PlaySteamVRHapticFeedback StartSecondsFromNow parameter ignored

Open CrimsonZen opened this issue 6 years ago • 4 comments

UE4: 4.22.0, source built SteamVR: 1.4.1 beta Plugin branch: develop-4.22 (37097bca) Hardware: Vive, EV3 Knuckles

Tested by calling the blueprint node Play Steam VR Haptic Feedback. All calls appear to treat the StartSecondsFromNow parameter as 0.0f, as haptic playback starts immediately regardless of value.

Thanks @CrimsonZen. Currently investigating.

Confirmed behaviour for release and beta channels of SteamVR. Investigation ongoing.

Looks like this is an underlying issue in OpenVR. The OpenVR API TriggerHapticVibrationAction ignores the fStartSecondsFromNow param.

@kisak-valve Can you move this to the OpenVR repo?

Hi, Any update on this issue? It's still present, StartSecondsFromNow doesn't do anything and the vibration always triggers instantly
