Anti-fungal And Parasites Lotrisone Cream In 20gr Tube (Generic) $101.00

ActionScript 3.0 Flash

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 Last year around this time, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 I described how to pass variables into a SWF by way of something called FlashVars.  This was discussed in “How to Tell a SWF What File(s) to Load — From the Outside” which works for pretty much any sort of simple data you may want to pass in, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 as long as you’re talking about relatively small groups of name/value pairs.  Complex data is more likely to be suited to XML.  In that earlier blog entry, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the purpose was to re-use a single SWF numerous times to load a variety of MP3 files, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 by specifying which audio in the HTML.  Pretty flexible solution!  You could use the same technique for loading JPGs or FLVs, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 to populate dynamic text fields, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 or whatever you like.  The article has been fairly popular and continues to be useful — as long as your SWF is published for ActionScript 2.0 (or even 1.0 if you drop the post colon suffixes — :String, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 :Number, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 and the like).  In ActionScript 3.0, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 things are different. 

The updated code

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 There are two halves to getting this sort variable into Flash:  the HTML side and the ActionScript side.  Fortunately, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the HTML side hasn’t changed at all.  Even with an ActionScript 3.0 SWF, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 you can read the existing “From the Outside” article and continue to follow the instructions as stated, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 even for the SWFObject (JavaScript embedded SWF) section at the end.  The difference comes within the first few paragraphs on ActionScript 2.0.  And even so, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the code as shown in that article …

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 But clearly, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 this approach is hard coded. Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00  In order to open up the possibilities, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 replace the path reference with a variable — let’s just call it audio.

var s:Sound = new Sound();
iconButton.onRelease = function():Void {
 s.loadAudio(audio, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 true);
}

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 … comes fairly close to the updated syntax.

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 In ActionScript 3.0, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 incoming FlashVars variables are no longer available as a loose collection in the main timeline.  In the above AS2 code, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the audio variable is passed in to the SWF from the HTML document and is therefore not declared in the movie.  In AS3, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 such variables have been moved to the parameters property of a LoaderInfo instance associated with the main timeline.  The LoaderInfo class “provides information about a loaded SWF file or a loaded image file (JPEG, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 GIF, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 or PNG). Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00  LoaderInfo objects are available for any display object [this means instances of the DisplayObject class, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 which includes movie clips]. Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00  The information provided includes load progress, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the URLs of the loader and loaded content, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the number of bytes total for the media, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 and the nominal height and width of the media.” source

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 To get to the LoaderInfo instance associated with the main timeline, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 you may refer to the DisplayObject.loaderInfo property of the main timeline.  Remember, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the main timeline is a descendent of the DisplayObject class; it can be treated as a movie clip (an instance of the MovieClip class) or a sprite (an instance of the new Sprite class) — but we don’t need to worry about that here.  The punch line is simply that instances of DisplayObject have a loaderInfo property that points to their own private instance of LoaderInfo, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 and LoaderInfo instances have a parameters property.  To update the above AS2 code, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 then, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 swap out the solitary audio variable with the expression root.loaderInfo.parameters.audio.  The name of the variable is the same, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 assuming FlashVars specifies it as “audio.”  Here it is in context:

var s:Sound = new Sound();
iconButton.onRelease = function():Void {
 s.loadAudio(root.loaderInfo.parameters.audio, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 true);
}

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 Now, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 even with that change, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 the above code would fail in ActionScript 3.0.  Why?  Because AS3’s event handler model is completely overhauled.  Button instances, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 like the above iconButton, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 no longer use onRelease as shown, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 plus the Sound class behaves differently.  Here’s the same brief code in AS3:

var s:Sound = new Sound();
iconButton.addEventListener(
 MouseEvent.MOUSE_UP, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00
 function(evt:MouseEvent):void {
  s.load(new URLRequest(root.loaderInfo.parameters.audio));
  s.play();
 }
);

Anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 But that isn’t the important part, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 because ultimately, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 what you do with passed-in variables is up to you.  The key is how to access them, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 and the solution is root.loaderInfo.parameters, anti-fungal and parasites lotrisone cream in 20gr tube (generic) $101.00 followed by a dot and the name of whatever variable you’re after.  This variable will have been passed into Flash by way of the FlashVars attribute of your HTML’s <object> and/or <embed> tag(s).
