Moving from Flash to Unity has been a fantastic experience, and the one thing that sticks out the most is that it’s so much fun! There’s also a huge wealth of Unity resources on the web, and the community is incredibly helpful. With the choice between JavaScript, C#, and Boo, it’s not difficult to move from making Flash content in ActionScript 3 to producing exciting projects in Unity. Did I mention there’s a free version of Unity? Go and get it. Now!

Unity has to be the hottest technology out there. With version 3 – out in summer – you’ll be able to export for PC, Mac, web, iPhone, iPad, Android, PS3, Wii, 360.. it’s stunning, and it’s a far cry from anything that could be produced in Papervision / Away3D.

This is absolutely awesome news – ActionScript programmers can create apps for the iPhone. There’s more information here.

A few questions spring to mind:

• What will performance be like?
• Can we take advantage of all the hardware, such as accelerometers, GPS, etc?
• When can I get my hands on it!?

For a while I’d been saying this was the most logical thing for Adobe to do, but I never thought they’d actually do it..

Yey!

[UPDATE]

Funnily enough, all my questions are answered in the Developer FAQ!

Performance:

The iPhone and iPod touch have processors significantly slower than those found on most desktop PCs and Macs. Thus, content may run slower than it does when running on a desktop personal computer. However, the exact differences will depend on the specific content.

In addition, the hardware specifications vary greatly between different versions of the iPhone and iPod touch. Because of this, it is important that you test your content early and often across all devices which you plan to target.

The hardware that’s supported:

• MultiTouch
• Screen Orientation
• Saving images to Photo Library
• Accelerometer
• Geo-location
• Cut / Copy / Paste

Additionally, we can take advantage of OpenGL ES. This could be extremely important for games!

In order to make development of high-performance applications easier, applications built for the iPhone also can take advantage of an augmented rendering pipeline that uses OpenGL ES. This augmented rendering pipeline enhances the Flash rendering model to allow developers to take advantage of the GPU on iPhones. By enabling this rendering path, you have the ability to modify your display objects to put them on a hardware surface

Flash suddenly got a lot more exciting.

I prefer to write pure AS3 inFlashDevelop, using the Flex SDK to compile. I’ve used MinimalComps on occasion, and I’ve been happy with the results. However when it comes to laying out anything particularly complex, I’ve had to fall back to Flex or CS3.

The release of MinimalDesigner should make using MinimalComps even easier now. Thanks Keith!

var red:Sprite = new Sprite();
red.graphics.beginFill(0xFF0000);
red.graphics.lineTo(40, 0);
red.graphics.lineTo(40, 150);
red.graphics.lineTo(0,150);
red.graphics.lineTo(0,0);

red.x = 40;
red.y = 40;

addChild(red);

var green:Sprite = new Sprite();

green.graphics.beginFill(0x00FF00);
green.graphics.lineTo(40, 0);
green.graphics.lineTo(40, 150);
green.graphics.lineTo(0,150);
green.graphics.lineTo(0,0);

green.x = 300;

var useRotation:Number=10;

var redBmpData = new BitmapData(red.width, red.height, true, 0);
redBmpData.draw(red);

var useDimension:int = Math.ceil(Math.sqrt((green.width * green.width) + (green.height * green.height)));
var diffWidth:int = useDimension - green.width;
var diffHeight:int = useDimension - green.height;
var newBD:BitmapData = new BitmapData(useDimension,useDimension,true,0);
var angle_in_radians:Number = Math.PI * 2 * (useRotation / 360);
var m:Matrix = new Matrix();
m.translate((green.width / 2) * -1, (green.height / 2) * -1);
m.rotate(angle_in_radians);
m.translate(green.width / 2, green.height / 2);
m.translate(diffWidth / 2, diffHeight / 2);
var translatedPoint:Point = m.transformPoint(new Point(0,0));

trace(useDimension);
var greenBmpData = new BitmapData(useDimension,useDimension,true,0);
greenBmpData.draw(green,m);

/*var sampleGreen:Bitmap =new Bitmap(greenBmpData);
addChild(sampleGreen);
sampleGreen.x=200;
sampleGreen.y=200;
*/
green.rotation=useRotation;

stage.addEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);

function onMouseMove(e:MouseEvent):void {
	green.x = mouseX;
	green.y = mouseY;

	if (redBmpData.hitTest(new Point(red.x, red.y),
	255,
	greenBmpData,
	new Point(green.x-translatedPoint.x, green.y-translatedPoint.y),
	255

	  )) {
		trace("hit");
		red.filters = [new GlowFilter()];
	} else {
		red.filters = [];
	}
}

I’ll blog a better example of this, with comments and an explanation of what it’s doing in the next few days.

VizualPV3D

A GUI for Papervision! It looks rather similar to Lightwave, although orders of magnitude less powerful. I’ll be interested to see how this evolves. Could come in handy one day!

Swf Class Explorer

This was a useful utility on a recent project, as there’s no “ApplicationDomain.getAllDefinitions():Array”. Worth bookmarking.

Violet UML Editor

Jon from Unwrong showed me this rather nifty UML editor. Great for drawing quick, simple diagrams. Cross-platform, and free.

Talon: Firefox Plugin

A great plugin for Firefox, which allows you to right-click and capture a page (or region). From there you can upload/share/edit on Aviary, copy to clipboard, or save to desktop.

Simply stunning.

It’s based on work by Mehmet Akten, which in turn is based on this paper: Real-Time Fluid Dynamics for Games.

It just doesn’t stop. The multiple-award-winning Bow Street Runner we made for Channel 4 is up for another award, this time it’s the Broadcast Digital Awards. We’re in the Best Use of Digital Technology category.

The nominees are:

• BBC iPlayer
• Bow Street Runner, Channel4.com
• Current
• Freesat
• Mycbbc
• Obama: The Inauguration, Sky News

Wow. That’s quite some company to have!

Creating the Shopper 13 game sparked my enthusiasm, and I’ve been gathering new parts to experiment with:

In addition to that, I’ve also got a Wii Nunchuck hooked up to my Arduino which I’m currently controlling Flash and Servos via the accelerometer and analog joystick. Oh, and a Laser.. and some Papervision too. When I’ve got something interesting, I’ll post it. Hopefully that’ll be in the next few days

Well I have to start building my robot army somewhere..

Here’s a photo I took a while back:

It was a brilliant project to work on, and one of the most fun things I’ve done for a while. Everyone involved was fantastic, and the exhibition itself looks superb. The game is now installed on a row of consoles and is open to the public. The controls are made from arcade-quality components, and uses a Mini-Pac to talk to the PC via USB.

Here’s a very brief clip of it on BBC News 24 (00:30):

If you’re in the area, do go and check out the exhibition, it’s great!
