Vehicle Controller 2D: Car & Bike Physics

Vehicle Controller 2D is a complete kit for side-scrolling, hill-climb style driving games. It comes with physics-based cars, bikes, trucks and tanks, the systems that make them feel alive, and six ready-to-play demo scenes. Drop in a prefab and drive, or turn your own sprites into a working vehicle in minutes with the Vehicle Setup Wizard.

Vehicles

• 6 ready vehicles: dirt bike, jeep, sports car, six-wheel truck, tank and a pedal bicycle
• Wheel-joint physics with suspension, air control, rider leaning, handbrake and nitro
• Engine model with torque curve, gears, automatic or manual gearbox, rev limiter and RPM-blended engine sounds
• Tank tracks that wrap around the road wheels and follow the suspension
• Ragdoll driver with adjustable rider pose

Gameplay

• Health and crash damage, fuel and fuel pickups
• Stunt detection: flips, wheelies, stoppies, air time and perfect landings
• Garage with upgradable parts, coins, saving and a free-tuning developer mode
• Trailers and cargo with delivery zones
• Rope bridges, seesaws, boost pads and breakable crates, with object pooling
• AI drivers that read the terrain, a race tracker, and ghost replays of your best run

World

• Surfaces: mud, sand, snow, ice and floating water, each with its own grip, particles and sounds
• Deformable ground: wheels press ruts into mud, sand and snow, and spinning wheels dig deeper
• Endless terrain generator with seeded hills that get harder with distance (standalone, usable in other projects)

Controls, UI and Cameras

• Keyboard, gamepad, touch buttons and tilt, with rebindable controls
• Local split-screen for two players
• HUD with health, fuel and speed bars, a stunt log and a speedometer that fits each vehicle
• Built-in follow camera, plus Cinemachine 2.x and 3.x support

Editor Tools

• Vehicle Setup Wizard (Tools > Cubehole > Vehicle Setup Wizard): pick a vehicle type, drop in a body and wheel sprite, and get a drivable prefab
• Starter shapes and handling presets for quick prototyping

Demo Scenes
Demo, Surface, Endless, Delivery, Race and Split-Screen.

Requirements

• Unity 2022.3 LTS or Unity 6 (compiles without warnings on both)
• Built-in Render Pipeline or URP
• Works with both the old Input Manager and the Input System
• TextMesh Pro (Unity asks to import its Essentials on first use)

Optional packages (detected automatically when installed)

• Cinemachine 2.x / 3.x: Cinemachine follow camera
• Input System: gamepads, tilt, rebinding
• Universal RP (2D Renderer): headlights and nitro glow with 2D lights
• 2D SpriteShape: SpriteShape skin for the endless terrain

Clean, documented C# in its own namespace and assemblies, with a 46-page PDF user guide and scripting reference.
