Question Change Interaction layer Mask With Code

Is there any way to Change Interaction layer Mask With Code?

 

Yep!
You can make a LayerMask variable and use that. It's easiest to have it public/serialized, so you can edit it in Unity, but otherwise it uses flags and it quite flexible.
Google found me this:
https://docs.unity3d.com/ScriptReference/LayerMask.html
https://docs.unity3d.com/Manual/Layers.html

 

Yeah... I understand this, but how can I modify the Interaction layer Mask from another code? How can I call it?
Sure,
"Interaction layer Mask" = myLayer;
but I can't refer to it.

 

Wdym from another code?

 

I mean from another script. I have a pre-made XRGrabInteractable script by XR Interaction Toolkit, and I want to change the Interaction Layer mask variable in this script by my own script. But I don't know how to refer to this variable.

 

gameobject.layer?
https://docs.unity3d.com/ScriptReference/GameObject-layer.html

 

Yes, but actually no. I don't want to change the layer of my game object. I want to change the layers that can interact with the grabbable.

GetComponent<Grabbable>.InteractionLayerMask = MyLayer

If it's private just make it public

 

Yes! That is the solution that I'm looking for, but if I write this script, nothing happen.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR.Interaction.Toolkit;
public class LayerChange : MonoBehaviour
{
public LayerMask RightHand;
void Update()
{
GetComponent<XRBaseInteractable>().interactionLayerMask = RightHand;
}
}

 

Doesn't it update in the inspector as well?
If so, does the code even run?

 

Yes! If I build in a Debug.Log function, it works.

 

What do you mean with the last part?
And if it works there it should just work. Otherwise I cannot help much

 

You should try something like this:

interactableObject.interactionLayers = InteractionLayerMask.GetMask("Default");

Where the interactableObject must implement the IXRInteractable interface, so for example be of type XRBaseInteractable which implements that interface by default.
The parameter(s) in GetMask are defined interaction layers.
But keep in mind: those interaction layers from the XR Interaction Toolkit are different from normal layers, so don't mix them up!

 

Thank you so much. Spent all yesterday evening puzzling over this. Kept ending up with the traditional Layers information. It worked a treat! Just come back to it this evening and it worked.

 

Hello, I am having a similar issue but also cannot figure it out, I am trying to swap the layermask used in order to be able to distance grab with rays, this would be possible if the layermask was set to ''Default''. It is giving me an error message 'InteractionlayerMask' could not be found (are you missing a using directive or an assembly reference). This is my code

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.XR.Interaction.Toolkit;
3.  
4. /// <summary>
5. /// Set the interaction layer of an interactor
6. /// </summary>
7. public class SetInteractionLayer : MonoBehaviour
8. {
9.     [Tooltip("The layer that's switched to")]
10.     public InteractionLayerMask targetLayer = 0;
11.  
12.     private XRBaseInteractor interactor = null;
13.     private InteractionLayerMask originalLayer = 0;
14.  
15.     private void Awake()
16.     {
17.         interactor = GetComponent<XRBaseInteractor>();
18.         originalLayer = interactor.interactionLayers;
19.     }
20.  
21.     public void SetTargetLayer()
22.     {
23.         interactor.interactionLayes = targetLayer;
24.     }
25.  
26.     public void SetOriginalLayer()
27.     {
28.         interactor.interactionLayers = originalLayer;
29.     }
30.  
31.     public void ToggleTargetLayer(bool value)
32.     {
33.         if (value)
34.         {
35.             SetTargetLayer();
36.         }
37.         else
38.         {
39.             SetOriginalLayer();
40.         }
41.     }
42.  
43. }
44.  

 

So happy I came across this 6 years later. Thanks
