UnityObject is a JavaScript script that simplifies Unity content embedding into HTML. It has functions to detect the Unity Web Player plugin, initiate Web Player installation and embed Unity content. Although it's possible to deploy UnityObject.js file on the web server alongside the HTML file it's best to load it directly from the Unity server at http://webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject.js. That way you will always reference the most up to date version of UnityObject. Please note that the UnityObject.js file hosted on the Unity server is minified to make it smaller and save traffic. If you want to explore the source code you can find the original file in the Data\Resources folder on Windows and the Contents/Resources folder on Mac OS X. UnityObject by defaults sends anonymous data to GoogleAnalytics which is used to help us identify installation type and conversion rate.

UnityObject是JavaScript脚本，简化了Unity的内容嵌入到HTML中。它具有检测Unity网络播放器插件的功能，初始化网络播放器的安装和嵌入Unity的内容。尽管也可以部署UnityObject.js文件和HTML文件一起在web服务器，最好从Unity服务器http://webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject.js加载文件。这样总能引用UnityObject的最新版本。请注意在Unity服务器上托管的UnityObject.js文件是压缩版，使其很小，以节省流量。如果你想浏览源代码，在Windows可以在安装目录Data\Resources文件夹找到，在Mac OS X在安装目录Contents/Resources文件夹找到。默认UnityObject会发生匿名数据到GoogleAnalytics，这是用来帮助我们确定安装类型和转换率。

Functions 功能

embedUnity

Embeds Unity content into HTML.

嵌入Unity内容到HTML。

Parameters 参数：

id - HTML element (placeholder) to be replaced by Unity content.
HTML元素（占位符），用来替换Unity内容。
src - Path to the web player data file. Can be relative or absolute.
网络播放器数据文件的路径，可以用相对或绝对路径。
width - Width of Unity content. Can be specified in pixel values (i.e. 600, "450") or in percentage values (i.e. "50%", "100%").
Unity内容的宽度。可以指定像素值（如600,450）或百分比值（如，50%,100%）。
height - Height of Unity content. Can be specified in pixel values (i.e. 600, "450") or in percentage values (i.e. "50%", "100%").
Unity内容的高度。可以指定像素值（如600,450）或百分比值（如，50%,100%）。
params - Optional. Object containing list of parameters. See Customizing the Unity Web Player loading screen and Customizing the Unity Web Player's Behavior for possible values.
可选参数。包含参数列表的对象。参见自定义Unity网络播放器加载的屏幕和自定义Unity网络播放器的行为可能的值。
attributes - Optional. Object containing list of attributes. These will be added to underlying <object> or <embed> tag depending on the browser.
可选属性。包含属性列表的对象。这些将被添加到<object> or <embed>标签，取决于浏览器。
callback - Optional. Function that will be called once Web Player is loaded. Function must accept single argument that contains following properties:
回调，可选参数。网络播放器加载时，函数将被调用一次。函数必须接受单个参数包含以下属性：
- success - Boolean value indicating whether operation has succeeded.
  成功 - 布尔值，指示是否已成功运行。
- id - Identifier of the Web Player object that has been loaded (same as placeholder).
  标识 - 已经被加载的网络播放器对象的标识（与占位符相同）。
- ref - Web Player object that has been loaded.
  引用 - 已经被加载的网络播放器对象。

Notes 注意：

This function usually returns before the operation fully completes. Thus it is not safe to access the Web Player object immediately. A callback function can be provided to get notification on completion. Alternatively call getObjectById repeatedly until it doesn't return a null value.

这个功能通常在返回之前操作全部完成。因此它并不是安全地立即访问网络播放器对象。一个回调函数可提供在完成时获取通知，另外屡次调用getObjectById，直到它不返回一个空值。
