What happened?

I am using react-unity-webgl for loading unity game. Its working fine when i am in App.js file. But when i use routing its crash and didn't show anything. If i dont use react-unity-webgl then other things are working fine. I searched alot but didn't find any solution

Reproducible test case

import {Box, Card, Container, Grid, Input, InputAdornment, Stack, Typography,} from '@mui/material';
import { Unity, useUnityContext, } from "react-unity-webgl";
import {styled} from "@mui/material/styles";
import useSettings from "../../hooks/useSettings";
import Page from "../../components/Page";
import cssStyles from "../../utils/cssStyles";

const APPBAR_MOBILE = 50;
const APPBAR_DESKTOP = 64;
const SearchbarStyle = styled('div')(({theme}) => ({
    ...cssStyles(theme).bgBlur(),
    // top: 0,
    // left: 0,
    zIndex: 99,
    width: '90%',
    display: 'flex',
    // position: 'absolute',
    alignItems: 'center',
    borderRadius: 8,
    height: APPBAR_MOBILE,
    padding: theme.spacing(0, 1),
    boxShadow: theme.customShadows.z8,
    [theme.breakpoints.up('md')]: {
        height: APPBAR_DESKTOP,
    },
    [theme.breakpoints.down('md')]: {
        height: APPBAR_MOBILE,
        padding: theme.spacing(0, 1),
        width: '96%',
    },
}));

export default function UnityGame() {

    const { unityProvider,unload } = useUnityContext({

        loaderUrl: 'Build/Build.loader.js',
   dataUrl: 'Build/Build.data',
   frameworkUrl: 'Build/Build.framework.js',
   codeUrl: 'Build/Build.wasm',

   });

    const {themeStretch} = useSettings();
    return (
        <Page title="Ecommerce: Product List">
            <Container maxWidth={'xl'}>
            <Unity unityProvider={unityProvider}  />

            </Container>
        </Page>
    );
}

Switching from BrowserRouter to HashRouter solved the issue for me.

I have the same issue, where UnityWebGL is stuck on the loading scene. I used Unity 2022.3.45f1, then loaded using HashRouting pages in React with Vite (jsx files), anddespite having hashrouting the problem persist.

Here is the code:

import '../App.css'; import React from "react"; import Header from '../components/Header'; import Footer from '../components/footer'; import { Unity, useUnityContext } from "react-unity-webgl";

function Game() { const { unityProvider, loadingProgression, isLoaded } = useUnityContext({ loaderUrl: "../../public/buildUnity/Builds WorldeCrackdown.loader.js", dataUrl: "../../public/buildUnity/Builds WorldeCrackdown.data", frameworkUrl: "../../public/buildUnity/Builds WorldeCrackdown.framework.js", codeUrl: "../../public/buildUnity/Builds WorldeCrackdown.wasm", });

return (

    <div>
        <Header />
        <div id="GameSection">

            {!isLoaded && (
                <p>Loading Application... {Math.round(loadingProgression * 100)}%</p>
            )}
            <Unity

                unityProvider={unityProvider}
                style={{
                    visibility: isLoaded ? "visible" : "hidden",
                    width: "75%",
                    height: "84vh",
                    justifySelf: "center",
                    alignSelf: "center"
                }}
            />
        </div>
        <Footer />
    </div>

);

}

export default Game

I also want to add that the component runs in npm run dev, but not after the web is built, npm run build.
