## Overview

![The On ImageSequence Frame Changed Node.](/files/UV0YU5FQsWamdTjxOfOs)

**On ImageSequence Frame Changed** is an **Event Listener** **Node** used for executing a **Logic Branch** when the frame of an **Image Sequence** changes.

[**Scope**](/incari-studio/2023.2/toolbox/overview.md#scopes): **Scene**, **Prefab**.

| Attribute | Type         | Description                                                                                                                     |
| --------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------- |
| `Object`  | **ObjectID** | **Image Sequence** in which a frame change triggers the **Logic Branch**, if none is given in the `Object ID` **Input Socket**. |

## Inputs

| Input           | Type         | Description                                                                        |
| --------------- | ------------ | ---------------------------------------------------------------------------------- |
| `Object ID`     | **ObjectID** | **Image Sequence** in which a frame change triggers the **Logic Branch**.          |
| `Subscribe` (►) | **Pulse**    | An **Input Pulse** that needs to be triggered to start listening to the **Event**. |

## Outputs

| Output             | Type         | Description                                                                                                                                                                                                            |
| ------------------ | ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| *Pulse Output* (►) | **Pulse**    | A standard **Output Pulse**, to move onto the next **Node** along the **Logic Branch**, once this **Node** has finished its execution.                                                                                 |
| `#Frame`           | **Int**      | Frame number within the sequence.                                                                                                                                                                                      |
| `Object ID`        | **ObjectID** | The **Image Sequence** received as **Input**.                                                                                                                                                                          |
| `Event ID`         | **ObjectID** | The ID of the current **Event**. This can be connected to the [**Unsubscribe Node**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2023.2/toolbox/incari/event/unsubscribe.md) to unsubscribe from the **Event**. |
