Question on PalmNormal.Roll

[hongkai0818]

Hi, previously in our code we have been using the following codes.
float pitch = hand.Direction.Pitch;
float yaw = hand.Direction.Yaw;
float roll = hand.PalmNormal.Roll;

However, in the latest version 6.0.0, these are no longer valid. May I know how we can obtain the roll angle of hand.PalmNormal? If we need to calculate manually, how can we obtain the coordinate of the leap motion? (X-Z plane)

Hi, thanks for the question and thanks for trying out 6.0.0

You can see how we calculated these by grabbing the code from Vector in the Legacy Package

Here is a static utility class that will produce the same results from unity's Vector3:

using UnityEngine;

public static class Vector3Utils
{
    public static float GetRoll(this Vector3 v)
    {
        return (float)System.Math.Atan2(v.x, -v.y);
    }

    public static float GetPitch(this Vector3 v)
    {
        return (float)System.Math.Atan2(v.y, -v.z);
    }

    public static float GetYaw(this Vector3 v)
    {
        return (float)System.Math.Atan2(v.x, -v.z);
    }
}

Thank you so much for your prompt response
