# Event Nodes Emit messages and status updates from graphs, and react to scene events with the **Event** listener node. See [Events](../../core-concepts/events.md) for the event system and the [Events reference](../events.md) for every event a graph can listen to. _7 nodes._ | Node | Registry path | | --- | --- | | [Emit Agent Message](#emit-agent-message) | `event/EmitAgentMessage` | | [Emit Scene Status](#emit-scene-status) | `event/EmitSceneStatus` | | [Emit Status](#emit-status) | `event/EmitStatus` | | [Emit Status (Conditional)](#emit-status-conditional) | `event/EmitStatusConditional` | | [Emit System Message](#emit-system-message) | `event/EmitSystemMessage` | | [Emit World Editor Sync](#emit-world-editor-sync) | `event/EmitWorldEditorSync` | | [Event](#event) | `event/Event` | ## Emit Agent Message `event/EmitAgentMessage` Emits an agent message to the UX **Inputs** | Input | Type | Description | | --- | --- | --- | | `state` | `any` | The graph state | | `message` | `str` | (optional) The message text to emit | | `agent` | `agent,str` | (optional) The agent (agent object or agent name) | | `header` | `str` | (optional) The header of the message | | `message_color` | `str` | (optional) The color of the message | | `meta` | `dict` | (optional) The meta data of the message | **Outputs** | Output | Type | Description | | --- | --- | --- | | `state` | `any` | The state input, passed through | | `emitted` | `bool` | Whether the message was emitted (True) or not (False) | **Properties** | Property | Type | Default | Description | | --- | --- | --- | --- | | `message` | `str` | `""` | The message text to emit | | `agent` | `str` | `""` | The agent the message is attributed to.

Choices are generated at runtime. | | `meta` | `dict` | `{}` | The meta data of the message | ## Emit Scene Status `event/EmitSceneStatus` Emits the scene status object to the UX **Inputs** | Input | Type | Description | | --- | --- | --- | | `state` | `any` | The graph state | **Outputs** | Output | Type | Description | | --- | --- | --- | | `state` | `any` | The state input, passed through | ## Emit Status `event/EmitStatus` Emits a status message **Inputs** | Input | Type | Description | | --- | --- | --- | | `message` | `str` | (optional) The message text to emit | | `status` | `str` | (optional) The status of the message | | `as_scene_message` | `bool` | Whether to emit the message as a scene message (optional) | **Outputs** | Output | Type | Description | | --- | --- | --- | | `emitted` | `bool` | Whether the message was emitted (True) or not (False) | **Properties** | Property | Type | Default | Description | | --- | --- | --- | --- | | `message` | `str` | `""` | The message text to emit | | `status` | `str` | `"info"` | The status of the message. Choices are generated at runtime. | | `as_scene_message` | `bool` | `False` | Whether to emit the message as a scene message | ## Emit Status (Conditional) `event/EmitStatusConditional` Emits a status message if a condition is met Unlike EmitStatus, the `state` input is required, so the message is only emitted when the state input actually receives a value - connect it through a conditional branch to gate the emission. **Inputs** | Input | Type | Description | | --- | --- | --- | | `state` | `any` | The graph state | | `message` | `str` | (optional) The message text to emit | | `status` | `str` | (optional) The status of the message | | `as_scene_message` | `bool` | Whether to emit the message as a scene message (optional) | **Outputs** | Output | Type | Description | | --- | --- | --- | | `state` | `any` | The graph state | | `emitted` | `bool` | Whether the message was emitted (True) or not (False) | **Properties** | Property | Type | Default | Description | | --- | --- | --- | --- | | `message` | `str` | `""` | The message text to emit | | `status` | `str` | `"info"` | The status of the message.

Choices are generated at runtime. | | `as_markdown` | `bool` | `False` | Whether to render the message as markdown | ## Emit World Editor Sync `event/EmitWorldEditorSync` Sends a world editor sync message which on the UX side will cause the world editor to sync its state with the server This is useful when the world editor needs to be updated with the latest state. **Inputs** | Input | Type | Description | | --- | --- | --- | | `state` | `any` | | **Outputs** | Output | Type | Description | | --- | --- | --- | | `state` | `any` | | ## Event `event/Event` Returns the current event object when inside a Listen node module. **Outputs** | Output | Type | Description | | --- | --- | --- | | `event` | `event` | The current event object |
