1.发布部署出来的链接放到手机上测试。
ios：20秒读条然后闪退；vivo:9秒读条闪退；小米：15秒进入
然鹅，资料只有130kb的图片。
2.报这个警告，修改Build文件夹里的UnityLoader.js取消
移动端展示弹出提示框，点击OK后继续打开webgl
please note the unity webgl is not currently supported on mobiles.press ok if you wish to continue anyway.
请注意，手机目前不支持unity webgl。如果仍要继续，请按ok。
修改UnityLoader.js：
compatibilityCheck:function(e,t,r)
UnityLoader.SystemInfo.hasWebGL?
UnityLoader.SystemInfo.mobile?
t()
:["Firefox","Chrome","Safari"].indexOf(UnityLoader.SystemInfo.browser)==-1?
t()
:t()
:e.popup("Your browser does not support WebGL",[text:"OK",callback:r])
,
Blobs:,loa...(省略)
3.自适应屏幕修改和手机端强制横屏index.html
因为浏览器的分辨率不一样，所以我上面的button都不在原位置，而且分辨率小的浏览器显示的画布都不全，就得做自适应。
还有PC端是横版的，要是手机端是竖版的就得做两套UI，判断webgl是运行在PC端还是手机端，然后jslib本地插件从浏览器获取屏幕分辨率数据再把数据传回unity再通过screen.Resolution()函数设置画布的大小有点麻烦，我们直接就手机端强制横屏了。（测试最新判断unitywebgl运行在PC还是手机端的方法报了五个错打出来的空包，老办法PC是cube 手机端是sphere还是可以的）

var gameInstance = UnityLoader.instantiate("gameContainer", "Build/num3.json", onProgress: UnityProgress);
function ChangeCanvas()
document.getElementById("gameContainer").style.width = window.innerWidth + "px";
document.getElementById("gameContainer").style.height = window.innerHeight + "px";

.webgl-content
width : 100vw;
height : 100vh;
</style>

</html>
.webgl-content * border: 0; margin: 0; padding: 0
/*添加 width: 100%; height: 100%;*/
.webgl-content position: absolute; top: 50%; left: 50%; width: 100%; height: 100%; -webkit-transform: translate(-50%, -50%); transform: translate(-50%, -50%);

/*如果你要保存 footer模块, 然后又要让footer显示在最顶部,这样处理*/

.webgl-content .footer .title margin-right: 10px; float: right;
.webgl-content .footer .fullscreen background-image: url('fullscreen.png'); width: 38px; float: right;
4.logo替换成gif进度加载的样式、背景图替换
.webgl-content * border: 0; margin: 0; padding: 0
.webgl-content position: absolute; top: 50%; left: 50%; -webkit-transform: translate(-50%, -50%); transform: translate(-50%, -50%);
.webgl-content .logo, .progress position: absolute; left: 50%; top: 50%; -webkit-transform: translate(-50%, -50%); transform: translate(-50%, -50%);
.webgl-content .logo background: url('person.gif') no-repeat center / contain; width: 154px; height: 130px;
.webgl-content .progress height: 18px; width: 141px; margin-top: 90px;
.webgl-content .progress .empty background: url('progressEmpty.Light.png') no-repeat right / cover; float: right; width: 100%; height: 100%; display: inline-block;
.webgl-content .progress .full background: url('progressFull.Light.png') no-repeat left / cover; float: left; width: 0%; height: 100%; display: inline-block;
.webgl-content .logo.Dark background-image: url('person.gif');
.webgl-content .progress.Dark .empty background-image: url('progressEmpty.Dark.png');
.webgl-content .progress.Dark .full background-image: url('progressFull.Dark.png');
.webgl-content .footer margin-top: 5px; height: 38px; line-height: 38px; font-family: Helvetica, Verdana, Arial, sans-serif; font-size: 18px;
.webgl-content .footer .webgl-logo, .title, .fullscreen height: 100%; display: inline-block; background: transparent center no-repeat;
.webgl-content .footer .webgl-logo background-image: url('webgl-logo.png'); width: 204px; float: left;
.webgl-content .footer .title margin-right: 10px; float: right;
.webgl-content .footer .fullscreen background-image: url('fullscreen.png'); width: 38px; float: right;
背景图在webgl.json里改，再替换unityloader.js
