From AS2 to AS3 – Where did it go – setRGB

Update #1: It seems that .setRGB () has been deprecated in favor of the flash.geom.ColorTransform class. So a little as2 update.

In some cases I can’t help thinking that AS3 hasn’t made our live easier.
The same happened with the change that happened from the AS2 setRGB to AS3.

Specifies an RGB color for a Color object.

setRGB

This is what the ActionScript 2.0 Migration has to say about this:

ActionScript 2.0 ActionScript 3.0 Comments
setRGB() Method flash.geom.ColorTransform.color The RGB color value can be set by using the color accessor property of the ColorTransform class.

ActionScript 2 example code:
[as]
// AS2 Code
var my_color:Color = new Color(my_mc);
my_color.setRGB(0xFF0000); // my_mc turns red
[/as]

Another AS2 example because: “The Color class has been deprecated in favor of the flash.geom.ColorTransform class.”
[as]
// AS2 Code (The Color class has been deprecated in favor of the flash.geom.ColorTransform class.)
import flash.geom.ColorTransform;

var colorTrans:ColorTransform = new ColorTransform();
colorTrans.rgb = 0xFF0000;
var trans:Transform = new Transform( my_mc);
trans.colorTransform = colorTrans;[/as]

and the same code in ActionScript 3:
[as]
// AS3 code
import flash.geom.ColorTransform;

// Changes my_mc’s color to red.
var newColorTransform:ColorTransform = my_mc.transform.colorTransform;
newColorTransform.color = 0xff0000;
my_mc.transform.colorTransform = newColorTransform;
[/as]

More code to write, for something that I don’t use very much. The next time I need to change an Objects color I probably need to search the solution on the web…

No, I going to fix this in a neat little package:
Save this file into: ‘nl.matthijskamstra.utils’

And now I hope you will never have to look for it again
Happy AS3 😉

Lite components from BIT-101: Minimalcomps

Update #1: there has been another update New MinimalComp: WheelNav, but I’m pretty sure I won’t been using this one very much…

I’m using this for some time now, and it’s time to share this with you all: Minimalcomps from BIT-101.

This lite-weight components set is great, I can see what the code is doing, it’s easy to use and its simplicity is beautiful (and I love pixel font in Flash, I should use it more).

Minimal ActionScript 3.0 code only UI components

Do you need some reading material? Some documentation and introduction can be found on Keith Peters (BIT-101) site: read the first post about the Minimalcomps.

But in short:
This are some of the examples (since the first post there are some new components created, but they are not as frequently used as this set);

[swf]http://www.bit-101.com/minimalcomps/ComponentPlayground.swf, 500, 500[/swf]

For lazy readers (and a reminder for myself: the site of BIT-101 doesn’t have a very useful search, and the google code page doesn’t have documentation), here some code to create what you see above not entirely true, but I will keep the code here:
[as collapse=”true”]
var panel:Panel = new Panel(this, stage.stageWidth / 4, stage.stageHeight / 8);
panel.setSize(stage.stageWidth / 2, stage.stageHeight * 3 / 4);

var checkBox:CheckBox = new CheckBox(panel, 20, 20);
checkBox.label = &quot;Check it out!&quot;;

var label:Label = new Label(panel, 20, 40);
label.text = &quot;This is a label&quot;;

var pushbutton:PushButton = new PushButton(panel, 20, 60);
pushbutton.label = &quot;Push Me!&quot;;
pushbutton.width = 100;

var hSlider:HSlider = new HSlider(panel, 20, 90);
var vSlider:VSlider = new VSlider(panel, 130, 20);

var inputText:InputText = new InputText(panel, 20, 110);
inputText.text = &quot;Input Text&quot;;

var _progressBar:ProgressBar = new ProgressBar(panel, 20, 140);

var radio1:RadioButton = new RadioButton(panel, 20, 160);
radio1.label = &quot;Choice 1&quot;;
var radio2:RadioButton = new RadioButton(panel, 20, 180);
radio2.label = &quot;Choice 2&quot;;
var radio3:RadioButton = new RadioButton(panel, 20, 200);
radio3.label = &quot;Choice 3&quot;;

var colorchooser:ColorChooser = new ColorChooser(panel, 20, 230);
colorchooser.value = 0xff0000;
[/as]

This is the code you want to use, to create all the components (minus wheelnav… ) in a document class.

var _CheckBox:CheckBox = new CheckBox(panel, 20, 20, &quot;Check it out!&quot;);

var _Label:Label = new Label(panel, 20, 40, &quot;This is a label&quot;);

var _HUISlider:HUISlider = new HUISlider (panel, 20, 260, ‘HUISlider’);

var _InputText:InputText = new InputText(panel, 20, 110, &quot;Input Text&quot;);

var _ProgressBar:ProgressBar = new ProgressBar(panel, 20, 140);
//trace( &quot;_ProgressBar.maximum : &quot; + _ProgressBar.maximum );
_ProgressBar.value = .75;

var radio1:RadioButton = new RadioButton(panel, 20, 160, &quot;Choice 1&quot;, true);
var radio2:RadioButton = new RadioButton(panel, 20, 180, &quot;Choice 2&quot;);
var radio3:RadioButton = new RadioButton(panel, 20, 200, &quot;Choice 3&quot;);

var _ColorChooser:ColorChooser = new ColorChooser(panel, 20, 230, 0xff0000);

var _IndicatorLight:IndicatorLight = new IndicatorLight (panel, 250, 20, 0xff00ff, &quot;IndicatorLight&quot;);

var _Knob:Knob = new Knob (panel, 350, 20, &quot;Knob&quot;);

_Text.setSize (100, 50);

}

} // end class

} // end package
[/as]

And it quite easy to create buttons:
[as]
var myButton:PushButton = new PushButton(this, 10, 20, onClick);
function onClick (e:Event){
trace (‘onClick’);
// do something else
}
[/as]

You can download the MinimalComps set at: http://code.google.com/p/minimalcomps/
The set includes a CheckBox, PushButton, HSlider, VSlider, InputText, ProgressBar, RadioButton, ColorChooser (text input only) and Panel.

One big fat tip from me:
in the zip you will find a folder named ‘assets’ and in there is a truetype font called ‘pf_ronda_seven.ttf‘. You need to install that on your computer (Windows: C:\WINDOWS\Fonts , Apple: ??) and add it to your Flash file.

How to add a font to the Flash Library

Goto your library, add a “New Font”
Library add New Font
(sorry for the strange looking Flash, it has something to do with my screenshot programm)

Name: “PF Ronda Seven” (you need to spell this exactly as here, without the quotes (“))
Font: search for “PF Ronda Seven”, if you can’t find it, you probably need to restart Flash.
Size: 10

Font Symbol screen
(use this screenshot as an example if you don’t know what I mean)

You need to embed the font from the library into the .FLA : search the font you just created in the library and Right Click >> choose Linkage. Just check “Export for Actionscript” (“Export in first frame” will be activated to). I didn’t change anything, press “OK”

and you done!

Custmm Grumm – Selection tool

Custmm Grumm is a project that I will be working on in my spare time.
I will try to build a online tool for creating custom skins and modifying a Grumm.
It’s will be created in Flash (AS3).

The first research I did is selection, and how it works with shapes.
What it does:

  • select an item with one click
  • select an item by dragging (mouse down, mouse up)
  • select multiple items with dragging

What it doesn’t do:

  • shift add a selected item to the current selected items
  • shift click/drag deselect items

Custmm Grumm – The project

This will be my most ambitious project in my spare time: Custmm Grumm!

Custmm Grumm

What is Custmm Grumm?

When I created Grumm, I had no plans with the moody fellow. But after I got invited to participate in a book about papertoys I started to think about the future of papertoys (and Grumm).

Two of those thoughts about the future is the base of this project: you should be able to modify/create a papermodel without expensive software or specialized knowledge.

Papertoys are, more then vinyl toys, difficult to customize. You need knowledge of image or vector programs link Photoshop or Illustrator. Besides the knowledge of these programs, you also need the program them selfs, which is not cheap. Another bump in customizing is the flat version of the model: the simple papertoys are not that difficult to understand, but the more complex models with more parts, it’s difficult to know which part goes where and how it will look.
It would be nice that you could create a custom skin and modify the model yourself.

Creating a custom skin for a model is done before: papercritters but modifying the model to isn’t.

I will try to make Custmm Grumm in Flash (AS3) so that it’s possible to create a custom skin and modify the model (with some restrictions of course)…

I had a discussion about this project on Nice Paper Toys if you want to know some more about the rocky start of this project.

AS2 to AS3: get all objects in a movieclip

Sometimes you want a list of everything inside a movieclip. For example: you want to know the instance names of every movie in the root.

ActionScript 2

A little trick that I used a lot in AS2 is:

for(var i in _root){
   trace('key: ' + i + ', value: ' + _root[i]);
}

or

for(var i in target_mc){
   trace('key: ' + i + ', value: ' + target_mc[i]);
}

to find out which movies are in target_mc

It was not only a trick to trace everything, I also used it to reset movieclips (place them outside the stage, or delete them) or quickly make buttons out of them:

for(var i in target_mc){
	target_mc[i].id = i;
	target_mc[i].onRelease = function (){
		trace ("id = " + this.id); // onRelease the id will be called (the name of the movie)
	};
}

ActionScript 3

But in AS3 this doesn’t work any more!
And I know: AS3 should make my life easier…. well if I see the solution to the problem created by AS3, I have to disagree!

for (var i:uint = 0; i < target_mc.numChildren; i++){
	trace ('\t|\t ' +i+'.\t name:' + target_mc.getChildAt(i).name + '\t type:' + typeof (target_mc.getChildAt(i))+ '\t' + target_mc.getChildAt(i));
}

In AS3 you first have to get the "number of children" (numChildren) in a DisplayObjectContainer, then you have to say which child you want (getChildAt(i))...
A good thing about AS3 is, you get everything in a movieClip, even shapes you made there without a instance name.

I'm glad that I work with FlashDevelop, which has snippets so I don't have to type this constantly!

(For the people that use FlashDevelop too, here is my snippet:)

// $(Clipboard)is a DisplayObject
trace ('+ number of DisplayObject: ' + $(Clipboard).numChildren + '  --------------------------------');
for (var i:uint = 0; i < $(Clipboard).numChildren; i++){
	trace ('\t|\t ' +i+'.\t name:' + $(Clipboard).getChildAt(i).name + '\t type:' + typeof ($(Clipboard).getChildAt(i))+ '\t' + $(Clipboard).getChildAt(i));
}
trace ('\t+ --------------------------------------------------------------------------------------');

From AS2 to AS3 – Where did it go – onRelease

Last year I started working with AS3, and after having some startup problems, I’ve made my first application in it (not online yet).
The strange thing is, I started a new project and when I had to make a button from a movieclip, I immediately wrote it in AS2… 🙁

That AS2 is embedded deep into my brain and probably more people have this problem.
So I started this series of post about the stuff that’s changed in from AS2 to AS3.

I will probably regurgitate what other people already wrote something about, but it’s my “travel” trough AS3 land.

onRelease

One of things I use in every application that I build is onRelease.

This is what the ActionScript 2.0 Migration has to say about this:

ActionScript 2.0 ActionScript 3.0 Comments
onRelease() EventHandler flash.display.InteractiveObject dispatches event: mouseUp Replaced in the new event model by a mouseUp event.

In AS2 I know 3 ways to use it:

AS3 – take one step at a time: step 1a

I’ve made a mistake, the code I original wrote doesn’t work (I’m glad nobody noticed it 😉 ). You can find the correct class here

My previous post is about my first step into ActionScript 3 (AS3) and in my case: trail and error is the best way to learn stuff.

But it takes some time to find out and sometimes it’s nice to have some help.

I found some help to fix this in the future : Patrick Mineault at 5 1/2 blog has created a AS2 to AS3 converter which you can test here and download here.

There is a web form to paste your code into and it will return your converted AS3 code (check it here).
There is also an command line exe in the zip file
I’m not very good at command line, so for your (and mine) convenience I will explain how to get the exe to work with a .BAT file (I work on a PC so the example only works on PC).

Download the zip file and extract it somewhere on your computer. In my case C:\tmp\convert
I’ve created to folders in the convert folder
C:\tmp\convert\input
C:\tmp\convert\output

and in the input folder I copied all the classes I’ve ever written.

Now create a file with a .BAT extension (in my case convert.bat) and it doesn’t matter where you put it, but I put it next to the convertas2as3.exe in C:\tmp\convert folder.

Open the file you just created and paste this in there:

pause
C:\tmp\convert\convertas2as3.exe -input "C:\tmp\convert\input" -output "C:\tmp\convert\output"

or adjust the path to the files you want to convert
save the file and open the .BAT file (in my case convert.bat) and all your classes you ever have written are converted to AS3…

Well as good as it get’s: it’s not 100 percent converted to AS3 but it helps you with most of your code, and helps you on your way to find the correct code.

example
take the code I translated in the previous post but now in a class file:

class nl.matthijskamstra.config.ConfigFile
{
	/**
	* Constructor 
	* To access and manipulate information about the boundaries of a SWF file.
	*/
	public function ConfigFile ()
	{
		// trace ("set flash to 'browser'-mode");
		_root._quality = "BEST";
		Stage.scaleMode = "noScale";
		Stage.showMenu = false;
		Stage.align = "TL";
	}
	/**
	* static function config.... same as above
	*
	* @usage   nl.matthijskamstra.config.ConfigFile.config ();
	*/
	static function config () : Void
	{
		var temp = new nl.matthijskamstra.config.ConfigFile ();
	}
}

and put it through the AS2 to AS3 online converter will become:

package  { 
class nl.matthijskamstra.config.ConfigFile
	import flash.ui.ContextMenu;
	import flash.display.Stage;
	{
		/**
		* Constructor 
		* To access and manipulate information about the boundaries of a SWF file.
		*/
		public function ConfigFile ()
		{
			// trace ("set flash to 'browser'-mode");
			_root._quality = "BEST";
			Stage.scaleMode = "noScale";
			Stage.showDefaultContextMenu = false;
			stage.align = "TL";
		}
		/**
		* static function config.... same as above
		*
		* @usage   nl.matthijskamstra.config.ConfigFile.config ();
		*/
		static public function config () : void
		{
			var temp = new nl.matthijskamstra.config.ConfigFile ();
		}
	}
	
}

this will not work without errors but will help you convert your AS2 code to AS3

package nl.matthijskamstra.config {

	import flash.display.MovieClip;	
	import flash.display.Stage;
	import flash.display.StageQuality;

	public class ConfigFile extends MovieClip {
		/**
		* Constructor 
		* To access and manipulate information about the boundaries of a SWF file.
		*/
		public function ConfigFile () {
			trace ('ConfigFile ')
			stage.quality = StageQuality.BEST;
			stage.scaleMode = "noScale";
			stage.showDefaultContextMenu = false;
			stage.align = "TL";
		}
		/**
		* static function config.... same as above
		*
		* @usage   nl.matthijskamstra.config.ConfigFile.config ();
		*/
		static public function config () : void
		{
			var temp = new nl.matthijskamstra.config.ConfigFile ();
		}		
	}

	
}

The config class that works!
package nl.matthijskamstra.config {
	
	import flash.display.MovieClip;	
	import flash.display.StageQuality;

	public class ConfigFile extends MovieClip {
		
		// Constants:
		public static var CLASS_REF = nl.matthijskamstra.config.ConfigFile;
		public static var CLASS_NAME : String = "ConfigFile";
		public static var LINKAGE_ID : String = "nl.matthijskamstra.config.ConfigFile";
		
		/**
		* Constructor
		* 
		* @usage   	import nl.matthijskamstra.config.ConfigFile; // import
		*			var __ConfigFile__ : ConfigFile = new ConfigFile ( this );
		* @param	$target_mc		a reference to a movie clip or object
		*/
		public function ConfigFile( $target_mc:MovieClip = null ) {
			// trace ( '+ ' + LINKAGE_ID + ' class instantiated');
			$target_mc.stage.quality = StageQuality.BEST;
			$target_mc.stage.scaleMode = "noScale";
			$target_mc.stage.showDefaultContextMenu = false;
			$target_mc.stage.align = "TL";
		}
		
		/**
		* static function config.... same as above
		*
		* @usage  	nl.matthijskamstra.config.ConfigFile.config(this);
		* 			ConfigFile.config (this);
		* @param	$target_mc		a reference to a movie clip or object	
		*/
		static public function config ($target_mc:MovieClip ) : void {
			var __config = new nl.matthijskamstra.config.ConfigFile ($target_mc);
		}
		
	} // end class
	
} // end package

I’m sorry for adding to the confusion which happens when you learn ActionScript 3!
The Stage class is a difficult change from AS2 to AS3, when I have some time I will explain.

AS3 – take one step at a time: step 1

I finally started programming with ActionScript 3 (AS3); I know, I not a early adopter… 😉

And the first steps in AS3 are as uncomfortable as the first time I started OOP programming … or when I started moved from AS1 to AS2…

Since I started working for NOISE 5 months ago and moved to Amsterdam, I haven’t had time to do learn AS3.
That luckily has changed 🙂 and I started learning the basics.

And the first obstacle I ran into was something very simple: I always use a basic document (FLA) with default library items, some layers I always use and some ActionScript code to align the stage:

_root._quality = "BEST";
Stage.scaleMode = "noScale";
Stage.showMenu = false;
Stage.align = "TL";
stop ();

I have this also in a class (AS2), so I thought it would be useful to rewrite this class in AS3.
and I wanted to use this in my new as3 files too… (remember that this is the first thing a tried)

First you need to create a document class:

Document Class
And in my case my document class was: ‘Main’


package  {

	public class Main {
		
		public function Main() {
			trace ('Main')			
		}
		
	}
	
}

(package generated by FlashDevelop)

Code didn’t pass; I got a Compiler Error:
5000: The class 'Main' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type.


package  {

	public class Main extends MovieClip {
		
		public function Main() {
			trace ('Main')			
		}
		
	}
	
}

I got some new errors:

  1. 1017: The definition of base class MovieClip was not found.
  2. 5000: The class ‘Main’ must subclass ‘flash.display.MovieClip’ since it is linked to a library symbol of that type.

So I added import flash.display.MovieClip;


package  {

	import flash.display.MovieClip;
	
	public class Main extends MovieClip {
		
		public function Main() {
			trace ('Main')
		}
		
	}
	
}

Ahhh and now we can get the stage to work with my ‘old code’, let’s paste it into the new document:


package  {

	import flash.display.MovieClip;
	
	public class Main extends MovieClip {
		
		public function Main() {
			trace ('Main')
			_root._quality = "BEST";
			Stage.scaleMode = "noScale";
			Stage.showMenu = false;
			Stage.align = "TL";
			
		}
		
	}
	
}

Auw: both _root and Stage doesn’t excited no more: I got an migration error


package  {

	import flash.display.MovieClip;	
	import flash.display.Stage;
	import flash.display.StageQuality;
	
	public class Main extends MovieClip {
		
		public function Main() {
			trace ('Main')
			stage.quality = StageQuality.BEST;
			stage.scaleMode = "noScale";
			stage.showDefaultContextMenu = false;
			stage.align = "TL";
		}
		
	}
	
}

And at last it works…
The only thing now to do, is to put it in the correct package.
