Diamond Dynasty Lab

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a playable browser game titled “Diamond Dynasty Lab,” an original/licensed-safe baseball franchise and card-collection prototype. Use a dark navy, neon sports-interface aesthetic with translucent glass panels, rounded borders, cyan/green/purple/gold accents, bold condensed headings, and a responsive full-screen layout. Do not use MLB trademarks, real player names, real team logos, or player photographs; use generic/original names, a simple “DD” logo, placeholder initials, and a generic stadium.

Behind the interface, render a low-poly 3D baseball field using Three.js or an equivalent 3D layer: bright green circular outfield, brown four-sided dirt infield, pitcher’s mound, white home plate and three bases, white foul lines, dark blue-gray stadium seating blocks, a generic dark scoreboard, fog, and a dark navy sky/background. Use a perspective camera looking toward the mound/home plate from behind the batter, with subtle slow camera sway. Show a white baseball near the mound and a wooden bat near home plate; animate the baseball traveling from the mound toward the plate during a pitch and add a small timing indicator in the HUD.

The game opens on the Play tab with a top glass header showing the DD logo, the small label “Original Baseball Franchise,” the title “Diamond Dynasty Lab,” and resource counters: coins (initially 4,200), gems (120), tickets/tokens (40), and Fans (12,840). Add a horizontal glass navigation bar with functional tabs: Play, Cards, Packs, Franchise, Market, Events, and API.

Play tab: show a baseball scorebug with COM vs the customizable team name (initially “Velocity Club,” displayed as a short home label such as YOU), away/home runs, inning and half-inning, outs, and count. The initial game state is inning 1, bottom half, 0 outs, 0-0 count, empty bases, and 0-0 runs. Include an At Bat glass panel containing the current batter’s generated card, a horizontal timing meter with a moving needle and a highlighted perfect zone, a large “Tap / Click to Swing” button, and a readout explaining timing. Clicking/tapping the swing button or pressing Space starts a pitch if none is incoming, then resolves the at-bat according to timing. If the pitch is incoming, compare the input time to an ideal swing time and label the outcome PERFECT, EARLY GOOD, LATE GOOD, EARLY, LATE, or MISSED. Use batter attributes (contact, power, vision, clutch, speed, fielding, arm) and overall rating to influence strikeouts, outs, singles, doubles, triples, walks, and home runs. Perfect timing should improve hard contact and home-run odds; very poor timing should produce a strike. After resolution, automatically begin another pitch after a short delay. Display the outcome and coin reward in a toast/readout.

Beside the batting panel, add a Pitch Calling panel. Offer selectable pitch types Fastball, Slider, Curveball, Changeup, and Sinker plus a 3-by-3 location grid. Highlight the selected pitch and zone. A “Throw Selected Pitch” button should resolve a computer-controlled at-bat using pitcher attributes such as velocity, control, break, stamina, and clutch, with the pitch type and zone affecting the result. Correctly maintain balls, strikes, outs, bases, runs, inning/half-inning transitions, and rewards. Three strikes cause a strikeout/out; four balls cause a walk; three outs switch half-inning, clear bases/count, and award 80 coins. Hits advance runners, score runs, award coins based on hit bases/runs, and award a token when runs score.

Cards tab: show a roster grid of generated baseball cards. Seed the roster with 10 cards spanning Common, Uncommon, Rare, Epic, and Legendary tiers, with original generated first/last names, positions including C, 1B, 2B, 3B, SS, LF, CF, RF, SP, and RP, set names such as Opening Day, Future Stars, Lightning, Vintage, Rookie Sensations, All-Star, Awards Series, Prime, and Milestone, overall ratings, levels, XP, placeholder-initial portraits, and attributes. Sort cards by overall. Make tier colors visible: Common pale gray, Uncommon green, Rare cyan, Epic purple, Legendary gold, Mythic red/pink, Immortal white. Selecting a card highlights it and shows detailed attributes and its skill (examples: Hot Streak, Late-Inning Clutch, Gap Finder, Paint Corners, Quick Hands, Stadium Boost). Include a “Train Selected Card” button costing 120 coins; training grants XP, and at 100 XP levels the card up and randomly increases its attributes, recalculating overall.

Packs tab: show a centered glass pack-opening stage with a glowing animated “DYNASTY PACK” card back and an “Open Pack — 500 Coins” button. Deduct 500 coins, animate the pack reveal, generate a new card, add it to the roster, select it, and display its name/tier/set/position. Use these pull probabilities: Common 54%, Uncommon 24%, Rare 12%, Epic 6%, Legendary 2.5%, Mythic 1%, Immortal 0.5%. Include subtle card fan/card placement sound effects if supported.

Franchise tab: show editable team name, chemistry initially 64, fan count, and a public-API-ready status. Include purchasable upgrades: Stadium, Clubhouse, Scouting, and Training Facility, each starting at level 1 and costing 650 coins times its current level. Stadium increases fans and home-field value; Clubhouse increases chemistry/clutch; Scouting improves draft/pack odds; Training improves XP per game. Deduct coins and show a status message when upgraded or when funds are insufficient.

Market tab: show seven generated marketplace rows with original cards, tier badges, type (Buy Now, Auction, or Trade Offer), position, set, overall, and prices in the approximate 350–3800 coin range. A purchase button deducts coins, adds the card to the roster, and removes the listing. Beside it show collection progress rows such as Opening Day Set, Speed + Defense Club, Signature Series, and Team Collection with progress/targets and rewards like Rare Pack, Stadium Upgrade, Exclusive Card, and 1500 Coins.

Events tab: show generated live-content event rows including a date-based Daily Derby (Home Run Derby; reward Tokens + XP; requirement Hit 3 perfect swings), Weekend Chemistry Cup (Club Tournament; Club Tokens; Win 5 innings), Rookie Sensations Draft (Draft Mode; Prospect Pack; Build a 12-card squad), and Salary Cap Showdown (Fantasy Tournament; Gems; Stay under 850 OVR). Show a Ranked Seasons panel initially at Bronze division, rating 412, record 3-1, and explanatory planned ranks from Bronze through Legend. These are front-end prototype displays but should be navigable and functional as screens.

API tab: show a “Production Architecture Blueprint” informational panel describing the legal-safe placeholder image/logo strategy, a future React/TypeScript/Tailwind frontend and Node/Express backend, API concepts for players/cards/packs/franchise/market/events/ranked/clubs, database entities for users, franchises, cards, inventories, packs, collections, events, and transactions, approved public baseball data adapters, and economy guardrails. Keep all content original and clearly generic. Make all major navigation, swing, pitch, pack, train, purchase, upgrade, team-name, pitch-type, and zone controls work with pointer/touch input and keyboard Space for swinging.
