AIR 16 - GesTouch completely broken [URGEN HELP]

[Applauz78]

Has anyone else noticed that the GesTouch library is broken in AIR 16?

Touch seems to be completely unresponsive. Works fine in AIR 15.

I need to update my app for the 64 Bit support and Gestouch is broken

[Colin Holgate]

AIR 16 defaults to uselegacyaot = no. Not even sure if it can use the old compiler. See this discussion, maybe there's something in there that could help:

Doesn't work with '-useLegacyAOT no' · Issue #75 · fljot/Gestouch · GitHub

I noticed someone said..  but I only have a GesTouch.swc   ..  how can I make these changes ?

My solution:
in org.gestouch.core.GestureState i changed:
"public static const POSSIBLE:GestureState = new GestureState("POSSIBLE");
public static const RECOGNIZED:GestureState = new GestureState("RECOGNIZED", true);
public static const BEGAN:GestureState = new GestureState("BEGAN");
public static const CHANGED:GestureState = new GestureState("CHANGED");
public static const ENDED:GestureState = new GestureState("ENDED", true);
public static const CANCELLED:GestureState = new GestureState("CANCELLED", true);
public static const FAILED:GestureState = new GestureState("FAILED", true);"

to:
"private static var cls:Class = GestureState;
public static const POSSIBLE:GestureState = new cls("POSSIBLE") as GestureState;
public static const RECOGNIZED:GestureState = new cls("RECOGNIZED", true) as GestureState;
public static const BEGAN:GestureState = new cls("BEGAN") as GestureState;
public static const CHANGED:GestureState = new cls("CHANGED") as GestureState;
public static const ENDED:GestureState = new cls("ENDED", true) as GestureState;
public static const CANCELLED:GestureState = new cls("CANCELLED", true) as GestureState;
public static const FAILED:GestureState = new cls("FAILED", true) as GestureState;"

A swc is just  zip file, you could uncompress it and then decompile the swf. But that then just gives you the source code that is on github anyway. And in there I can't find the lines that they are referring to. Perhaps they are lines that the poster created himself? If that's the case, the implication is that anywhere in your code where you say:

var whatever:GestureState = new GestureState("something");

you would change to:

var myclass:Class = GestureState;

var whatever:GestureState = new myclass("whatever") as GestureState;

I think the idea is to fool the compiler into giving you a the GestureState by pretending for a moment to be a generic Class.

I don't have anything like that in my code

I have this...

  function createGestouch():void{

  trace("New GesTouch Created");

  transformGesture = new TransformGesture(mcHolder.mcImg);

  matrix = mcHolder.mcImg.transform.matrix;

  transformGesture.addEventListener(org.gestouch.events.GestureEvent.GESTURE_BEGAN, onGesture);

  transformGesture.addEventListener(org.gestouch.events.GestureEvent.GESTURE_CHANGED, onGesture);

}

and this...

  var imgInitialX:Number = 0;

  var imgInitialY:Number = 0;

  var imgInitialscaleX:Number = 0;

  var imgInitialcaleY:Number = 0;

  var imgInitialRotation:Number = 0;

  var transformGesture:TransformGesture;

  var matrix:Matrix;

  function onGesture(event: org.gestouch.events.GestureEvent): void {

  const gesture:TransformGesture = event.target as TransformGesture;

  matrix = mcHolder.mcImg.transform.matrix;

  // Panning

  matrix.translate(gesture.offsetX, gesture.offsetY);

  mcHolder.mcImg.transform.matrix = matrix;

  if (gesture.scale != 1 || gesture.rotation != 0)

  {

  // Scale and rotation.

  var transformPoint:Point = matrix.transformPoint(mcHolder.mcImg.globalToLocal(gesture.location));

  matrix.translate(-transformPoint.x, -transformPoint.y);

  matrix.rotate(gesture.rotation);

  matrix.scale(gesture.scale, gesture.scale);

  matrix.translate(transformPoint.x, transformPoint.y);

  mcHolder.mcImg.transform.matrix = matrix;

////trace("Rotation = " + gesture.rotation);

  }

  }

Should have read his post more closely, he does say which class he change (org.gestouch.core.GestureState). That's where those lines exist.

When you're using a library that you have as a swc, I think you have the option of including the source AS files instead. You could remove the swc and put the org/gestouch files into your com folder, then make the changes to the lines in org.gestouch.GestureState.as.

[Applauz78]

I made those same changes already to the .as file.  It didnt fix the problem.

[Colin Holgate]

Did you remove the swc?

[Applauz78]

yup..  removed and deleted completely.

[Applauz78]

I made some errors in the AS of the GestureState.as file as well to ensure that it's reading that file.

[Colin Holgate]

Could be worth joining in the github discussion, or raise a new issue about it failing with AIR 16.

[Colin Holgate]

By the way, does it also fail on Android?

[Applauz78]

Not sure .. this is an iOS only app

[Applauz78]

Grrr.. This is terrible.  I was more concerned with the 4 Milkman Games ANE's that I updated and an Instagram ANE ..    Everything else worked seamlessly with AIR 16 ..  Looks like I'm stuck.  Boo.

[Colin Holgate]

You have until June to be 64 bit for updates.

[Applauz78]

Ya .. I also have a new app that needs to be submitted though that uses GesTouch

Hi Applauz78,

Thanks to bring this to our notice. However I could not reproduce the issue on AIR16. I made 2 sample apps, one using text object, and another with an image, on the basis of code provided above. (Dropbox link of the flash builder project is attached).

Dropbox - Gestouch.zip

Kindly give more information and try to run the same on your setup. It will be great if you provide a sample app for the same, with which you are able to reproduce the issue.

Thanks
