    UnityCar 1.0 Released. The most complete and accurate vehicle simulation on Unity3D

    UnityCar 1.0 Released

    UnityCar is a realistic and complete vehicle simulation package for Unity3D Game Engine. With UnityCar you can easly integrate (without scripting) any kind of vehicle in your game, from a simple city car to a powerful Formula 1, from an offroad to an heavy truck.
    You can obtain any level of simulation accuracy, from an arcade behavior to a almost hardcore simulation.
    Adding a vehicle to your projects is as easy as clicking on a menu voice under Component/Physics menu.

    My package is going to be sold on the Asset Store at 97€. If you are a previous customer the price is 37€.
    While my package is being accepted in the Asset Store, you can buy it via PayPal. Contact me in PM or at info at migliortestesso.com



    In these demos you can test UnityCar with 5 different vehicles (you can select them with PageDown and PageUp keys):

    • Peugeot 205 T16 (a light and fast citycar);
    • Renault Clio Sport (another citycar, a little bigger than the previous);
    • Catamount (a powerful sport car);
    • Gmc Sierra Grande (an offroad car);
    • Monster Truck (an offroad car with very big wheel, perfect to test the Tridimensional Tire feature of UnityCar).


    Features:
    • Very easy to setup just click on "UnityCar" menu voice under Component/Physics menu and you are ready to drive;
    • Realistic tire model based on Pacejka formulas with the addition of longitudinal and lateral relaxation (cause the "shaking" effect of the car after a hard handbreaking, like in the end of this video;
    • Realistic car damages with repair option (based based on the work of BTM)
    • Realistic suspension model with spring, damper (dump and rebound) and anti-roll bar;
    • Optimized code suitable for mobile system like iphone or ipad;
    • Compatible with analogic input like driving wheels and pedals;
    • No lateral sliding on a slope;
    • 3D Tire all the contact points of the tire are found, not just only one vertical, like with the wheelCollider. Can be swithed off for arcade use;
    • Driving Aids useful to obtain an arcade feel (Anti Lock Brackes, Traction Control, Electronic Stability System, steering Assistance, Enanched Grip);
    • Complete DriveTrain modelled with fully functional clutch, differential, engine inertia, transmission (RWD, FWD, AWD), gears;
    • Complete Sound Controller with engine noises, trasmission noise, wind noise, crash noises, skid noise, scrape noise;
    • Customizable Dashboard with TachoMeter, RPMCounter, gear number, ABS, TCS and ESP lights;
    • Brake Lights;
    • Customizable in every aspect of the vehicle:
      • engine power and torque,
      • wheel grip,
      • terrain grip,
      • suspension spring and dampers (dump and rebound),
      • anti-roll bar forces,
      • aerodynamic forces,
      • weight repartition,
      • gears number and ratio,
      • etc

    • 6 fully functional vehicle prefabs included:
      • 1 Off Road car,
      • 2 City cars,
      • 1 Sport Car,
      • 1 Monster Truck car,
      • 1 Empty Car (fully functional car, you just need to place your graphics).

    • Extensive online documentation.


    Plus you get also: 5 fully functional dashboard with graphics, 4 different tyre models and 2 terrains (a city terrain and a track terrain (taken from Unity Car Tutorial)).

    Is this an extension of the Car Physics package that is already on the Asset Store ("EdyVehiclePhysics" or sth.)?

    Btw. I would be interested in a Truck/Heavy Machinery setup.

    Hi azeitler,
    hippocoder is right. Thers no relation between my package and Edy's one. Its a completely different package.

    I'm considering purchasing this script but I have some questions...


    Questions about the purchase:
    - Previous customers have to pay 37€ for this update... if I purchase this update, would I have to pay again for future updates?
    - People who purchases it from the Asset Store will get new updates automatically... how will other people get the new updates?

    Questions about the Controller:
    - Does it include (or would it be easy to include) an accelerometer-controlled car for iOS / Android devices?
    - Does it have an easy-to-implement interface so we can add easily computer-controlled cars or remote-player-controlled cars?

    Questions about aerodynamics components (such as wings):
    - Can we control the position of each wing?
    - Can we change the "angle of attack" of each wing?
    - Do wings produce drag and downforce or only one of them?
    - Are the aerodynamics forces affected by the force and direction of the wind (as they should)?
    - Do we have an easy way to define the air density (it should modify the drag and downforce of the wing... specially during slipstreaming)?

    Other questions:
    - Is there an easy way to define tire wear and/or fuel consumption?
    - Can we use these scripts for 2-wheels vehicles (such as motorbikes)?
    - Can we add/remove weight at certain position of the vehicle?

    For example: when a Formula1 is running out of fuel, its weight decreases and the center of gravity moves forwards. It would be nice being able to tell the vehicle "remove ___ kg at position(x,y,z)" and have the total mass of the vehicle and the center of gravity recalculated automatically...


    Some of these features are fundamental for me and I have partially implemented some of them for another vehicle physics engine... would you accept code submissions? I really need some of those features, but it can be a little difficult to add (and maintain) new features if you update the code frequently and there isn't an easy way to merge my code with yours...

    are you aware of the prices of other similar products? for example madcar 3 (vehicle physic engine plugin for 3dStudio, 200€) or car-x (vehicle physic middleware for game engines, standard license cost starts from $19500)? not to mention simvex..

    1. no you are not going to pay
    2. with direct access to my FTP server

    1. a previous customer did it easily. im going to deepen this question
    2. the only needed inputs for the car to be computer-controlled cars or remote-player-controlled are throttle and brakes (vertical axes) and steering (horizontal axes). All these variables are exposed.

    1. yes (every wing is a gameobject)
    2. yes
    3. wings produce downforce, if you want to use drag effects too you can increase the cx value of AerodynamicResistance class
    3. at the moment no
    4. yes (air density is defined as a variable)

    1. at the moment no (im evaluating a way to implement this)
    2. planned in the next update
    3. you can remove weight only if you have previously added. so if you want to simulate decreasing weight tank, you should first add a weight with all the fuel you want (adding a gameobject with a boxcollider, a rigidbody and a fixed joint with the parent rigidbody) in the right position, and the during runtime lower the tank's rigidbody weight conveniently.

    Really awesome work. Definanetly feels on par to me with alot of major commercial products.

    If I had a use for this I'd definanetly purchase this.

    The only thing that I worry about is that too many people will purchase this and too many unity games will have the same feel on their vehicles...

    Good work. Although I would probably have purchased it if it had built in AI/Pathfinding/Waypoints for AI cars too.

    I am a previous customer but I didn't have enough time to develop a racing game until now... and you have released a new version of your script just when I have started to work in my prototype, so I wanted to be sure if this new update will include several features I will need for my game (as you can guess, the most important part for me is aerodynamics).

    Quote Originally Posted by NewLife View Post

    I'm not completely sure, but I think it is different to apply the drag in the wing position than applying the drag in the center of mass. Even if the drag amount is the same in both cases, it would affect to the understeering / oversteering behaviour of the vehicle.

    The effect of the wind at the longitudinal axis is really easy to implement... instead of using the car speed to calculate the aerodynamic forces, you should use (car speed - wind speed):

    - If there isn't any wind, we only take into account the car speed to calculate the aerodynamic forces.
    - If the wind moves in the same direction than the car, the wind reduces the aerodynamic forces caused by the car speed.
    - If the wind moves in the opposite direction than the car, the wind increases the aerodynamic forces caused by the car speed.

    However, the aerodynamic effect of lateral winds are more difficult to calculate...

    So any rigidbody that I "attach" to the vehicle using some kind of join would be taken into account to calculate the weight and center of gravity of the vehicle automatically?

    Well, you have already implemented (or your are planning to implement) most of features I need... In any case, I'll write you an email to purchase this update and talking about these topics.

    eh eh eh i didnt think about this eventuality..
    Anyway its very easy to change drastically the feel of the vehicles by changing the engine response (changing the torque curve) and the tire response (changing the tire parameters).
    Btw thank you for your appreciation.
