Noobisoft Monorepo — Web3 Game Demos and Services

This monorepo contains two playable browser games showcasing a cross‑game NFT concept, plus a supporting service for CID/metadata management. The goal is to demonstrate how player achievements and items can be represented as on-chain assets and reused across games.

Live Demos

• Dino: https://dino.open-elements.cloud/
• Pixel Racer: https://racer.open-elements.cloud/

You can open these links directly to test the games in your browser. Wallet connection and on‑chain flows are available where applicable.

Projects

Dino — Blockchain‑Backed Pixel Runner

An endless runner that integrates Hedera wallet flows. When players beat their high score, the app can mint and transfer a theme NFT to their account. Includes guidance for wallet connection (HashPack), testnet HBAR faucet, token association, and verifying NFTs via mirror node APIs.

• Tech: Vite, JS, Hedera wallet flows
• Play online: https://dino.open-elements.cloud/
• Local quick start:
  • cd dino && npm install
  • npm run dev (development)
  • npm run build then serve dist/ (production)

Core capabilities distilled from the project README:

• Wallet connect (HashPack extension/mobile)
• Testnet setup and faucet link
• Token association prompts and flows
• High‑score NFT minting concept and backend notes
• Mirror node endpoints to verify token associations and NFTs

Pixel Racer — Retro Arcade Racer (Web3‑Ready)

A 3‑lane racer built with Next.js 15 and React 19. Features smooth movement, jumping, progressive speed, retro sounds generated via Web Audio API, mobile controls, and a leaderboard UI. Designed with clear modular architecture and placeholders to integrate wallet, NFT car skins, and on‑chain leaderboard.

• Tech: Next.js 15, React 19, Canvas API, Web Audio API
• Play online: https://racer.open-elements.cloud/
• Local quick start:
  • cd pixel-racer && npm install
  • npm run dev (development)
  • npm run build && npm run start (production)
  • npm run lint (checks)

Highlights from the project README:

• Progressive difficulty (1.0x → 2.5x)
• Programmatic chiptune sound effects
• Clean, modular component and game‑loop structure
• Web3 integration targets: wallet connect, NFT car skins, on‑chain leaderboard

Nobi Service — CID Management Service

A TypeScript/Node service that manages and distributes unique CIDs/metadata from a predefined pool. It guarantees one‑time issuance with persistence across restarts and exposes REST endpoints for allocation, stats, and health checks. Useful for coordinating NFT metadata or cross‑game asset distribution.

• Tech: TypeScript, Node.js, Express (ES modules)
• Local quick start:
  • cd nobi-service && npm install
  • npm run dev (TypeScript via tsx)
  • npm start (build + run)
  • Endpoints: /api/cid, /api/stats, /health
• Data files: data/available_cids.json, data/used_cids.json

Cross‑Game NFT Concept (High‑Level)

1. Game events (e.g., new high score) trigger minting or assignment of an NFT or metadata entry.
2. Ownership is tied to a player wallet; token association may be required (Hedera).
3. Other games read wallet holdings/metadata to unlock themed skins, visuals, or progression.
4. A small backend (e.g., CID management) coordinates unique metadata/CIDs across apps.

Local Development

Run projects independently from their directories:

• Dino

  • cd dino && npm install
  • npm run dev (dev) or npm run build and serve dist/ (prod)

• Pixel Racer

  • cd pixel-racer && npm install
  • npm run dev (dev), npm run build && npm run start (prod)

• Nobi Service

  • cd nobi-service && npm install
  • npm run dev (dev), npm start (prod)

Notes

• Use the live links to play and validate flows:
  • Dino: https://dino.open-elements.cloud/
  • Pixel Racer: https://racer.open-elements.cloud/
• Wallet connection is required for certain features (e.g., token association, mint) in Dino.
• For Hedera Testnet, obtain HBAR from https://portal.hedera.com/faucet.
