Unity打包WebGL: 导入Vue

Unity打包WebGL: 导入Vue

1. 介绍

1.1 任务

记录将Unity项目打包成WebGL，并集成到Vue项目中的过程。

1.2 环境

  • Unity:2021.3
  • Vue: 2

2. Unity项目

2.1 UI界面

Unity打包WebGL: 导入Vue

2.2 添加插件

构建WebGL项目需要添加一个.jslib文件，用于Unity脚本函数与JavaScript函数交互
详细内容参考：Unity（WebGL）与JS通讯2022最新姿势

web.jslib文件内容

mergeInto(LibraryManager.library, {SayHello: function () {window.alert("hello vue");},ReportReady: function() {window.ReportReady();}
})

2.3 添加脚本CBtn.cs

为按钮添加脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.Runtime.InteropServices;public class CBtn : MonoBehaviour
{[DllImport("__Internal")]private static extern void SayHello();[DllImport("__Internal")]private static extern string ReportReady();public Text text;// Start is called before the first frame updatevoid Start(){ReportReady();}// Update is called once per framevoid Update(){if (Input.GetKeyUp(KeyCode.H)) {SayHello();}}public void SetToken(string token) {this.text.text = token;}
}

2.4 打包WebGL

2.5 修改index.html

在html文件引入其他js文件的格式，
具体参考: webGl使用jsLib与Js交互

</html>

3. Vue项目

3.1 项目初始化

3.2 引入WebGL项目

3.3 监听WebGL事件

  1. 修改App.vue
<template><div id="app"><HelloWorld msg="Welcome to Your Vue.js App"/></div>
</template><script>
import HelloWorld from './components/HelloWorld.vue'export default {name: 'App',components: {HelloWorld}
}
</script><style>
#app {font-family: Avenir, Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;text-align: center;color: #2c3e50;margin-top: 60px;
}
</style>
  1. 修改HelloWorld.vue
<template><div><div @click="send">尝试发送数据</div><iframeref="iframe"width="1200"height="800"scrolling="no"src="/Unity/index.html"frameborder="0"></iframe></div>
</template><script>
export default {name: 'HelloWorld',props: {msg: String},data () {return {}},mounted () {window.addEventListener('fn', this.unityWatch)this.$once('hook:beforeDestroy', () => {window.removeEventListener('fn', this.unityWatch)})},methods: {send () {// 发送数据this.$refs.iframe.contentWindow.send({id: 12,value: 34})},unityWatch (e) {alert(e.detail)}}
}
</script><!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped></style>

X. 参考

  1. 与Vue结合
    【vue】vue与unity交互（不需要任何第三方插件）
    unity发布webgl平台结合vue,并实现事件交互
    vue项目接入unity3D模块并进行数据通信
    vue与unity进行交互，包括unity发收，unity自动获取数据等
    Unity3D（2021版）打包成webgl和前端vue交互

  2. JS创建和触发 events, window.top.dispatchEvent
    创建和触发 events
