public/js/render/fx.js becomes a re-export barrel. Speeds, camera heights, fonts, the kind table and the shared tunables move verbatim into public/js/render/fx/*.js. FxSystem keeps its constructor, clear, update, counts and destroy; the other methods move verbatim into container classes installed on FxSystem.prototype in source order. simSpeeds and fontsReady each stay one instance. The dynamic import of /sim/constants.js stays next to setSimProjectileSpeeds.

// render/fx.js — battle visual effects with pooling and hard caps (DESIGN §9).
|
||
//
|
||
// projectiles b.ev 'atk' by projKind (render/style.js PROJ): sniper tracers with a muzzle flash; arts / heal / enemy
|
||
// orbs with a particle trail; bombs and lobs as shells on an arc with a ground shadow, a smoke trail and
|
||
// an explosion; drone darts; 回环射手 boomerangs that spin out to the target and back to the thrower's
|
||
// current position, gone when caught. Flight times from the sim's projectile speeds (/sim/constants.js
|
||
// PROJECTILE_SPEEDS — the visual lands with the sim's hit), homing on the interpolated target; a burst
|
||
// per kind on arrival; chain lightning (chain / chainHeal) and beams as short-lived jagged lines
|
||
// hits glow + sparks by damage type; a melee blow adds a slash crescent swept along the blow (attacker →
|
||
// victim) in the hit colour; AoE ground rings for splash attackers
|
||
// numbers damage numbers (phys orange-white, arts purple, true white, heal green, elements orange) as
|
||
// pooled BitmapText (per font); rapid same-style hits on a target merge into a running total; big hits
|
||
// (≥ 18 % max HP) pop larger; ≤ 4 per target; laid out in screen space against every live number (lanes
|
||
// beside the head, stacked upwards) so numbers of neighbouring units never cover or touch each other;
|
||
// crowded spots get shorter lives (see number())
|
||
// skill activation burst: flash, a light pillar with a white-hot core, a shockwave + hex ring on the ground,
|
||
// rising motes; while active a slowly turning hex with a soft glow under the unit (+ a few motes)
|
||
// blasts explosions (fireball, flash, shockwave + coloured ground ring, sparks, smoke; heavy ones add debris
|
||
// and a scorch mark) for blast fx kinds and shell impacts
|
||
// bombard 蕾缪安 S3: fx 'lock' keeps a reticle on the locked enemy until the 'bombard' of the shell fired at it
|
||
// (or LOCK_T game s after the shooter's last lock / shell; the S2 aim lock until the snipe's 'crit'); 'bombardShell' = a shell fired now that
|
||
// lands on the spot after `t` game s — a launch streak leaves the shooter upwards and the shell drops out
|
||
// of the sky onto the spot (a long flight climbs out of her first), a closing warning ring marks the spot
|
||
// meanwhile; 'bombard' is the big explosion at the impact
|
||
// deploy drop-in ring + pillar; death dissolve embers; crate splinters; element bursts; leak vignette;
|
||
// bond-layer glyph pops and bounty coins (screen space, near the top of the field)
|
||
// Sizes are in tiles × the camera's px per tile at the spot, so effects read alike at every resolution and zoom (3D
|
||
// board or 2D fallback: both project through the same camera). An fx anchored on a unit (extra.id) follows that
|
||
// unit's rendered position when the event happens on it, else it happens at the event's (x, y) (_where).
|
||
// Particles live in two ParticleContainers (additive / normal) sharing the FX atlas base texture, so the whole
|
||
// particle system costs two draw calls. Every pool has a cap; when full, the oldest entry is recycled. Particle,
|
||
// projectile and lock records are pooled (the per-frame emitters allocate nothing). Cosmetic extras — trails, muzzle
|
||
// flashes, afterimages, debris, scorch marks, aura motes — are skipped at quality 'low' and under heavy load
|
||
// (adaptive load level ≥ 2), and trails yield to bursts near the particle cap (SOFT_CAP).
|
||
|
||
//
|
||
// The bodies live in public/js/render/fx/*.js. Every name this file exported before the split is
|
||
// re-exported below, so existing imports keep working. speeds.js is imported first: its dynamic
|
||
// import('/sim/constants.js') is the module's one init side effect, as it was at the top of this file.
