SoundJS 0.5.2 Audio Plugin for CocoonJS 1.4.7

Posted on March 30, 2014 by olsn

I just updated the CocoonJSAudioPlugin.js to work with SoundJS 0.5.2 and CocoonJS 1.4.7

How to use: Just put the CocoonPlugin as the first entry to register and you can use everything else of the SoundJS-library just as is in CocoonJS now.

 createjs.Sound.registerPlugins([createjs.CocoonJSAudioPlugin]);

1	createjs.Sound.registerPlugins([createjs.CocoonJSAudioPlugin]);

Playing the same sound multiple times parallel/overlapping: You will have to set the maximum number of parallel sounds in the register-method:

  //this will allow me to play 3 parallel instances of jump.ogg
  createjs.Sound.registerSound('jump.ogg','jump', 3);

1 2	//this will allow me to play 3 parallel instances of jump.ogg createjs.Sound.registerSound('jump.ogg','jump', 3);

I have been very busy recently and I am now starting to catch up with the blog and everything.

But the reason for this post is that I want to write about another indie game that friends of mine are currently developing called ‘Commander Cherry’s Puzzled Journey’.

Posted on September 15, 2013 by olsn

This week I’ve finished my entry for the JS13k Compo – a competition for HTML5-games with a size<=13kb (zipped) - my entry is a multiplayer-game, kind of like "Plants vs. Zombies" for two players. And I'm very proud of my accomplishment of keeping the size of server+client combined down to 12kb (zipped) You can check out the source-code at: https://github.com/olsn/qmarks

Fading Waves Effect with EaselJS

Posted on May 15, 2013 by olsn

Today I made a basic JavaScript-version of my flash waves-effect, that I made a couple years back.

For bluring I used this filter: Link – but still: For those kind of operations HTML/JS is unfortunately still way behind flash in terms of performance.

The state of Audio in HTML5 Games

Posted on April 26, 2013 by olsn

HTML5 Gaming for desktop and mobile is a very trendy topic these days. The performance of canvas applications is getting better and better each day and technologies like CocoonJS or Ejecta even enable a close to native performance for canvas applications on mobile devices. – But what about audio? Is it really that easy to implement sound with your html app?
This article features some interesting points that I collected while researching for my eBook ‘From Zero to the Appstore’.

Audio != Audio

While most browsers and devices already do support audio in general, that doesn’t mean you can just play any audio file in any modern browser. The following table briefly lists the support for Audio-codecs.
