# CharCodeAt

## Overview

![The CharCodeAt Node.](/files/rkGueYVuLuoT4tpTOCLK)

The **CharCodeAt** **Node** outputs the *ASCII* code of a character at a given *index* in a **String**. It takes as inputs a **String** and the *index* of the character whose code is to be obtained, and it ouputs the *ASCII* code of said character.

The characters' *indices* in the **String** start from zero.

If the index given is greater than the **String** length, the output is `-1`.

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