Import a Unity WebGL project into an Angular2 component

I want to integrate a Unity WebGL project into an Angular2 application. What is the correct way to move all of this script into an Angular2 component?

First, Unity WebGL exports index.html as follows:

<!DOCTYPE html>
<html lang="en-us">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Unity WebGL Player | Espoo web manager (Prefab preview)</title>
    <link rel="shortcut icon" href="TemplateData/favicon.ico">
    <link rel="stylesheet" href="TemplateData/style.css">
    <script src="TemplateData/UnityProgress.js"></script>  
    <script src="Build/UnityLoader.js"></script>
    <script>
      var gameInstance = UnityLoader.instantiate("gameContainer", "Build/builds.json", {onProgress: UnityProgress});
    </script>
  </head>
  <body>
    <div class="webgl-content">
      <div id="gameContainer" style="width: 960px; height: 600px"></div>
      <div class="footer">
        <div class="webgl-logo"></div>
        <div class="fullscreen" onclick="gameInstance.SetFullscreen(1)"></div>
        <div class="title">Espoo web manager (Prefab preview)</div>
      </div>
    </div>
  </body>
</html>

I started sharing this, and first I moved the stylesheet to the template .css file:

@import './webgl-app/TemplateData/style.css';

Then I moved javascript to the .ts-file component:

import { Component, AfterViewInit } from '@angular/core';
import './webgl-app/TemplateData/UnityProgress.js';
import './webgl-app/Build/UnityLoader.js';

declare var UnityLoader: any;
declare var UnityProgress: any;

@Component({
  selector: 'app-unity-prefab-preview',
  templateUrl: './unity-prefab-preview.component.html',
  styleUrls: ['./unity-prefab-preview.component.css']
})
export class UnityPrefabPreviewComponent implements AfterViewInit {
  constructor() {}

  gameInstance: any;

  ngAfterViewInit() {
    this.gameInstance = UnityLoader.instantiate("gameContainer", "./webgl-app/Build/builds.json", { onProgress: UnityProgress });
  }

}

And then for the .html template I left this:

<div class="webgl-content">
  <div id="gameContainer" style="width: 960px; height: 600px"></div>
</div>

However, no matter what approach I try to use (for example, instead of “require” in JS files), a line in ngAfterViewInit always throws an error: “Link error: UnityLoader not defined”.

How should this be done correctly for it to work?

Unity WebGL :

1) WebGL /unity Angular ( , src). Build /src/assets/unity:

  • unity.json
  • unity.data.unityweb
  • unity.wasm.code.unityweb
  • unity.wasm.framework.unityweb

unity build files

2) UnityProgress.js UnityLoader.js angular.json :

"scripts": [
  "unity/TemplateData/UnityProgress.js",
  "unity/Build/UnityLoader.js"
],

3) (optional) Add style.css to your angular.json styles

"styles": [
  "node_modules/font-awesome/css/font-awesome.css",
  "src/assets/theme.scss",
  "src/styles.scss",
  "unity/TemplateData/style.css"
],

4) Add the basic Unity HTML code to your component.html :

<div class="webgl-content">
  <div id="unityContainer" style="width: 960px; height: 600px"></div>
  <div class="footer">
    <div class="webgl-logo"></div>
    <div class="fullscreen" (click)="unityInstance.SetFullscreen(1)"></div>
    <div class="title">UnityProject</div>
  </div>
</div>

5) Finally, create an instance of yours unityContainerin your component.ts :

import { Component, OnInit, AfterViewInit } from '@angular/core';
declare var UnityLoader: any;

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent implements OnInit, AfterViewInit {
  unityInstance: any;

  constructor() { }

  ngOnInit() { }

  ngAfterViewInit() {
    this.unityInstance = UnityLoader.instantiate("unityContainer", "assets/unity/unity.json");
  }

}
