This 2D top-down shooter is headed to the Playstation 4, but that didn’t stop it from appearing on the Xbox 360 and even in the browser through Turbulenz‘s WebGL framework first. I have an in-depth tutorial on how to use emscripten, as well as a clear explanation of what asm.js is. Even better, emscripten converts OpenGL, a desktop graphics API, into WebGL, which is the web variant of that API. In short: near native speeds, using C and C++, inside of the browser. This is made possible by a technology known as emscripten.Įmscripten is an LLVM based project that compiles C and C++ into highly performant JavaScript in the asm.js format. Although only JavaScript will run in the browser, you can still write in other languages and still compile to JavaScript, thereby allowing it to also run in the browser. JavaScript is the only language which works in all web browsers. With the advent of WebGL and now asm.js, developers can now harness much of the power of their computing device from within the browser and access markets previously unavailable. The need for ActiveX controls has been significantly reduced by HTML5-era capabilities, which also produces interoperable code across browsers. Microsoft is following suit and deprecating ActiveX, VBScript, attachEvent, and other legacy technologies in favor of web standards. There are a number of reasons as to why, but most notably they stated “hangs, crashes, security incidents, and code complexity.” Google suggests using web standards instead, such as WebGL, which I will explain below. In April, with the release of Chrome 42 stable, they finally put the axe to it. Chrome killed support for NPAP (Netscape Plugin API), but announced it over one year ago. Unity previously had a web player, which was a downloadable plugin that used ActiveX. Unity, and Epic’s Unreal Engine, the popular middleware tools frequently used by game developers are not limited to creating compiled applications that run as an executable.
