# CharCodeAt

## Overview

![The CharCodeAt Node.](https://926825830-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FKQhJdUBr7YQzfIwmpAZ9%2Fuploads%2Fgit-blob-ec41585b23efc5277234a4b8ad76d6be87dae805%2Fcharcodeatnode.png?alt=media)

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**](https://docs.incari.com/incari-studio/2022.1/overview#scopes): **Project**, **Scene**, **Function**, **Prefab**.
