unity-event

Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Hooking up UnityEvents in the Inspector
• Wiring button or trigger callbacks
• Scripting persistent listeners
• 在 Inspector 里挂接 UnityEvent、连接按钮或触发器回调、脚本化持久监听

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.

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	Yes	-	Component name
eventName	string	Yes	-	Event field name (e.g. "onClick")

Returns: { success, gameObject, component, eventName, listenerCount, listeners }

event_add_listener

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

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	Yes	-	Component owning the event
eventName	string	Yes	-	Event field name (e.g. "onClick")
targetObjectName	string	Yes	-	GameObject holding the method to call
targetComponentName	string	No	null	Component on the target, or GameObject to call the object itself
methodName	string	Yes	-	Public method or set_PropertyName
mode	string	No	RuntimeOnly	Off, RuntimeOnly, or EditorAndRuntime
argType	string	No	void	void, int, float, string, or bool
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

Returns: { success, message, index, mode }

Unlike event_set_listener, this skill has no object argType — it only reaches the standard UnityEvent overloads.

index	int	No	0	Listener index

Returns: { success, remainingCount }

Returns: { success, message }

event_clear_listeners

Remove all persistent listeners from a UnityEvent.

Parameter	Type	Required	Default	Description
name	string	No	null	GameObject name
instanceId	int	No	0	GameObject instance ID

Returns: { success, removed }

event_set_listener_state

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

index	int	No	0	Listener index
state	string	No	null	Call state: "Off", "RuntimeOnly", or "EditorAndRuntime"

Returns: { success, index, state }

event_set_listener

Replace a persistent listener at a specific index.

Parameter	Type	Required	Default	Description

index	int	No	0	Listener index to replace
targetName	string	Yes	-	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	Yes	-	Public method or set_PropertyName
mode	string	No	RuntimeOnly	Off, RuntimeOnly, or EditorAndRuntime
argType	string	No	void	void, int, float, string, bool, object
