Unity Bridge for Gaming

Utilize Tweed's SDK in a WebGL compiled Unity game

With the Unity bridge, developers can embed all of the blockchain and web3 functionalities found in Tweed's SDK into a WebGL-compiled Unity game. With a simple integration process, players can:

  • Own an in-game crypto wallet

  • Send and receive tokens and NFTs

  • Buy NFTs using their payment card

  • View their transactions

  • Play in a multi-chain environment (EVM and non-EVM)

  • Interact with smart contracts

  • And much more...

This is how it works:

The integration with the SDK doesn't change: a JS backend SDK and a frontend SDK will still need to be integrated into the platform, in addition to the following 3 files for the Unity bridge:

  1. TweedSDK.cs - Handles the calls to the SDK functions from the Unity MonoBehaviour object

  2. TweedSDK.jslib - Handles the communication from the Unity app to Tweed's frontend SDK

  3. TweedSDK.js - Handles the communication from Tweed's frontend SDK to the Unity app

The Unity-JS bridge can be downloaded from our Unity bridge GitHub repo.

Unity Bridge Installation and Setup


The bridge should be incorporated into the Unity app to allow in-game blockchain functionality.

  • TweedSDK.cs --> <UnityProjectPath>/Assets/

  • TweedSDK.jslib --> <UnityProjectPath>/Assets/plugins

  • TweedSDK.js --> <FrontendProjectPath>

The first two files will get baked into the WebGL-compiled app using the Unity compiler. Compiling the Unity app will be done using: File --> Build Settings... --> WebGL --> Build The third file will get loaded into the frontend that hosts the Unity WebGL app using something like:

<script type='module' type='text/javascript' src='/src/TweedSDK.js'></script>

Usage Example

Use our JS documentation to learn about the SDK functionality. Every function is divided to two parts:

  • function_name - calling the SDK function

  • function_name_cb - a callback function that will have the returned data

Calling the following function:


Will return the wallet address in GetOrCreateWallet_cb
