Event Skills

Inspect and modify persistent listeners on UnityEvents (e.g. Button.onClick, Toggle.onValueChanged) — the same listeners you see in the Inspector's event drop slots.

Operating Mode

Approval：查询类 skill（event_get_listeners / event_list_events / event_get_listener_count，源码标 SkillMode.SemiAuto）直接执行；其余变更/调用类（event_add_listener / event_set_listener / event_set_listener_state / event_invoke / event_add_listener_batch / event_copy_listeners，标 SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。
Auto / Bypass：未被禁列表拦截的 skill 直接执行。
本模块含 Delete 类 skill：event_remove_listener、event_clear_listeners 标记为 SkillOperation.Delete，被 IsForbiddenInSemi 静态拦截 —— 仅 Bypass 模式或加入 Allowlist 才能调用。
event_invoke 只在 Play mode / runtime 下有效；编辑器空跑时仅触发 EditorAndRuntime 监听。event_add_listener 等写入的是 persistent listener（序列化到 prefab/scene），即可在编辑器时配置。

DO NOT (common hallucinations):

event_create / event_trigger do not exist → UnityEvents are declared in component source code; this module only wires listeners
event_subscribe does not exist → use event_add_listener
event_remove does not exist → use event_remove_listener
event_add_listener requires exact component type and method name on the target

Routing:

For XR interaction events → use xr module's xr_add_interaction_event
For C# event code → write via script module

Skills

`event_get_listeners`

Get persistent listeners of a UnityEvent. Parameters:

name / instanceId / path: Target GameObject locator.
componentName (string): Component name.
eventName (string): Event field name (e.g. "onClick").

`event_add_listener`

Add a persistent listener to a UnityEvent (Editor time). Parameters:

name / instanceId / path, componentName, eventName: Target event.
targetObjectName, targetComponentName, methodName: Method to call.
mode (string, optional): "RuntimeOnly", "EditorAndRuntime", "Off".
argType (string, optional): "void", "int", "float", "string", "bool".
floatArg, intArg, stringArg, boolArg: Argument value if needed.

`event_remove_listener`

Remove a persistent listener by index. Parameters:

name / instanceId / path, componentName, eventName: Target event.
index (int): Listener index.

`event_invoke`

Invoke a UnityEvent explicitly (Runtime only). Parameters:

name / instanceId / path, componentName, eventName: Target event.

`event_clear_listeners`

Remove all persistent listeners from a UnityEvent.

Returns: { success, removed }

`event_set_listener_state`

Set a listener's call state (Off, RuntimeOnly, EditorAndRuntime).

Returns: { success, index, state }

`event_set_listener`

Replace a persistent listener at a specific index.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | name | string | No | null | GameObject name | | instanceId | int | No | 0 | GameObject instance ID | | path | string | No | null | GameObject hierarchy path | | componentName | string | No | null | Source component name | | eventName | string | No | null | Event field name | | index | int | No | 0 | Listener index to replace | | targetName | string | No | null | Target GameObject name | | targetInstanceId | int | No | 0 | Target GameObject instance ID | | targetPath | string | No | null | Target hierarchy path | | targetComponentName | string | No | null | Target component name, or GameObject | | methodName | string | No | null | Public method or set_PropertyName | | mode | string | No | RuntimeOnly | Off, RuntimeOnly, or EditorAndRuntime | | argType | string | No | void | void, int, float, string, bool, object | | floatArg | float | No | 0 | Static float argument | | intArg | int | No | 0 | Static int argument | | stringArg | string | No | null | Static string argument | | boolArg | bool | No | false | Static bool argument | | objectReferenceName | string | No | null | Scene object argument name | | objectReferenceInstanceId | int | No | 0 | Scene object argument instance ID | | objectReferencePath | string | No | null | Scene object argument path | | objectAssetPath | string | No | null | Project asset argument path | | objectType | string | No | null | Object/component type for object argument |

Returns: { success, index, target, targetType, method, state, argType }

`event_list_events`

List all UnityEvent fields on a component.

Returns: { success, component, count, events }

`event_add_listener_batch`

Add multiple listeners at once. items: JSON array of {targetObjectName, targetComponentName, methodName}.

Returns: { success, added, total }

`event_copy_listeners`

Copy listeners from one event to another.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | sourceObject | string | Yes | - | Source GameObject name | | sourceComponent | string | Yes | - | Source component name | | sourceEvent | string | Yes | - | Source event field name | | targetObject | string | Yes | - | Target GameObject name | | targetComponent | string | Yes | - | Target component name | | targetEvent | string | Yes | - | Target event field name |

Returns: { success, copied }

`event_get_listener_count`

Get the number of persistent listeners on a UnityEvent.

Returns: { success, count }
