# How Do Blueprints Work?

In their basic form, Blueprints are **visually scripted** additions to your game. By connecting **Nodes, Events, Functions,** and **Variables** with Wires, it is possible to create complex gameplay elements.

Blueprints work by using graphs of Nodes for various purposes - **object construction**, **individual functions**, and general **gameplay events** - that are specific to each instance of the Blueprint in order to implement behavior and other functionality.

Let's look at each of these use cases by an example.

## 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://www.xrdev.app/mixed-reality-docs/mixed-reality-using-unreal-engine/blueprints/concepts/how-do-blueprints-work.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.
