Dynamically changing tracking orientation through Unity C#

[Mungo]

Hi,

I'm working on a project where hands are tracked from both sides of the device (only one side at a time). I'm having trouble with accessing the config settings to reverse the orientation from a C# script.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Leap.Unity;
using Leap;

public class LeapConfigTester : MonoBehaviour {

    public LeapServiceProvider leapProvider;
    public Controller leapController;
    public Config leapConfig;

    void Start()
    {
        leapController = leapProvider.GetLeapController();
        leapConfig = leapController.Config;
    }
	
	void Update () {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            bool isFlipped = leapConfig.GetBool("image_processing_flipped");
            Debug.Log("Currently flipped: " + isFlipped);

            bool setSuccess = leapConfig.SetBool("image_processing_flipped", !isFlipped);
            Debug.Log("Set success: " + setSuccess);

            bool saveSuccess = leapConfig.Save();
            Debug.Log("Save success: " + saveSuccess);

            bool connectedController = leapController.IsConnected;
            Debug.Log("Controller connected: " + connectedController);
        }
    }
}

This prints to the console:

Currently flipped: True
Set success: True
Save success: False
Controller connected: True

I'm essentially trying to make the spacebar function like the "Reverse Orientation" button in the Leap Control Panel.
Any idea why the save method is failing?

Thanks,
Mungo

Might help...Version 3 changed a few things in config...

Let us know if you get it to work!

Thanks for the suggestions! I've changed the test program, however the Config.Set<> is still failing. Here is my updated code, I've removed the unnecessary parts:

void Update () {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            bool isFlipped = leapConfig.Get<bool>("image_processing_flipped", delegate (bool currentSetting)
            {
                Debug.Log("current setting: " + currentSetting);
            });

            bool setSuccess = leapConfig.Set<bool>("image_processing_flipped", !isFlipped, delegate (bool success)
            {
                if (success)
                {
                    Debug.Log("SET success");
                }
                else
                {
                    Debug.Log("SET failed");
                }
            });
        }
    }

Output in Unity Console:

current setting: [True/False]
SET failed

Note: the current setting changes when I click the "Reverse Orientation" button in the Leap Control Panel, so the Config.Get<> seems to be working fine.

That is beginning to look overcomplicated.

If you are calling the Interaction Manager isn't there a dynamic setting in Orion 4 and interaction that sets the direction and stops the flipping to begin with?

[Mungo]

I couldn't find anything in the documentation that has anything to do with tracking orientation in the interaction manager. I'll try explaining my problem in case that helps.

I'm making a game where people stand on opposite sides of a table, leap motion suspended above the table facing down. After player 1 finishes their turn, I want them to press a virtual button and have the tracking flip so that the leap motion tracks the other player's hands instead. I can't find a way to set the orientation of the tracking through Unity without going to the control panel and pressing "Reverse Orientation".

Thank you for your help, it is much appreciated.

Ok so you do not have to do anything to have LEAP track hands from any direction.

Reverse orientation is used to change the settings from desk upward point of view to visor downward point of view.

The visor view takes into consideration the movement of the camera with the head and that the back of the hands orientation should be considered before the palm sides to identify left and right hands.

The desk-up view presumes a fixed position camera and the palm sides are expected.

This is for processing efficiency. If your hands are not as expected it will adjust to them.

Regarding the design of your system, the virtual button is actually switching from Player 1 is active to Player 2 is active and you should simply program accordingly.

You could experiment with the axis orientations for Player 1 and Player 2 if there are still issues.

You could try starting the game with all 4 hands in camera range and only allowing one player to act at a time. No button would be required

If you can't get interaction engine to handle multiplayer well, then I would suggest multi-camera solutions.

To increase efficiency, you might try to use the camera from the desk side.

Thanks for your help! After some testing, I figured that the auto-orient tracking suits my needs while in VR-mode.

Sometimes the tech just works
