    AWS GameKit Plugin for Unreal

    AWS GameKit Plugin for Unreal

    The AWS GameKit Plugin for Unreal

    AWS GameKit is an open-source engine integration toolkit for game developers who want to create high-quality, cloud-connected game features without the potentially steep learning curve for cloud service architecture and AWS. With AWS GameKit, you can deliver core functionality to your players with minimal effort and time by using pre-built AWS solutions for your game backend and integrating the features into your game. You can use the AWS GameKit game features as designed or as a launch pad to expand and customize as needed. The plugin is developed using Unreal version 4.27. Install before proceeding. Game projects created in Unreal versions later than 4.27 are not backward compatible. AWS GameKit supports Unreal Engine version 4.27. Create the Visual Studio Solution for your game. Build GameKit C++ and copy over the DLL/PDB files. Make sure to checkout the matching version from the .gkcpp_version file in this repository.

    Graph NotebookAmazon GameLift Unity

    Graph NotebookAmazon GameLift Unity

    Access GameLift resources and integrate GameLift into your Unity game

    The Amazon GameLift Plugin for Unity contains libraries and native UI that makes it easier to access GameLift resources and integrate GameLift into your Unity game. You can use the GameLift Unity Plugin to access GameLift APIs and deploy AWS CloudFormation templates for common gaming scenarios. Auth Only, this scenario creates a game backend service that performs only player authentication and no game server capability. It creates a Cognito user pool to store player authentication information, as well as an API gateway REST endpoint backed up AWS Lambda handlers to start a game and view game connection information. The Lambda handler always returns a 501 Error (Unimplemented). Single-Region Fleet, this scenario creates a game backend service with a single GameLift fleet. After player authenticates and starts a game (with a POST request to /start_game), a AWS Lambda handler searches for an existing viable game session with an open player slot on the fleet.

    ArchiSteamFarm

    ArchiSteamFarm

    A multi-account able app for farming cards in Steam

    ASF is a robust C# application designed to farm Steam cards from multiple accounts simultaneously. Unlike other tools like Idle Master, which manage only one account at a time and require the Steam client to be running, ASF operates without the Steam client or additional processes. This allows users to farm Steam cards from unlimited accounts efficiently. ASF is optimized for use on servers or headless machines and supports all major operating systems, including Windows, Linux, and macOS, through the .NET Core runtime. This cross-platform compatibility makes ASF a versatile solution for Steam card farming in various environments. In addition to card farming, ASF includes features like serving as a Steam authenticator and chat logger. It also supports a plugin system that allows users to extend its functionality. Whether you need to automate card collection, manage Steam accounts, or customize features, ASF provides the flexibility and power to meet your needs.
