**On Mouse Button Up** is an **Event Listener** **Node** used for executing a **Logic Branch** when a mouse button is released, either on a particular **Object** or anywhere in the **Screen**.

The **Attributes** allow the user to choose which mouse button will trigger the **Event** and whether the `Event Base` is a specific **Object** or the entire **Screen**.

[**Scope**](https://docs.incari.com/incari-studio/overview#scopes): **Scene**, **Prefab**.

| Input           | Type         | Description                                                                        |
| --------------- | ------------ | ---------------------------------------------------------------------------------- |
| `Object ID`     | **ObjectID** | The **Object** in which releasing a button 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.                                                                     |
| `Object ID`        | **ObjectID** | The **Object ID** of the **Object** where the mouse button was released. If there is no **Object** on that part of the **Screen**, the output is the **Object ID** `00000000-0000-0000-0000-000000000000`. |
