Changing Snapshot parameters

Unity
1

Hello!

I found some topics about it, but couldn’t find a solution that works.

Basically I have a snapshot that creates a bullet time-like effect once activated, so all game sounds should be affected by it. However, for this effect I created a logic in Unity that should change the effect intensity based on how long the player holds a certain key.
In the FMOD Mixer Window, I created the parameter by right clicking on the Intensity and exposing the parameter as a local variable (I tried switching to global variable but it didn’t work).
I’ve already setup everything I should to work with snapshots:

  • I created the snapshot’s instance using RuntimeManager.CreateInstance(snapshot);
  • I called the method snapshotInstance.setParameterByName(IntensityParameterName, intensity);, here IntensityParameterName equals to “Intensity” (the same name of the FMOD parameter) and intensity is the value that should be updated every n seconds

That said, I’m not getting the effect I wanted. IS there something else I should be doing? :thinking:

Here’s a print of my FMOD Mixer window.

EDIT:

One thing I forgot to mention is: the RuntimeManager.CreateInstance(snapshot) part is setup inside a scriptable object. Not sure if that’s relevant.

Hmm… I can’t see anything in your description of what you’re doing that sounds obviously wrong.

Have you tried calling Studio::EventInstance::getParameterByName after each time you set the parameter, to see whether it returns the values you expect?

Hey, thanks for the reply.

I did, yes. I used the out var value of the get method and tried to log using Debug.Log, but it returns 0 everytime even though the set value is not.

How is that possible? :face_without_mouth:

Are there any other options I could try?

That suggests that the value of the parameter is not being set correctly, possibly because your code is failing to correctly specify the target event instance or parameter.

Is the Studio::EventInstance::setParameterByName function returning FMOD_ERR_INVALID_PARAM or FMOD_ERR_EVENT_NOTFOUND?
