OpenVRInputTest

A working example of listening to SteamVR input v2 using C#

This is a console application that will report incoming events.

It was used to very slowly get a working integration of the SteamVR input system introduced in 2018. Finally in 2020, by talking to a range of people, this test implementation finally became functional.

Build for 64bit and it should just work, in theory.

Key thing learned

Things that I don't think the OpenVR wiki told me very clearly.

• Need to include and load a app.vrmanifest with AddApplicationManifest()
• Make sure to provide the proper action-set handle in the VRActiveActionSet_t when running UpdateActionState()
• Last parameter in GetDigitalActionData() is not a device index, but a handle, can be set to 0 for no filter
