I’m having an issue with this. After adding the Gesture additions onto my initial constructor, after adding the “DragRotateScaleMe” class, the Zoom and Rotation functions throw nothing. I get no errors. It’s just not doing anything. The TOUCH_DOWN function does work though.

Yes this is an expected behaviour because the drag gesture is started by a touch_down and cancelled if there are more than one finger on one object. So if you drag something and then start to scale or rotate it the draggesture will be killed and has to be restarted by retouching it.

You can have a look at the OneFingerMoveGesture class which defines the steps for the DragGesture and modify it to your liking.

I’m having an issue with drag and zoom. It happens also with your DragRotateScaleMe example included in the 0.8 version.

I touch the object with one finger and it moves. Then I add another finger and I can zoom an rotate. But if I want to drag the object again, I have to remove both fingers and touch it again with one finger. If I just remove one of the finger the object won’t move.

Is that normal?
Can it be solved?

Cheers!

After posting the comments I figured it out…

Thanks again for the work you are doing.

The TwoFingerMoveGesture is a base class for all TwoFinger gestures like Zoom and Rotate so it doesn’t dispatch any events but you can change that by adding a dispatch in the dispatchGestureEvent function

There is no swipe gesture at the moment but you could easily implement one yourself.

BTW Is there a way to detect a swipe event?

I’m using this:
GestureManager.addGesture(new TwoFingerMoveGesture(TwoFingerMoveGesture.TRIGGER_MODE_MOVE));

What event do I have to listen to?

I’m trying with this.addEventListener(TransformGestureEvent.GESTURE_PAN, handleDrag);

But it never moves…

What tracker are you using? Do you know if this tracker sends the tracked blobs as cursors or blobs? For the hole GestureManager to work you currently need cursors but it can be easily adapted.

I’ve tried some simple image dragging. Works fine with simulator but can’t make it work with Kinect (which works with examples so TUIO Kinect and udp flash bridge is ok). Do You have any idea what is wrong?
