FRIENDLY ROBOTS!

FRIENDLY ROBOTS!

The live site is the static files at the repository root. Vercel serves them as-is (no build command, framework null). index.html is the homepage.

EDITING index.html is the page, including metadata and JSON-LD. styles.css, catalog.js, app.js, and friend.js are the other editable sources. assets/robotown.webp is the hero image. assets/robotown.jpg is the fallback. assets/og.jpg is the 1200x630 share image.

After changing a book in catalog.js, run: node build.cjs That refreshes the Book JSON-LD in index.html and checks links, categories, and required copy. Commit the updated index.html. Vercel does not run the script.

AMAZON Product and author-store links use tag=stashandset-20, the Associates tracking ID confirmed from reviews.bfloore.online. The page discloses that relationship. Book JSON-LD url stays the clean dp URL. offers.url carries the tag.

NOT UPLOADED .vercelignore keeps build.cjs and this README off the public site.

GAME (/play) Rex Runs RoboTown lives in play/ and loads only on /play, so the homepage stays light. play/engine.js holds the rules: speeds, level lengths, time limits, the shield and the obstacle layouts. play/game.js draws everything and handles controls and screens. Tuning lives at the top of engine.js: ALLOWED_BUMPS (bumps each board allows before the clock runs out), BONK (how long a bump stuns Rex), PHYS (jump height and float), PLATFORM heights, and POWERS / POWER_ORDER (power-ups, earned one per board from board 2). After changing engine.js, run: node play/test-engine.cjs That plays every level hundreds of times and fails if a level cannot be cleared without bumps, or if a player who never presses anything can still finish. The prize coloring pages are b. floore's Rex and Billy art in play/prizes/pages/ (300 dpi grayscale PNGs plus small thumbnails), with each pack also as a PDF in play/prizes/. Board 5 unlocks pack 1, board 10 unlocks pack 2. play/prizes/prizes.json says which pages go in which pack, in what order, and after which board; the game reads it, so no code changes are needed. To add new pages: python3 play/prizes/make_prizes.py --add That makes the next numbered pages and thumbnails. Then put the new page numbers in prizes.json (or add a pack with its own "after" board and "pdf" name) and rebuild the PDFs with: python3 play/prizes/make_prizes.py To swap in an updated picture for an existing page, keeping its number: python3 play/prizes/make_prizes.py --set Progress and prizes are saved in the player's own browser (localStorage). The prize gate is client-side, so anyone who knows the file address can download the pages.
