Reload Listeners

dev.architectury.registry.ReloadListenerRegistry

Register a resource/data reload listener - code that runs when resource packs or data packs are (re)loaded - so you can load your own custom JSON resources or data.

Registering a listener

ReloadListenerRegistry.register(
    PackType.SERVER_DATA,          // data packs (use CLIENT_RESOURCES for resource packs)
    new MyDataReloadListener(),    // your PreparableReloadListener
    Identifier.fromNamespaceAndPath(MyMod.MOD_ID, "my_data")
);

• The PackType selects which side reloads trigger the listener: SERVER_DATA for data packs, CLIENT_RESOURCES for resource packs.
• The Identifier is a unique id for your listener.

Ordering with dependencies

An overload accepts a Collection<Identifier> of other listener ids that must run before yours, so you can depend on their results:

ReloadListenerRegistry.register(
    PackType.SERVER_DATA,
    new MyDataReloadListener(),
    Identifier.fromNamespaceAndPath(MyMod.MOD_ID, "my_data"),
    List.of(Identifier.fromNamespaceAndPath(MyMod.MOD_ID, "my_other_data"))
);
