# OverScript

### Description

In order to use the [OverGraph](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overgraph.md), you need to assign an [OverScript](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md) to a GameObject and assign the GameObject to the OverGraph.

The purpose of an [OverScript](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md) is to provide a bridge between the logic, described by the [OverGraph](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overgraph.md), and Unity itself, which is responsible for compiling and executing it.

To add an [OverScript](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md) to the project, simply create a new GameObject and add a new [OverScript](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md) Component to it.

To add an [OverGraph](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overgraph.md) to this script, the User can either create a new [OverGraph](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overgraph.md) and drag and drop it in the OverGraph field, or by pressing the Create New Script button. This will automatically create and assign a new [OverGraph](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overgraph.md).

An integral component of the script management system is the [OverScriptManager](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscriptmanager.md), which needs to be added in the Scene in order to unlock all the features of the scripting system.

Each [OverScript](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md) contains a list of local variables. Local means that only this specific script can access and edit them.

For global variables, i.e. variables shared between [OverScripts](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md), these must be entered within the OverScript Manager

Once a variable is defined, it can be directly added to the Graph as a Node and used in Visual Scripting.

{% hint style="info" %}
**Note**: in order for the [OverScript ](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md)to work properly in app, it needs to be a child of an [OvrAsset](/over-sdk-manual/sdk-window/over_asset.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.overthereality.ai/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overscript.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
