ParamRef doesn't show local parameters in Unity

Unity

I can’t see any of my local parameters in the Unity ParamRef browser. Is that by design? Is there any way to see their names from unity’s editor?

Just to clarify- are you doing something like:

[FMODUnity.ParamRef]
public string myParam;

and asking why you can’t see local parameters? If so, the FMODUnity.ParamRef attribute is intended to be used on global parameters. This does make sense as a limitation because if you could see local parameters globally, they would no longer be local. A good way to see which parameters are available on which events, and to audition them within the Unity Editor, is to use the Event Browser.

Oh awesome! I wasn’t aware of the Event Browser. I’ll just use:
EventManager.EventFromPath();

And then read the local parameters from there. Thank you!

Hi Jeff. So how can we create a refference to the the fmod local parameter to use in code if we can’t use [ParamRef] ?

You can get a list of event-level parameters by calling EventReference.GetEventDescription on a Studio Event Emitter instance to get the underlying EventDescription object, and from there you can get a count of parameters using EventDescription.getParameterDescriptionCount, and iterate over them using EventDescription.getParameterDescriptionByIndex to build up a list of PARAMETER_DESCRIPTION.
From these parameter descriptions, you have access to their names, min-max values etc, which you can use to pass into EventInstance.setParameterByName.
