Hi!

I'm the author of FingerGestures, a Unity plugin that allows you to detect common input gestures. Due to popular request, I’ve recently been working with Alex on adding support for FingerGestures to PlayMaker, and now have something ready for testing!

I've attached to this post a package with the early beta version of the new FingerGesture actions. At the moment there's only two of them:
- FingerGestureDetectInput allows you to detect all the default gestures supported by FingerGestures (finger down, finger up, tap, double tap, swipe, long press, pinch, rotation...) and generate an FSM event along with output variables you can store some of the gesture data in
- FingerGesturesGetFingerInfo lets you access all the properties of a specific finger (position, delta position, touch status, touch start time, etc)

It also comes with built-in support for interacting with scene objects via gestures, which should make it quite easy to work with. For instance, you can have the tap gesture event fire only if a specific object was tapped.

I would really appreciate if some of you with access to FingerGestures could give this a try and give me some feedback here.

Thanks in advance!

UPDATE: v0.3
- Made the FingerGesturesDetectionInput stateless when it comes to handling continuous gestures such as drag, pinch and rotation.
- Added "Must Hit Object" property to the FingerGesturesDetectionInput action to require a valid object to be present under the finger(s) for events to fire
- Added support for dragging objects via the FingerGestureDragObject action. See "Playmaker Drag" sample scene in the Samples folder.
- Added "Playmaker Tap" sample in the Samples folder

UPDATE: v0.2
- Added Ignore Layer property to FingerGesturesDetectInput action to ignore colliders in specific layers when raycast for objects under the finger
- Removed left-over raycast in FingerGesturesActionHelpers.PickObject()

one thing I'm trying to achieve is a pinball flipper action in playmaker, I'm hoping this will help me do it.

For this I divide the screen in two halves left and right.
Then I need to detect if finger is pressed left or right screen.
now activate the according left or right flipper. ( rotate physics object )

The difficult part is that the flipper needs to stay up when a finger is pressed down and only release once the finger is up again.  ( rotate back )

If you can make an example with this kind of behavior that would be very insightful on how this works.

Thanks

Got at fair number of errors when I imported the package.

Any idea what I did wrong?

Yeah, you actually need the FingerGestures package too

Huh.  That's curious, because I do have finger gestures and it's installed.  Perhaps I need to use a beta?  Or maybe my installation is mucked up?  What version of playmaker and finger gestures did you test with?

Yup,that was it.  I was using 2.3 not 2.3b.   

Note, that I do get a warning about the variable 'ray' being assigned but never used.

Thanks for the feedback pneil!
Adding an option for the object raycast layer should be no problem, good idea! I will add this asap.

As for the double tap vs single tap issue, it's a bit tricky because there is no perfect way to do this from the code without having bad side effects. The reason for this is explained in more detail in this forum thread.

However, you should be getting BOTH events fired, not just one. In theory, if you do a double tap gesture and have registered for both tap & double tap events,  you should be getting a "tap" event each time the finger tapped the screen, and then a final "double tap" event after two taps occurred. The gestures do not "consume" the input, so they can't prevent one another from receiving input data. Can you double check and confirm you are not getting both events fired please? If not, I might have a bug on my hands

Update: version 0.2
- Added Ignore Layer property to FingerGesturesDetectInput action to ignore colliders in specific layers when raycast for objects under the finger
- Removed left-over raycast in FingerGesturesActionHelpers.PickObject()

This is great! Finger gestures is awesome.

Now, THAT is what I like to hear
