# Unreal Engine Integration

## HTTP Requests

There are several options in Unreal Engine for making HTTP requests depending on your needs.

### [web3.unreal](https://github.com/G7DAO/web3.unreal) (Recommended)

We have built a free and open source plugin specifically for Unreal devs that wraps the UE HTTP runtime. 

This plugin exposes async nodes globally that parse input and output parameters into HyperPlay calls. This way you can work in an Unreal context without having to worry about formatting or syntax errors. 

See our API docs for examples you can easily copy and paste into your Blueprint graphs.

### C++ 

You can use the [Unreal Engine HTTP runtime](https://docs.unrealengine.com/4.27/en-US/API/Runtime/HTTP/) directly. See our API docs for examples.

### Fetch Plugin

This plugin makes generic HTTP calls at the blueprint level easy.

A license can be [purchased in the Unreal Marketplace](https://www.unrealengine.com/marketplace/en-US/product/fetch-a-simple-http-client?sessionInvalidated=true) for commercial projects.

Or [downloaded from the Github repo ](https://github.com/GDi4K/unreal-fetch)for non-commercial projects. 

## Architecture

### Blueprint Library

If you intend on using the UE HTTP runtime directly, it is recommended that you expose these functions in a Blueprint Function Library.

### Game instance

Common HyperPlay API calls can be defined in your Game Instance class. This is a good place since it is available globally, only exists on the client side, and persists despite level changes and other changes to game state.

# Agent Instructions: 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:

```
GET https://docs.hyperplay.xyz/developer-docs/design-considerations/unreal-engine-integration.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
