Is there any convinent way to sync data between unity and react?

[imwangji]

i'm new to unity and this library,please don't mind my stupid questions : I have 2 questions, please help me if you can:

1. I found I have to sync data between unity and react in this way below:
   unity: add DataClass to Global Entries;
   react: read Global Entrie, set data like this globals.DemoManager.GetComponent("DemoManagerScript").username
   anyway, this sentense is a little bit verbose, is there any convinent way to do that?

2. I change data in Unity,but react does'nt change UI. what should I do?

thanks for your help.

Hey. Do not worry, your question is very valid and was asked many times. It is a topic that should be in the documentation but I didn't have time to do it yet.

1. Currently, this is the way to do it. If you want to make it shorter, you can assign it to a variable, or add DemoManagerScript directly to the globals, like this:

2. If you want your changes to Globals to cause a rerender, you need to use useGlobals.

However, this will only rerender on changes to the Globals itself, not its nested properties. For example, if you change username of DemoManagerScript, it won't cause a rerender. To do that, you can set it in Globals manually like Globals["username"] = username.

But there is also a mechanism to handle that. It is called watchables and it is similar to Globals. You can use it like:

C# side:

public class DemoManagerScript : MonoBehavior {
  public ReactUnity.Helpers.Watchable<string> username = "hello world";
  // .....
}

React side:

import { useGlobals, useWatchable } from '@reactunity/renderer';

function App() {
  var globals = useGlobals();
  var demoManager = globals.DemoManager.GetComponent("DemoManagerScript");
  var username = useWatchable(demoManager.username);

  // ....
}
