I’m interested in creating a script to automatically import a set of audio clips from an assets folder, and create a new scriptable object for each clip. The type of ScriptableObject I am creating is an AudioCue ripped straight out of the Unity Open Project (Chop Chop)
I’ve gotten 95% of the script complete, but I’m encountering a difficulty:
Each AudioCueSO I’m creating contains at least one referenceto an AudioClip.
I can load these clips directly by making a UnityWebRequestMultiMedia.GetAudioClip().
Unfortunately, when the script runs, each new AudioCueSO has Type mismatch printed where the loaded AudioClip should be. I’m wondering what the proper way to instantiate scriptable objects with specific audioclip or prefab references is via script?
/// <summary>
/// The purpose of this scriptable object is to make a widget for automatically creating AudioCues from
/// AudioClips by simply providing a directory. This enables batch creation of AudioCueSO.
