Unity Web Game features analysis

The Unity Web game is run in the browser's Unitywebplayer plugin, the mode of operation is webplayer.unity3d+html

UnityObject2 's Initplugin function is called in a Web page that embeds Unitywebplayer, and Webplayer.unity3d is passed in as a parameter to initialize the running environment of the unity Web game.

Note: game DLLs and other managed DLLs will be written to the Webplayer.unity3d file when building the Web version

unityobject2.js ( other links 1 other Links 2)

A function that detects the unity Web player plug-in, initializes its installation, and embeds unity content. You can deploy the Unityobject2.js file to a network server with an HTML file.

However, it is best to load directly from the Unity server at the address: http://webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject2.js or https:// Ssl-webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/unityobject2.js (to get HTTPS support).

This way, you will always use the latest version of UnityObject2. and the Unityobject2.js file hosted on the Unity server is compressed, making it smaller and saving traffic.

Unityobject2.js source files can be found in the Data\resources folder in the Windows System Unity Editor and in the Contents/resources folder in Mac OS x.

Browser support Scenarios

As the major browser vendors began to gradually do not support browser plug-ins, Unity5.4 and later versions, Untiywebplayer was removed, only provide WEBGL export to support web games. unitywebplayer Road Map

Browsers that support Unitywebplayer are:

Windows platform Browser- IE Series (note: The latest is IE11. Win10 started using edge as the default browser, andedge does not support plugins. In addition, in order to access the Web site that needs plugins, WIN10 also provides IE browser)

Mac OS X Platform browser- Safari

Cross-platform browser-versions prior to Chrome 45, versions prior toFirefox 52.0, and versions prior toOpera 37

Domestic browser-such as: QQ browser, 360 browser, etc. generally have 2 modes: Compatibility Mode (IE) and fast mode (chrome core)

Although the integrated Chrome kernel version is more than 45, these homegrown browsers will typically modify the integrated chrome kernel to support the operation of the Npapi plugin.

Note 1: In addition to IE is the use of ActiveX plug-ins, other browsers are NPAPI plug-ins

NOTE 2: The Chrome 42 version starts by default to disable the NPAPI plugin, but allows the user to turn it on manually, and by the 45 version it is forced to disable

Note 3: Firefox version 52.0 forces all NPAPI plugins except flash to be banned

Development and debugging skills

Print the log in the script to the browser's console window:

"C Onsole.log " " My log message " );

To run the game using development mode :

1. Do not disable the right-click menu in the HTML page

2. Hold down the ALT key and right-click on the Unitywebplayer plugin to pop up the following shortcut menu (a menu item with a release channel will be displayed)

3.%homepath%\appdata\locallow\unity\webplayer\player\beta-4.63.x.x-development version of Unitywebplayer will be downloaded to run the game

The output log will contain stack information

Attach Debugging Games

1. Need to open the debug switch in the HTML page

2. Open the Game Project project, "Debug"--"Attach Unity Debugger"

Unitywebplayer Security Sandbox (safety sandbox)

By Unitywebplayer Sandbox restrictions, Untiywebplayer accesses the method in the native module and throws the following exception:

Methodaccessexception:attempt to access a private/protected method failed.

If you want to use the functions in the Natvie module in Untiywebplayer, you can do this by indirect circumvention:

(1) Write a browser plugin, call the native module in the plugin

(2) in Untiywebplayer, the JS function is called by Externalcall, and the corresponding function in the plugin is called in the JS function, and finally the call to the native module is realized.
