This reverts commit dd1e0cc.

This was merged but just found that it breaks the experimental-demo-tlos
enemies bouncing when hit, so I'm reverting until we find what was
causing the problem.
Latest commit 052d86c Dec 12, 2012



Akihabara is a set of libraries, tools and presets to create pixelated indie-style 8/16-bit era games in Javascript that runs in your browser without any Flash plugin, making use of a small small small subset of the HTML5 features, that are actually available on many modern browsers.

Notes about audio features

  • Audio compatibility is Work in progress
  • Firefox stable has little audio caching problem/slowdowns and sometime freezes - can't figure out if is plugin's fault. Seems fixed on nightly builds. Audio is not marked as experimental.
  • For compatibility with Safari, every audio file used for games MUST be more than 1.5 seconds long. Add silence to reach the 1.5secs length.
  • Safari is having troubles on downloading audio for unknown reasons. Seems fixed on nightly builds. For now AUDIO IS EXPERIMENTAL.

Notes for developers

  • For maximum compatibility make sure that you're using the ["name"] for when setting object properties with reserved names like "goto" and "data" (Discovered during patching for Wii)
  • Also do not use the comma after the last element of an array or a property of an object. Still work on many browsers but is broken for Opera Wii. (and probably IE, when will be supported)
  • For making sure that your sub-scripts are loaded, try to add an "alert" at the end. Opera for Wii silently fail when there are syntax errors like the one explained before.
  • Opera Wii wants that canvas have to be blitted at least once before being used - or fails with a browser crash! The built-in gbox.createCanvas was already fixed. Is a good thing to use that method for spawning canvas.
