The sim displaces at once (battle/displacement.js), so the snapshots only show the destination: a ≤ 2.5-tile push was
lerped over one snapshot interval (3 frames, 0.58 tiles in one frame — frame-loop repro over a real battle), a longer
pull snapped. render/app.js now starts UnitView.slideTo as soon as the interval it samples ends on the snapshot that
carries the destination (a `displace` fx still queued up to SnapshotBuffer.nextSnapT); the view holds where it stood
until that snapshot is shown, then eases into the sampled position under a constant deceleration (v0 = 2D/T, a = v0/T,
T = 0.14·√D in 0.12–0.45 s — ours, [ASSUMED]: no source gives the official timing; docs/research/13 has the official
impulse-and-friction classes). A unit that dies on the way finishes the slide and lies where the push put it.
Death: DIE_CLIP_MAX 1.6 → 8 s (data/assets.json: 234 enemy Die clips, the longest 7.97 s, 25 over 1.6 s), and a
flyer holds FLY_HOVER until the fade tail (DIE_FADE_TAIL 0.55 s).
Substantially @xcdoge's code (PR #380: the slide, the death timing, research 13 / 14, most tests), authored as theirs.
Changed on review: the corpse no longer goes back to where it stood (the PR's test asserted that; the sim's body is at
the destination); the PR's pre-pass scanned (renderT − 0.5, renderT] after processEvents had taken those events, so
it never fired and the slide started a frame before landing — it now looks ahead to the next snapshot and holds the
view until then; the slide eases into the live sample instead of the fixed destination (no jump back onto an enemy
that walked on); each step uses its mean velocity (the end-of-step speed ran 9 % short, then jumped); the constants'
comments say the timing is ours; research 14 no longer cites a sweep script and a data guard that were not in the PR.
Golden: unchanged (client only).
Tests: test/render/unitview.test.js 35/35 (slide: deceleration, idempotence, facing, snapshots in flight, friction,
√D, corpse lies where pushed, hold-then-ease without a landing jump, a never-shown slide handed back; the app.js frame
order over a real battle: a 1.7-tile push over ≥ 8 frames with every step < 0.35 tiles, a push-kill's body staying at
the destination; death: a dying flyer's lift, every Die clip within DIE_CLIP_MAX and a 7.97 s clip scheduled whole);
test/sim/displace-fx.test.js 1/1; render/interp 16/16; docs tests pass.
Ported by hand from PR #211 by @xcdoge:
- render/units.js: FLY_HOVER 0.32 → 1.3, flat (the official fly offset is one model-independent Vector3(0, 0.35, 0) in
the client's character space, whose unit is the standard battle-prefab scale 0.27; an official screenshot measures
1.2–1.4 tiles); enemyModelScaleY multiplies the skeleton's Y scale and the head (bar) height, also in the impostor
path; a mirrorX model flips on top of the direction flip. The body, its HP bar, damage numbers, projectile hits and
skill rings ride `hover`, the shadow stays on the ground; one camera drives the units over the 2D and the 3D board.
- tools/build-data.mjs MODEL_STRETCH_Y / MIRRORED_PREFABS → enemies.json modelScaleY / mirrorX; data/enemies.json
regenerated offline here (the PR's one-line blob was not taken) — JSON compare: only enemy_1112_emppnt /
enemy_1112_emppnt_2 modelScaleY 1.263 and enemy_1196_msfyin mirrorX true.
- tools/local-extract/enemy_model_offsets.py (optional, host-side prefab reader) and
docs/research/12-flying-visuals-official.md (without the claim that the owner said 「都要」 on 2026-10-05 — the owner's
decision of 2026-10-06 is cited; where the quirk enemies appear corrected against 0.2.0's data: 帝国炮火先兆者 is a FLY
special enemy of the mode, 帝国炮火中枢先兆者 comes with the bounty 战术特训·飞行III, 木制瑞印 is in no wave). No
screenshot or extracted art committed.
Tests (from PR #211): test/render/unitview.test.js (FLY_HOVER ≈ 0.35 / 0.27; the same lift for every flyer; a flying
view lifts by FLY_HOVER — added here: its body and HP bar ride the lift, its shadow stays on the ground),
test/render/playtest6-enemies.test.js (the data keys; the 1.263 aspect and bar height; the mirrored model's x sign);
both fail without the renderer change; the 425 render unit tests pass. Docs: DATA §9, ASSETS, design client.md,
research 00 / 12, DESIGN §25.13.5 and the §25.10 table.
Golden unchanged (drawing only; the sim reads neither field).
- #1 picking by the tile under the pointer (prep, battle, pen, equipment drops); the dragged model stays
under the pointer (mouse and touch); pixel probe removed; phone ghost-click on the underframe fixed
- #2 two-tap confirm on 机变 cards (like the shop)
- #3 a 同盟 room with one human is untimed like 独立模拟 (no countdown outside battles)
- #4 strategy draft: one synced countdown, 30 s per human turn, timeout takes the highlighted band
- #5 special 维式重锤 (4) and 突变细胞 no longer sold; item card shows where they come from
- #6 operator skill-mode sounds no longer play on normal attacks (纯烬艾雅法拉 and 55 others)
- #7 detail card shows live battle stats and the prep-time battle-start stats (g.unitStats)
- #8 official element gauges on units; burst cooldown (阻回) per PRTS
- #9 knocked-down operators stay on their tile with a redeploy countdown ring
- #10 drone behaviour per PRTS (暴鸰, 先兆者 shells, 黑云, 萨科塔之眼)
- #11 赫默's drone only from her skill; placeable summons limited to talent tokens
- #12 炎佑 stays where it is with no enemies; 祛恶之焰 as a continuous channel
- #13 the occasional giant bond icon (loading texture scaled ×46) fixed
- docs (DESIGN §18), recordings, data and tests updated (2467 unit tests, all browser suites green)
- #1 lost operator models: the Spine store no longer hands out a skeleton whose unload is in flight
(PIXI.Assets.unload is async); eviction runs 1 s after a release and the empty-scene budget only after 3 s
- #7 picking: one shared rule (render/pick.js, pixel probe where bodies overlap) for prep/battle clicks,
hover, the enemy pen and equipment drops; the drag ghost stands on its drop tile; hover probes capped
at one per frame
- #2 the top-bar LP drops live as the own battle's enemies enter the blue gate (−N, 联防中), teammates'
pending LP in the team panel
- #3 temp overflow pieces that arrive after a prep deadline survive through the next prep (tempDue);
temp-row warning and ready-button reason
- #4 蕾缪安 S3: locks every 0.5 s, then one shell every 0.3 s in lock order (PRTS notes), bombardShell fx
- #5 回环射手: real boomerang (out 15, back 3.75 tiles/s, attack only when every boomerang is caught)
- #6 visible projectiles, muzzle flashes, slashes, skill bursts and auras at unchanged frame cost
- #8 特质 right under the detail card header, with its official type icon
- #9 no spinning busy cursors / spinners next to texts; game data warmed before the match
- docs, recordings and tests updated (2414 unit tests, all browser suites green)
