So, let's embark on this journey to unlock the power of Immutable Passport, enhancing your gaming application and expanding the horizons of blockchain technology in the world of gaming. Let's get started! 🎮🚀

Prerequisites:

1. A code editor for making changes to your application.
2. Node.js and npm installed on your development machine.
3. An account on the Immutable Developer Hub.

Step 1: Set Up Your Project

Start by creating a new directory for your project. You can choose any name you like. In this example, I'll name it immuatble-spaceinvaders. If you already have an existing game application, you can skip this step. However, make sure to navigate to your project's root directory.

mkdir immuatble-spaceinvaders
cd immuatble-spaceinvaders

If you prefer to start with a pre-existing game application, you can clone a basic game application repository from a version control system like GitHub. In this guide, I have cloned a basic Space Invaders game application repository and are now adding Passport integration and other functionalities to it.

git clone <repository-url>
cd <repository-directory>

Initialize a new Node.js project inside the cloned repository:

npm init -y

Step 2: Register Your Application on Immutable Developer Hub

To integrate Immutable Passport into your application, you need to register your application on the Immutable Developer Hub. Follow these steps:

1. Sign In to Immutable Developer Hub:

   If you don't already have an Immutable Developer Hub account, you'll need to create one. Follow these steps:

   • Visit the Immutable Developer Hub website.
   • Click on the "Sign In" option. If you don't have an account, select "Create Account" or "Sign Up" to create one.
   • Follow the on-screen instructions to complete the registration process.

   Once you have successfully created your account, return to the Immutable Developer Hub homepage and sign in with your newly created credentials.

2. Register a New Application:

   To register your application successfully, pay attention to the following details:

   • Click on the "My Applications" or "Create New Application" option, depending on the interface of the Immutable Developer Hub.
   • Select "Web Application" as the application type. As of the time of writing, this is the only available option.
   • Provide a unique name for your application in the "Client Name" field. Make sure it's easily identifiable.
   • In the "Logout URLs" section, enter valid URLs where users can securely log out. These URLs should point to the logout functionality of your application.
   • In the "Callback URLs" section, ensure that your application's callback URL matches what you provided during the Passport client initialization. This is crucial for proper integration.
   • Follow the on-screen instructions to complete the registration process. This may include agreeing to terms and conditions or specifying additional settings based on your application's requirements.

3. Obtain Client Credentials:

   After successfully registering your application, you will receive the client credentials required for integrating Immutable Passport. These credentials are essential for authentication and authorization.

   Once your application is registered, you will receive a "Client ID." Save this Client ID as you will need it for the next steps.

4. Add the Client ID to Your Application's Environment Variables:

   To securely store and use the Client ID in your application, it's recommended to add it to your environment variables. Here's how you can do it:

   • Create a .env file in your project directory if you don't have one already.

   • Inside the .env file, add the following line, replacing "Your_Client_ID" with the actual Client ID you received:

     IMMUTABLE_CLIENT_ID="Your_Client_ID"
     

   • Save the .env file.

   Ensure that your application is set up to read environment variables. Depending on your programming language and framework, you may need to configure this specifically. Consult the documentation for your technology stack if you are unsure.

Step 3: Install Dependencies

Install the required Node.js packages:

npm install -D @imtbl/sdk

Step 4: Set Up Your Game Application

1. Create your project structure with the necessary files, including index.html, passport.js, login.js, and game-related files.

2. Add your game code to the relevant game files (e.g., sketch.js).

Step 5: Configure Passport

In the passport.js file, configure Immutable Passport using the obtained client_id. Replace 'YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET', and 'YOUR_REDIRECT_URI' with the credentials you obtained during registration.

// passport.js
window.passport = new window.immutable.passport.Passport({
  baseConfig: new window.immutable.config.ImmutableConfiguration({
    environment: window.immutable.config.Environment.SANDBOX, // Use PRODUCTION for a live environment.
  }),
  clientId: "your-client-id", // Replace

 with your actual client ID
  redirectUri: "your-redirect-uri",
  logoutRedirectUri: "your-logout-redirect-uri",
  audience: "platform_api",
  scope: "openid offline_access email transact",
});

()

Step 6: Implement User Authentication

In the login.js file, implement the login logic. This code allows users to connect to Passport and authenticate.

// login.js
window.provider = window.passport.connectEvm();

const connectPassport = async function () {
  const passportBtn = document.getElementById("btn-passport");
  passportBtn.innerHTML = "Loading...";
  passportBtn.disabled = true;

  try {
    window.accounts = await window.provider.request({
      method: "eth_requestAccounts",
    });
    if (window.accounts) {
      await getUserInfo();
    }
  } catch (error) {
    console.error("Error connecting to Passport:", error);
    passportBtn.innerHTML = "Connect Passport";
    passportBtn disabled = false;
  }
};

()

Step 7: Display User Information in Your Game

Modify your game logic (e.g., sketch.js) to personalize the game for authenticated users. This code checks if user information is available and customizes the game accordingly.

// sketch.js
function draw() {
  if (window?.userProfile?.email) {
    // Game is in progress, authenticated user.
    // Modify the game based on user information.
    // ...
  } else {
    // Show a start screen for non-authenticated users.
    // ...
  }
}

Step 8: Implement User Logout

In your login.js file, implement the logout function. This code allows users to log out of their Passport session.

// login.js
const passportLogout = async function() {
    try {
        await window.passport.logout();
        window.userProfile is set to an empty object;
    } catch (error) {
        console.error("Error logging out:", error);
    }
};

Step 9: Initiate a Transaction

You can initiate a transaction from Passport by using the Passport JavaScript SDK. Implement a function to initiate a transaction. This code initiates a transaction with a placeholder string.

// Implement a function to initiate a transaction
const initiateTransaction = async () => {
  try {
    const transactionHash = await window.passport.createTransaction(
      "your-placeholder-string"
    );
    // Handle the transaction result
  } catch (error) {
    console.error("Error initiating transaction:", error);
  }
};

You can call this function from your game logic when the user performs a specific action.

With these steps, you'll have a simple game application integrated with Immutable Passport authentication, and you'll be able to register the application, authenticate users, display tokens and user info, log users out, and initiate transactions with Passport.

Conclusion
