Features

The B3 Unity SDK provides comprehensive integration capabilities for Unity developers:

Session Management

The SDK automatically and seamlessly handles user authentication.

APIs as Functions

Use all of the launcher APIs easily with support for both callback based AND async/await based calls.

Webhooks for WebGL

Handles launcher client webhooks, and parses and propagates them to your own C# Code.

​
Installation and Usage

1

Download the SDK

Head over to the GitHub repository and download the latest release.

Code Examples

​
Trigger Rules Engine

Here’s an example of how to trigger the rules engine from within your Unity game:
Unity C# Example
B3LauncherClient.TriggerRulesEngine(new B3LauncherClient.TriggerRulesEngineBody
{
    launcherJwt = B3Instance.Instance.SessionJWT ?? jwtInput.text,
    trigger = "open-tip-modal",
    otherWallet = otherWalletInput.text,
}, null);

​
Session Management

The SDK automatically handles user sessions:
Session Example
// Access the current session JWT
string sessionToken = B3Instance.Instance.SessionJWT;

// Check if user is authenticated
if (B3Instance.Instance.IsAuthenticated)
{
    // User is logged in and ready to interact with B3 services
    Debug.Log("User authenticated successfully");
}

​
API Integration

The Unity SDK provides seamless access to all B3 launcher APIs:
Traditional callback pattern for handling API responses:
B3LauncherClient.SomeAPICall(requestData, (response) => {
    // Handle response
    Debug.Log("API call completed");
});
Modern async/await pattern for cleaner code:
public async void CallAPI()
{
    var response = await B3LauncherClient.SomeAPICallAsync(requestData);
    // Handle response
    Debug.Log("API call completed");
}
Handle launcher events in WebGL builds:
// Register webhook handlers
B3Instance.Instance.OnWebhookReceived += HandleWebhook;

private void HandleWebhook(WebhookData data)
{
    // Process incoming webhook data
    Debug.Log($"Received webhook: {data.type}");
}
