# For Loop

## Overview

![The For Loop Node.](/files/NOtwRtpgrCoXJSWCW7CB)

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**.

## Attributes

| Attribute                | Type     | Description                                                                |
| ------------------------ | -------- | -------------------------------------------------------------------------- |
| `First Index`            | **Int**  | The starting index.                                                        |
| `Last Index`             | **Int**  | The stopping index.                                                        |
| `Step`                   | **Int**  | The amount to increase or decrease by.                                     |
| `Is Last Index Included` | **Bool** | Notes whether the last index is included or excluded during the iteration. |

## Inputs

| Input             | Type      | Description                                                           |
| ----------------- | --------- | --------------------------------------------------------------------- |
| *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.                                                   |
| `Step`            | **Int**   | The amount to increase or decrease by.                                |

## 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. |
| `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.                                   |
