Multitouch Gesture in FlashLite 4 and N8

[sangramp@cybage.com]

Has any-one used Multitouch gestures in FlashLite 4 and Nokia N8?

I test the examples in the Device central and all it works correctly using Multitouch Panel, but when I test the same apps on N8, nothing happens. I am not able to get any of the Muliti-touch gestures working on N8.

Am I missing out on anthing?

Following is the sample code for Zoom gesture:

Multitouch.inputMode = MultitouchInputMode.GESTURE;
square_mc.addEventListener(TransformGestureEvent.GESTURE_ZOOM , onZoom);
function onZoom(e:TransformGestureEvent):void
{
	square_mc.scaleX *= (e.scaleX+e.scaleY)/2;
	square_mc.scaleY *= (e.scaleX+e.scaleY)/2;
}

No one experimenting with FlashLite 4 on N8 still :-(

Hi,

I am not sure what multitouch gesture you are looking for to code, but left-right and up-down swipes did work on the N8 when I had coded on the Flash Lite 3.x. If you want, the code is as follows:

var startX:Number;
var startY:Number;
var endX:Number;
var endY:Number;

var gesturesListener:Object = new Object();

gesturesListener.onMouseDown = function()
{
startX = _root._xmouse;
startY = _root._ymouse;
}
gesturesListener.onMouseUp = function()
{
endX = _root._xmouse;
endY = _root._ymouse;

checkGesture();
}

Mouse.addListener(gesturesListener);
// minimum length of an horizontal gesture
var MIN_H_GESTURE:Number = Stage.width / 3;
// minimum length of a vertical gesture
var MIN_V_GESTURE:Number = Stage.height / 3;

// flags for each kind of gesture
var UP_TO_DOWN:Number = 1;
var DOWN_TO_UP:Number = 2;
var LEFT_TO_RIGHT:Number = 4;
var RIGHT_TO_LEFT:Number = 8;

function checkGesture()
{
var xDelta:Number = endX - startX;
var yDelta:Number = endY - startY;

var gesture:Number = 0;

if(xDelta > MIN_H_GESTURE)
gesture |= LEFT_TO_RIGHT;
else if(xDelta < - MIN_H_GESTURE)
gesture |= RIGHT_TO_LEFT;

if(yDelta > MIN_V_GESTURE)
gesture |= UP_TO_DOWN;
else if(yDelta < - MIN_V_GESTURE)
gesture |= DOWN_TO_UP;

if(gesture > 0)
handleGesture(gesture);
trace(gesture);
}

function handleGesture(gestureFlags:Number)
{
if(gestureFlags & LEFT_TO_RIGHT)
moveLeft();
if(gestureFlags & RIGHT_TO_LEFT)
moveRight();
if(gestureFlags & UP_TO_DOWN)
trace("up to down gesture");
if(gestureFlags & DOWN_TO_UP)
trace("down to up gesture");
}

Thanks Supriya, but this is not what I am talking about.

I know about these gestures, I am talking about the Multi-touch gestures which are supported in FlashLite 4 and N8 devices. You can rotate and zoom the content using two fingures, as supported on iphones.

I tried few days ago for a prototype on N8 for multi-touch gestures. But unfortunately, it didn't worked at all on actual device. I had to switch to Nexus One for the prototype project.

Not tried again so far, but will take a look again soon as the FL4 docs says, it supports multi-touch gestures.

I also tried using TouchEvents in FL4 on my N8 but it seems to be unsupported!

have a look at this thread: http://discussion.forum.nokia.com/fo...amp-TouchEvent

I second that TouchEvents are not yet implemented in FL 4 on Symbian^3. Tested one of my application and do some simple tests but not able to get any positive result. Waiting for TouchEvents support in next update.
