Godot Version

4.5.1

Question

I am running Godot 4.5.1 on Kubuntu and have my Valve Index setup on it. I have SteamVR switched on with both controllers and the HMD tracking, and Godot is able to track the controllers in my game, but it cant seem to detect any input from any of the buttons. The SteamVR controller management shows all buttons being detected normally.

I have XR enabled in my project settings of course. And I’ve tried some blanket _input(event) output, but get nothing. The Godot Input detector doesnt detect anything when pressing the buttons or moving the joysticks. And I have my Inputs setup to detect the general joystick inputs for controllers, so assuming the VR inputs should come through for these Inputs, they do not fire for my Index controllers but work fine for my Steam Deck joysticks.

Does anyone have any thoughts on how I can work around this?

Hey Aaron,

Due to the unique requirements and limitations of the OpenXR action map, the XR input system is separate from Godots traditional input system.

You can setup your OpenXR actions in the OpenXR action map found at the bottom of the screen.

Then on the XRController3D node for each of your controllers, you will find methods to obtain different action states for all action inputs bound to that controller.

You can also read more about it in the manual: The XR action map — Godot Engine (stable) documentation in English

Ah ok, I didn’t consider it might just work differently for XR and assumed I’d encountered some kind of issue with my setup. Thanks for the response and the info!

You are not the first, and will likely not be the last to run into this. It’s not the ideal situation but its the best compromise we had.
