Trying to use csMonitor code

[Hightree]

Hi there,
I'm trying to use the C# example inside of Unity3D.
Unfortunately when trying to hook up the callback functions, I get the following error code :

Code: Select all

NotSupportedException: non imported interfaces on imported classes is not yet implemented.
(wrapper cominterop) TDx.TDxInput._ISensorEvents_Event:add_SensorInput (TDx.TDxInput._ISensorEvents_SensorInputEventHandler)

I'm no interop or COM ninja, does anybody have any ideas on how to get round this ?

Thanks in advance, Patrick

Here is a Unity3D plugin for the SpaceNavigator:

Thanks for the pointer, I found the plugin too this weekend.
But the programmer in me wants to write this plugin himself

I'm getting the same error and i'd also like to know how to resolve this, that plugin for unity costs $70 which is priced way to high for me.

In the end I got it working by using the code from that sample, but leaving out the COM event stuff.
Instead I am polling the device for its current values in my EditorWindow's Update function.

My plugin is functional by now and I am planning to open source it soon.
It just needs to be cleaned up a bit, should be done within a couple of weeks.

P.S.
I should have posted the solution when I found it, sorry for that.

Hi Hightree, could you give any tip for get data in Update function?
In C# sample, I could remove all event and get data when ever I want. But in Unity, I try to get data in Update function, but it always zero

Strange, maybe there's something going wrong in the initialization phase.
Here's my windows implementation of the device handling:

Code: Select all

using System;
using System.Runtime.InteropServices;
using TDx.TDxInput;
using UnityEngine;

class SpaceNavigatorWindows : SpaceNavigator {	
	// Public API
	public override Vector3 GetTranslation() {
		float sensitivity = Application.isPlaying ? PlayTransSens : TransSens;
		return (SubInstance._sensor == null ?
			Vector3.zero :
			new Vector3(
				LockTranslationX || LockTranslationAll ? 0 : (float)SubInstance._sensor.Translation.X,
				LockTranslationY || LockTranslationAll ? 0 : (float)SubInstance._sensor.Translation.Y,
				LockTranslationZ || LockTranslationAll ? 0 : -(float)SubInstance._sensor.Translation.Z) *
				sensitivity * TransSensScale);
	}
	public override Quaternion GetRotation() {
		float sensitivity = Application.isPlaying ? PlayRotSens : RotSens;
		return (SubInstance._sensor == null ?
			Quaternion.identity :
			Quaternion.AngleAxis(
				(float)SubInstance._sensor.Rotation.Angle * sensitivity * RotSensScale,
				new Vector3(
					LockRotationX || LockRotationAll ? 0 : -(float)SubInstance._sensor.Rotation.X,
					LockRotationY || LockRotationAll ? 0 : -(float)SubInstance._sensor.Rotation.Y,
					LockRotationZ || LockRotationAll ? 0 : (float)SubInstance._sensor.Rotation.Z)));
	}

	// Device variables
	private readonly Sensor _sensor;
	private readonly Device _device;
	//private readonly Keyboard _keyboard;

	#region - Singleton -
	/// <summary>
	/// Private constructor, prevents a default instance of the <see cref="SpaceNavigatorWindows" /> class from being created.
	/// </summary>
	private SpaceNavigatorWindows() {
		try {
			if (_device == null) {
				_device = new DeviceClass();
				_sensor = _device.Sensor;
				//_keyboard = _device.Keyboard;
			}
			if (!_device.IsConnected)
				_device.Connect();
		}
		catch (COMException ex) {
			Debug.LogError(ex.ToString());
		}
	}

	public static SpaceNavigatorWindows SubInstance {
		get { return _subInstance ?? (_subInstance = new SpaceNavigatorWindows()); }
	}
	private static SpaceNavigatorWindows _subInstance;
	#endregion - Singleton -

	#region - IDisposable -
	public override void Dispose() {
		try {
			if (_device != null && _device.IsConnected) {
				_device.Disconnect();
				_subInstance = null;
				GC.Collect();
			}
		}
		catch (COMException ex) {
			Debug.LogError(ex.ToString());
		}
	}
	#endregion - IDisposable -
}

Hope this helps.

Thanks Hightree, your code help he to easy get value in Unity3D, just add close connection at onQuit
Here is my code, hope this helpful for someone

Code: Select all

using UnityEngine;
using System.Collections;
using System;
using System.Runtime.InteropServices;
using TDx.TDxInput;

public class SpaceNavigator : MonoBehaviour {
	
	private Sensor sensor; 
	private Device device;
	private Keyboard keyboard;
	void Start () {
		

        device = new DeviceClass();
        sensor = device.Sensor;
        keyboard = this.device.Keyboard;
        device.Connect();
	}
	void Update () {
		var translation = sensor.Translation;
		var rotation = sensor.Rotation;
		Debug.Log("tx: "+(translation.X*1000.0).ToString()+",ty: "+translation.Y.ToString()+",tz: "+translation.Z.ToString());
		Debug.Log("rx: "+rotation.X.ToString()+",ry: "+rotation.Y.ToString()+",rz: "+rotation.Z.ToString()+",rs: "+rotation.Angle.ToString());
        System.GC.Collect();
	}
	
    void OnApplicationQuit() {
         if (device != null && device.IsConnected) {
            device.Disconnect();
            GC.Collect();
         }
	}
}

My driver is functional and released out into the wild
I've published it here on the Unity forum and the source code is available on Github.
