I designed and developed this 3D Oil Tanker Truck Simulator using Unity Engine and C#, taking full responsibility for the project from initial concept through to final implementation. This game was created to provide a realistic and immersive heavy vehicle transport simulation for mobile platforms, where I managed all aspects of development, including tanker driving mechanics, fuel transport systems, mission-based objectives, level and environment design, UI/UX implementation, dynamic scenario creation, and performance optimization. I developed highly realistic truck controls featuring smooth steering, precise acceleration and braking, and advanced physics tailored specifically for heavy oil tankers, ensuring that the transport of fuel across challenging routes required careful control, skill, and balance. The gameplay features a fuel delivery system where players must transport oil safely across complex road networks while maintaining stability and avoiding accidents, creating a high-stakes and engaging driving experience. I created detailed and immersive environments, including mountain roads, sharp turns, natural landscapes, bridges, and urban traffic elements, designed to challenge players’ driving skills and enhance realism. Dynamic driving scenarios such as uphill climbs, curved roads, narrow paths, and obstacle-based routes were implemented to increase difficulty and provide a variety of gameplay challenges. I also developed a clean and responsive UI system, including interactive menus, mission indicators, in-game dashboards, and controls optimized for mobile devices, ensuring players could navigate the game intuitively while focusing on precise driving. Performance optimization was a key focus, achieved through efficient asset management, optimized lighting and textures, modular C# scripting, and physics tuning, delivering smooth gameplay and stable frame rates across different mobile devices without compromising visual fidelity. This project showcases my comprehensive expertise in Unity 3D game development, vehicle and tanker simulation mechanics, transport mission systems, immersive environment design, dynamic scenario creation, UI/UX implementation, and mobile game optimization, highlighting my ability to create polished, engaging, and professional-grade simulation games that combine realistic driving, high-quality visuals, and stable performance into a complete, market-ready experience.
