![]() The native Web support converts that C# to C++ code and then produces asm.js using the Emscripten compiler. Unity's long-term goal is to enable portable, safe code that will run on any of its supported platforms, using Unity's C# scripting. Unity has seen considerable developer interest in a WebGL version of its engine, so the two companies worked together to make it happen. Mozilla first approached Unity to investigate the possibility of porting its engine to Web technologies two years ago. The generated code takes advantage of some of the new browser APIs that Mozilla is pushing, such as support for gamepads. Unity is looking for feedback from developers during this early access preview to refine and improve the engine prior to producing a final version. While the WebGL/asm.js version of the Unity engine is not as fast as the plug-in version, the companies say that it's still good enough to hit 60 frames per second in a range of games. Initially, it will only support desktop Firefox and desktop Chrome, due to their performance and (in Firefox's case) explicit support for the high performance asm.js subset.Ī bunch of Unity games running in the browser with WebGL. The early access will remove the need for the plug-in. Unity games can also be deployed on the Web, but this function currently uses a browser plug-in, the Unity Web Player. The Unity game engine has found huge success among game developers as it can target Windows, iOS, Android, OS X, Linux, PlayStation 3, Xbox 360, and more. Mozilla and Unity today announced that Unity 5, to be released later this year, will include an early access preview of a version of the 3D engine that supports WebGL and asm.js, enabling plug-in-free access to the Web.

It is only listed in this compatibility table for completeness. For this reason, we will show a warning about using an unsupported browser when opening content in Internet Explorer. Internet Explorer does not support audio and is too slow to support most Unity WebGL content with decent results.See Memory Considerations for more information on memory usage. Chrome may need a large amount of memory to parse the generated JavaScript code, which can cause out-of-memory errors or crashes when loading content on 32-bit browsers.Browsers which implement asm.js support may be able to run Unity WebGL content faster, because Unity uses asm.js. Firefox 43 and higher will fix this.įirefox supports WebGL 2.0, but it is disabled by default and needs to be enabled in about:config.Ĭhrome supports WebGL 2.0, but it is disabled by default and needs to be enabled in chrome://flags.Īsm.js is a susbset of JavaScript for which a browser can specifically optimize. ![]() Required for local storage as used by the Data Caching feature, the PlayerPrefs class, and Yesįirefox up to version 42 and Safari will not support IndexedDB for content running in an iFrame. Safari supports the HTML5 full-screen API, but no keyboard input when in full-screen mode, so Unity will disable full-screen functionality when running in Safari. The Web Audio API is required to play sound in Unity WebGL content. Details available on the Mozilla wiki page on Blocklisting/Blocked Graphics Drivers and the Khronos wiki page on Blacklists and Whitelists. WebGL may be unsupported for specific older graphics cards. Support should continue for future versions, but may not be stable in previous versions. Following the discovery of a security issue in the Unity Web Player plugin that can allow an attacker to use a victim’s credentials to read messages or otherwise. Note that this compatibility table is valid for the specific versions of the browsers as stated. Microsoft has since released Windows 10 with their new Edge browser (which supports asm.js and is now enabling it by default) - so we were interested to see how that competes. For this reason, Unity WebGL shows a warning message when trying to load content on mobile browsers (which can be disabled if needed). It may still work, especially on high-end devices, but many current devices are not powerful enough and don’t have enough memory to support Unity WebGL content well. Note that Unity WebGL content is not currently supported on mobile devices. See the table below for an overview of browser features of interest to Unity WebGL content, and which browsers support them. However, the level of support and the expected performance varies between different browsers. Unity WebGL supports all major desktop browsers to some degree.
