Speaking at IGDA Switzerland 25th february 2010

pigiuz — Mon, 08 Feb 2010 09:25:56 +0000

I’ll be speaking at IGDA Switzerland in Bern in few weeks,

a great opportunity for me to talk about the Flash Platform as a gaming platform, to share the experience I had making the engine of Wazzamba and to meet new people I only “met” in twitter or in their blogs

The meeting will take place in february 25th at “Nothing” (great name guys ) hq in Wabern, you can find more info here in IGDA Switzerland blog.
See you there

BitmapData manipulation benchmark

pigiuz — Wed, 15 Jul 2009 19:54:49 +0000

Today I encountered this blog post from Zevan (which blog is REALLY a good daily reading I suggest everyone to take) about bitmapData merging and I started tweaking some code doing some benchmarks to find out which way is the most performing. Here are my tests:

First strike (Zevan’s one): copyPixels

in my machine (mbp, osx) it takes ~27 ms to extract data and ~2-3ms each iteration for setting data on the canvas bitmapData

Second strike: getVector\setVector

on my machine it takes only ~9 ms to extract tiles slices (yes, 3 times faster!!!) and ~1ms for pushing them all in the canvas for each loop iteration

a nice one, ~ 17 ms to extract and ~2ms to loop on my mac, faster than copyPixels but vectors are still leading…

}

~36 ms to extract and ~12ms to merge tiles on the canvas!!!…too slow all the way…:\

There are still some methods left such as getPixel\setPixel, getPixel32\setPixel32, and copyChannel but they’re a too much restrictive choice because they’re handling one pixel, or channel at time therefore a further loop would be required to get them doing this task.

Summary:
getVector\setVector : ~9ms\~1ms
getPixels\setPixels: ~17ms\~2ms
copyPixels: ~27ms\~2-3ms
merge: ~36ms\~12ms

make your choice

NOTE: these benchmarks are valid from flash player 10 because we (both me and Zevan) used the Vector native type to store lists of typed data. To make them valid for previous version of the player make sure to replace vectors with arrays and check other types are already supported by the target player.

stay tuned

My entry to Bit-101s 25 Lines competition

pigiuz — Sun, 30 Nov 2008 13:45:08 +0000

Yep, i made my submission to 25lines contest just few days ago (right in time ), so (as Sakri did some days before me) I’m publishing my code. It’s an easy terrain generator…

Actually, I think it can be somehow improved both in lines of code and actual performances, so feel free to edit or tell me “you’d better to do that this other way…”

What’s going on is:

generate a shape filled with a gradient to create a reference color for differents “height”
generate a perlinNoise everyframe for dataprovider use
detect each perlinNoise pixel depth according with its main channel value (blue in this case..)
generating a vector of Bitmaps to be employed in the view

Flash Player 10 API docs ready for download

pigiuz — Thu, 22 May 2008 20:09:47 +0000

Here’s the link to download Astro’s API documentation: http://download.macromedia.com/pub/labs/flashplayer10/flashplayer10_as3langref_052008.zip

At this time it’s only available for download, not for online consultation.

Flash player 10 available on Adobe Labs

pigiuz — Fri, 16 May 2008 00:35:44 +0000

It’s time to upgrade!
Astro is here!

Let’s take a look to what chefs cooked up for our taste pleasure:

3D support: finally adobe put some z in flash!:D on astro release notes Adobe’s claiming that they’re enabling everyone to create complex 3D effects using simple code… mmm… i’m curious about that! i’m a papervisioned guy!
hardware acceleration: flash player 9.0.115 introduced hardware acceleration… astro is becoming even friendlier with your gpu. Now flash player supports GPU compositing and blitting, both parameters must be enabled by html.
Adobe Pixel Bender: formerly Hydra (which was a cooler name ), this system let us create our own custom filters and apply them runtime..
New text engine! Multiple columns text, support for chinese (GB18030 )
Speex! a free codec used to encode speech….Ribbit thanx while pacifica voip project is waiting…
Dynamic sound generation!…Andr√© Michelle’s “Adobe make some noise” petition really made some noise!
File reference runtime access! Finally we don’t have to upload our files to manipulate them inside our RIAs! Files are handled as ByteArrays so we can do quite everything
Many others…

Another impressive innovation is Astro is available for Ubuntu Linux users too…so even penguins can try new features shown in the demo on labs site.

Finally the coolest news: WE ALREADY CAN COMPILE CONTENT TARGETING ASTRO!

I’m so excited i don’t need mana to stay awake tonight!:D

Gradient Masking – La sfumatura nelle maschere

pigiuz — Sun, 06 Jan 2008 00:23:46 +0000

Questo √® uno “microtutorial” piuttosto semplice sulle maschere (sono 2 linee di codice -.-) che per√≤ ho notato non essere troppo conosciuto.

Come creare un effetto “pila” o “occhio di bue”? o pi√π banalmente, come creare una maschera sfumata con flash8 o superiori?

crea un movieclip da mascherare
crea un altro movieclip contenente una forma con riempimento a gradiente nel quale almeno un colore abbia alpha minore di 100
posiziona nello stage (fisicamente o via actionscript) i due clip: il mascherato e la maschera
via actionscript imposta a true la propriet√† “cacheAsBitmap” di ciascun movieclip
sempre via actionscript imposta la maschera del movieclip da mascherare (setMask in AS2 o mask in AS3)

ecco il risultato:
(Please open the article to see the flash file or player.)

Flow – eclipse flash launcher

pigiuz — Tue, 11 Dec 2007 08:55:00 +0000

“Flow” √® un tool che permette di lanciare il compilatore flash (sia il test movie che il compile vero e proprio) direttamente da Eclipse.

Lavora in command line, ma viaggia in automatico, una volta configurato il path di compilazione nel file .config eclipse fa praticamente tutto da sola.

Esistono altri progetti simili a questo, lo stesso Jaco ne cita due : flashCommand e compileProject, ma a quanto pare non sono pi√π sviluppati.

Jaco ha pubblicato anche uno screencast dove viene mostrato Flow in azione (Venetian Spoken ).

Per ora Flow √® disponibile in EXE…quindi niente trippa per gli unixbased come il sottoscritto…per ora (vero jaco?:D)

Un tool che non faciliter√† la vita a tutti, ma a molti

Grande, respect.

Actionscript 3 VS Actionscript 2

pigiuz — Wed, 03 Oct 2007 21:35:03 +0000

AS2 o AS3?
Idee e opinioni degli addetti ai lavori sulle versioni di actionscript, sulle tendenze di mercato..

Riporto il topic su wave9.it, leggetelo qui o andate direttamente alla fonte

Apro questo thread perch√® √® forte lo slancio che da un p√≤ di tempo a questa parte ha trascinato l’attenzione di molti “flasher” su AS3, e diverse sono le opinioni a riguardo tra gli addetti ai lavori e non solo.

Actionscript 3 ha portato insieme gioie e perplessit√†,
ha sicuramente accentuato le differenze tra le figure “flash coder” e “flash designer” marcando pi√π strettamente il territorio di confine.
Forse ha incrinato la figura del “flasher” come “colui che sviluppa in flash” e ha attirato (soprattutto con la sempre maggiore diffusione di flex) una valanga di coders a cimentarsi con actionscript.

C’√® chi pensa che AS3 abbia solo complicato le cose, o meglio turbato l’equilibrio che si era andato a creare con l’avvento di flash mx,
che con AS3 serva scrivere molto pi√π codice per fare le stesse cose che si facevano in AS2, e quindi non serva a nulla,
che AS3 e la AVM2 (la virtual machine di flash player 8.5+) sia solo una strategia di marketing per stravolgere il mercato e vendere flash 9 (ehm…cs3) e flex builder ad una fetta pi√π ampia di coders….

C’√® anche chi pensa che AS3 sia il “futuro” ( anche se non ancora ben rodato),
che AS3 sia effettivamente pi√π valido di AS2, che la virtual machine sia nettamente pi√π performante della precedente…e via cos√¨…

…e intanto hanno presentato al MAX il flash player 10…

E voi cosa ne pensate?

Diffusione Flash Player – Ecco le statistiche ufficiali
