Hi, I would like to read the volume of a voiceover asset as it’s playing. There’s no obvious way from the docs or looking at the blueprint classes in UE4. I see there’s a BP node, “Get Parameter”, that promises to return a float. Which I assume comes from the method here FMOD - API | ufmodaudiocomponent getparameter
But how do i get the float to return anything? What parameters are available? Looking at the class yielded nothing. The parameter cache was noted in the API docs, so I thought to get the array of key names from the FMOD Audio component object reference(i only saw it in API docs, blueprint docs are missing for FMOD 2.00.06). I printed the length and iterated the array of key names to the UE4 output log.
This returned an output of:
FMOD PARAMETER ARRAY LENGTH :: 0 FMOD PARAMETER :: END
Which tells me there’s nothing there ? ? ?
Ideally, I’d like return the volume. But if I can set a curve in the event within FMOD Studio or read whether the timeline has an asset on it, that would be good enough.
Can anyone help me in my quest?
