XR Emitter

Events emitter is a wrapper over Unity's XR Interaction Toolkit that provides an easy-to-use way to interact with XR events.

Right now, XREmitter helps to get events from hand controllers (a list of the events).

How to set up it

Assume that you already set up XR Toolkit and added XR Rig to your scene.

1. Import XREmitter.unityasset into your project;

2. Add XREmitterR and/or XREmitterL component to Right/Left Controller in your scene;

3. Assign XRControllers to the components accordingly;

4. Subscribe your method to an event stream.

How to use it

Here is a simple example of how the XREmitter can be used.

Note, XREmitter's events are static, so you don't need to have a reference to an object.

(Look at the XR Emmiter Demo/Assets/Scenes/Demo 2.unity to see the example in action.)

using UnityEngine;

public class CubeManager : MonoBehaviour
{
    [SerializeField] private GameObject cube;
    private bool _lastTriggerButtonState = true;
    
    // Subscribe a method to an event stream
    private void OnEnable() 
    {
        XREmitterR.OnTriggerButtonPressed += SetBoxVisability;
    }

    // A good practice to unsubscribe a method when its object is gone
    private void OnDisable() 
    {
        XREmitterR.OnTriggerButtonPressed -= SetBoxVisability;
    }

    // The signature of the method the same as the event stream we want to subscribe to.
    private void SetBoxVisability (bool b) 
    {
        if (_lastTriggerButtonState == b) return;
        _lastTriggerButtonState = b;

        cube.gameObject.SetActive(!b);
    }
}

Events List

<T> defines a data type that is going to be passed to a subscribed method.

public static event Action<float>   OnTriggerIntensity;
public static event Action<bool>    OnTriggerButtonPressed;
public static event Action<bool>    OnPrimaryButtonPressed;
public static event Action<bool>    OnPrimaryButtonTouched;
public static event Action<bool>    OnSecondaryButtonPressed;
public static event Action<bool>    OnSecondaryButtonTouched;
public static event Action<float>   OnGripIntensity;
public static event Action<bool>    OnGripPressed;
public static event Action<Vector2> OnPrimary2DAxis;
public static event Action<bool>    OnPrimary2DAxisPressed;
public static event Action<bool>    OnPrimary2DAxisTouched;
