[NEW UPDATE!] Fingers - Touch Gestures - #1 in Quality, Support and Features : Dozens of Gestures✓

That’s the right function. I think you want to add executing stage as well.

 

Hi, I'm using fingers to detect both pan (virtual joystick) and swipe (up and down) to jump and crouch, but while it works in the editor, the swipe does not work at all when building on Android

Code (CSharp):

1.        
2. private void OnEnable()
3.         {
4.             panGesture = new PanGestureRecognizer
5.             {
6.                 PlatformSpecificView = PanPlatformSpecificView,
7.                 ThresholdUnits = PanGestureThresholdUnits
8.             };
9.             panGesture.StateUpdated += Panned;
10.  
11.             swipeGesture = new SwipeGestureRecognizer ();
12.             swipeGesture.PlatformSpecificView = SwipeImage;
13.             swipeGesture.ThresholdSeconds = SwipeThresholdSeconds;
14.             swipeGesture.DirectionThreshold = 0;
15.             swipeGesture.MinimumNumberOfTouchesToTrack = swipeGesture.MaximumNumberOfTouchesToTrack = SwipeTouchCount;
16.             swipeGesture.EndMode = SwipeMode;
17.             swipeGesture.StateUpdated += Swipe_Updated;
18.  
19.  
20.             if (!string.IsNullOrEmpty(CrossPlatformInputHorizontalAxisName) && !string.IsNullOrEmpty(CrossPlatformInputVerticalAxisName))
21.             {
22.                 crossPlatformInputHorizontalAxisObject = FingersCrossPlatformInputReflectionScript.RegisterVirtualAxis(CrossPlatformInputHorizontalAxisName, out crossPlatformInputAxisMoveNewlyRegistered);
23.                 crossPlatformInputVerticalAxisObject = FingersCrossPlatformInputReflectionScript.RegisterVirtualAxis(CrossPlatformInputVerticalAxisName, out crossPlatformInputAxisMoveNewlyRegistered);
24.             }
25.             if (!string.IsNullOrEmpty(CrossPlatformInputJumpAxisName))
26.             {
27.                 crossPlatformInputJumpAxisObject = FingersCrossPlatformInputReflectionScript.RegisterVirtualAxis(CrossPlatformInputJumpAxisName, out crossPlatformInputAxisJumpNewlyRegistered);
28.             }
29.             clearJumpAction = ClearJump;
30.  
31.  
32.             FingersScript.Instance.AddGesture(panGesture);
33.             FingersScript.Instance.AddGesture(swipeGesture);
34.         }

If I comment the "FingersScript.Instance.AddGesture(panGesture);" line, the swipe start working also on Android builds.

My swipe method looks like that:

Code (CSharp):

1.         private void Swipe_Updated(DigitalRubyShared.GestureRecognizer gesture)
2.         {
3.  
4.  
5.             SwipeGestureRecognizer swipe = gesture as SwipeGestureRecognizer;
6.             Debug.LogFormat("Swipe state: {0}", swipe.State);
7.             if (swipe.State == GestureRecognizerState.Ended)
8.             {
9.                 float angle = Mathf.Atan2(-swipe.DistanceY, swipe.DistanceX) * Mathf.Rad2Deg;
10.  
11.                 Debug.LogFormat("Swipe dir: =====> {0}", swipe.EndDirection);
12.  
13.                 if (swipe.EndDirection == SwipeGestureRecognizerDirection.Up)
14.                 {
15.                     SwipeUpCallback.Invoke();
16.                 }
17.                 else if (swipe.EndDirection == SwipeGestureRecognizerDirection.Down)
18.                 {
19.                     SwipeDownCallback.Invoke();
20.                 }
21.             }
22.         }

What I notice from logcat is that "swipe.State" is never equal to GestureRecognizerState.Ended
If I read the logs in the Unity console, the Ended states appears correctly.

Can you help me please?
Thanks in advance!

 

Pan needs to be set to execute simultaneously with swipe.

 

Hello! I am wondering if multi-finger touch can be implemented using this plugin? I'm interested in simultaneous touch. I want to make some unique beautiful swipe using multiple fingers.

 

Of course. This is set up by default.

 

Did you answer this question? "Hello! I am wondering if multi-finger touch can be implemented using this plugin? I'm interested in simultaneous touch. I want to make some unique beautiful swipe using multiple fingers." Show the diagram a picture of how to make a swipe with several fingers

 

Yes, this is on by default. You can specify the max number and min number required fingers per gesture.

Hi! I'm new to this. I imported the asset into a nearly empty Unity 2D project. And then it showed 2 errors. Could there be any setting wrong? I'm using Unity 2020.3.21f1 on Windows 10.

Code (CSharp):

1. Assets\Fingers\Demo\Scripts\DemoScriptPlaceObjects.cs(45,49): error CS0246: The type or namespace name 'GestureRecognizer' could not be found (are you missing a using directive or an assembly reference?)
2. Assets\Fingers\Demo\Scripts\DemoScriptPlaceObjects.cs(22,16): error CS0246: The type or namespace name 'FingersPanOrbitComponentScript' could not be found (are you missing a using directive or an assembly reference?)

 

I'm not seeing this. What fingers version are you running on?

 

I just imported it yesterday and the version seems to be 3.0.3. Currently, I have installed Visual Studio with only Unity target. May this be the cause?

And if I open and try to import, it doesn't show the proper class to be imported. Which GestureRecognizer it is? Windows.UI.Input.GestureRecognizer seems to be UWP which I didn't install.

EDIT:
I deleted the Library folder and reopened the project. Then it works fine. Seems to be a problem after upgrading the project version.

 

Hi, apologies if this has been asked before; I didn't find what I was looking for by searching this thread.

I'm having an issue where in Android builds, the FingerHandlerScript.Touches.Count never resets when my fingers are no longer touching the screen.

It works fine in the editor; it returns 1 when the mouse button is held down, and returns to 0 when the button is released, but on my phone, touching the screen changes Touches.Count from 0 to 1 as expected, but when I remove my finger it remains at 1.
Because of this, my 1-finger Pan gesture only works at the beginning. Once I've touched the screen with two fingers to use my 2-finger Pan gesture, the 1-finger Pan no longer works. Everything works as expected in the Editor.

Strangely enough, switching to another app and back (Without restarting it) resets the Touches.Count back to 0 and I can use my 1-finger Pan again until I touch with two fingers.

It's possible I've set the gestures up incorrectly? I based it on DemoScript.cs.

I'm using 2019.4 and the new Input System. (I followed the instructions for it in the readme)

Thanks in advance!

 

Probably the first thing to try is does the old input system work?

 

Are you still dealing with this error?

 

Yes, I ran out of time and ended up having to change everything back to the old input system to make it work. Changing to the old input system made it work as expected with no additional tweaking of anything related to Fingers.

 

I had to click on the event system in the scene and click a button to enable new input system functionality. Once I did that, the new input system started working as expected, I got taps and double taps in the tapdoubletap demo scene. I will add a note for this in the readme.

 

Fingers Gestures 3.0.4 is now live on the asset store with fixes for touches when using the new input system.

 

Hey guys! I'm having a weird issue with SwipeGestureRecognizer. The level is lazy-loaded from several scenes dynamically. And after the first UnloadSceneAsync of any loaded scene, SwipeGestureRecognizer just stops working. Resetting or creating a new instance of it doesn't help.

The unloaded scene contains a level itself - just a bunch of line renderers. Everything else is not destroyed.

The game object with a script that initializes SwipeGestureRecognizer is set to not be destroyed on load.
EventSystem and FingersScriptPrefab game objects are also set to not be destroyed, so scene unloading doesn't affect them.

The only workaround to fix the issue I found so far is to destroy and re-instantiate a game object with a script that initializes SwipeGestureRecognizer. Do you guys have any ideas why is that happening?

 

Just found a similar issue in a discord - FingersScript.GestureLevelUnloadOption.Nothing; - this is what I needed

 

Hi, I have a question about fingers zoom pan, and tap gesture working with a ui panel.
I want to create a full screen ui panel, and hope zoom pan and tap gesture will not be triggered when this ui panel shown.
I enabled and disable zoom pan and tap gesture script when open and close ui panel.
May I know whether there is a easy to implement the same function?

Thank you very much

 

The CaptureGestureHandler func on the FingersScript.Instance is perfect for this. Set it to your C# function and if the game object parameter of the function is your panel, then return true to eat the gesture.

 

I can't seem to get double taps to work...

My code is fairly straightforward:

Code (CSharp):

1. void Start()
2.     {
3.         tapGesture = new TapGestureRecognizer();
4.         tapGesture.StateUpdated += TapGestureCallback;
5.         tapGesture.RequireGestureRecognizerToFail = doubleTapGesture;
6.         FingersScript.Instance.AddGesture(tapGesture);
7.         doubleTapGesture = new TapGestureRecognizer();
8.         doubleTapGesture.NumberOfTapsRequired = 2;
9.         doubleTapGesture.StateUpdated += DoubleTapGestureCallback;
10.         FingersScript.Instance.AddGesture(doubleTapGesture);
11.         swipeGesture = new SwipeGestureRecognizer();
12.         swipeGesture.Direction = SwipeGestureRecognizerDirection.Down;
13.         swipeGesture.DirectionThreshold = 1.0f;
14.         swipeGesture.StateUpdated += SwipeGestureCallback;
15.         FingersScript.Instance.AddGesture(swipeGesture);
16.     }

Followed by

Code (CSharp):

1. private void TapGestureCallback(DigitalRubyShared.GestureRecognizer gesture)
2.     {
3.         if (gesture.State == GestureRecognizerState.Ended)
4.         {
5.             Debug.Log("Single tap");
6.         }
7.     }
8.  
9.     private void DoubleTapGestureCallback(DigitalRubyShared.GestureRecognizer gesture)
10.     {
11.         if (gesture.State == GestureRecognizerState.Ended)
12.         {
13.             Debug.Log("DOUBLE tap");
14.         }
15.     }
16.  
17.     private void SwipeGestureCallback(DigitalRubyShared.GestureRecognizer gesture)
18.     {
19.         if (gesture.State == GestureRecognizerState.Ended)
20.         {
21.             Debug.Log("Swipe");
22.         }
23.     }

It is able to detect single taps and swipes according to the console (and the fact that I can click on UI buttons). But double taps don't seem to be giving me any logs...

 

Does demo scene tap and double tap work? If so you may just need to set your gestures to execute simultaneously.

 

The demo does work. Sorry for the obvious question but... how do I set gestures to execute simultaneously?

 

Call

gesture.AllowSimultaneousExecution(otherGesture)

 

Yes

doubleTapGesture.AllowSimultaneousExecution(tapGesture);

does make it work, but comes with the issue that now whenever I double tap it also registers two regular taps on top.

 

I found the issue, a rather foolish one on my side too. The

RequireGestureRecognizerToFail

is unable to do anything because

doubleTapGesture

does not yet exist. In my original script the single tap is created before the double-tap.

Though I am surprised that this did not return an error on the console. Nevertheless, thank you for the speedy replies!

 

Set the double tap gesture to require the tap gesture to fail.

 

Hey guys. I faced a lot of memory allocations using Fingers scripts due to excessive foreach usage on IEnumerable/ICollection variables.

I'm using the latest unity, latest Fingers asset (3.0.4) and IL2CPP build.





Profiling on device shows a lot of allocation in foreach methods due to Enumerator retrieval:


There are a lot of usages of foreach in the code, so it makes such allocations basically in every frame!
As far as I know, Unity fixed this issue, so foreach shouldn't allocate, but my testing shows that it's not true.

Am I missing something, or that's the real problem, and every foreach loop just must be replaced with the for loop?

 

Sounds like a regression for unity. I’d file a bug…

 

Hi jjxtra.
Fingers are a great product. It is an essential part of my product.

Me too, FingersScript keeps generating some GC Alloc every frame.
It always happens even if the user does not touch the screen, so the accumulation reaches 100KB/sec. I'm requesting that this be removed. It is acceptable because it is necessary to be Alloc to notify the touch information. However, it is a pity that it kept leaking when I was not touching it.

Unity handles foerach properly for List<T> and Dictionary<T>, but not for other collections. (It hasn't changed since a few years ago)
See that the profiler is only happening to the ReadOnlyCollection.
Also, Sort () causes a slight GC Alloc. I think Fingers should handle this.

Fingers ver 3.0.4
Unity 2020.3.28 (windows10)
new input system package 1.30
run profile on android 11.

I can look into this. If it is not impacting your frame rates or causing app crash then I would consider it non-critical.

 

Hi.My UI camera's render mode is ScreenSpaceCamera.How do I use FingersJoystickScript?

 

I’d have to make some adjustment to that script as it assumes screen space overlay.

 

I would like to do camera pan (my camera always see on one target / the gameobject) then I want to be able to rotate the gameobject based on the camera pan (on gameobject axis: X, Y, and Z), how is it possible?

Thanks

 

A pan gesture will make it easy to pan the camera. For rotating the game object, simply read the deltax/deltay properties of the pan gesture and apply some rotation to the game object on your desired axis.

 

Thank for response.

This is the detail I would like to achieve

What I want to achieve is ability to rotate a game object in all axis (x, y, z) regarding the camera position / rotation.

The camera will always focus on the game object and rotate around the game object.

So whenever the camera rotate on specific angle I would like to detect that any drag / swipe gesture (x swipe, or y swipe) on screen will rotate the game object on the specific axis (x, y, z) that Perpendicular to the swipe / drag gesture.

Please advice Thanks

 

Hello I had a question about ImageRecognition and its accuracy
I've set the
ImageGestureImage - imageRows field value to 40 (I think it effects the accuracy right?)
and score padding = 0.01 and similarity minimum to 1
still my shape doesnt get recognized correctly
im trying on "infinity" shape
the shape below is still considered infinity
same thing sometimes happen between a circle and a rectangle
how can I improve this?

 

Hey guys, I have a scene where I want the Image object to Zoom out, as the touch event ends (Pinch to zoom). I am referring to ZoomableScrollView Demo scene here, but cant exactly figure out how to make it so that when the touch event ends, the image should zoomout to its original size and anchor. Can Anyone help with with this? Thanks

 

can i integrate this asset with Visual Scripting (the old Bolt) ? And if yes how? Please explain like I'm 5 years old if you have time.

Thanks

 

You can try using the component gesture objects, I think Bolt should be able to reference these...

 

Apologies for not responding the last few months on this forum. Several things have made life very difficult:
- Nasty cold in March
- Influenza in April
- Covid in May
- Unity bug that has existed for years stops emailing forums post notifications

I am trying to get my health back and it's slow going, I will try to remember to re-enable the email notifications for the forum more often...

 

try a mix of getting sun every day with a normal walk to move the muscle at least one hour. then buy from your pharmacy one of those mix of vitamins. more there are inside better it is. then buy the one that have D3 vitamin. Not all of them have it. you need that to not be a small dose.

this should help you up.

if you are not ok at the moment, get an antibiotic.

consult your doctor first off course

 

Thank you I will try upping the vitamins and get some sun

 

Hi,here
Great job for mobile input! And I got a question that how to cosume tap event(driven by fingers gestures like tapGesture) when tapping on a existing UI button(Or a Image which got a component that implements “IPointerUpHandler”),In my case screen UI button would be more priority than screen touches(somewhat blank area). So how to implement that?

 

Buttons will block the gesture by default. You can add typeof(Image) to the ComponentTypesToDenyPassThrough property on FingersScript to block images.

 

In my case， It looks failed to block gestures on a "Button" . The touches show still visible when touching on a Button.. Shoud I config somewhere for blocking?

 

I wonder if its possible to change the finger, which is tracked by a pan-gesture, without lifting all fingers.

What i mean is the following:

1. You put finger_1 on the screen, an the pan-gesture-callback reacts on it (for example it's moving something).
2. Now you put another finger, finger_2, on the screen. Now two fingers are on the screen. The pan-gesture-callback should not react anymore. (Instead maybe another gesture, like scale, should react here)
3. Now you are lifting finger_1. Only finger_2 is now on the screen, and the pan-gesture-callback is reacting again.

The reason for this whole thing, is just to make a smooth transition between gestures, whithout lifting all the fingers.
I tried to get it to work, but to no avail. It is possible?

 

@jjxtra Do you have any examples for multiple selecting objects like in a word game. e.g. a 5 x 5 matrix and selecting all the boxes you swipe over.

 

First of all, great job about Fingers ! It's a fantastic gesture package !

We try to do a Gizmo rotation with one touch gesture (pan gesture) but we have some trouble.

This is what we actually try (work in progress) :

Code (CSharp):

1. enum RotationMode { X, Y }
2.  
3. void PanGestureGestureUpdated (GestureRecognizer panGesture) {
4.     if (panGesture.State == GestureRecognizerState.Executing) {
5.         Vector2 screenDirection = new Vector2 (turnSpeed * panGesture.DeltaX, turnSpeed * panGesture.DeltaY);
6.         Vector2 worldScreenDirection = Camera.main.transform.TransformDirection (screenDirection);
7.         Vector3 projectedDirection = Vector3.ProjectOnPlane (worldScreenDirection, rotationMode == RotationMode.X ? transform.right : transform.up);
8.         transform.Rotate (rotationMode == RotationMode.X ? Vector3.right : Vector3.up, rotationMode == RotationMode.X ? -projectedDirection.y : projectedDirection.x, Space.Self);
9.     }
10. }

Can anyone help us to have a working pan gesture to turn an object around self axis ?

This is what we want to do : https://threejs.org/examples/?q=control#misc_controls_transform
Toggle rotation mode (press E) and local mode (press Q).
