# For Loop

## Overview

![The For Loop Node.](/files/AckWhdWBrxQnH8x8TpZG)

The **For Loop Node** triggers an iterative process that steps through the provided **Int** inputs. The output can then, for example, be printed to the **Console** or affect the next **Node** in the **Logic Branch**.

[**Scope**](/incari-studio/2023.1/toolbox/overview.md#scopes): **Project**, **Scene**, **Function**, **Prefab**.

| ----------------- | --------- | --------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse** | A standard **Input Pulse**, to trigger the execution of the **Node**. |
| `First Index`     | **Int**   | The starting index.                                                   |
| `Last Index`      | **Int**   | The stopping index.                                                   |

| ------------------ | --------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| *Pulse Output* (►) | **Pulse** | A standard **Output Pulse**, to move onto the next **Node** along the **Logic Branch**, once this **Node** has finished its execution. |
| `Index`            | **Int**   | The output index.                                                                                                                      |
| `OnEnd`(►)         | **Pulse** | A **Pulse** that flows to an action, such as a **Console** message, once the **For Loop** has ended.                                   |
