Peacemaker Unity React SEI SDK

Peacemaker SDK integrates Unity WebGL with Sei blockchain. Enables initiating transactions from within Unity and receiving responses as callbacks.

Installation

Install the package using npm:

npm install peacemaker-unity-react-sei-sdk

Also make sure you have all the required peer dependencies installed:

npm install @sei-js/core @sei-js/react react react-dom react-unity-webgl

To effectively use the integration you also have to have a crypto wallet such as Compass installed as an extension in your browser.

Usage

React bindings

Import the Peacemaker component from the package and wrap your Unity scene in it. Pass paths to the Unity WebGL files as props (loaderUrl, frameworkUrl, codeUrl, dataUrl).

import { Peacemaker } from 'peacemaker-unity-react-sei-sdk';

export default function App() {
    return (
        <Peacemaker
            loaderUrl="unity/Build/Build.loader.js"
            dataUrl="unity/Build/Build.data"
            frameworkUrl="unity/Build/Build.framework.js"
            codeUrl="unity/Build/Build.wasm"
            timeoutMs={30_000}
            width="100%"
            height="100%"
        />
    );
}

Optionally, you can pass a timeoutMs prop to set the maximum time in milliseconds to wait for user's response to authentication request. Default is 30 seconds.

You can also set a custom size of your Unity scene by passing width and height string props as in the example above (either as percentages or pixels, e.g. "100%" or "600px").

Unity C# bindings

The instructions for configuring your Unity project and using C# API can be found in the following repository.

React Project Example

Example of creating a React project with Vite and using the Peacemaker component:

1. Create Vite project

npm create vite@latest my-unity-react-app

Then chose React and then Typescipt in the CLI prompt.

2. Install dependencies

cd my-unity-react-app
npm install

3. Install Peacemaker

npm install peacemaker-unity-react-sei-sdk
npm install @sei-js/core @sei-js/react react react-dom react-unity-webgl

4. Move your Unity WebGL files into the Vite project

Create a unity folder in the src/public directory of your project and move your Unity WebGL files (Build.loader.js, Build.data, Build.framework.js, Build.wasm) into it.

5. Add Peacemaker component to your app

Open src/App.tsx file, remove all the content and add the following code instead:

import './App.css';
import { Peacemaker } from 'peacemaker-unity-react-sei-sdk';

function App() {
    return (
        <Peacemaker
            loaderUrl="unity/Build/Build.loader.js"
            dataUrl="unity/Build/Build.data"
            frameworkUrl="unity/Build/Build.framework.js"
            codeUrl="unity/Build/Build.wasm"
            timeoutMs={30_000}
            width="800px"
            height="600px"
        />
    );
}

export default App;

Ensure that paths and casing are correct and match Unity WebGL files mentioned in the previous step.

6. Run the app

Start Vite in development mode:

npm run dev

then go to http://localhost:5173 in your browser.

If you are using an example Unity project found in the C# SDK repository, you will see an example Unity scene with a Login button in it. Once you click it, you will be redirected to the Compass Sei Wallet to authenticate your account. After you login, you will see a message in Unity console with your account address.

Demo

Limitations

Note that this package is still in development, there is still a lot to do to fully support an effective integration. Reach out on github in case of any issues.
