🔊 Vehicle Horn – Modular Horn Audio System for Unity

Vehicle Horn is a lightweight and reusable horn playback system designed primarily for vehicle-based games and simulations.

It provides a clean and modular way to handle horn audio playback with configurable minimum horn duration, helping prevent short audio flickers and unnatural playback behavior.

Built with a reusable package-based architecture, Vehicle Horn is easy to integrate into existing gameplay systems while remaining fully independent from vehicle physics or controller implementations.

🚀 Key Features

🔊 Controlled Horn Playback

• Configurable horn audio clips
• Minimum horn playback duration
• Prevents rapid horn flickering
• Stable start/stop behavior

⚡ Lightweight & Efficient

• Minimal runtime overhead
• Coroutine-based timing system
• Cached WaitForSeconds usage
• No unnecessary update loops

🧩 Modular Architecture

• Reusable package-based structure
• Independent from vehicle controllers
• Easy to integrate into existing systems
• Clean separation between runtime logic and demo content

🎯 Simple Runtime API

• Play and stop horns through a dedicated system
• Centralized horn management
• Safe runtime state handling

🚗 Vehicle & Non-Vehicle Usage

Designed for:

• Cars
• Trucks
• Traffic systems
• AI vehicles
• Driving simulators
• Arcade games
• Any gameplay system requiring horn audio

The horn system can also be used completely independently from vehicles.

🎨 Configurable Horn Presets

Create reusable horn configurations with:

• Custom horn audio clips
• Adjustable minimum playback duration

📦 What’s Included

• Vehicle Horn runtime system
• HornConfiguration asset system
• Ready-to-use demo scenes
• Standalone horn demo
• Car presentation demo
• Documentation and setup guides
• Video tutorials

🚗 Car Demo Included

A vehicle presentation demo is included to showcase horn usage in a driving environment.

The horn system itself is fully independent from the vehicle controller and can be used separately without any car setup.

The car demo is built using the SMVC (Simple Modular Vehicle Controller) framework.

🧠 Designed for Flexibility

The system is intentionally decoupled from gameplay logic.

It does NOT implement:

• Vehicle physics
• Engine simulation
• Traffic AI
• Input systems

Instead, it focuses entirely on:

• Horn playback
• Playback timing
• Runtime horn state management

This makes integration simple and flexible across many project types.

🎨 Render Pipeline Support

• Built-In Render Pipeline (BRP) – ready to use
• Universal Render Pipeline (URP) – supported via included package
• High Definition Render Pipeline (HDRP) – supported via included package

⚙️ Easy Setup

1. Create a HornConfiguration asset
2. Assign an AudioSource
3. Add the Horn component
4. Call Play/Stop through the API

The system is designed to be simple to integrate while remaining extensible.
