javascript – 将Unity WebGL项目导入Angular2组件

我希望将Unity WebGL项目集成到Angular2应用程序中.将所有这些脚本移动到Angular2组件的正确方法是什么？

首先,Unity WebGL会像这样导出index.html：

<!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>

我开始拆分它,首先我将样式表移动到模板.css文件中：

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

然后我将javascript移动到组件.ts文件中：

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 });
  }

}

然后对于.html模板我留下了这个：

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

但是,无论我尝试什么方法(比如在JS文件上使用’require’),ngAfterViewInit中的行总是会出错：“引用错误：未定义UnityLoader”.

应如何正确完成这样才能起作用？

解决方法:

所以我一直在搞乱这个……

我使用angular / cli @ latest 1.6.5进行运行

这是我的app.component.ts

import { Component, ngzone, OnInit } from '@angular/core';
import * as $from 'jquery';
declare const UnityLoader;
@Component({
 selector: 'app-root',
 templateUrl: './app.component.html',
 styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit{
public gameObject: any;

constructor(private ngzone: ngzone) {
  window.unity = window.unity || {};
  window.unity.GetUnityNumber = this.randomNumberFromunity.bind(this);
}

public ngOnInit(): void {
 this.init();
}
public helloUnity() {
 console.log(this.gameObject); // <-- always undefined ?
 this.gameObject.SendMessage('SetText', 'HELLO?');
 }

private init() {
 $.getScript('assets/UnityLoader.js').done(function ( bla , text) {
   this.gameObject = 
   UnityLoader.instantiate('gameContainer','assets/test.json');
   //gameObject not undefined at this stage..
  });
}
private randomNumberFromunity(input: string) {
  this.ngzone.run(() => {
      console.log('call from unity', input);
 });
}

}

在typings.d.ts中,我扩展了窗口元素.

interface Window {
  unity: any;
}

所以,当我从团结中打电话时,我称之为

Application.ExternalCall("unity.GetUnityNumber", rnd);

我现在所缺少的就是团结一致…也许你对这个有一个想法？

我将unity-build作为私有的npm包.构建时将所有内容复制到assets文件夹中.
