The Nintendo Wii is one of today's most popular console, with their control until then innovative for its release, became a video game "for family" and for various utilities. Today, the Nintendo Wii is used in various parts of the world not only for entertainment but also in areas such as physiotherapy for recovering patients :D

Today, the Nintendo Wii is used in various parts of the world not only for entertainment but also in areas such as physiotherapy for recovering patients :D

Well, we know it is possible to develop Flash for the Nintendo Wii, but we must observe some details first. Consider the specification of the Flash Player for the Nintendo Wii contained in Adobe Device Central CS5.

Specification Flash Player in Nintendo Wii


Note that we have to work with Flash Player 7, but Nintendo's website says it can be upgraded to Flash Player 8, and the application will run for the Wii browser, your browser is a version of Opera made exclusively for the Wii.
Wikipedia say that it updated Flash Player to Adobe Flash Lite 3.1 which corresponds to a full implementation of Adobe Flash version 8 with certain features of Flash Player 9. But i created a file Flash Player 9 with ActionScript 2.0 and it worked, Flash Player 9 with ActionScript 3.0 does not work and Flash Lite 3.1 worked. I stayed with Flash Player 9 with ActionScript 2.0 for my test. (System.capabilities.version show AFL 9,1,122,0)
Let's do an example first to see how is the operation of the Flash Player with the Wii Remote.

  • Create a new file type ActionScript 2.0 and soon after, put the movie to compile in Flash Player 8 or 9. Or you can do this directly through Adobe Device Central CS5, which leaves everything configured for you, including the size ideial to run on the Wii browser.
  • The purpose of this example is to evaluate the functioning of the buttons of the Wii Remote, create a symbol of type MovieClip.
  • Enter the following code in the movieclip so that our symbol can be dragged by the Wii Remote:
    PLAIN TEXT
    ACTIONSCRIPT:
    1. onClipEvent(mouseDown)
    2. {
    3.     this.startDrag();
    4. }
    5. onClipEvent(mouseUp)
    6. {
    7.     this.stopDrag();
    8. }

From what I understand, only in mouse events we can use the Nintendo Wii was not possible to use the other buttons and directional pad.
You can test the example by opening the following URL in the browser from the Wii http://www.leonardofranca.com.br/wii or watch the video below.

Despite the limitation of only using the mouse events, can you make very interesting applications in Flash for the Nintendo Wii. I leave a link with some games for the Nintendo Wii made in Flash. :D

Accelerometer is a motion sensor, one device responsible for measuring the relative positions of the axes x, y and z, ie, calculate the acceleration of the object. Today it is used for a variety of utilities such as: air bags, vibration measurement, measurement of inclination, smartphones, video games etc.

The accelerometer is used today is used for a variety of utilities such as: air bags, vibration measurement, measurement of inclination, smartphones, video games etc.

Flash Player 10.1 (only for mobile) and Flash Lite 4.0 have access to the device's accelerometer. I'm anxious to get their hands on a Nokia N8 to test new features Flash Lite 4.0, but this hard. Meanwhile, we are developing with Flash Lite 3.0 and 3.1.
Nokia has created a library especially for working with Flash Lite feature that gives access to natively are not possible as access to the accelerometer, GPS, calendar, contacts etc.

Nokia has created a library especially for working with Flash Lite feature that gives access to natively are not possible as access to the accelerometer, GPS, calendar, contacts etc.

I'll show a simple example of using the accelerometer with Flash Lite 3.0 and Nokia Platform Services.
Download the library Nokia and then save the directory under your operating system:

Nokia Platform Services only works on devices running Symbian S60 5th.

  • Mac - /Users//Library/Application/Support/Adobe/Flash CS5/en/Configuration/Classes/
  • Windows Vista - /Users//AppData/Local/Adobe/Flash CS4/en/Configuration/Classes.
  • Windows XP - //Local Settings/Application Data/Adobe/Flash CS5/en/Configuration/Classes/

We will start our first example:

  • Create a file of type ActionScript 2.0 and ask them to compile for Flash Lite 3.0 or 3.1. Or you can create directly from Adobe Device Central CS5.
  • Create a symbol of type MovieClip and give it the instance name of "ball_mc".
  • Create three text fields of type dynamic, therein are shown the positions x, y and z.
  • We must have a stage like this:

    Stage for test Accelerometer

This done, let's now part of programming:
We will start setting the stage for not changing the size of the application if the window is resized. The "DisableKeypadCompatibilityMode" is for use in smartphones with touch screens, if not used, the smartphone will automatically add the virtual keys corresponding to a non-touchscreen smartphone.

PLAIN TEXT
ACTIONSCRIPT:
  1. Stage.scaleMode = "noScale";
  2. Stage.align = "LT";
  3.  
  4. fscommand2("DisableKeypadCompatibilityMode");
  5. fscommand2("FullScreen", "true");

Now let's import the classes made by Nokia and use the Device class and disable the autorotation of the application.

PLAIN TEXT
ACTIONSCRIPT:
  1. import com.nokia.lib.Service;
  2. import com.nokia.lib.Device;
  3.  
  4. var deviceObject:Object = new Device();
  5. deviceObject.DisableAutoRotation(true);

Service will use the class by passing the parameter sensor and then passing the criterion for a search the coordinates of the accelerometer.

PLAIN TEXT
ACTIONSCRIPT:
  1. var sensors = new Service("Service.Sensor", "ISensor");
  2. var inParam = {SearchCriterion:"AccelerometerAxis"};
  3. var outParams = sensors.FindSensorChannel(inParam);

Will return a series of values we use to "advise" the smartphone that our application will be updated with every change in value of the coordinates of the accelerometer through a callback method.

PLAIN TEXT
ACTIONSCRIPT:
  1. var channelInfo = outParams.ReturnValue;
  2. var channelId = channelInfo[0].ChannelId;
  3. var contextType = channelInfo[0].ContextType;
  4. var quantity = channelInfo[0].Quantity;
  5. var channelType = channelInfo[0].ChannelType;
  6. var location = channelInfo[0].Location;
  7. var vendorId = channelInfo[0].VendorId;
  8. var dataItemSize = channelInfo[0].DataItemSize;
  9. var channelDataTypeId = channelInfo[0].ChannelDataTypeId;
  10. var channelParams = {ChannelId:channelId, ContextType:contextType, Quantity:quantity, ChannelType:channelType, Location:location, VendorId:vendorId, DataItemSize:dataItemSize, ChannelDataTypeId:channelDataTypeId};
  11.  
  12. var inParams = {ListeningType:"ChannelData", ChannelInfoMap:channelParams};
  13. sensors.RegisterForNotification(inParams, callBack);
  14. function callBack(transactionID:String, eventID:String, outParam:Object)
  15. {
  16.     if (outParam.ErrorCode == 0)
  17.     {
  18.         var channelData = outParam.ReturnValue;
  19.         txtX.text = channelData.XAxisData;
  20.         txtY.text = channelData.YAxisData;
  21.         txtZ.text = channelData.ZAxisData;
  22.        
  23.         xSpeed -= channelData.XAxisData/NOISE;
  24.         ySpeed += channelData.YAxisData/NOISE;
  25.     }
  26. }

Then just update the x and y coordinates with the values and xSpeed ySpeed in our MovieClip. Made available at the source code to define how far the MovieClip can walk, or only in the area of our application.

An interesting feature and that few people know the Flash Player or Adobe AIR, is that in addition to access features like the webcam user, it can also detect whether there is movement in the camera. This can be useful if you're implementing a system to stream live and want to save the bandwidth used. For example, the stream will only be published if you have any camera motion.

Flash Player or Adobe AIR, beyond access features such as webcam user can also detect whether there is movement in the camera.

Let's see an example using Adobe Flash Professional CS5 and Flash Builder 4 (using the Flex framework 4).

Adobe Flash Professional CS5

  • Create a file of type ActionScript 3.0
  • Press F11 to open the library, ask to create a new symbol type "video":

    Library->New Video

  • A new window appears, in the name of "cam" and leave the option "Video (ActionScript-controlled)" selected:

    cam

  • Drag the component you just created for the stage and the instance name of "cam", then resize to 320x240.
  • Drag a ProgressBar component's type library of the User Interface. Name the instance "pbar".
  • After that you should have something like this:

    Stage ready to start programming

We have our stage ready to start programming ActionScript 3.0. Let's start with asking the Flash Player to access the webcam and then put the image of the webcam in our component video.

PLAIN TEXT
ACTIONSCRIPT3:
  1. myCam = Camera.getCamera();
  2. cam.attachCamera(myCam);

Now just to make our movie listen to the event "ActivityEvent" Webcam.

PLAIN TEXT
ACTIONSCRIPT3:
  1. myCam.addEventListener(ActivityEvent.ACTIVITY,handlerMotion);

And handlerMotion method, we implement the actions in the ProgressBar.

PLAIN TEXT
ACTIONSCRIPT3:
  1. function handlerMotion(evt:ActivityEvent):void
  2. {
  3.     trace(evt.target.activityLevel);
  4.     pbar.setProgress(evt.target.activityLevel,100);
  5.     if(evt.target.activityLevel <10)
  6.     {
  7.         trace("muito quieto! =õ(");
  8.     }
  9.     else
  10.     {
  11.         trace("eba! festa!!! \\o/\\O/\\o/");
  12.     }
  13. }

See example in operation:

Adobe Flex 4
We will now see an example using Adobe Flex, I'll grab the camera using component VideoDisplay.

  • Create a project of type web (Flex) or Desktop (AIR).
  • Drag a component of type VideoDisplay and another type ProgressBar to the stage.
  • We have something like this:
    PLAIN TEXT
    MXML:
    1. <?xml version="1.0" encoding="utf-8"?>
    2. <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
    3.                xmlns:s="library://ns.adobe.com/flex/spark"
    4.                xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="450" minHeight="400" width="450" height="400">
    5.     <s:VideoDisplay id="cam" x="48" y="38" width="360" height="240"/>
    6.     <mx:ProgressBar id="pbar" x="125" y="297"/>
    7. </s:Application>

Simply implement the ActionScript programming now, is very similar to the way we did in Flash. We will change little in the ActionScript 3.0 code.

PLAIN TEXT
ACTIONSCRIPT3:
  1. protected function application1_creationCompleteHandler(event:FlexEvent):void
  2. {
  3.     pbar.mode = "manual";
  4.     myCam = Camera.getCamera();
  5.     var vd:Video = new Video(320,240);
  6.     vd.attachCamera(myCam);
  7.     cam.addChild(vd);
  8.     myCam.addEventListener(ActivityEvent.ACTIVITY, handlerMotion);
  9. }
  10.  
  11. private function handlerMotion(evt:ActivityEvent):void
  12. {
  13.     trace(evt.target.activityLevel);
  14.     pbar.setProgress(evt.target.activityLevel,100);
  15.     if(evt.target.activityLevel <10)
  16.     {
  17.         pbar.label = "muito quieto! =õ(";
  18.     }
  19.     else
  20.     {
  21.         pbar.label = "eba! festa!!! \\o/\\O/\\o/";
  22.     }
  23. }

Now, we only apply the logic to be transmitted or not the stream of the webcam user.

In Physics, kinematics is the branch responsible for studying the motion of bodies. Inverse Kinematics (IK) is a technique widely used in engineering, robotics and animation. It consists of the movement of an object or a set of objects in relation to other objects, using an articulated structure of bones. The bones allow the handling of complex and natural way possible to create character animation, such as arms, legs and facial expressions much more easily, the simplest image illustrates this is the movement of a lever. Anyone who has worked with 3D modeling software such as 3D Studio MAX already familiar with this technique. From Adobe Flash CS4, we have the opportunity to work with inverse kinematics in Flash IDE itself and a library in ActionScript 3.0.

Now let's see an example using Adobe Flash Professional CS5 will be pretty simple to understand the workings of this tool.

  • Create a new file type ActionScript 3.0
  • Create three graphic symbols in a rectangular shape so that the effect is better visualized. Let them side by side forming a row.
  • Select Bone tool
  • Click the first symbol of pure and drag until the end of it. Will be formed with a bone on its own biggest one being the base.
  • Do the same with the second symbol in order to start dragging from its own smaller bone of the first symbol.
  • Your stage should look like this:
    IK Adobe Flash

    IK Adobe Flash

  • Note that a new layer was created with the name of armature. Select frame 20 for example, right-click on the frame and select "Insert pose". This done, move in any way the symbols on the stage. Do the same for frame 40 and 60.
  • Now test the movie "Ctrl+Enter".

Desenvolvimento MobileThe mobile market is one of the fastest growing lately, and with it the demand for applications for this growing niche also bringing one more option for anyone who is a developer and new business opportunities. You developer who likes to keep up, you know exactly what I'm talking about. In this article I gathered some links that those who want to start with mobile development in at least three different platform in which I had lately demands.

The mobile market is one of the fastest growing lately, and with it the demand for applications for this growing niche also bringing one more option for anyone who is a developer and new business opportunities

Among the platforms available for mobile development, we can highlight:

  • Java with JME
  • Nokia Qt, besides being able to use WRT(Web RunTime)
  • Flash Lite
  • Android SDK from Google with the addition of Adobe AIR and Flash Player 10.1
  • IPhone

'll Comment a little bit of each:

Java with JME
JME (Java Micro Edition) is the version that Sun offers for you to program in Java for mobile devices. It offers an enormous range of API's that were made specifically. Has a very complete documentation and several examples. I leave a link how to set up your environment for development JME.

Nokia Qt
Nokia offers Qt, Cross-plaftorm application and UI framework, with specific libraries for mobile devices (such as QTMobility). You program in C++ and there is an interface language like MXML. Has its own IDE and has emulators for Symbian S60, 40 and Symbian^3 beyond Maemo and Meego.

Adobe Flash Lite
Adobe Flash Lite still has space on the market, with a different version of the Flash player with some features specific to mobile devices. The development environment is to own Adobe Flash Professional and Adobe Device Central.

Google Android
Google offers for the Android platform a set of SDK's and emulators for the different versions of its operating system with each passing day it becomes more popular. It has a plugin for you to program in Eclipse, the Android Development Tools(ADT). The language used is Java. From Android 2.2 (Froyo) you have the option to create applications in Adobe AIR, the AIR runtime is installed on the device and you create the application using Adobe Flash Professional (which has an extension to create the files .apk) or Adobe Flash Builder.

Apple IPhone
Who wants to program for iPhone, ipad and the like, Apple provides an SDK. You use the Objective-C language, derived from C, and some interesting libraries developed for working with muiltitouch like Cocoa. We'll find a list of frameworks.

Well, we have options, it behooves us to analyze only that can best serve our customers. Should stay something about Windows Phone 7 because it seems to me very promising and deserves attention too.

One of the questions you do lately is the possible death of Flash Lite. We have the Flash Player 10.1 optimized for mobile and Adobe AIR 2.5 for Android, and with that Flash Lite would be in their final days.
I've read articles that argued that Adobe did not know that capitalize on the success that Macromedia has with Flash Lite in Japan and began to give priority for mobile systems only now. This can be a little truth, but Adobe does not mess around, now this with full force for a variety of devices, not only mobile.
Now our question which gave title to the article, along with Flash Player 10.1, Adobe released Flash Lite 4.0 also, being a version of Flash Player for devices with limited processing resources and memory but with support for ActionScript 3.0. See the list of features available here.
For one thing, each day brings more smartphones come with Android 2.2 (Froyo), which officially supports the Flash Player 10.1 and Adobe AIR 2.5. Also, we're seeing with Android smartphones (earlier) being updated with Froyo. That is, based on Flash contents tends to grow with these major smartphones. On the other hand so far, have only a smartphone officially announced with Flash Lite 4.0, the Nokia N8 and possibly Nokia C7, the question remains, still worthwhile to develop content for Flash Lite?
And my answer is YES, even for Flash Lite 3.0 or 3.1(ActionScript 2.0) especially for Nokia devices and why I say this. Let's see some facts:

So in conclusion, is a market for development and yet it is worth studying (and remember) Actionscript 2.0. I believe that we will have two or three years of life for Flash Lite.

I was called to resolve a problem with the protection of the contents of a client, the problem was that somebody malicious was stealing their live streams.
He simply took the html code of the site and pasted on her website, so you may transmit the content in your blog. The player in question was not developed by me, so I did not even bother to look at the source, I decided to go directly to the Flash Media Server.
Based on the documentation from Adobe, I decided in a very simple code main.asc is as follows:

  51. };

The API Flash Media Server is very powerful and contains many interesting features, one of them is the ability to know where exactly the connection is coming from the swf. This passage has solved the problem with the constants declared at the beginning of the file.

PLAIN TEXT
JAVASCRIPT:
  1. if ((client.referrer == VALID_REFERRER && client.pageUrl == VALID_PAGEURL))
  2.     {
  3.         trace("acesso permitido");
  4.         application.acceptConnection(client);
  5.     }
  6.     else
  7.     {
  8.         trace("acesso indevido");
  9.         application.rejectConnection(client)
  10.     }

In short, so the connection is made with Flash Media Server is attempting to connect comes from a SWF and HTML defined by me.
A very simple solution but it solved the problem :D
As a last resort, the thief also copied the swf client and put into your blog :P

This post was originally written several years ago, it was only as a draft and strangely remains current.

Sometimes I see on the Internet some movement "anti-Flash", something really strange, it seems religion. There is a culture of saying that Flash is a program "to make a ball go" or that "Flash has accessibility zero, this is very far from the truth. it is possible to make extremely complex applications with Flash. And when there is a kind of "dispute" between AJAX X FLASH Flash x Silverlight Flash x HTML5. From time to time there is a new "Flash-killer", I think they are different technologies and complement. I see the same kind of radicalism in relation to PHP X Cold Fusion, ASP X PHP, PHP X PHYTON, Open Source X Proprietary etc.
I have also been very radical, defending PHP tooth and nail, spoke ill of any other language that was not PHP without even know it, but I realized that those who still think that way, limits their opportunities to major world today no matter what tool you use but how you use the tool, who heard "The bad employee blames his tools work"?.
Always worked with Flash and PHP, when I entered the BANCOOB, I felt compelled to learn Java, was a challenge that could overcome. Shortly after I entered the migration project, which would have to program in C # and Visual Basic, many of my friends simply do not accept into the project. I heard things like, "look at my curriculum and see if it is VB" and called the loose, but the end result was a great experience for me, I was able to grow much.
I have already been many philosophical discussions, and today I have no more patience for it when I see that this conversation tends to radicalism or religion, I lose the will to fully discuss.
Working with Flash since version 5, I followed closely the development of the tool, and the long ceased to be just a "plugin" to become a development platform for several devices. Of course with that, disrespect the competition, which is great. After all we must always move.

Developers who do not work with Flash, underestimate the power he has.

I'm not the only one who thinks this story that "one will replace the other" makes no sense, to own Adobe preaches that the two work perfectly together, so that the Adobe Dreamweaver CS5 already has support HTML5.
The launch of the iPad was the trigger for the so-called "anti-Flash". it mounted the perfect setting for a healthy discussion, where we could point out the strengths and weaknesses of a given technology and how it can be improved. But what we have seen is just the opposite, I've seen several articles and comments from people simply saying "I hate Flash", sites with sensational headlines(what they did to the post of Lee was disgusting!!!), Each week a different rumor that people believe without checking the sources and the same conversation 5 years ago.

Meanwhile, the client ta little matter if you use this tool or that, what matters to him is that you do the job.

The bad employee blames his tools work.

Flash Camp Brasil - I've been there!!!

Flash Camp Brasil - I've been there!!!


The event was unprecedented in Brazil, the Flash Camp Brasil, occurred in the last days 15 and 16 in Maceió, Brazil.
To begin with, was an adventure can go to the event, with tickets and expensive hotel crowded, but it is something that would not miss for the world.
I was staying in a hostel and lucky for me, on the morning of day 15, shared a post from the street, and my notebook with a damaged battery, I decided to go to the hotel of the event to familiarize myself with the way.
The path to the hostel to the hotel was closer than imagined, having only to wait anxiously for 7 hours until the event start.
While waiting and sitting on the couch with a provision making(ufa!!!), reunion the Gabriela Zaninetti, Marketing Manager of Adobe Systems Brasil, soon after going to the place of lecture and mini-courses, met Demian Borba was already in full swing in the last preparations for the event and introduced me to Filipe Cunha of Globo.com, sorry that did not to attend the mini-course it. Who was it was also Pedro Taranto(we almost ran into the airport).
Shortly after the Gabi introduced me to Fabricio Manzi, guy who knew the years and only in the event I can finally meet you in person. Then I had the opportunity to meet Tiago Venegas, with whom he later exchanged ideas on Flash Media Server, Cássio Souza, Technical Director Gringo and Diego of COC, after some talk time, arrivesIgor Costa, another so that the web and knew I had the opportunity to meet personally, I played a little Mortal Kombat vs DC Comics and took a beating by Neto Leal.
A few minutes before the event, entering the auditorium, reunion the Lee with whom I had a quick conversation about our trips were.
In between I had the opportunity to meet Beck Novaes, in which I showed a bit of a speech that would do the next day. At the end of the event, I know Bruno Ribeiro who told me about the project that won the mini ignite.

About the sessions
First day
Well, full auditorium, all fully prepared and Demian opened the event with an exciting presentation on EFM and how did your dream to make a Flash Camp in Brazil.

Joshua Hirsch Minister of Technology of the Big Spaceship, commented on how your company works and has demonstrated some very interesting projects in which the developer program so even in the latest stage of the project, first you need to buy a machine to smoke.

The second lecture was the Daniel Morena Creative Director of the Agency 32 Bits, about 1.0 Enhanced Reality, that really surprised me, systems showed he made a few years with the Flash Platform using multitouch when not imagined that. I could personally give my congratulations to Daniel Morena.

Second day
O segundo dia se iniciou com a palestra do Sam Rivello, CEO of RMC, biology compared with programming, demonstrated in a simple and objective simulation of biological behavior in programming in Flex 4.

The second lecture was that of Igor Costa, and relaxed and animated, it showed 40 differences considered significant change between Flex 3 and Flex 4.

Tiago Venegas began his lecture by explaining what's new in Flash Media Server 3.5, demonstrated vorttice, a tool conference that owes nothing to the Adobe Connect, also shown as is done dynamic stream.

Next, Lee explained some news about Flash Player 10.1 and created an example using the Adobe Flash CS5 exporting directly to a native application for IPhone.

The presentation of Cássio Souza began with a story about how the way you work in, then explained design pattern State Machine. You may have used State Machine and did not know.

Daniel Dura told the story of the multitouch and demonstrated how it can be worked in Flash Platform.

The talk of closure of the event was dedicated to the Beck Novaes about OutBox, and in my opinion, was closed on a high note, was simply fantastic, I think one of the best speeches of the event.

This was a summary on how fast it was my adventure in Flash Camp Brasil and the ultimate feeling is that it was very worthwhile, Maceió was perfect for the event and a cry marked the Flash Camp Brasil: "sa porra!!!".
