IdleOn Blunder Bench

Calculators for Legends of IdleOn, all in one place. Import your IdleonToolbox save once on the Account page and every tool uses it; everything runs in your browser and the save is never uploaded.

Live site: https://rokadrol-haufi.github.io/IdleOn-Blunder-Bench/

Page	What it does
Account	Import your save (file, drop or paste) once for every tool, see your characters, and pick the Light / Dark / Auto theme.
Sampling and Gear Companion	3D Printer samples: compares your Mining, Chopping, Catching and Fishing efficiency with the top public samplers, source by source, with best-in-slot setups.
Stamp Upgrade Planner	Which stamp upgrades fit in a character's inventory, with Gilded Stamps and Hydrogen, sorted by how close to the carry cap they are.

Layout

index.html              landing page
account/                the Account page: the one place to import a save, plus the theme switch
assets/theme.css        shared "Arcade" theme: color tokens (light and dark), fonts, top bar, panels, buttons
assets/site.js          shared script: applies the theme, draws the top bar, stores the save (IndexedDB) and tool caches
assets/classes/         class icons for the Account page
sampling-gear-companion/      index.html, its sources (src/), data snapshot (data/) and build scripts
stamp-planner/          index.html, engine.js, sources (src/) and build scripts

Each tool is one page that loads assets/theme.css and assets/site.js. To rebuild one after a game update:

sampling-gear-companion/scripts/build.sh   # bundles IdleonToolbox + src/kimgap, assembles index.html
stamp-planner/scripts/build.sh             # bundles engine.js, assembles index.html

Both build scripts need Node 20+, Python 3 and git, and clone IdleonToolbox into the tool's .build/ folder.

Sampling and Gear Companion data

sampling-gear-companion/data/bench*.json is a snapshot of the five best public samplers per printer item from the IdleonToolbox leaderboards (efficiency breakdown leaves, statue, monument, vial and meal details, and the inputs behind each source). bis.json holds the best-in-slot boards and icons.json the row icons; both can be regenerated with REBUILD_IMAGES=1 scripts/build.sh.

Adding a tool

1. Put it in its own folder with an index.html that loads the shared files in <head> and has the bar as the first thing in <body>:

   <link rel="stylesheet" href="../assets/theme.css">
   <script src="../assets/site.js" data-page="mytool"></script>
   …
   <nav id="site-bar"></nav>
   

2. Read the save with await IdleonTools.account.getSave() ({id, text, label, lastUpdated, …} or null), and re-run when IdleonTools.account.onChange(fn) fires. Cache slow results with IdleonTools.cache.get/set('mytool', save.id, version, value). Never add an import box; link to ../account/ instead.
3. Add it to PAGES in assets/site.js (the top bar), add a card to the landing page and a row to the table above.
