Second, we’ll provide a detailed, step-by-step walkthrough for setting up the development environment, enabling you to get the game running locally, explore the codebase, and potentially make your first contribution. Whether you’re a seasoned developer, a student looking to learn, a game designer with ideas, or simply a basketball fan curious about game development, this guide aims to equip you with the knowledge needed to engage with the Basketball Bros project.

Part 1: Introduction to the Basketball Bros Project

1.1 What is Basketball Bros? The Core Concept

At its heart, Basketball Bros is envisioned as a fun, fast-paced, physics-based 2D basketball game with a retro aesthetic but modern sensibilities. Imagine the chaotic energy of classic arcade sports titles combined with smooth online multiplayer and deep customization options. The game focuses on 1v1 or 2v2 matches where players control quirky, customizable “Bros” with unique (and often humorous) abilities.

The gameplay emphasizes skill, timing, and clever use of physics. Players can dribble, shoot, pass, steal, block, and perform special moves. The ball’s trajectory, bounces, and interactions are governed by a 2D physics engine, leading to emergent and often unpredictable moments of gameplay brilliance (or hilarious failure). Matches are designed to be quick and engaging, perfect for short bursts of competitive fun or longer sessions with friends.

Unlike polished, closed-source commercial titles, Basketball Bros thrives on its open nature. It’s not just a game; it’s a platform for learning, experimentation, and community building. Hosted entirely on GitHub, its source code is freely available for anyone to inspect, modify, and contribute to.

1.2 The Vision and Philosophy: More Than Just a Game

The Basketball Bros project was initiated with several core goals in mind:

  1. Create a Genuinely Fun Game: The primary objective is to build an enjoyable and replayable basketball game that captures the excitement of the sport in a unique 2D format.
  2. Foster a Collaborative Community: To bring together developers, artists, designers, testers, and players who are passionate about basketball and game development. GitHub serves as the central hub for this collaboration.
  3. Provide Educational Value: The project aims to be a learning resource. By using common web technologies and clear coding practices (aspiringly!), it offers a practical example for those looking to understand game architecture, real-time networking, physics integration, and full-stack web development.
  4. Embrace Openness and Transparency: All development discussions, bug tracking, feature planning, and code changes happen publicly on GitHub. This transparency builds trust and encourages participation.
  5. Enable Customization and Modding: The architecture is designed (or aims to be designed) with extensibility in mind, allowing the community to easily create new characters, courts, abilities, game modes, and potentially even full conversions.
  6. Iterative Development: Following agile principles, the game evolves through small, incremental updates based on community feedback and contributions. There’s no pressure for a “perfect” release, but rather a continuous journey of improvement.

The underlying philosophy is that collaborative, open development can lead to richer, more diverse, and more resilient projects. It harnesses the collective intelligence and creativity of the community, allowing the game to grow in directions perhaps unforeseen by the initial creators.

1.3 Key Features (Current & Planned)

Basketball Bros boasts a growing list of features, driven by its ongoing development:

  • Physics-Based Gameplay: Utilizes a 2D physics engine (like Matter.js or Box2D) for realistic (and sometimes exaggerated) ball movement, collisions, and character interactions. Dunks, blocks, and rebounds feel dynamic and impactful.
  • Real-time Online Multiplayer: The core experience is built around online matches. Leveraging WebSockets (via libraries like Socket.IO), the game aims for low-latency synchronization between players for a smooth competitive experience. Includes basic matchmaking and room creation.
  • Character Customization: Players can personalize their “Bros” with different heads, bodies, accessories, and color schemes. New cosmetic items are planned as community contributions.
  • Unique Bro Abilities (Planned): Future plans include giving different Bros unique skills – perhaps a super jump, a power shot, a temporary speed boost, or a tricky dribble move – adding a layer of strategic depth.
  • Multiple Game Modes (Planned): While currently focused on 1v1 and 2v2 exhibition matches, future modes could include tournaments, a ranked ladder, practice drills, or even cooperative challenges.
  • Variety of Courts: Different court environments with potentially unique physical properties or visual themes.
  • Cross-Platform Accessibility: Primarily targets modern web browsers (desktop and potentially mobile) for maximum accessibility, requiring no installation for players. Desktop builds using frameworks like Electron might also be considered.
  • Simple, Retro-Inspired Art Style: Uses a clean, pixel-art or vector-art style that is visually appealing, performs well, and is relatively easy for community artists to contribute to.
  • Spectator Mode (Planned): Ability for users to watch ongoing matches.
  • Basic AI Opponents: Includes simple AI for offline practice or filling empty player slots.

It’s crucial to remember that as an open-source project, the feature set is constantly evolving based on contributor efforts and community priorities.

1.4 Target Audience: Who is Basketball Bros For?

The project appeals to a diverse group:

  1. Players: Anyone looking for a fun, free, accessible online basketball game with a unique charm. Especially those who enjoy arcade sports titles and competitive multiplayer.
  2. Aspiring Game Developers: Students or hobbyists interested in learning how a complete game is built, particularly using web technologies. The codebase serves as a practical, dissectible example.
  3. Web Developers: Frontend and backend developers interested in real-time applications, WebSocket communication, game loops in JavaScript/TypeScript, or contributing to a fun side project.
  4. Game Designers: Individuals with ideas for new gameplay mechanics, character abilities, game modes, or balancing adjustments who can propose and potentially help implement these changes.
  5. Artists and Musicians: 2D artists, animators, UI designers, sound effect creators, and composers looking to contribute assets to a game project and build their portfolio.
  6. Open Source Enthusiasts: People passionate about the open-source movement who want to contribute to a community-driven project, regardless of their specific technical skills (documentation, testing, community management are also valuable).
  7. Modders: Players and developers interested in creating custom content (characters, courts, etc.) once the modding infrastructure is more mature.

1.5 Why Open Source? The Power of Collaboration

Choosing to develop Basketball Bros as an open-source project on GitHub wasn’t an arbitrary decision. It offers significant advantages:

  • Transparency: Anyone can see the code, the issues being worked on, and the direction of the project. This fosters trust and accountability.
  • Collaboration: It allows developers from around the world to contribute their skills and ideas, potentially leading to faster development and more innovative features than a small, closed team could achieve.
  • Learning Opportunity: It provides a real-world codebase for others to learn from. Contributors gain experience working on a larger project, using version control, and collaborating with others.
  • Code Quality: Public scrutiny can lead to higher code quality. Peer reviews through pull requests help catch bugs, suggest improvements, and enforce coding standards.
  • Community Ownership: Contributors and regular players often feel a sense of ownership and pride in the project, leading to a more engaged and supportive community.
  • Longevity: Even if the original maintainers step away, the open-source nature allows the community to fork the project and continue its development.
  • Cost: Development relies on volunteer effort, and hosting on GitHub is free for open-source projects. This makes ambitious projects feasible without significant financial backing.

The license chosen (likely MIT or a similar permissive license) ensures that the code remains free to use, modify, and distribute, while protecting contributors.

1.6 Technology Stack Deep Dive

Understanding the technologies used is crucial for setting up the project and contributing effectively. Basketball Bros leverages a modern web-centric stack:

  • Frontend (Client-Side):

    • Language: Primarily TypeScript. Chosen for its static typing, which improves code maintainability, reduces runtime errors, and enhances developer productivity, especially in larger projects. It transpiles down to JavaScript.
    • Rendering: HTML5 Canvas API. The game graphics are drawn directly onto an HTML <canvas> element using the Canvas 2D context. This provides fine-grained control over rendering and performance, suitable for a 2D game. Alternatively, a lightweight library like PixiJS or Phaser might be used or considered for managing sprites, animations, and rendering optimizations. (For this guide, let’s assume a custom Canvas renderer for maximum detail description, but acknowledge libraries are alternatives).
    • Framework/Structure: While not relying on a heavy framework like React or Angular for the game rendering itself, it might use a simple structure for UI elements (menus, scoreboards) or state management.
    • Build Tool: Vite or Webpack. Used to bundle TypeScript/JavaScript modules, process assets (images, audio), handle transpilation, and provide a development server with features like Hot Module Replacement (HMR) for faster development cycles.

  • Backend (Server-Side):

    • Runtime Environment: Node.js. Chosen for its asynchronous, event-driven architecture, which is well-suited for handling many concurrent WebSocket connections required for real-time multiplayer games. Its large ecosystem (npm) is also a major benefit.
    • Language: TypeScript. Used consistently with the frontend for type safety and code sharing possibilities (e.g., shared game logic or data structures).
    • Framework: Express.js (or potentially Koa.js/Fastify). A minimal and flexible Node.js web application framework used to handle HTTP requests (e.g., serving the game client, handling basic API calls) and integrate the WebSocket server.
    • Real-time Communication: Socket.IO (or potentially the native ws library). A library that enables real-time, bidirectional, event-based communication between the client and server over WebSockets. It handles connection management, fallback mechanisms, and room broadcasting, crucial for synchronizing game state across multiple players.
    • Physics Engine (Server-Side): The physics calculations might run authoritatively on the server to prevent cheating and ensure consistency, especially for critical interactions. A JavaScript version of a physics engine like Matter.js or a WebAssembly port of Box2D could be used here as well.

  • Physics Engine (Client & Server):

    • Library: Matter.js (or Box2D-WASM). A JavaScript 2D rigid body physics engine. Responsible for simulating collisions, gravity, friction, and restitution for the ball and players. Running physics consistently on both client (for prediction) and server (for authority) is a common pattern.

  • Version Control & Hosting:

    • Git: The standard for distributed version control, tracking changes to the codebase.
    • GitHub: The platform hosting the Git repository, facilitating collaboration through features like pull requests, issue tracking, project boards, and actions (for CI/CD).

  • Package Management:

    • npm (Node Package Manager) or Yarn. Used to manage project dependencies (libraries like Express, Socket.IO, Matter.js, TypeScript, Vite/Webpack) for both the frontend and backend.

This stack represents a common and effective approach for building web-based multiplayer games, balancing performance, developer experience, and accessibility.

1.7 Project Structure Overview

A typical Basketball Bros project repository might look something like this (simplified):

Understanding this structure helps navigate the codebase and locate relevant files when developing or debugging. Note that the exact structure might vary, especially if using a monorepo tool like Lerna, Nx, or Turborepo to manage the client and server packages.

Part 2: Setting Up Your Development Environment

Now that you have a good understanding of what Basketball Bros is, let’s get our hands dirty and set up the project locally. This will allow you to run the game, experiment with the code, and prepare for making contributions.

This guide assumes a basic familiarity with the command line or terminal.

2.1 Prerequisites: Tools of the Trade

Before cloning the repository, you need several essential tools installed on your system.

  1. Git:

    • What it is: A distributed version control system crucial for downloading the project code (cloning) and managing changes.
    • Check Installation: Open your terminal or command prompt and type git --version. If it returns a version number (e.g., git version 2.34.1), you’re good to go.
    • Installation:
      • Windows: Download the official installer from git-scm.com. Alternatively, consider using package managers like Chocolatey (choco install git) or Winget (winget install --id Git.Git -e --source winget). During installation, using the recommended settings is usually fine. Ensure Git is added to your system’s PATH.
      • macOS: Git often comes pre-installed. If not, or if you want a newer version, the easiest way is using Homebrew: brew install git. Alternatively, installing Xcode Command Line Tools (xcode-select --install) also includes Git.
      • Linux (Debian/Ubuntu): sudo apt update && sudo apt install git
      • Linux (Fedora): sudo dnf install git

  2. Node.js and npm (or Yarn):

    • What they are: Node.js is the JavaScript runtime environment used for the backend server and build tools. npm (Node Package Manager) comes bundled with Node.js and is used to install project dependencies. Yarn is an alternative package manager offering similar functionality, sometimes preferred for its speed or lockfile handling. The project’s README.md should specify whether npm or Yarn is preferred/required. We’ll primarily use npm commands here, but Yarn equivalents are usually similar (yarn install instead of npm install, yarn build instead of npm run build, etc.).
    • Recommended Version: Check the project’s README.md or package.json (under the engines field) for specific Node.js version requirements (e.g., LTS – Long Term Support version). Using a Node Version Manager like nvm (macOS/Linux) or nvm-windows (Windows) is highly recommended to easily switch between Node.js versions.
    • Check Installation: Open your terminal and type node -v and npm -v. If they return version numbers, they are installed.
    • Installation:
      • All Platforms: The recommended way is often via a version manager:
        • nvm (macOS/Linux): Follow instructions at nvm.sh. Then install a specific version: nvm install --lts (for the latest LTS) or nvm install 18 (for version 18). Use nvm use lts or nvm use 18 to activate it.
        • nvm-windows (Windows): Follow instructions at nvm-windows. Then use nvm install lts and nvm use <version>.
      • Direct Download: Alternatively, download installers from the official Node.js website. Choose the LTS version unless the project specifies otherwise.

  3. Code Editor / Integrated Development Environment (IDE):

    • What it is: A text editor designed for coding, offering features like syntax highlighting, code completion, debugging tools, and Git integration.
    • Recommendations:
      • Visual Studio Code (VS Code): Free, highly popular, and versatile with a vast extension marketplace. Excellent TypeScript support and terminal integration. Highly recommended for this tech stack.
      • WebStorm: A powerful paid IDE from JetBrains, specifically focused on JavaScript/TypeScript development.
      • Sublime Text / Atom: Other capable text editors, potentially requiring more manual configuration for optimal TypeScript/Node.js development.
    • Installation: Download and install from their respective websites. For VS Code, consider installing extensions like ESLint, Prettier - Code formatter, and potentially Debugger for Node.js.

  4. Web Browser:

    • What it is: Needed to run and test the client-side part of the game.
    • Recommendations: Modern browsers like Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari. Developer tools within these browsers (accessible usually by pressing F12) are essential for debugging frontend code.

With these prerequisites installed, your machine is ready to handle the Basketball Bros project.

2.2 Getting the Source Code: Cloning the Repository

The project’s code lives in a Git repository on GitHub. You need to create a local copy on your machine.

  1. Find the Repository URL: Go to the main page of the Basketball Bros GitHub repository (the URL will be something like https://github.com/YourUsernameOrOrg/basketball-bros). Click the green “<> Code” button. Make sure “HTTPS” is selected (unless you have SSH keys set up) and copy the URL provided. It will look like https://github.com/YourUsernameOrOrg/basketball-bros.git.

  2. Choose a Location: Decide where you want to store the project files on your computer. A dedicated projects or dev folder in your home directory is common.

  3. Clone the Repository: Open your terminal or command prompt, navigate to your chosen parent directory using the cd command (e.g., cd ~/dev), and then run the git clone command, replacing the URL with the one you copied:

    bash
    git clone https://github.com/YourUsernameOrOrg/basketball-bros.git

    • What happens: Git contacts GitHub, downloads the entire project history and files into a new folder named basketball-bros inside your current directory.

  4. Navigate into the Project Directory: Once cloning is complete, change into the newly created project folder:

    bash
    cd basketball-bros

    You are now inside the project’s root directory. All subsequent commands should be run from here unless otherwise specified.

2.3 Understanding the package.json File

Before installing dependencies, it’s helpful to look at the package.json file in the project root (or potentially separate ones in client/ and server/ if it’s not a monorepo). This JSON file is fundamental to Node.js projects. Key sections include:

  • name, version, description: Basic project metadata.
  • main or module: Specifies the entry point of the project (more relevant for libraries, sometimes used for server entry point).
  • scripts: Defines command-line shortcuts for common tasks. You’ll use these extensively. Examples:
    • "start": Typically runs the production build of the server.
    • "dev" or "develop": Usually starts development servers (frontend and/or backend) with features like auto-reloading.
    • "build": Compiles TypeScript, bundles code, and prepares assets for deployment.
    • "test": Runs automated tests.
    • "lint": Checks code for style and potential errors using tools like ESLint.
    • "format": Automatically formats code using tools like Prettier.
  • dependencies: Lists packages required for the application to run in production (e.g., express, socket.io, matter-js).
  • devDependencies: Lists packages needed only for development and building (e.g., typescript, vite, webpack, eslint, prettier, testing libraries, type definitions like @types/node).
  • engines: Specifies the recommended Node.js and npm versions (optional but good practice).

Reviewing the scripts section gives you a quick overview of how to build, run, and test the project.

2.4 Installing Dependencies: Gathering the Building Blocks

The source code you cloned doesn’t include the external libraries (dependencies) it relies on. You need to download and install them using the package manager defined by the project (npm or Yarn).

  1. Check for Specific Instructions: Look in the README.md for any specific instructions regarding dependency installation. Does it require Yarn? Does it use a monorepo structure requiring installation from the root?

  2. Run Installation Command: Assuming npm is used and you’re in the project’s root directory:

    bash
    npm install

    • If Yarn is specified:
      bash
      yarn install
    • If it’s a monorepo (check README): Sometimes you run the command at the root, and it installs dependencies for all packages (client, server, shared). Other times, you might need to cd into specific directories (cd client && npm install, then cd ../server && npm install). Follow the project’s documentation.

  3. What happens:

    • npm (or Yarn) reads the package.json file.
    • It downloads the specified versions of all packages listed in dependencies and devDependencies from the npm registry (or Yarn registry).
    • It places the downloaded packages into a folder named node_modules. This folder can become quite large and is usually listed in .gitignore so it’s not committed to version control.
    • It creates or updates a package-lock.json (npm) or yarn.lock (Yarn) file. This file locks down the exact versions of all installed dependencies and their sub-dependencies, ensuring that anyone else setting up the project gets the exact same versions, leading to more reproducible builds. You should commit this lock file to Git.

This step might take a few minutes, depending on the number of dependencies and your internet connection. Watch for any ERR! messages in the output, which might indicate problems (e.g., incompatible Node.js version, network issues, missing system dependencies for certain packages).

2.5 Configuration: Setting Up Your Environment

Many applications require configuration settings that might differ between development, testing, and production environments, or contain sensitive information (like API keys, database credentials – though likely simpler for this game). These are often managed using environment variables or configuration files.

  1. Look for .env.example or similar: Check the project root for a file named .env.example, config.example.json, or similar. This file serves as a template for the actual configuration file you need to create.

  2. Create Your Configuration File: Copy the example file to the name the application expects. Typically, this involves environment variables loaded via a .env file (using a library like dotenv).

    bash
    cp .env.example .env

    • Important: The actual .env file (or other config files containing secrets) should be listed in your .gitignore file to prevent accidentally committing sensitive information to the repository.

  3. Edit the Configuration File: Open the newly created .env (or equivalent) file in your code editor. Review the variables defined inside. For local development, the default values provided in the .env.example are often sufficient. Common variables might include:

    • PORT: The port number the backend server should listen on (e.g., 3000 or 8080).
    • HOST: The network interface the server should bind to (often localhost or 0.0.0.0).
    • LOG_LEVEL: Controls the verbosity of logging (e.g., debug, info, warn).
    • PHYSICS_STEP_RATE: How often the server physics simulation updates.
    • DATABASE_URL (Less likely for this type of game, but possible for user accounts).
    • API_KEYS (If integrating external services).

    Adjust these values if necessary (e.g., if the default PORT is already in use on your machine).

  4. Understand How Config is Loaded: Briefly check the server-side code (likely near server.ts or a dedicated config module) to see how these environment variables or config files are loaded and used by the application. This helps in troubleshooting later.

2.6 Building the Project: Transpiling and Bundling

Since the project uses TypeScript, the .ts files need to be transpiled into JavaScript (.js) that Node.js and browsers can understand. Additionally, the frontend code and assets often need to be bundled for efficiency.

  1. Check package.json for Build Scripts: Look for scripts like "build", "build:client", "build:server".

  2. Run the Build Script: Execute the appropriate build command from the project root (or specific directories if required). A common command is:

    bash
    npm run build

    • If using Yarn:
      bash
      yarn build

  3. What happens:

    • The TypeScript compiler (tsc) might be invoked directly or via the build tool (Vite/Webpack).
    • It reads tsconfig.json (and potentially tsconfig.base.json, client/tsconfig.json, server/tsconfig.json) for compiler options.
    • It type-checks the TypeScript code. Errors here will stop the build.
    • It transpiles .ts files into .js files, usually placing them in a distribution folder (e.g., dist/, build/, out/). Separate folders might be used for client and server builds (dist/client, dist/server).
    • For the client, Vite/Webpack bundles the JavaScript code (following imports), potentially minifies it, processes CSS, copies static assets (images, fonts) from the public or assets directory, and generates the final index.html and associated JavaScript bundles in the client’s output directory.
    • For the server, the build process might just involve transpiling TypeScript to JavaScript.

The build output (dist or similar folder) contains the executable code and assets ready to be run. Like node_modules, this build output directory is typically included in .gitignore.

2.7 Running the Project Locally: Bringing Basketball Bros to Life!

With dependencies installed and the project built (or using a development server that handles this on the fly), you can now run the game locally. Usually, this involves starting the backend server and then accessing the frontend client in your browser.

  1. Check package.json for Run Scripts: Look for scripts like "start", "dev", "serve", "start:server", "dev:client". The "dev" script is often the most convenient for development as it usually includes auto-reloading on code changes.

  2. Start the Development Server(s): The easiest way is often a single command if configured in the root package.json (perhaps using a tool like concurrently to run multiple commands):

    bash
    npm run dev

    • If using Yarn:
      bash
      yarn dev
    • Separate Commands: If there isn’t a combined dev script, you might need to run the backend and frontend development servers separately, potentially in different terminal windows/tabs:
      • Terminal 1 (Backend): cd server && npm run dev (or npm start if no dev script)
      • Terminal 2 (Frontend): cd client && npm run dev (Vite/Webpack dev server)

  3. What happens (with dev scripts):

    • Backend: A tool like nodemon or ts-node-dev might be used to run the server (server.ts). It watches for file changes in the server/src directory and automatically restarts the Node.js server when changes are detected. It uses ts-node or similar to execute TypeScript directly without needing a separate build step during development.
    • Frontend: Vite or Webpack’s development server starts. It serves the client files (often from memory). It watches for changes in the client/src directory. When changes are detected, it quickly rebuilds only the necessary parts (HMR – Hot Module Replacement) and injects the changes into the running application in the browser, often without a full page reload. This drastically speeds up frontend development.

  4. Observe the Terminal Output: The terminals where you ran the commands will show log output. Look for messages indicating:

    • The server has started successfully and is listening on a specific port (e.g., Server listening on http://localhost:3000).
    • The client development server is running and accessible at a different URL (e.g., Vite might run on http://localhost:5173). The backend server might be configured to proxy requests from the client’s port to its own port to avoid CORS issues during development.

  5. Access the Game: Open your web browser and navigate to the URL provided by the frontend development server (e.g., http://localhost:5173 or whatever URL was logged in the terminal).

    • You should see the Basketball Bros game loading screen, menu, or initial state.
    • The client running in the browser will attempt to connect to the backend WebSocket server (running on its port, e.g., 3000, potentially proxied). Check the browser’s developer console (F12) and the server terminal output for connection success messages or errors.

  6. Test Basic Functionality: Try starting a game (perhaps against AI if available, or open a second browser tab/window to the same URL to simulate another player if 1v1 is implemented). Test basic movement and actions.

Congratulations! You now have a local development instance of Basketball Bros running. You can start exploring the code, making changes, and seeing them reflected (often automatically thanks to the dev servers).

2.8 Running Tests (Optional but Recommended)

Good open-source projects often include automated tests to ensure code quality and prevent regressions.

  1. Check package.json for Test Scripts: Look for a "test" script.

  2. Run Tests:

    bash
    npm test

    • If using Yarn:
      bash
      yarn test

  3. What happens: This command typically executes a test runner (like Jest, Mocha, Vitest) configured for the project. It will discover and run test files (often ending in .test.ts or .spec.ts) located in the tests/ directory or alongside the source code. The output will indicate how many tests passed or failed. Running tests after making changes is crucial before submitting contributions.

Part 3: Troubleshooting Common Setup Issues

While the setup process aims to be smooth, you might encounter hurdles. Here are some common issues and how to address them:

  1. Git Clone Fails:

    • Symptom: Error message during git clone.
    • Causes: Network issues, incorrect repository URL, Git not installed or not in PATH, firewall restrictions.
    • Solutions: Check internet connection, verify the URL copied from GitHub, ensure git --version works in the terminal, check firewall/proxy settings.

  2. npm install (or yarn install) Fails:

    • Symptom: Errors during dependency installation, often mentioning specific packages, permissions (EACCES), Python/Node-Gyp issues, or network timeouts.
    • Causes:
      • Incompatible Node.js/npm version (check project requirements vs. node -v). Use nvm to switch if needed.
      • Network issues or npm registry problems (check status.npmjs.org). Try again later or configure a proxy if needed (npm config set proxy ...).
      • Permissions errors: Avoid using sudo npm install. Fix permissions on your global/local node_modules folders if necessary, or reinstall Node.js/nvm correctly. On Linux/macOS, ensure correct ownership of installation directories.
      • Missing build tools (node-gyp errors): Some packages compile native addons and require Python, C++ compiler (like GCC, Clang, or MS Build Tools). Follow node-gyp installation instructions for your OS (often involves installing Python and build essentials/Visual Studio Build Tools).
      • Corrupt cache: Try clearing the cache (npm cache clean --force or yarn cache clean) and deleting node_modules and package-lock.json / yarn.lock, then run npm install again.
      • Conflicting package managers: If the project uses Yarn, ensure you use yarn install, not npm install, and vice-versa (especially regarding the lock file).

  3. Build Errors (npm run build):

    • Symptom: TypeScript errors (TS...), Webpack/Vite errors, module not found errors.
    • Causes: Syntax errors in your code (if you’ve made changes), incorrect TypeScript configuration (tsconfig.json), missing type definitions (@types/... packages might be missing from devDependencies), issues with build tool configuration (vite.config.ts, webpack.config.js).
    • Solutions: Carefully read the error messages – they usually point to the problematic file and line number. Ensure all devDependencies are installed correctly. Check tsconfig.json for correct paths and settings. If you recently pulled changes, ensure your dependencies are up-to-date (npm install).

  4. Server Fails to Start (npm run dev or npm start):

    • Symptom: Server crashes immediately, error messages like Port already in use, Cannot find module, environment variable errors.
    • Causes:
      • Port conflict: Another application is using the port defined in .env or config (e.g., 3000).
      • Missing .env file or incorrect variables: Ensure you copied .env.example to .env and the required variables are set.
      • Code errors: Runtime errors in the server-side JavaScript/TypeScript code.
      • Incomplete build: If using npm start which relies on built files, ensure npm run build completed successfully first. (npm run dev usually avoids this).
    • Solutions: Change the PORT in .env or stop the other application using the port (use tools like lsof -i :<port> on Linux/macOS or netstat -ano | findstr <port> on Windows to find the process). Check server logs for specific error messages. Ensure .env is present and correctly formatted.

  5. Client Fails to Load or Connect to Server:

    • Symptom: Browser shows a blank page, “Cannot GET /” error, “Connection refused” errors in the console, game doesn’t load assets, WebSocket connection fails.
    • Causes:
      • Frontend dev server not running or on a different port than expected.
      • Backend server not running.
      • Incorrect URL entered in the browser.
      • CORS (Cross-Origin Resource Sharing) issues: The browser prevents the client (e.g., on localhost:5173) from making requests to the server (e.g., on localhost:3000) unless configured correctly. Dev servers often handle this via proxy settings, but misconfiguration can cause problems.
      • WebSocket connection issues: Server not handling WebSocket upgrades, firewall blocking WebSocket ports, incorrect WebSocket URL used by the client.
    • Solutions: Ensure both backend and frontend dev servers are running. Verify the URLs and ports in the terminal output and browser. Check browser developer console (Network and Console tabs) for detailed errors (404s, CORS errors, WebSocket errors). Check the server configuration for CORS and WebSocket handling. Ensure firewalls aren’t blocking the ports.

  6. Git Issues (When Pulling Updates):

    • Symptom: Merge conflicts when running git pull.
    • Causes: You have made local changes to files that were also modified upstream (in the main repository).
    • Solutions: Commit or stash your local changes before pulling (git stash, git pull, git stash pop). If conflicts occur, Git will mark the conflicting sections in the files. Open these files in your editor, resolve the differences manually (choose which code version to keep or merge them), save the files, then use git add <resolved-file> and git commit to finalize the merge. Learning basic Git conflict resolution is essential for collaboration.

When facing issues, carefully read all error messages, check the project’s README.md and CONTRIBUTING.md for specific setup notes or troubleshooting tips, and don’t hesitate to search online for the error message or consult the project’s community channels (like GitHub Issues or Discord) if you’re stuck.

Part 4: Next Steps & Getting Involved

Now that you have Basketball Bros running locally, what’s next?

4.1 Exploring the Codebase

Take some time to familiarize yourself with the project structure (outlined in Part 1.7). Good starting points might be:

  • Client Entry Point: client/src/main.ts – See how the game is initialized.
  • Game Loop: Look for the core game loop logic (updating state, rendering) within the client/src/game/ directory.
  • Entity/Component System: How are players, the ball, and other game objects represented and managed?
  • Rendering: How is the game drawn to the Canvas? (client/src/game/rendering/)
  • Networking: Examine client/src/network/ and server/src/network/ to understand how client and server communicate game state via Socket.IO.
  • Server State Management: How does the server keep track of ongoing games and player states? (server/src/game/)
  • Physics Integration: Where and how is the physics engine (Matter.js/Box2D) used?

Use your code editor’s features (like “Go to Definition”, “Find Usages”) to navigate relationships between different parts of the code.

4.2 Making Your First Contribution

Contributing back to the project is a great way to learn and help the game grow.

  1. Find Something to Work On:

    • GitHub Issues: Check the repository’s “Issues” tab. Look for issues tagged good first issue, help wanted, or bug. These are often good starting points for new contributors.
    • Documentation: Improving documentation (README.md, CONTRIBUTING.md, code comments, setting up a wiki) is always valuable.
    • Bug Fixing: If you encountered a bug while playing or testing, try to debug it and fix it.
    • Minor Features: Implement a small, self-contained feature that has been discussed or requested.
    • Tests: Add unit or integration tests for existing code.

  2. Follow Contribution Guidelines: Read the CONTRIBUTING.md file carefully. It will outline the process for contributing, including:

    • Forking the Repository: Create your own copy of the repository on GitHub.
    • Creating a Branch: Make your changes on a new Git branch (git checkout -b my-feature-or-fix).
    • Coding Standards: Follow the project’s code style (often enforced by Linters like ESLint and formatters like Prettier – run npm run lint and npm run format).
    • Testing: Write tests for your changes if applicable. Ensure all tests pass (npm test).
    • Committing Changes: Write clear and concise Git commit messages.
    • Submitting a Pull Request (PR): Push your branch to your fork (git push origin my-feature-or-fix) and then open a Pull Request from your fork’s branch to the main project’s main or develop branch on GitHub. Describe your changes clearly in the PR description.

  3. Engage in Code Review: Project maintainers will review your PR. Be open to feedback and make requested changes. This is a key part of the collaborative learning process.

4.3 Joining the Community

Engage with other developers and players:

  • GitHub Issues: Participate in discussions on existing issues or report new ones.
  • GitHub Discussions: If the repository has Discussions enabled, use it for Q&A, ideas, and general chat.
  • Discord/Slack/Forum: Check the README.md for links to any official community chat platforms. This is often the best place for real-time interaction and help.
