Hi, total newbie to Unity and I’m currently following the 2D game kit FMOD tutorial [https://www.youtube.com/watch?v=bLjfG-0YGZ0](https://www.youtube.com/watch?v=bLjfG-0YGZ0)

I’ve followed along and now just testing the footsteps work in Unity, but this error is popping up each time it hits the animation event to trigger the sound…

NotImplementedException: The requested feature is not implemented. FMOD.Studio.EventInstance.setParameterValue (System.String v, Single material) (at Assets/Plugins/FMOD/src/Runtime/wrapper/fmod\_studio.cs:1345) FMOD\_Player.PlayFootstepsEvent (System.String path) (at Assets/FMOD\_Player.cs:40)

Does anyone have any suggestions/able to explain what this means?

In FMOD 2.0, there have been some changes made to the Parameter API which you can read more about here: [https://fmod.com/resources/documentation-api?version=2.0&page=welcome-whats-new-200.html#new-parameter-api](https://fmod.com/resources/documentation-api?version=2.0&page=welcome-whats-new-200.html#new-parameter-api)

Basically `EventInstance.setParameterValue` does not exist anymore, you will need to use either:

- `setParameterByName`
- `setParameterByID`
