Wwise in editor mode changes:

IMPORTANT: Don't forget to add WWISE_EDITOR_PREVIEW in Build Settings -> Player Settings -> Scripting Define Symbols to enable Wwise support.

• Add this code to AkBank.cs:

public void LoadInEditor()
{
		Awake();
		Start();
		HandleEvent(null);
}

public void UnloadInEditor()
{
		OnDestroy();
}

• In AkInitializer.cs make these methods public:
  • Awake()
  • OnDestroy()
  • OnEnable()
  • LateUpdate()
  • OnDisable()
• In AkTerminator.cs make these methods public
  • Awake()
  • OnApplicationQuit()
  • OnDestroy()
• Make sure to wrap all DontDestroyOnLoad() methods in if (Application.isPlaying) in AkInitializer.cs and AkTerminator.cs
• Get Wwise events IDs using code from GetWwiseEventIDs.cs (see above) and then just send one of the IDs to Play() method in WwiseEditorPreview.cs (note that in this case it uses string for id, but you can simply change that by removing type cast)
