AS3 unFocus.HistoryKeeper in SVN trunk

Posted on by

I added an initial round of AS3 files to the SVN trunk to make HistoryKeeper more accessible from Actionscript 3.0. If you are feeling adventurous, feel free to check it out of the trunk, and give it a try.

There is also a small resurrected Actionscript to Javascript communicator (eh, it’s totally new actually, but I got to use old knowledge!). The theory is that if you use fscommand to send simple strings to Javascript, you save on Flash setting up a lock to wait for a Javascript call to return a value or finish executing, which should conceivably avoid a short hiccup in the Flash Player. I’m not sure if there’s a real world benefit or not yet – one day I might get around to testing to make sure. At the very least, this framework will make it easier to setup fscommand, since it takes care of creating the javascript snippet for you. After that, it will simply eval whatever you put in the command argument (unless it’s a simple function on window, then it’ll just execute that).

Any comments are welcome. Please note, these classes may change quite a bit, they’re not to be considered stable (though the API probably is, there’s not much there really).

MouseWheel on Mac

So for some reason MouseWheel.SCROLL events don’t work on Mac OS X. There is a fix! Gabriel over at Pixel Breaker created a script which fixes it up nicely.

The script did require some modification to get it to work with SwfHTML, since it was designed to work with SwfObject. It took very little modification to the JavaScript to make it work with any flash embedding script. The script has a register method that takes an id, and uses SwfObject’s getObjectById method to get the swf ref – I just changed the register method to take a swf reference instead of an id string, and viola! It works with anything now. While I was at it, I also took care of some errors you might get on non-mac browsers. Here’s how to use it:

// with SwfHTML
swfmacmousewheel.registerObject(
unFocus.SwfUtilities.getSwfReference("swfId")
);

// with SwfObject
swfmacmousewheel.registerObject(
SwfObject.getObjectById("swfId")
);

You can really use any method you want to get a reference to the swf object, and pass that in.

Here is the updated swfmacmousewheel javascript file. Note, you will still need to grab the source and follow the instructions from Pixel Breaker.

Quick Update – HistoryKeeper, SwfHTML, SwfShim

Just a quick post.

There have been a couple of fixes and changes that have gone into HistoryKeeper, SwfHTML and SwfShim that are now in the SVN trunk, as well as a few other issues that have been nailed down, and put into the issue tracker.

Among the fixes are finally a fix for the incorrect use of Javascript Errors in SwfHTML, as well as fixing the previously unfinished SwfShim.

Despite the fact that I can’t figure out how to pass flashvars from SwfShim to loaded AS3 based swfs, I’m still going to include it anyway, with a note about that caveat. It does solve some other issues, and adds an easy way to utilize ExpressInstall even if you are using html to embed the swf (rather than javascript). More on that in a future post.

I’ll also be cleaning house around the site, here and on google code. I’ve already removed some old lingering (and useless) ad stuff.

Also, since Microsoft removed the “click to activate” silliness, I went ahead and deprecated PatentMagic. It was buggy anyway.

Check back for more updates, and hopefully, an actual release!

A problem with Flash Player 10 version number and javascript detection

Posted on by

As you may have heard, Adobe recently released the first beta of Flash Player 10. It looks like unFocus.FlashPlayerInfo has been checking for single version digits, rather than multiple:

_versionRaw.match(/Shockwave Flash (\d)\.(\d)/);

The fix is easy enough (I could swear I actually fixed this at one point too):

_versionRaw.match(/Shockwave Flash (\d+)\.(\d+)/);

This problem doesn’t seem to be limited to just the unFocus Flash Detection script. I’ve seen other claims of failed Flash detection in other corners as well. I’d bet most of the problems are with the plugin detection scripts (Mozilla Firefox, Opera, Safari, etc.) and not with the ActiveX detection scripts (Internet Explorer), since most of the plugin detection scripts out there are using string parsing techniques, and have probably not tested with multiple digit Flash versions (since there haven’t been any until now).

I’ll see about getting a release out soon. If anyone needs any help updating anything, feel free to leave a comment, or email me.

unFocus.History Keeper 2.0 (and SwfHTML) Beta 2 – Out Now!

unFocus.History Keeper 2.0 Beta 2 is now available for download.

Feel free to download, test and use the new beta. Here’s what’s new and fixed:

  • History.js – There was an odd error, from a mixed up function, keeping History Keeper from working at all in the last release. It was the first issue reported by someone other than myself (thanks shacky7!) and it’s been fixed.
  • FlashPlayerInfo.js – was throwing an error if there was no flash player installed at all in IE. It’s fixed.
  • FlashPlayerInfo.js – added more robust Flash Player 6 detection. It is impossible to check for some minor revision versions in Flash Player 6, because they crash IE if you do. It’s now possible, though, to check for 6.0r65, which is the first version to support Express Install.
  • FlashPlayerInfo.js – deprecated “.getPluginType()”, and replaced it with “.getPlayerType()” and made it actually work. To practice discipline, I left “.getPluginType()” since it’s improper to change the API after a beta release (it didn’t work before, so I’m sure no one is using it).
  • FlashPlayerInfo.js – Fixed beta and MinorRevision errors in ActiveX path.
  • SwfHTML.js – was producing a security warning in IE if used over https. It’s fixed.
  • Added a bunch of test files for each object, to help make sure stuff doesn’t break (that’s annoying), and more thoroughly test the various methods and features. It is almost, sorta like unit testing, if you kinda look at it sideways, in a mirror. :-)
  • Added Object Patent Magic to the package.
  • Added SwfShim to the source (under javascript folder), but it’s not ready for prime time yet, and is not in the packed js file.
  • Added some example pages – but these are really just there to test to the packed files, at the moment. HistoryKeeper.html is a good place to start if you want to learn how to use History Keeper. I’ll update soon with some Flash examples.

Check out the updated project page for more info, or just skip straight to the download. :-)
