Unity Getting position of finger

[TermiGht]

Hello!

I have got my leap motion today and started testing it.
I would like to know that how can I get the position of my finger in vector3, because I checked the api, but things like these:

"Leap.Vector position = finger.TipPosition;
Vector3 unityPosition = position.ToUnityScaled(false);
Vector3 worldPosition = handController.transform.TransformPoint(unityPosition);"

were cannot be found in Unity(for example ToUnity(), or ToUnityScaled() were missing).
I tought these are deprecated functions, so how can i get positions now in Unity vector3, or I did not properly did something in Unity?

Those three lines can all be replaced with:

Vector3 worldPosition = finger.TipPosition.ToVector3();

The ServiceProvider now automatically converts coordinates into the Unity coordinate system and into the world relative to the LeapHandController's transform. The API still uses Leap.Vector objects, so the only additional step is to convert the Vector to a Unity Vector3 object.

Thank you for your quick feedback!
But i haven't got this too.
Just these things:

[Joe_Ward]

Include Leap.Unity in your script. The ToVector3() function is a C# extension which is defined in our Unity namespace, not the base, Leap, namespace.

Okay it is clear now, and it works, thank you!
I would like to ask one last question, as I saw gestures were deprecated too, how can i get gestures now?

[Joe_Ward]

You can't; gestures have already been removed from the Orion C# API used in Unity.

For simple poses, like a thumbs up, or other such gestures that have no motion component, you should be able to construct them with Detectors. For more complicated gestures, you will have to find your own solution. Our recommendation, however, is to focus on natural, physical interactions rather than stylized gestures. For example, actually push a 3D button, rather than make a pushing gesture in the air.

I'm just curious; why is that?

Being able to do gestures is an amazing feature as we can do swipes to open menus, do certain "spells" etc. An example could be what I am currently trying to accomplish: You point your finger, swipe it upwards and say "book", then a book with usable spells will appear in front of you.

I've sort of found my own way to do gestures, but it's really clumsy and not usable in a commercial environment. With built-in support, this would make our life a thousand times easier. I see your point of using physical objects to detect stuff, but it is really only usable for certain features and games.

[AlexColgan]

Even the swipe and tap gestures that we built internally never worked very well from the user point of view, because these are legacy interactions from touchscreens. Combined with a lack of dynamic visual feedback and tutorials, users were often left in the dark, triggering lots of failed interactions and false positives. The types of gestures (really hand poses) allowed by the Detectors Module is closer to what users can be expected to remember and reproduce.

Hi every one i was working on something same like this but what i need to do is get position of the index finger and set that position equal to some other object's/asset's position in the scene.I get the position with the code that you have mentioned here but the position values are different which appear in the inspector and in console when i debug these values and so is the position of the object is not the same as of my hands in the game environment.

What i want is to place that scissor in this game environment on my index finger moves away due to the different position values.

please guide me where i am wrong i am new to leap-motion and unity.
Thanks
