A small bit of Unity code to crossfade snapshots based on which audiosource the player is facing.
- This script uses Camera.Main (got once in the start method). You'll need a camera tagged as "MainCamera".
- Make Mixer groups for each audio source you'll be controlling.
- Assign these mixer groups in the audio source's inspector.
- Position your sources in different places, I did mine north, south, east, and west.
- Make snapshots for each source, where everything except its group are turned down fully.
- Add a DirectionalAudioSnapshotSwitcher
- I've made a right click context menu on the DirectionalAudioSnapshotSwitcher component, this will set up 4 snapshot entries for North, South, East, and West. Totally optional, but a timesaver for this example use case.
- Assign the fields for each AudioSnapShotData in the inspector (e.g.the transform for the north audio source, and north snapshot)
Hopefully press play, and you'll see changes when you turn the camera (either through a player script, VR, or grabbing the transform in scene view.
