Use event_add_listener with the target GameObject locator, component name, event field name, and the target object, component, and method to call. It writes a persistent listener serialized to the scene or prefab, the same as wiring it in the Inspector.

Call event_add_listener on the Button component's onClick event, specifying the target GameObject, component, and public method name. You can also set the call mode to RuntimeOnly or EditorAndRuntime and pass static arguments if the method needs them.

Yes, event_add_listener_batch accepts a JSON array of target object, component, and method entries and adds them all to one event in a single call. It returns the number of listeners successfully added.

event_remove_listener and event_clear_listeners are marked as Delete operations and are blocked in semi-automatic mode. They only execute in Bypass mode or when the skill is added to the allowlist.

event_invoke only fully works in Play mode or at runtime. In the editor it only triggers listeners whose call state is EditorAndRuntime, so RuntimeOnly listeners will not fire outside Play mode.

Persistent listeners are serialized UnityEvent callbacks stored in scenes and prefabs and visible in the Inspector, which is what this skill manages. C# event subscriptions in code are handled separately through the script module, not this one.
