Web and Mobile Development articles
So you made your game or some other app that has multiple sound effects produced by several audio files. It works great on your desktop, laptop, etc. browsers but then you realize that you have some major issues with multiple sounds (or even single) on mobile and tablet platforms like iOS and android browsers. Sad!

In one of my earlier posts I discussed some of the issues (or limitations) with HTML5 audio support in iOS and Android mobile and tablet platforms. In this article I am going to try to take a look at some of the ways we can overcome those limitations and quirks.
Few months back I was developing an HTML5 game where I really struggled with adding and playing the different sound/audio effects properly across different browsers and platforms, especially in mobiles and tablets. As I made some progress, I decided to document the support and behaviour of HTML5 Audio in mobile environments – iOS and Android – based on my trials.

I am going to share a neat little trick that was learnt while working on an HTML5 game recently. The game is pretty much like our HTML5 Doodle Jump. We had to make sure that the game scales down very well on smaller devices like mobiles, ipads, tablets, etc. and in the process learnt a neat trick to scale the entire canvas across all devices consistently.

Few days ago, I wrote a post about why time based animations are better than frame based animations. However, in animations done as a function of time, some serious problems could arise. One of them is that your regular collision detection techniques might fail if the frame rate is lower than acceptable. Your object might pass through the walls or even fall through the floor!
So you got into Web Based Animations or Games (using that HTML5 thingie) and chances are high that you’re relying on setInterval, setTimeout or even better – requestAnimationFrame to reflow and repaint your frames (fancy terms for rendering each animation frame). Precisely, you’re basing your animations or game mechanics on the frame rate. There’s nothing wrong with that, but let me show you a more sophisticated approach which can actually enhance all sorts of user experience – time based animations.

Limiting the frame rate while using requestAnimationFrame can be a common want especially when coding Games where you want your animations and mechanics to not exceed a particular mark of frames per second. Let’s go through 2 ways of doing it.
