From c1b8292f92f5f07581342babe84ba0ac8a1dcf82 Mon Sep 17 00:00:00 2001 From: sganggs Date: Mon, 5 Oct 2026 17:13:07 +0800 Subject: [PATCH] feedback5 R5: split the battle effect system into modules 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. --- public/js/render/fx.js | 2234 +--------------------------- public/js/render/fx/arrivals.js | 120 ++ public/js/render/fx/beams.js | 172 +++ public/js/render/fx/camera.js | 28 + public/js/render/fx/fonts.js | 21 + public/js/render/fx/kinds.js | 145 ++ public/js/render/fx/limits.js | 13 + public/js/render/fx/locks.js | 104 ++ public/js/render/fx/numbers.js | 368 +++++ public/js/render/fx/particles.js | 139 ++ public/js/render/fx/projectiles.js | 464 ++++++ public/js/render/fx/rings.js | 136 ++ public/js/render/fx/simfx.js | 298 ++++ public/js/render/fx/speeds.js | 38 + public/js/render/fx/system.js | 174 +++ public/js/render/fx/zones.js | 155 ++ 16 files changed, 2385 insertions(+), 2224 deletions(-) create mode 100644 public/js/render/fx/arrivals.js create mode 100644 public/js/render/fx/beams.js create mode 100644 public/js/render/fx/camera.js create mode 100644 public/js/render/fx/fonts.js create mode 100644 public/js/render/fx/kinds.js create mode 100644 public/js/render/fx/limits.js create mode 100644 public/js/render/fx/locks.js create mode 100644 public/js/render/fx/numbers.js create mode 100644 public/js/render/fx/particles.js create mode 100644 public/js/render/fx/projectiles.js create mode 100644 public/js/render/fx/rings.js create mode 100644 public/js/render/fx/simfx.js create mode 100644 public/js/render/fx/speeds.js create mode 100644 public/js/render/fx/system.js create mode 100644 public/js/render/fx/zones.js diff --git a/public/js/render/fx.js b/public/js/render/fx.js index 14034cb4..9e0c9650 100644 --- a/public/js/render/fx.js +++ b/public/js/render/fx.js @@ -33,2227 +33,13 @@ // 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). -import { fxAtlas } from './textures.js'; -import { DMG_STYLE, dmgStyleKey, HIT_TINT, PROJ, COLORS } from './style.js'; - -/** - * The sim's projectile speeds (server/sim/constants.js PROJECTILE_SPEEDS — pure data, served read-only at - * /sim/constants.js with the rest of the client-side sim, DESIGN §14): a shot's visual flight ends when the sim lands it, - * i.e. with its damage number.
