🚗 Car Controller for Unity – Build Driving Games Faster

Creating a functional and enjoyable car controller in Unity is one of the most common challenges faced by beginner and intermediate game developers. WheelColliders, physics tuning, steering responsiveness, braking balance, and audio synchronization can easily become overwhelming. Many developers abandon vehicle-based projects simply because setting up a reliable controller takes too much time.

The Car Controller for Unity asset pack is built to solve exactly that problem. It provides a clean, beginner-friendly, and production-ready driving system that allows you to start building car-based games immediately—without fighting Unity’s physics system.

This asset is suitable for driving simulators, racing games, open-world exploration projects, prototypes, and game jams.


💰 Pricing & License Information

  • Price: $9.99 USD or more
  • License: Personal and commercial use allowed
  • Refund Policy: ⚠️ No refunds due to the digital nature of the product

Once purchased, you can freely use this controller in both personal and commercial Unity projects.


📦 What’s Included in the Asset Pack

1️⃣ Custom Car Controller Script

At the core of the package is a fully customizable C# car controller script designed with clarity and performance in mind.

Key features include:

  • Acceleration, braking, and steering logic
  • Adjustable motor force, brake force, and steering angles
  • Smooth and predictable vehicle handling
  • Dynamic audio pitch control based on speed
  • Single optimized AudioSource handling both engine and brake sounds

The script is cleanly written and well-structured, making it easy to modify, extend, or learn from—perfect for beginners who want to understand how vehicle controllers actually work.


2️⃣ Prebuilt Car Prefab

To save you hours of setup time, the package includes a ready-to-use car prefab with:

  • Properly configured WheelColliders
  • Rigidbody settings optimized for vehicle physics
  • Audio and input already wired up

Simply drop the prefab into your scene, press Play, and start driving.


3️⃣ Demo Scene

The included demo scene allows you to:

  • Test the controller instantly
  • Fine-tune physics values
  • Observe steering, braking, and suspension behavior in real time

This is especially useful for understanding how small adjustments affect vehicle handling.


4️⃣ Free Car Model from Unity Asset Store

A free car model sourced from the Unity Asset Store is included to help you get started visually.

  • Safe for both personal and commercial use
  • Properly credited under a license that allows redistribution within this package

You can replace the model at any time with your own vehicle assets.


5️⃣ Documentation Included

Clear documentation is provided to guide you through:

  • Initial setup
  • Script configuration
  • WheelCollider tuning
  • Audio replacement
  • Common issues and fixes

The documentation is written in simple language, making it accessible even if you are new to Unity vehicle systems.


🔊 Audio System Explained

The car controller includes engine and brake sound support implemented using a single AudioSource for optimal performance.

You can:

  • Assign your own engine sound clips
  • Replace brake sounds easily
  • Adjust pitch scaling to match vehicle speed

⚠️ Important Notes & Troubleshooting

  • If wheels float or sink into the ground, ensure your terrain has a proper collider and adjust WheelCollider suspension values.
  • Audio clips can be swapped at any time without modifying the script.
  • Rigidbody mass and drag values can be tuned to match arcade or simulation-style driving.
