# openfl-bitfive
OpenFL-bitfive is/was an alternative backend to OpenFL-html5, intended for usage with canvas-driven applications,
such as ones made with [HaxePunk](http://haxepunk.com/) or [HaxeFlixel](http://haxeflixel.com/) frameworks.
It features mostly custom code with several classes (most importantly number of `flash.net` ones and ByteArray) being taken from original [OpenFL-html5](https://github.com/openfl/openfl-html5).

The backend had a strong focus on performance and output sizes.

It was primarily used to port Flash-based web applications to HTML5,
though was also compatible with HaxePunk, HaxeFlixel, and other OpenFL-based framworks.

Development was eventually abandoned due to each new release of OpenFL making increasingly breaking changes to shared classes and the general custom backend mechanism, causing me to spend far more time updating the code for compatibility than I would spend on actual development.  
The last compatible releases are OpenFL 3.5.0, lime 2.8.0, and lime-tools 1.5.7.  
Also around this time HTML5 support in browsers started improving, so there was no longer a strong need for Flash fallbacks in web applications.

## Differences
A few to mention:
*	DisplayObject trees are presented as actual element trees with inheritance intact.
*	Optimized for performance and smaller "garbage generation" rates, where appropriate.
*	Completely rewritten BitmapData implementation. CopyPixels IS the fastest drawing method in many cases.
*	Slightly better compatibility across desktop and mobile browsers.
*	Easier to inspect DOM (see "node" property and variables while in Debug mode)

## Usage
Compiling (or at least trying to) your projects with openfl-bitfive is pretty straightforward:
1. Install the library via `haxelib install openfl-bitfive` or via `haxelib git`
2. Navigate to application.xml of your project and add the following before inclusion of OpenFL library:
   ```xml
   <set name="html5-backend" value="openfl-bitfive" />
   ```
   (note: if you have been previously using openfl-bitfive, make sure to remove a line including the
   library after OpenFL, or you'll be getting unusual errors since openfl 1.3.0/lime-tools 1.3.1)
3. Run the project. If everything was done right, first noticeable difference will be in stage background covering whole browser tab, as well as HTML elements forming a more common DOM tree and having "node" properties indicating their names in code (if ran in Debug mode).

For audio to work equally in all browsers, project should also include OGG versions of audio files (as opposed to MP3). This can be done with code like this:

```xml
<assets path="assets/snd" rename="snd" include="*.ogg" if="html5" />
```

## Notable incompatibilities
*	BitmapData and Graphics objects can only be bound to a single DisplayObject at time.
*	TextField-related classes are fairly draft. These will make attempts to display provided text anyway (for sake of compatibility), but they do not support embed fonts and most of needed properties.
*	HTML5 touch events are currently not being mapped to Flash touch events. Mouse events are mapped and dispatched fine though (including mapping of touch events into mouse events).
*	BitmapFilters are currently not implemented, but will be later on.

## License
Actually I was going to write a mixed licence that would seem more appropriate for library of this kind, but that has to be well-thought (and couple other factors), so there's MIT licence for time being:
