    Hi everyone,

    It's my first thread on the forum, I would like to have some help concerning the chaperone when using my VR headgear, is there a way to modify/ manipulate it via a C# script ? I would like to manipulate it when my application is ongoing.

    Thank you in advance for your help,

    Best regards,

    Hi,
    I don't think there is a way to manipulate guardians/chaperone via script for Oculus devices, since guardian boundary is also a safety feature that help you stay within your cleared play area.
    But I am curious the use cases that need to manipulate it via script if you could share?

    Thanks,
    Tanya

    Hi Tanya,

    Thank you for your answer, I forgot to reply ^^', as you said, there is no way to access by script the chaperone, but I somehow resolved my problem by accessing the Play Area via SteamVR.

    "But I am curious the use cases that need to manipulate it via script if you could share?"

    - I wanted to maybe create an animation by using the chaperone, or at least be able to disable it whenever I want to. For example, when I push a button or something like this.

    Thank you for you help,
    Guillaume

    You could check out OculusBoundary.cs within Oculus XR plugin. (install XR Plug-in Management --> choose Oculus checkbox under Plug-in Providers)
    There are public APIs like below:

    Code (CSharp):
    1. /// <summary>
    2. /// Requests that the boundary system visibility be set to the specified value.
    3. /// The actual visibility can be overridden by the system (i.e., proximity trigger) or by the user (boundary system disabled)
    4. /// </summary>
    5. public static void SetBoundaryVisible(bool boundaryVisible)
    6.  
    7. /// <summary>
    8. /// Get a vector of the spatial dimensions of the specified boundary type. (x = width, y = height, z = depth) with height always returning 0.
    9. /// Return true if boundary dimensions are supported and values are available. Return false otherwise.
    10. /// </summary>
    11. public static bool GetBoundaryDimensions(BoundaryType boundaryType, out Vector3 dimensions)
    Besides, XRInputSubsystem also provided an API to obtain guardian geometry/points:
