[Getting VerboseData at the fastest rate possible.]

@wdrake @fayre If anyone is experiencing crashes with Unity and threads feel free to use the callback method in the SDK. The thread crashes may be due to aborting a thread during an eye data update. The callback method has been reliable in my testing.

 

using UnityEngine;
using ViveSR.anipal.Eye;
using System.Runtime.InteropServices;

public class CallbackExample : MonoBehaviour
{

    private EyeData eyeData = new EyeData();
    private bool eye_callback_registered = false;

    private void Update()
    {
        if (SRanipal_Eye_Framework.Status != SRanipal_Eye_Framework.FrameworkStatus.WORKING) return;

        if (SRanipal_Eye_Framework.Instance.EnableEyeDataCallback == true && eye_callback_registered == false)
        {
            SRanipal_Eye.WrapperRegisterEyeDataCallback(Marshal.GetFunctionPointerForDelegate((SRanipal_Eye.CallbackBasic)EyeCallback));
            eye_callback_registered = true;
        }
        else if (SRanipal_Eye_Framework.Instance.EnableEyeDataCallback == false && eye_callback_registered == true)
        {
            SRanipal_Eye.WrapperUnRegisterEyeDataCallback(Marshal.GetFunctionPointerForDelegate((SRanipal_Eye.CallbackBasic)EyeCallback));
            eye_callback_registered = false;
        }
    }

    private void OnDisable()
    {
        Release();
    }

    void OnApplicationQuit()
    {
        Release();
    }

    private void Release()
    {
        if (eye_callback_registered == true)
        {
            SRanipal_Eye.WrapperUnRegisterEyeDataCallback(Marshal.GetFunctionPointerForDelegate((SRanipal_Eye.CallbackBasic)EyeCallback));
            eye_callback_registered = false;
        }
    }

    private void EyeCallback(ref EyeData eye_data)
    {
        eyeData = eye_data;
        
        // do stuff with eyeData..
    }
}

 

 

Hi @Corvus,

I've tried your callback method solution, unfortunately it is still crashing the Unity when I stop the game. Moreover it pretty soon throws a NullReferenceException, usually after a second or so. I attached the image with the exception.
