Unity 中WebGL的设置

1. 使用压缩格式：Project Settings->Player->Publishing Settings，将Compression Format设置为Gzip，Decompression Fallback设置为true
2. 发布：Build Settings->Build，我是发布到新建的html文件夹

Ubuntu Apache web服务器搭建

1. 安装 apache(Ubuntu20.04)

sudo apt-get install apache2

2. 设置web资源，将之前发布的html文件夹拷贝到/var/www/html

3. 添加配置文件，html/Build新建以下.htaccess文件【Unity文档】

# This configuration file should be uploaded to the server as "<Application Folder>/Build/.htaccess"
# NOTE: "mod_mime" Apache module must be enabled for this configuration to work.
<IfModule mod_mime.c>

# The following lines are required for builds without decompression fallback, compressed with gzip
RemoveType .gz
AddEncoding gzip .gz
AddType application/octet-stream .data.gz
AddType application/wasm .wasm.gz
AddType application/javascript .js.gz
AddType application/octet-stream .symbols.json.gz

# The following lines are required for builds without decompression fallback, compressed with Brotli
RemoveType .br
RemoveLanguage .br
AddEncoding br .br
AddType application/octet-stream .data.br
AddType application/wasm .wasm.br
AddType application/javascript .js.br
AddType application/octet-stream .symbols.json.br

# The following line improves loading performance for uncompressed builds
AddType application/wasm .wasm

# Uncomment the following line to improve loading performance for gzip-compressed builds with decompression fallback
# AddEncoding gzip .unityweb

# Uncomment the following line to improve loading performance for brotli-compressed builds with decompression fallback
# AddEncoding br .unityweb

</IfModule>

4. 重启服务器

/etc/init.d/apache2 restart

5. 查看网页
   输入以下命令查看服务器IP(需要先安装net-tools)

ifconfig

在其他同一局域网的电脑上打开一个支持webGL的浏览器，输入之前查到的IP地址即可查看发布的网页界面

网页修改

打开html/index.html文件进行接下来的修改

1. 添加按钮(主要是为了调试html与unity交互正常与否)
   在body中加入以下代码

<button style="margin: 20px; padding: 15px" onclick="回调函数名(形参)">按钮显示的文本</button>

下图是我放置的位置

2. 声明和赋值实例【十分重要，js调用的关键】
   在script中添加以下代码

var myGameInstance=null;
//其他。。。。。。。。
      script.onload = () => { 
   
        createUnityInstance(canvas, config, (progress) => { 
   
          progressBarFull.style.width = 100 * progress + "%";
        }).then((unityInstance) => { 
   
          myGameInstance=unityInstance;//注意加入这一句
          loadingBar.style.display = "none";
          fullscreenButton.onclick = () => { 
   
            unityInstance.SetFullscreen(1);
          };
        }).catch((message) => { 
   
          alert(message);
        });
      };

3. js调用Unity函数
   在script中自定义函数

function update(jointIndex,qx,qy,qz,qw)
{ 
   
	//最近发现只允许调用至多一个形参的函数
	myGameInstance.SendMessage('GameObject名称','公共函数名',形参)
}

附一：Ubuntu 文件操作常用命令

1. 复制文件夹

cp A B -r

2. 删除文件

rm -rf A

3. 重命名文件

mv A B

附二：Apache 服务器常用操作命令

1. 查看服务器状态

systemctl status apache2

2. 开关重启服务器

/etc/init.d apache2 start
/etc/init.d apache2 stop
/etc/init.d apache2 restart
