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.

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. + ### Ship rows carry video, so they have to be pooled Every place a ship is listed — the side panel's task force, its in-transit, diff --git a/smoke_broad4.mjs b/smoke_broad4.mjs new file mode 100644 index 0000000..70d02ba --- /dev/null +++ b/smoke_broad4.mjs @@ -0,0 +1,87 @@ +import { readFileSync } from 'node:fs';
