|
||||||
|
listeners live for the whole session, while `openCombatViewV2()` is a
|
||||||
|
plain function invoked **once per battle**, and the game opens several
|
||||||
|
battles in a row within one scene session
|
||||||
|
(`MasterOfVegaGame.playPlayerBattles()` loops over pending fights).
|
||||||
|
Copying the star map's "bind once, never unbind" habit would stack
|
||||||
|
another listener — with a stale closure over an already-destroyed
|
||||||
|
`battleRoot` container — on top of every earlier battle's, first as a
|
||||||
|
leak, then as a crash the moment a stale listener fires. `bindZoomPan()`s
|
||||||
|
`destroy()` explicitly `scene.input.off(...)`s every listener it added
|
||||||
|
(plus `scene.events.off('update', ...)` for the parallax tick) for this
|
||||||
|
reason, and both of `VegaCombatViewV2.js`'s teardown paths (`finish()`
|
||||||
|
and the escape-hatch `destroy` it returns) call it unconditionally.
|
||||||
|
Caught by design review before it was ever wrong, not by debugging a
|
||||||
|
live crash — worth writing down anyway, since it is exactly the kind of
|
||||||
|
thing a future contributor copying the star map's pattern elsewhere
|
||||||
|
would miss on the first pass.
|
||||||
|
|
||||||
|
26. **A simultaneous wipe-out must be checked before either single-side win
|
||||||
|
condition, or it silently favours one side.** Both engines' round-
|
||||||
|
resolution end with `if (!aLeft.length) {...defender wins...} else if
|
||||||
|
(!dLeft.length) {...attacker wins...}` — if BOTH sides' last living
|
||||||
|
unit dies to the same banked round, `!aLeft.length` is true first and
|
||||||
|
the `else if` never even checks `dLeft`, so the defender is declared the
|
||||||
|
winner despite being equally dead. This bug is verbatim in
|
||||||
|
`VegaCombat.js` too, but at stack granularity it needs an entire
|
||||||
|
multi-ship stack to die in the same round — rare enough that the live
|
||||||
|
engine's test suite (built around 5-ship stacks) never surfaced it. At
|
||||||
|
the V2 per-ship prototype's one-ship-per-side granularity it is common
|
||||||
|
(measured ~19% of 1v1 mirror-match trials) and was the single largest
|
||||||
|
contributor to an early 1v1 mirror-match bias caught during this
|
||||||
|
rewrite's own calibration (attacker winning only 38% instead of ~50%).
|
||||||
|
Fixed in `VegaCombatV2.js` with an explicit `!aLeft.length &&
|
||||||
|
!dLeft.length → draw` check ahead of the single-side cases. **Not**
|
||||||
|
fixed in `VegaCombat.js` — out of scope for a same-session parallel-
|
||||||
|
prototype build, and its real-world impact there is low given multi-ship
|
||||||
|
stacks — but worth fixing there too if this engine ever graduates, or
|
||||||
|
even standalone, since it is a genuine one-line correctness bug.
|
||||||
|
|
||||||
|
27. **Movement must be banked like damage, or whichever side's tie-break
|
||||||
|
"goes first" in a round quietly wins.** `VegaCombat.js`'s own comment
|
||||||
|
explains at length why *damage* is banked (applied together after
|
||||||
|
everyone has fired, so firing order can't decide who survives to shoot
|
||||||
|
back) — but the V2 prototype's first pass at *movement* missed the same
|
||||||
|
lesson: each ship moved immediately, in `order` (initiative, tie-broken
|
||||||
|
by a stable per-battle `seq`), so a ship that moved earlier in a round
|
||||||
|
reacted to the *current* (already-updated-this-round) position of any
|
||||||
|
enemy that had already moved, while a later mover was still working from
|
||||||
|
stale data — and since ties always favour the lower `seq`, one side
|
||||||
|
consistently had the informational edge. An isolated mirror-match soak
|
||||||
|
(identical fleets, no advantage either direction) swung from 0% to 65%
|
||||||
|
attacker wins purely from fleet size, with nothing else changed. Fixed
|
||||||
|
by making movement two-phase exactly like damage: every ship computes
|
||||||
|
its new facing/x/y against the same pre-round snapshot (`computeMove()`,
|
||||||
|
pure, no mutation), and only once every ship has computed one are any of
|
||||||
|
them actually applied. Same fix shape as `VegaCombat.js`'s own banked-
|
||||||
|
damage lesson, just for a different piece of per-round state — a
|
||||||
|
reminder that "banked, not sequential" is a property every per-round
|
||||||
|
mutation needs, not something you get once and keep for free.
|
||||||
|
|
||||||
|
28. **Hard nearest-neighbour targeting is a chaotic system at 5-20 discrete
|
||||||
|
ships per side, not a smooth attrition curve.** Even after fixing traps
|
||||||
|
26 and 27, a 5v5 mirror match still showed a 28-point win-rate bias, and
|
||||||
|
changing nothing but the placement grid's cell-spacing constant flipped
|
||||||
|
an otherwise-identical mirror match from 100% attacker wins to 0%.
|
||||||
|
Root cause: with strict "always target the mathematically nearest enemy"
|
||||||
|
for both movement and firing, *which* ships end up duelling *which*
|
||||||
|
other ships is a hard, deterministic function of exact sub-pixel
|
||||||
|
geometry — a tiny perturbation can flip who wins the first exchange,
|
||||||
|
which changes who's left to form the next pairing, cascading into a
|
||||||
|
completely different battle. This is a real property of nearest-
|
||||||
|
neighbour target-locking at small N, not a coding mistake to hunt down
|
||||||
|
further. Mitigated (not eliminated) with `pickWeighted()` in
|
||||||
|
`VegaCombatV2.js`: target choice is weighted by `1/distance²` rather
|
||||||
|
than winner-take-all nearest, for both movement's "which enemy to close
|
||||||
|
on" and firing's "which in-range enemy to shoot." This tames the
|
||||||
|
sensitivity (worst observed mirror-match bias dropped from 78pp to
|
||||||
|
~15pp) without abandoning "ships prefer close targets," but real
|
||||||
|
residual variance remains — the V2 verifier section's mirror-bias check
|
||||||
|
uses a deliberately looser tolerance (25pp) than the live engine's
|
||||||
|
(12pp), and the softening also dilutes small deliberately-subtle edges
|
||||||
|
like the cloak/singularity calibration (see trap 24) from ~62% down to
|
||||||
|
~53-55% — still a real, correctly-directioned, non-noise signal, just a
|
||||||
|
much smaller one. A smarter, non-degenerate placement/targeting model
|
||||||
|
(formation-aware, not raw nearest-neighbour) is the natural next step
|
||||||
|
when ship placement itself is revisited — deliberately deferred for now,
|
||||||
|
per the feature's own scoping.
|
||||||
|
29. **In a continuous-time engine, movement is no longer free — a placement
|
||||||
|
gap overflow starves combat of time to actually happen, not just of
|
||||||
|
space.** Converting V2 from discrete rounds to continuous seconds (see
|
||||||
|
the "continuous fluid battle" section below) meant closing distance now
|
||||||
|
spends real time from the *same* budget that also governs firing
|
||||||
|
cooldowns and the disengage timer, unlike the old discrete-round model
|
||||||
|
where movement was effectively free. This turned a latent placement bug
|
||||||
|
into an acute one: for large/mixed fleets (e.g. 17 ships/side including
|
||||||
|
battleships), `gap = GAP_MULT(3) × max(gridW)` could compute a gap far
|
||||||
|
exceeding `worldWidth`, placing ships at literally negative X. With that
|
||||||
|
much distance to close, only the fastest hulls ever got into range
|
||||||
|
before the disengage timer fired on a tiny, unrepresentative skirmish —
|
||||||
|
which is what actually decided the whole battle, reintroducing a 22pp
|
||||||
|
mixed-hull mirror-match bias that traps 27/28's fixes didn't touch
|
||||||
|
(they weren't the cause here). Fixed by clamping the gap in
|
||||||
|
`placeFleets()` to never exceed 85% of `worldWidth`. Lesson: a formula
|
||||||
|
that "only" affects starting positions can still be a *pacing* bug once
|
||||||
|
the engine treats travel time as a scarce resource.
|
||||||
|
30. **A movement "stop at range" distance and a firing "in range" check must
|
||||||
|
agree, or ships can park forever just outside their own weapons' reach.**
|
||||||
|
After fixing trap 29, battles still occasionally stalled outright (not
|
||||||
|
just biased) — surviving ships sat at full HP, unchanged for hundreds of
|
||||||
|
simulated seconds, all parked at `dist` reading exactly `beamRange` to
|
||||||
|
one decimal place. Root cause: `computeShipMove()`'s stopping distance
|
||||||
|
(`want = dist - beamRange`) assumes movement happens straight down the
|
||||||
|
seek line, but actual movement follows `step.facing`, which drifts off
|
||||||
|
that line whenever separation steering blends in — i.e. almost any time
|
||||||
|
a ship has a neighbour inside its `avoidRadius`, exactly the crowded
|
||||||
|
end-of-battle situation where the last few ships per side are bunched
|
||||||
|
up. The component of motion actually along the seek line ends up
|
||||||
|
slightly *less* than the computed `moveDist`, so a ship can settle into
|
||||||
|
a stable equilibrium a hair outside its hard weapon range and never
|
||||||
|
close the last fraction of a unit — permanent for any weapon with
|
||||||
|
finite ammo once its only unlimited-ammo mount (a beam) is excluded
|
||||||
|
forever by a strict `dist > range`. Fixed with a small tolerance
|
||||||
|
(`RANGE_EPS = 4` world units) on both the per-mount firing check in
|
||||||
|
`fireMounts()` and the cooldown-arming check in `advance()` — "close
|
||||||
|
enough" is the correct semantics for a steering approximation, not
|
||||||
|
bit-exact geometry. Confirmed fixed by driving the same stalled seeds to
|
||||||
|
a hard-uncapped duration (`maxRounds` overridden to 5000): every
|
||||||
|
previously-stalled battle now resolves.

*see* individual ships (sized by hull: frigate/destroyer/cruiser/battleship
|
||||||
|
at 0.5×/1×/1.5×/2.5×, `sizeScale`), watch hull-appropriate movement/turn
|
||||||
|
speed (`sizeSpeedMult`/`turnRateBase`, new per-hull fields in
|
||||||
|
`data/mastervega-rules.json`'s `hulls` block — additive, ignored entirely by
|
||||||
|
the live engine), and zoom/pan a battle with a parallax starfield — none of
|
||||||
|
which the old one-marker-plus-"×N"-label stack view could show. Brian
|
||||||
|
explicitly chose **true per-ship targeting** (every ship independently picks
|
||||||
|
its own target and rolls its own to-hit, no formation aggregation) over a
|
||||||
|
lower-risk "aggregate math, individual rendering only" option, understanding
|
||||||
|
that would mean re-deriving/re-validating the balance math — see traps
|
||||||
|
25-28 above for what that actually took.
|
||||||
|
|
||||||
|
- **New files**: `VegaCombatV2.js` (headless, mirrors `VegaCombat.js`'s
|
||||||
|
`createBattle`/`stepRound`/`runBattle`/`battleResult` contract and
|
||||||
|
`battleResult()`'s exact output shape, but `battle.ships` is a flat array
|
||||||
|
of individual entities with real `hp`/`x`/`y`/`facing`, not
|
||||||
|
`battle.stacks`), `VegaCombatCamera.js` (Phaser-touching zoom/pan/
|
||||||
|
parallax, adapted from `VegaStarMap.js` — see trap 25),
|
||||||
|
`VegaCombatViewV2.js` (Phaser rendering, one container per ship not per
|
||||||
|
stack).
|
||||||
|
- **World space is continuous 2D**, not the live engine's 1D lane — new
|
||||||
|
`rules.combatV2` block (`worldWidth`/`worldHeight`/`moveUnitsPerSpeed`/
|
||||||
|
`beamRange`/`missileRange`), completely separate from `rules.combat`'s own
|
||||||
|
`beamRange`/`missileRange` (which the live engine still reads unmodified).
|
||||||
|
1 old lane-tile = 100 new world units, chosen specifically so a
|
||||||
|
`sizeSpeedMult: 1.0` (destroyer) ship's pacing matches the live engine's
|
||||||
|
calibrated feel exactly — only the new per-hull multiplier introduces
|
||||||
|
deviation from it.
|
||||||
|
- **`hitChance()` and the shield-pierce/singularity math are copied
|
||||||
|
verbatim** from `VegaCombat.js` — the one thing explicitly not up for
|
||||||
|
revision. The only aggregation change in `fire()` is dropping the old
|
||||||
|
`shooter.count` multiplier (the shooter *is* one ship now); `sampleHits()`
|
||||||
|
is still reused per ship-mount, since a single hull can still carry many
|
||||||
|
copies of one weapon (e.g. 30+ lasers on a battleship).
|
||||||
|
- **Facing affects movement only** (Brian's explicit choice) — no firing
|
||||||
|
arcs, no to-hit modifier from facing, so the calibrated hit-chance formula
|
||||||
|
needed zero changes despite ships now having real headings.
|
||||||
|
- **Placement is deliberately a placeholder**: `placeFleets(rules,
|
||||||
|
attackerShips, defenderShips)`, exported standalone specifically so a
|
||||||
|
later rework can replace just that one function — a simple
|
||||||
|
few-columns/few-rows grid per side, per Brian's explicit ask to defer real
|
||||||
|
formation design. A deterministic per-ship y-wobble is load-bearing, not
|
||||||
|
decorative — see trap 28's root cause. Originally per-side
|
||||||
|
(`placeShips(rules, side, ships)`), called once each for attacker and
|
||||||
|
defender; changed same day (see below) to place both fleets together,
|
||||||
|
because the gap *between* them needs to know both footprints at once.
|
||||||
|
- **Sound**: reuses last session's Mark-banded weapon/missile sfx keys and
|
||||||
|
stagger mechanism, but caps actual cue playback at ~12 per round
|
||||||
|
(evenly sampled across the round) regardless of how many of the round's
|
||||||
|
60-150+ individual fire events there are — every event still gets full
|
||||||
|
visual FX, only audio is capped. Also gained one destroy cue per warship
|
||||||
|
class (frigate/destroyer/cruiser/battleship), sharing the same round
|
||||||
|
stagger timeline so a multi-kill round doesn't clip them together.
|
||||||
|
- Verifier: section 11 (headless like everything else) — ship-expansion
|
||||||
|
shape, determinism, the turn-rate invariant, a mirror-bias check at a
|
||||||
|
deliberately looser tolerance than the live engine's (see trap 28), the
|
||||||
|
cloak/singularity A/B calibration (see the fleet-size note below), and
|
||||||
|
(same day) formation-strategy resolution/stamping and the
|
||||||
|
placement/zoom-fit math below.
|
||||||
|
- Never browser-tested, per [[feedback_no_auto_verify]].
|
||||||
|
|
||||||
|
**Formation strategy, same day**: a `formationStrategy` chosen once per side
|
||||||
|
before a battle starts — `VegaFormations.js` (new, headless) defines two to
|
||||||
|
start, "Power Pressure" and "Speed Swarm", with `randomFormationStrategy(rnd)`
|
||||||
|
for a silent pick. `VegaCombatV2.createBattle()` resolves each side's choice
|
||||||
|
(honouring an explicit, valid one; silently rolling from the battle's own
|
||||||
|
seeded `rnd` otherwise — this is *all* "AI picks silently" needed, no
|
||||||
|
separate decision logic) and stamps it onto every ship on that side plus
|
||||||
|
`battle.attackerFormation`/`defenderFormation`. `VegaCombatSim.js`'s Watch
|
||||||
|
Battle (V2 mode only) shows a `modalShell` picker for the attacker before
|
||||||
|
launching; the defender gets no prompt at all. **This is plumbing only —
|
||||||
|
formation strategy does not yet affect placement, movement, or targeting.**
|
||||||
|
That's explicitly upcoming work; today it's just data flowing through so
|
||||||
|
that work has somewhere to read from.
|
||||||
|
|
||||||
|
**Bigger battlefield + fleet-size-adaptive initial zoom, same day**: two
|
||||||
|
requests that turned out to be coupled. `rules.combatV2.worldWidth/worldHeight`
|
||||||
|
went from 1200×800 to 3600×2400 (3×, same aspect ratio). Separately,
|
||||||
|
`VegaCombatCamera.bindZoomPan()` gained a `fitBounds` option — given a
|
||||||
|
bounding box (world units), it picks the zoom ladder's largest rung that
|
||||||
|
still frames the box without cropping it
|
||||||
|
(`VegaZoom.pickFitZoomIndex`, pure/headless), instead of always opening at
|
||||||
|
the ladder's fixed bottom rung. `VegaCombatV2.shipBounds(ships)` computes
|
||||||
|
that box from the actual battle (every entity including the planet, so a
|
||||||
|
fleet-vs-planet fight with no defender ships still frames correctly).
|
||||||
|
|
||||||
|
The coupling: the **first** placement pass just widened `GRID_MARGIN` — kept
|
||||||
|
each fleet pinned to a fixed distance from the world's edges, unchanged in
|
||||||
|
principle from before, just now measured against a 3× bigger world. That
|
||||||
|
was wrong. Because the margin was fixed regardless of fleet size, the two
|
||||||
|
fleets always ended up separated by roughly `worldWidth - 2×margin` no
|
||||||
|
matter how many ships were in them — a 1-ship skirmish and a 20-ship fleet
|
||||||
|
action opened with the *same* ~3300-unit gap, so `shipBounds`'s width was
|
||||||
|
dominated entirely by the world's size, not the fleet's, and the "adaptive"
|
||||||
|
zoom always picked the same bottom rung regardless of ship count — silently
|
||||||
|
defeating the entire feature while every individual piece of it (in
|
||||||
|
isolation) looked correct. Fixed by replacing the fixed-margin placement
|
||||||
|
with `placeFleets(rules, attackerShips, defenderShips)`: the gap between
|
||||||
|
fleets is now `3×` the larger fleet's own footprint width (floored at 900
|
||||||
|
world units so even a lone ship has room to use missile range before beam
|
||||||
|
range), and the whole attacker-gap-defender span is centered in the world.
|
||||||
|
A small battle now opens as a small, tight, centered cluster; a big one
|
||||||
|
spans proportionally more of the bigger world — which is what makes
|
||||||
|
`shipBounds`'s size actually track ship count, which is what makes
|
||||||
|
`pickFitZoomIndex` actually vary. **Lesson: an "adaptive to X" feature is
|
||||||
|
only as adaptive as whatever produces the data it reads — the zoom code was
|
||||||
|
correct from the start and still produced a non-adaptive result, because
|
||||||
|
the placement code feeding it wasn't actually a function of the thing being
|
||||||
|
adapted to.** Also had to move the defended-planet's position off a fixed
|
||||||
|
`worldWidth - 60` (which put it far from a defender fleet now placed near
|
||||||
|
the world's center) onto `layout.defenderEndX + 220`, returned by
|
||||||
|
`placeFleets` for exactly this purpose.
|
||||||
|
|
||||||
|
Also discovered while re-calibrating after the placement change: the
|
||||||
|
cloak/singularity A/B check (section 11) needs 10 ships per side, not the 5
|
||||||
|
used everywhere else in that section, to read a stable signal — at 5-a-side
|
||||||
|
the softened (weighted-random) targeting's pairing chaos fully swamps a
|
||||||
|
deliberately subtle 2%/0.5-shield-point edge (~48-50%, indistinguishable
|
||||||
|
from noise); at 10-a-side there are enough simultaneous ship-vs-ship duels
|
||||||
|
for the law of large numbers to smooth that out, and the same edge reads a
|
||||||
|
stable ~69-70% — comparable in spirit to the live engine's own ~62%
|
||||||
|
calibration. Not a regression to chase further, a real property of small-N
|
||||||
|
per-ship combat, same family as trap 28. **Superseded by the continuous-time
|
||||||
|
rewrite below** — the added movement/collision-avoidance chaos washed this
|
||||||
|
out further; see that section for the current numbers (15/side, ~55-57%).
|
||||||
|
|
||||||
|
**Continuous "fluid battle" rewrite, same day**: replaced the discrete
|
||||||
|
turn/round model with a real continuous simulation, per Brian's explicit
|
||||||
|
ask — "do away with the turn concept... make this a single fluid battle."
|
||||||
|
`stepRound(b, orders)` (whole-battle, lockstep) became `advance(b, dt,
|
||||||
|
{allowRetreat})` (fixed `SIM_DT = 1/30`s tick), driven either headlessly by
|
||||||
|
`runBattle()`'s tick loop or in real time by the view's own accumulator (see
|
||||||
|
below). The old discrete "round" became a per-ship **cooldown**: every ship
|
||||||
|
tracks its own `cooldown` timer, independently arms it (`turnSeconds = 2`s,
|
||||||
|
`data/mastervega-rules.json`'s `combatV2` block) the moment its target comes
|
||||||
|
into range — not from battle start — and fires when it hits zero. Damage
|
||||||
|
stays **banked** (`queueDamage`/`applyPendingDamage`, into `b.pending`) for
|
||||||
|
the same reason movement already was (trap 27): tried applying it
|
||||||
|
immediately first, on the theory that independent per-ship cooldowns would
|
||||||
|
rarely land on the exact same tick — wrong, because every ship shares the
|
||||||
|
same `turnSeconds` cadence, so ships that arm around the same moment stay
|
||||||
|
synchronized on every later cycle too, recreating the old "whoever's
|
||||||
|
processed first this tick wins" bias (22pp on a mixed-hull mirror match)
|
||||||
|
right back.
|
||||||
|
|
||||||
|
Movement gained real physics: ships now carry **angular momentum**
|
||||||
|
(`angularStep()` — a bang-bang accelerate/decelerate controller with a
|
||||||
|
`stopDist = ω²/2·accel` braking-distance check, tuned so a hull never
|
||||||
|
overshoots its target heading and oscillates) instead of snapping to a
|
||||||
|
heading instantly, and **collision avoidance** (`computeSeparation()` —
|
||||||
|
quadratic falloff by penetration depth into `avoidRadius = sizeScale ×
|
||||||
|
separationUnit`, blended with the seek-the-target vector). One easy-to-miss
|
||||||
|
design point: the tangential push direction in `computeSeparation()` must be
|
||||||
|
a **fixed** rotation (`px, py = -ry, rx`, always the same handedness) not a
|
||||||
|
per-ship-parity choice — a per-ship approach was tried first and silently
|
||||||
|
cancelled out on exactly the case that matters most, two ships approaching
|
||||||
|
head-on, because that geometry is already anti-symmetric between the two
|
||||||
|
ships and a parity-based tiebreak fights itself. Movement itself was
|
||||||
|
deliberately slowed down (`turnRateScale`, `moveUnitsPerSpeed` retuned down)
|
||||||
|
per Brian's explicit ask, on top of whatever slowdown the momentum/avoidance
|
||||||
|
math added on its own.
|
||||||
|
|
||||||
|
Traps 29 and 30 (above) were both surfaced by this change specifically —
|
||||||
|
continuous time turns "how long does closing distance take" from a free
|
||||||
|
action into something that competes for the same time budget as everything
|
||||||
|
else, which is what made a latent placement-gap bug (29) and a movement/
|
||||||
|
firing range-check disagreement (30) both newly acute enough to decide
|
||||||
|
battles or stall them outright. With both fixed, the mixed-hull mirror bias
|
||||||
|
that trap 28 could only mitigate to ~15-25pp is now **fully gone** (49.5% /
|
||||||
|
50.5% measured on a 17-ship/side mixed fleet over 200 seeds) — it turned out
|
||||||
|
to be almost entirely a symptom of traps 29/30, not the targeting chaos
|
||||||
|
trap 28 described. Same-hull mirrors still lean defender by a modest amount
|
||||||
|
(~5-12pp across tested fleet sizes) — inherited unchanged from the live
|
||||||
|
engine's deliberate "an attacker being beaten badly leaves early" early-exit
|
||||||
|
rule (`applyAutoOrders`, asymmetric by design, not a new bug), just more
|
||||||
|
visible now that battles reliably run to a real conclusion instead of being
|
||||||
|
dominated by the old stall/disengage noise.
|
||||||
|
|
||||||
|
`VegaCombatViewV2.js` was rewritten to match: "Next round" became
|
||||||
|
**Play/Pause**, driven by a real-time accumulator on the scene's own
|
||||||
|
`update` event (same register-once-per-battle/`off()`-in-`destroy()`
|
||||||
|
lifecycle as trap 25's camera fix — this is a second, independent listener
|
||||||
|
needing the same discipline). Ship containers are set directly to the
|
||||||
|
engine's real `x`/`y`/`facing` every frame rather than tweened between
|
||||||
|
round snapshots, since the sim already produces smooth motion at 30
|
||||||
|
ticks/sec — a tween on top of that would only add lag. Sound went from
|
||||||
|
"~12 cues sampled per round" to **rate-limited over real time**
|
||||||
|
(`SOUND_MIN_GAP_MS`/`DEATH_SOUND_MIN_GAP_MS`, a minimum gap between cue
|
||||||
|
starts) since fire events now arrive as a steady trickle rather than one
|
||||||
|
big per-round batch — every event still gets its full visual FX, no
|
||||||
|
sampling needed for that any more.

* `{ applyZoom, clampPan, getZoomIndex, destroy }` — call `destroy()` when

* the battle view closes, unconditionally, even if the view is also about
|
||||||
|
* to `layer.destroy()` its containers; the listeners live on `scene.input`/
|
||||||
|
* `scene.events`, not on `root`, so destroying `root` alone does not remove
|
||||||
|
* them.
|
||||||
|
*
|
||||||
|
* `worldW`/`worldH` size the zoom ladder (see VegaZoom.buildZoomLadder) and
|
||||||
|
* the pan-clamp bounds; `steps`/`maxZoom` default to a closer, finer ladder
|
||||||
|
* than the galaxy map's, since a battle world is fixed-size and benefits
|
||||||
|
* from a genuine close-up on individual ships. `parallaxLayers` (from
|
||||||
|
* buildParallax, if any) are repositioned every frame at their own rate as
|
||||||
|
* `root` pans — purely position-based, not rescaled with zoom, same as the
|
||||||
|
* star map's starfield.
|
||||||
|
*
|
||||||
|
* `fitBounds` (world units, `{minX, minY, maxX, maxY}` — see
|
||||||
|
* VegaCombatV2.shipBounds()) picks the starting zoom to frame that box
|
||||||
|
* (plus `fitPadding` on every side) instead of `defaultIndex`'s fixed rung,
|
||||||
|
* via VegaZoom.pickFitZoomIndex — so a small skirmish opens zoomed in close
|
||||||
|
* and a big fleet action opens zoomed further out, both filling the screen
|
||||||
|
* with the actual fight rather than a fixed slice of a now much bigger
|
||||||
|
* world. Falls back to `defaultIndex` if omitted. Because `placeShips()`
|
||||||
|
* centers each side's grid on the world's own center in both axes, the
|
||||||
|
* world's center and the fleet's bounding-box center coincide exactly, so
|
||||||
|
* panning still just centers on the world below — only the zoom rung
|
||||||
|
* changes, not the centering math.
