Tweed SDK Unity Example

The files for the bridge can be found under the tweed_assets folder. the deploy.sh script will put them in the right places, all you need to do is to compile the WebGL example using Unity.

Using the Tweed-Unity SDK connector

npm install

npm run deploy

Open the unity example from: ./unity/example Compile to WebGL (file --> Build Settings... --> WebGL --> Build) to ./unity/deploy/tweed

run the BE:

npm run backend

Run the FE:

npm run frontend

Open the browser and hit http://localhost:5173/ to see the example running

The Backend

The backend has two roles:

1. To integrate the Tweed Backend SDK
2. To serve the Unity files

There are 4 files that needs to be pulled by the frontend: loader - the code that pulls the other packages framework - the unity wrapper wasm - the actual app data - misc data that the app needs

The frontend

The frontend is a vite project that imports two js files:

1. unityPreloader.js - The file that fetches the unity files from the backend
2. TweedSDK.js - The file that setup the Tweed SDK and routes the calls from the unity to the SDK

The Unity connector

The unity connector is build from two files:

1. TweedSDK.jslib - The module that is forming the channel Unity -> Browser
2. TweedSDK.cs - The file that gives the Unity the Tweed functionality and gets the data from the browser (Browswer -> Unity)

The deploy.sh script will put the files in the right paths of the example.

Architecture

[TweedSDK.cs] -> [TweedSDK.jslib] -> [TweedSDK.js]
[Unity] [Unity-Browser] [Browser]
