Check for support at runtime

Not all devices and platforms support every type of marker. Before building features that rely on a specific marker type, you should check whether the current device supports it. To check whether the current device supports a specific marker type, query the XRMarkerSubsystemDescriptor.supportedMarkerTypes property.

XRMarkerSubsystemDescriptor.supportedMarkerTypes returns a Result which indicates whether the platform supports marker tracking. If the platform supports marker tracking, XRMarkerSubsystemDescriptor.supportedMarkerTypes returns a ReadOnlyListSpan of the supported XRMarkerTypes.

The following code example shows how to check which marker types a platform supports:

void GetSupportedMarkerTypes(ARMarkerManager manager)
{
    if (manager.subsystem is XRMarkerSubsystem markerSubsystem)
    {
        var result = markerSubsystem.subsystemDescriptor.supportedMarkerTypes;
        if (result.status.IsError())
        {
            // Handle error
            return;
        }

        var supportedMarkerTypes = result.value;
    }
}
