Mod Loader/Reference/Purchase sound API

The shop plays one sound after a successful fabric or accessory purchase and another when the player cannot afford it. This API changes those two sound banks; it does not change the soundtrack.

Add a sound

Wait for the sound controller before accessing its clips. The example removes one original success clip and registers a replacement from an AssetBundle.

Methods and values

PurchaseSound.Success: Sound played when the purchase succeeds.
PurchaseSound.NotEnoughGold: Sound played when the player cannot afford the purchase.
bool IsReady: True after the sound controller is ready.
IDisposable WhenReady(Action callback): Runs the callback when the sound controller is ready, or immediately if it already is. Dispose to cancel a callback that has not run yet.
AudioClip[] GetOriginalClips(PurchaseSound sound): Returns a copy of the game's original clips for that outcome.
AudioClip[] GetClips(PurchaseSound sound): Returns a copy of the clips currently available for that outcome.
IDisposable AddClip(PurchaseSound sound, string id, AudioClip clip): Adds a clip to the bank. IDs must be unique across loaded plugins. Dispose the handle to remove it.
bool RemoveClip(PurchaseSound sound, string id): Removes a clip registered through this API. Returns false if the ID is unknown.
IDisposable SuppressClip(PurchaseSound sound, AudioClip clip): Hides a clip until the handle is disposed. Keep one handle for each original clip you suppress.

If every clip in a bank is suppressed, that purchase outcome is silent. Keep custom clips and their AssetBundle loaded while registered.
