# Set Current Index

## Overview

![The Set Current Index Node.](/files/Zp9OEM5O4WGbT55QLhuV)

**Set Current Index** selects an entry item by using its index. It accepts a **List** **Object** and an `Index` value and selects an entry item corresponding to the `Index` value.

The index count starts from zero, which means that the `Index` of the last entry item of the **List** **Object** is equal to the total number of entry items minus one ("sum of entries" - 1). This follows from array-based indexing where the index of the first entry is 0.

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

| --------- | ------- | ---------------------------------------------------------------------------------- |
| `Index`   | **Int** | The default `Index` value if no value is provided to the input `Index` **Socket**. |

| ----------------- | ------------ | ------------------------------------------------------------------------------------ |
| *Pulse Input* (►) | **Pulse**    | A standard **Input Pulse**, to trigger the execution of the **Node**.                |
