Realistic Steering Wheel Control – Mobile Touch Input

Realistic Steering Wheel Control is a realistic, responsive, and highly customizable UI input system designed for mobile and touch-based applications.

It simulates a real steering wheel by converting drag-based rotation into smooth, normalized input, making it ideal for driving games, simulations, and any system that requires rotational control.

Key Features:
- Realistic drag-based steering input
- Smooth and organic rotation behavior
- Normalized output (-1 to 1)
- Adjustable sensitivity and maximum steering angle
- Configurable dead zone with flexible behavior
- Optional automatic centering (auto-reset)
- Event-driven input system
- Multiple steering wheel visual styles included
- Lightweight and high-performance implementation

Steering Wheel Variants:
The asset includes multiple ready-to-use steering wheel prefabs:
- Realistic steering wheel
- Icon-style steering wheel
- Outline-style steering wheel

Each variant uses the same core logic, allowing you to:
- Quickly prototype different visual styles
- Swap visuals without changing functionality
- Customize or replace sprites to fit your project

Car Demo Included:
A complete car demo is included to showcase real-world usage. It demonstrates how to connect the steering wheel input to a vehicle controller using a modular architecture. The demo supports multiple render pipelines: Built-In Render Pipeline (BRP), Universal Render Pipeline (URP), and High Definition Render Pipeline (HDRP). This ensures compatibility across different project setups.

Flexible Input System:
The steering wheel outputs a normalized float value (-1 to 1), which can be used for vehicle steering, character rotation, camera control, UI interactions, and any custom gameplay system requiring rotational input. You can subscribe to events (OnInputChanged) or poll input manually via API.

Customization:
The system is designed to be highly configurable:
- Sensitivity controls responsiveness
- Max Angle defines rotation range
- Dead Zone stabilizes input near center
- Subtract Dead Zone smooths transitions
- Auto Reset returns wheel to neutral
- Reset Speed controls centering speed

This allows you to fine-tune the control for arcade, simulation, or hybrid experiences.

Important - Pivot Setup:
Correct pivot placement is essential for proper behavior. The steering wheel must rotate around its visual center, controlled by the RectTransform pivot. Included prefabs may use custom pivot values (not always 0.5, 0.5), which is intentional for non-perfectly round steering wheel visuals. If you replace the sprite, especially with a perfectly round image, you may need to adjust the pivot. Incorrect pivot setup can result in off-center rotation and unnatural steering behavior. Always verify pivot alignment when customizing visuals.

Performance:
- No runtime allocations
- Minimal computations per frame
- Efficient input processing
- Suitable for real-time applications on mobile and desktop

The system is designed to be lightweight and scalable.

No External Dependencies:
- No external APIs are used
- No API keys are required
- Fully offline and self-contained

Architecture:
The asset follows a modular package-based structure with core logic separated into reusable packages, designed for integration into larger systems and easy to extend and maintain.

Use Cases:
- Driving games
- Racing games
- Vehicle simulations
- Mobile control systems
- Any rotational input-based gameplay
