StageWebViewBridge Update

xperiments — Sun, 22 Jan 2012 00:00:29 +0000

I have updated the StageWebViewBridge class to fix some errors as the 5.0. doNotBackup directive problem…

See more a the projects page at http://code.google.com/p/stagewebviewbridge/

StageWebViewBridge. Updated. Automatic cache creation.

admin — Wed, 06 Apr 2011 01:42:30 +0000

StageWebViewBridge class was upgraded with new features for managing files in the cache.

With the new system it is possible to forget if a cached file is updated, the system does everything for us and finally we get 2 output directories. These 2 directories are the directories we must include in our final package release.

The new methods and properties:

1 2	// sets Debug mode on/off StageWebViewBridge.DEBUGMODE = true/false;

1
2
3
4
5
6

// sets the default dir to 'htmlFiles'
StageWebViewBridge.setRootFolder('htmlFiles');

// this will create 2 new dirs
app:/htmlFilesCache
app:/htmlFilesSource

1
2
3
4
5

// Change the extensions of the files to parse.
// Default extensions are ["html","htm","css","js"]

// now limit the files to be html or js, and left intact the css and htm files
StageWebViewBridge.setSourceFileExtensions(['html','js']);

StageWebView StageWebViewBridge Communicating between actionscript and javascript and vice versa

admin — Sat, 26 Mar 2011 19:56:49 +0000

I have made an extended StageWebView Class that lets you:

* Communicate Actionscript with Javascript.
* Communicate Javascript with Actionscript.
* Load local files and resources in a easy way.
* Extend loadString method with AS3 – JS communication.

By example you can call javascript from as3

1 2	// call javascript with callack function webView.bridge.call('someFunctionToCall', callBackFunction, ...arguments );

// reference local resources in a easy way

OSX 5005:Unknown error optimizing byte code

admin — Tue, 31 Aug 2010 12:29:55 +0000

Working in a large AIR project, the flash compiler give me this strange error:

1	5005:Unknown error optimizing byte code

To avoid it , we must increase the memory of the compilator by creating a file in:

1	~/.MacOSX/environment.plist

and put this text in it:

1
2
3
4
5
6
7
8

JAVA_TOOL_OPTIONS
-Xmx512m

If you use flash CS5 also edit this file:

1	~/Library/Application Support/Adobe/Flash CS5/en_US/Configuration/ActionScript3.0/jvm.ini

Then change -Xmx128m to -Xmx512m

AS3 Condicional Switch Stament

admin — Wed, 28 Apr 2010 15:55:37 +0000

Imagine we can use switch staments with conditional operators other then strict equality.

This way we can do a code like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18

var value:int = 2;
switch(value){
case < 1:
trace("Value is less than 1");
break;
case 2:
trace("Value definitely equals 2");
break;
case >= 3:
trace("Value is greater than or equal to 3");
break;
case > 1 && < 3:
trace("Value is greater than 3 and less than 5");
break;
case !== 5:
trace("Value definitely doesn't equal 5");
break;
}

Navigating the web I have find one solution:

1
2
3
4
5
6
7

9
10
11
12

var value:int = 2;
switch (true) {
case value < 1:
trace("Value is less than 1");
break;
case value == 1:
trace("Value equals 1");
break;
case value > 1:
trace("Value is greater than 1");
break;
}

Dynamically create instance of Vector class

admin — Thu, 08 Apr 2010 14:39:12 +0000

AS3 don’t let us dynamically create an instance of class Vector with elements of various types, the solution is use getDefinitionByName.

package
{
import flash.system.ApplicationDomain;
import flash.utils.getQualifiedClassName;

public class ClassUtils
{
static private const VECTOR_CLASS_NAME : String = getQualifiedClassName( Vector );

static public function getVectorDefinition(itemDefinition : Class, applicationDomain : ApplicationDomain = null) : Class
{
if(!applicationDomain) applicationDomain = ApplicationDomain.currentDomain;
return applicationDomain.getDefinition( VECTOR_CLASS_NAME + '.<' + getQualifiedClassName( itemDefinition ) + '>' ) as Class;
}
static public function createCustomVector(itemDefinition : Class, length : uint = 0, fixed : Boolean = false, applicationDomain : ApplicationDomain = null) : Vector.<*>
{
var definition : Class = getVectorDefinition( itemDefinition, applicationDomain );
return new definition( length, fixed );
}
}
}

To get definition of Vector class with specified item type:

1
2
3
4

var itemType:Class = Sprite;
var definition:Class = ClassUtils.getVectorDefinition(itemType);
trace(definition); // [class Vector.]
trace(getQualifiedClassName(definition)); // __AS3__.vec::Vector.

To create Vector class instance with specified item type:

1
2
3

var itemType:Class = Sprite;
var vector:Vector.<*> = ClassUtils.createCustomVector(itemType);
trace(getQualifiedClassName(vector)); // __AS3__.vec::Vector.

AS3 Differents approaches for image format read/write.
