How to build a Game with Unreal Engine
In this guide we will walk you through how to integrate Embedded Wallet features using Sequence's Unreal SDK. Checkout the Boilerplate for this guide.

1. Setup
Installation
To get started, download the latest version
of the Sequence SDK and put the SequencePlugin folder into your Unreal project's Plugin folder.
Alternatively, learn how to get the SDK from the Epic Games Marketplace.
Configure your Project
Now create the SequenceConfig.ini file, based on this format, in your project's Config/ directory and include the
WaaS- and Project Key from the Sequence Builder. Generate a 32-character encryption key. This key will be used to securely store your user credentials.
The remaining values can be filled in later or whenever new authentication options are needed.
Include the Built-In UI
Let's build on top of the Pawn BP_CustomSpectatorPawn and GameMode GM_Sequence included with the SDK by duplicating them into our project.
This will allow us to customize them as needed.
We recommend using the Built-In UI for development purposes, learn how to create your own UI.
2. Interact with the SDK
To enable interaction with the Sequence SDK, start by creating a widget blueprint for your project.
Open the Sequence Pawn, locate the Auth Success event, and create a reference of your new UserWidget.
Finally, use our subsystems like the SequenceWalletBP to access our features from the following sections.
3. Display Wallet Information
To display the wallet's address and balance, first retrieve the user's wallet reference. Then, use it to fetch and display the wallet's address and current balance directly from the connected blockchain.
Example Use Case:
Build a UserWidget for your users Web3 profile.
4. Sign a Message
To sign a message, first retrieve the user's wallet reference. Then, use the input message from the boilerplate and initiate the signing process through the wallet to generate the signature.
Example Use Case:
You can use this feature to sign a message from your backend, allowing you to verify your user's wallet upon receipt.
5. Send Ether to another User
To send an Ether transaction, use the recipient's address and amount from the boilerplate's input fields to initiate
the transaction with the SequenceWalletBP subsystem and listen to the response event.
Example Use Case:
A user initiates a payment transaction to another user within your game client.
