Summary of Changes

Hello @RKS13D, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new Unreal Engine project, 'TrivialKart_Unreal', designed to showcase the integration of Google Play Services. It lays the groundwork for a kart racing game, complete with core gameplay mechanics like movement, fuel management, and distance tracking, alongside a comprehensive user interface for interacting with game features and the Google Play ecosystem. The changes encompass project configuration, C++ gameplay logic, and UI elements, all aimed at demonstrating a functional mobile game with modern platform service integration.

Highlights

• Unreal Engine Project Setup: A new Unreal Engine project named 'TrivialKart_Unreal' has been initialized, including standard .gitattributes for LFS tracking of large assets and a comprehensive .gitignore for common Unreal build artifacts.
• Google Play Services Integration: The project is configured to integrate with Google Play Services, enabling features such as Google Play Games Authentication, Achievements, and In-App Purchases (Google IAP). This includes specific settings in DefaultEngine.ini and C++ logic in the game instance.
• Core Game Logic and UI: Fundamental game mechanics like player movement (KartPawn), fuel consumption, distance tracking, and associated achievements are implemented. A robust UI system (TrivialKartHUD, PlayBoardWidget, GarageWidget, PGSWidget, StoreWidget) is established for in-game navigation, displaying player stats, and interacting with Google Play Services and the in-game store.
• Enhanced Input System: The input system has been updated to use Unreal Engine's Enhanced Input, with new axis configurations for various gamepads and VR controllers, ensuring broader compatibility.
• Asset Inclusion: Numerous new assets, including sprites, textures, tile sets for backgrounds, car models, fonts, and UI elements, have been added to populate the game world and user interface.

Code Review

This pull request introduces the 'Trivialkart' Unreal Engine sample project, demonstrating integration with Google Play services for features like authentication, achievements, and in-app purchases. The changes are extensive, covering project setup, configuration, C++ game logic, and UI widgets. My review has identified a critical security vulnerability due to a hardcoded password in a configuration file, which must be addressed immediately. Additionally, there are several high-severity bugs in the game logic, particularly concerning frame-rate dependent calculations and incorrect API usage that could lead to unexpected behavior. I have also noted several medium-severity issues related to code maintainability, configuration redundancy, and potential memory leaks. The provided feedback and code suggestions aim to resolve these issues and improve the overall quality and security of the project.

Looks good, please add copyright to the files, I think this how to do in Unreal ==> // Fill out your copyright notice in the Description page of Project Settings.

If some of the C++ files are autogenerated during build, not sure we need to add them to source control
