Getting Vector2f inputs

OpenXR
1

I’m nearly done with my OpenXR implementation, in less than 1000 lines of code. I have boolean, value, and pose inputs working, but have hit a problem with vector2f inputs. I am using an Oculus touch controller.

In the XrInteractionProfileSuggestedBinding structure, interactionProfile is set to “/interaction_profiles/oculus/touch_controller” and the suggestedBindings member contains these two values:

  • “/user/hand/right/input/thumbstick/x”
  • “/user/hand/right/input/thumbstick/y”

I am not declaring any subaction values.

I expect the program to fill in the values for the XrActionStateVector2f value when xrGetActionStateVector2f is called, but the value is always (0.0, 0.0). I am checking the return values of all OpenXR commands and they are always XR_SUCCESS. All other types of inputs are working as expected.

I also tried setting suggestedBindings to a single value “/user/hand/right/input/thumbstick”, with the same result.

Do I misunderstand how vector2f inputs are supposed to work in OpenXR? The tutorial I am following leaves this topic out:

When I removed all other actions from my config file, it started working as expected. So probably another action definition was overwriting the thumbstick’s functionality.
