This is a code-driven vehicle framework for Unity, providing modular car logic, wheel and surface interaction, advanced audio systems, and scalable performance tools for custom driving projects.This project is primarily code-based. HDCarController focuses on vehicle physics, driving logic, audio systems, and upgrades, and is largely independent of the render pipeline. The published demo uses URP, but the system also works with HDRP and Built-in. Visual effects and materials may require user adjustment depending on the selected pipeline.Before reading description;You may get the Test Build for windows from this link.Please read carrefully The Dark Side - Theoretical Information for License Agreement and detailed information.You can also find practical setup informaiton inside The White Side - Practical Information document.If you want to get contact with us: msc.hamdi.demirel@gmail.comHD Car Controller is a code-first vehicle controller framework for Unity, built to help developers create believable driving behavior with a clean, modular setup that you can fully customize for your own game. It focuses on vehicle logic, wheel-to-ground interaction, skid and feedback systems, engine audio generation, optional upgrades and NOS configuration, and practical runtime control through dedicated hub prefabs.This package is suitable for multiple genres that involve driving, including racing, open-world driving, simulation, and sim-cade projects. You can tune vehicles from arcade to more realistic handling by adjusting exposed parameters and presets, while keeping a consistent data flow across the entire system.The included content is customizable, but the key point is what the purchase actually provides. This asset includes only the core code and the required runtime hub prefabs (such as TestCar, SkidManager, SharedSingleData, and an example camera setup). Any included 3D models, audio clips, and VFX are provided only as examples for testing and demonstration. They are not production assets and are not the main value of the package. Engine audio libraries, high-quality skid/collision sounds, vehicle bodies, and commercial VFX packs are not included in the price.To use HD Car Controller in a real project, you are expected to bring your own vehicle models, sounds, and effects, then connect them using the provided setup workflow. The included documentation is split into two parts: The Dark Side (Theoretical Information) explains how the systems are structured, while The White Side (Practical Information) shows exactly how to set up the hubs, assign clips, configure surfaces, and troubleshoot common issues.Code-first vehicle controller framework built for flexibility and long-term scalabilityModular runtime hub architecture (vehicle, skid, shared data, audio, camera test setup)Advanced wheel system with per-wheel configuration and independent power, brake, and steering controlColor map–based wheel hit and surface detection for asphalt, terrain, gravel, concrete, grass, and custom surfacesCentralized skid system with camera-aware skid mark rendering and adjustable segment length and lifetimeHigh-performance skid and wheel processing using Unity Jobs and BurstLayered engine audio system using RPM-based audio blocks with dynamic blendingEngine RPM values parsed directly from audio clip names for automatic block setupEngine sound generation using only three AudioSources with smooth transitionsSupport for automatic and manual gear shift sound groupsCamera-based audio perspective system (inside, hood, rear, or custom mixes) without extra codeOptional NOS system with dedicated parameter sets and audio integrationPersistent car upgrade system using JSON-based data storageBuilt-in access to upgrade status and performance values for UI integrationDesigned for racing, open-world driving, simulation, and sim-cade projectsExample assets included for testing only; final visuals and audio are user-defined
