How To Design A Mobile Game With HTML5

Advertisement Care to make a cross-platform mobile game with HTML5? No need to dabble in Java or Objective-C? A handful of game developers are pushing the envelope of mobile HTML5 games at the moment. Getting Started Before you start sketching the next Temple Run or Angry Birds, you should be aware of a few things that could dampen your excitement: Performance Mobile browsers are not traditionally known for their blazing JavaScript engines. Now, as a Web developer you’re used to dealing with the quirks of certain browsers and degrading gracefully and dealing with fragmented platforms. In this tutorial, we’ll make a relatively simple game that takes you through the basics and steers you away from pitfalls. It’s a fairly simple game, in which the user bursts floating bubbles before they reach the top of the screen. We’ll develop this in a number of distinct stages: 1. Enough of the background story. As mentioned, there is a plethora of resolution sizes and pixel densities across devices. 2.

Technical Reference – Intel® HTML5 App Porter Tool - BETA , 2013. The Intel HTML5 App Porter Tool - BETA is no longer available. Legal Information Introduction The Intel® HTML5 App Porter Tool - BETA is an application that helps mobile application developers to port native Apple iOS* code into HTML5, by automatically converting portions of the original code into HTML5. It helps convert the following artifacts: Apple Objective-C* (and a subset of C) source code into JavaScript*Apple iOS API types and calls into JavaScript/HTML5 objects and callsLayouts of views inside Apple Xcode* Interface Builder (XIB) files into HTML + CSS filesApple Xcode project files into Microsoft Visual Studio* 2012 This document provides a high-level explanation about how the tool works and some details about supported features. How does it work? The Intel® HTML5 App Porter Tool - BETA is essentially a source-to-source converter that can handle a number of conversions from Objective-C into JavaScript/HTML5 including the conversion of APIs calls.

Apps | Mozilla Developer Network Learn how to create modern web apps using the latest web technologies and ideas — web apps that will have super powers in the latest modern browsers, but still provide an acceptable user experience in less able browsers. Modern app techniques Progressive web apps Progressive web apps involve taking standard web sites/apps that enjoy all the best parts of the Web — such as discoverability via search engines, being linkable via URLs, and working across multiple form factors — and supercharging them with modern APIs (such as Service Workers and Push) and features that confer other benefits more commonly attributed to native apps. App fundamentals The guides listed below cover common areas of functionality that you'll want to cover/implement in web apps. Quickstart This Quick Start guide introduces a recommended tool chain for creating web apps, and outlines the specific requirements for building Firefox OS applications.

Mobile Web API Evolution Ragavan Srinivasan’s post about the forthcoming Mozilla Marketplace for Open Web Apps inspired me to write about Mozilla’s surging Web and Device API standards work. A bit of background. Mozilla has always contributed to web standards, going back to the start of the project. We co-founded the WHAT-WG to kick off HTML5. As readers of this blog know, we are a leader in JS standardization. We have some of the top CSS and layout experts in the world. In the last eight months, our efforts to extend the web standards to include new APIs needed to build compelling apps and OS components on mobile devices have really caught fire. So I thought I would compile a list of emerging APIs to which we’ve contributed. The Mozilla contributions are worth noting both to acknowledge the individuals involved, and to highlight how Mozilla is championing device APIs for the web without having a native application stack blessed with such APIs on offer. Here is the list, starting with some 2011-era work: /be

getusermedia: Getting access to local devices that can generate multimedia streams 4. MediaStream API 4.1 Introduction The MediaStream interface is used to represent streams of media data, typically (but not necessarily) of audio and/or video content, e.g. from a local camera. Each MediaStream object can contain zero or more tracks, in particular audio and video tracks. Each track in a MediaStream object has a corresponding MediaStreamTrack object. A MediaStreamTrack represents content comprising one or more channels, where the channels have a defined well known relationship to each other (such as a stereo or 5.1 audio signal). A channel is the smallest unit considered in this API specification. A MediaStream object has an input and an output. Each track in a MediaStream object can be disabled, meaning that it is muted in the object's output. A MediaStream can be finished , indicating that its inputs have forever stopped providing data. The output of a MediaStream object MUST correspond to the tracks in its input. Both MediaStream and MediaStreamTrack objects can be cloned.
