In this video, you will learn how to structure your hierarchy to meet the WheelCollider demands. You're going to write code that allows you to easily drive a vehicle around within your Unity3D scene, and if you want to go the extra mile, hang around for a few extra minutes to code up the camera controller that follows the vehicle from behind while you drive.
This tutorial is the best of all the tutorials I've watched on this subject. Excellent microphone quality, minimal editing, clear speaking, clear explanations, and very quick!

After 3 years your tutorial is still amazing
Helpful af to me multiple times. Mainly the placement of the wheel colliders and the excellent settings to 'tune' them.
this was excellent. video was long, so i was expecting a lot of time wasting, but there really wasn't any. straight to the point and easy to follow.
This is the best tutorial here. Everything in the script is so neatly orchestrated this just works! Much thanks!
Great tutorial, I especially love the camera code. I was having a lot of jitter following a rigidbody but your code smooths it all out.
this is so long ago but in case other people see, you need to rename the Update() as LateUpdate() or even FixedUpdate() and retry. Should remove the stutter.
As others have pointed out, best tutorial in the subject. I manage to easily adapt a Cinemachine camera to the setup and it's working smoothly. Thanks a lot!
Even after few years this tutorial is very useful for me. Great job.
I used a different car from the asset store, and it accelerated extremely slowly. I had to decrease mass value for the whole car, increase the wheel collider radius (so that it collided with the ground) and increase motor torque to a lot more, and also changed friction values slightly. Just in case anyone faces the same problem.
Anyway, great tutorial, it was very clear and easy to follow. I will check your channel for more! Thank you.
thanks a lot *____*
WIWOSEOAW48PS I know it’s late but if you scaled game object with the driving script attached to it you would change the physics I think.
@@lemonface2938 yeah u r correct. It changes the physx. I experienced that bug.
@@lemonface2938 thanks
Bro, I'm not even kidding. Thanks to your comment, I solve a problem that involved hours of research. I forgot to increase the collider radius...
One of the most useful tutorial so far!
It helps with my graduation project a lot.Thanks
best tutorial for wheel colliders, physics working fine
I got way more out of this than I expected to.
Instant sub, thanks so much!
Thank you thank you thank you! I've been struggling through the wheel collider tutorial on Unity's site for two days. The tip you had about adding an additional Box Collider to the root car node (around 9:00) was the trick that fixed my crazy bouncing car!
Hello, I did the same as mentioned in the tutorial still my car is bouncing. Can you help?
@@AllFather414 same with me . help please
for me, i forgot to increase the mass from one to something higher
I know im late to the party but ive spent a long time and a lot of tutorials deep to get these Wheel colliders working bug free - this is the first tutorial to do that thanks for the Video homie.
Great Tutorial ! Very clear & clean coding!👍
First time seeing your channel. Instant subscribe. Thanks for the great tutorial!
It is really a great, wonderful, excellent work. Thank you so much. Keep on coding!
If you want to make aligning anything much easier, use the isometric view by clicking on the small white cube in the middle of the xyz selector found in the upper right of your Scene tab window.
In case your car moves too slowly when accelerating: Try scaling your model (ALL parts of the car + colliders etc) downwards. I somehow assume that the "unity physics system" takes the model size - relative to the world grid size - into consideration when applying physics to it.
Somewhere I read, that the grid squares (the smallest one if you zoom in) represent "1 meter". Originally my model was about 8 meters long and accelerated horribly slow. I scaled it from (1,1,1) to (0.2,0.2,0.2) and that did the trick.
Correct, a transform gap of 1 is one meter, and this is linked to the physics notion of a Newton (1kg * meter * meter / second * second). So size does matter when if comes to physics-driven acceleration in Unity.
Won't the car look too small compared to other objects? Or is there something I am not getting...?
The car shouldn't look smaller, if you scale all of your other world objects (houses, trees, etc) to the same relative size (like in the real world). Maybe my applied scale (0.2) was too small. I haven't done a lot of experiments with it, but I think you should still be able to have larger cars (8m). Maybe the mass was too big for the adjusted torque of the wheel colliders.
Try therefore different values for the mass of the car or wheel collider properties (torque, stiffness, etc) to get the driving behavior you wish.
Another thing I learned in UE4 (but can't remember if it is present in Unity) was friction between ground and wheels. This kind of parameter plays an important role for acceleration and steering too.
@@simonmathis5318 thank you, I will look into those. Won't, lowering the friction, make it look like the car is skating on ice?
@@RobertoOrtis Yes, this is exactly going to happen, if you set the fricition too low. Setting the friction too high may get you an unrealistically stable car. But in the end, it all depends on how you want the car to behave in your game.
I come here because I want to know how carting microgame template in Unity work. And this tutorial is very help full. Your tutorial is very good and straightforward. From now on, will be your subscriber ^_^

Great video! It was easy to understand, liked and subscribed!
That was beautiful. You made a legitimate baby out of that code, and all I have left to say is: Mazel Tov!
I done everything as Tutorial but car moving very slow when Accelerating+Steering. What can be the reason? I even using same Low Poly Destructible Car. Is unity physics changed in 3 years? Please reply.
So hard find good videos, thanks hope you will make more video that continues with this car physics.
One of the best unity tutorials I've come across! Subscribed!
im really happy for you.
This has been incredibly helpful! Thanks!!!
Can you help me

Thank's This Tutorial, Was "VERY USEFUL"....
50 motor force is low for 1500 mass. I followed tutorial and put 300 for motor force.
Its working perfectly. Thank you so much.
Now, I can make a race game against asphalt :)))
this is exactly what I needed
Can you do a follow up video for handling different road surfaces. Asphalt vs dirt for example.
I think, you need to add triggers on road, and change wheelcollider friction's settings when you in trigger. That easy
@@sweftis8300 physic materials. ;)
@@sweftis8300 or add different friction for the ground and keep the wheel friction static
@@bartwestenenk6088 that doesn't work that good... Just change the wheellcollider sideways slip and forward slip based on the ground physics material. RCC for example does that'
For those whose car is not moving...
I was able to solve this by tweaking the wheel collider's radius (.6 in my case) and changing the motor force (1000 in my case) or resizing the object to a smaller size.
hell yeah exactly what I needed thank you(:
Noice,
My car was bouncing around but I forgot to add more weight and it fixed it all
Awesome tutorial man!
you actually did this really good amazing thank you you are a cool dude
Thanks for this perfect tutorial.
Thanks for teaching us 👍🏼😎
Fixed update should be used for physical Calculations and Update for Input/Output. Update is called every frame, FixedUpdate is called 30 or 60 times per second.
Thank you very much. No words to say.
Best tutorial very easy to follow good guidance.
Thanks for the feedback!
regarding FixedUpdate and LateUpdate... Basically before Update is ran there is a before and after update method that you can use for physics (before) and camera (after) respectively most commonly which can fix stutter for the camera when all other object movement is already processed for example... this was mentioned in one of the tutorials
thanks for teaching,you are good teacher
I had an issue with the tire geometry clipping through the floor and it took me a little too long to realize the wheel collider's radius should NOT be .08 like mentioned in the video. I used .25 scale, just like you said but the wheel radius was way too small and should actually be 0.34
Excellent tutorial!
Best on ever i watched
Very nice tut
If anyone of you have been stuck with the movement, just make sure the car's collider is above the wheel's collider. I don't know if I didn't pay attention but I got stuck on it for 2 days. Thanks for the tutorial. Loved it.
it doesn't work for me
@@CurioseaTodo Is the car not moving?
@@lucidjuice101 now works, thanks
@@CurioseaTodo Cool, welcome
Thanks a Ton Brother it worked :)
If your car doesn't move or move too slow, try to make the car smaller, it worked for me. And thanks for the tutorial
Best tutorial ever!
So, when I drop my vehicle, the wheel colliders stop at the ground plane, but the meshes pass through for about three to five frames. It's barely noticeable, but we can't exactly have wheels passing through solid objects, lol. Any ideas? I'm almost tempted to just program my own wheel colliders.
would it be smart to use an array for the wheel colliders? This way it's all in one variable? Just curious.
your naming skills are awful xD
but the tutorial is one of the best I've ever seen... good job man
Thank you for what you are doing.
Hello!
This tutorial is amazing and it's really helpful, but i have a question.
How can I make for example a wheelhub that positions and steers with the wheels, but it doesn't rotating?
Awesome Job bro!!!!
Literally the first useful video I've found on wheel colliders.
I do have one issue, everything works fine but the car doesn't move (the wheels turn and rotate, there are no errors) the car just doesn't move :c
I have the same problem, has anyone figured out why?
is the updateWheelPoses() to just update the visuals or to actually drive the car? Will it also drive without that function if I don't want to update any visuals?
hey. Thanks for the video. I have the problem that when I stop the car, it still moves around. Set motor torque to 0 and added a brakeforce. The wheels don't move, but the vehicle is sliding around on the plane.
Do you have a soluition for that?
Amazing man
Love You Bro
when I press play my car starts breakdancing for some reason, dunno how to fix it
Can anybody tell me if in making turns (in this tutorial script) is involved any friction force or this turns are just made by calculating the position of the wheels and the input from the arrows?
awesome tutorial
excelente, muchas gracias!
You saved me.
Thank you...!
Great tutorial.
My car is flipping every time i turn left or right.How can i solve the problem?
It's work.. but why my car's wheel(mesh wheel) goes crazy when I on the player mode? Help plss
can i use this for my game project? and how to use this as mobile inputs like steering wheel and acel&break buttons ?
Hi, I wrote a code similar to this but when I run the car start moving backward without any input, I tried several ways but the only thing has changed is the direction of the initial movement, I mean the car starts going forward initial after runic the fame. Does anyone have any idea in this case?
If I dont make the motorForce= 5000, my car is driving very very slowly. What is the reason of this?
The only issue ive been having is that when i hit play the wheel colliders are bouncing like crazy/stuttering on a flat surface as if they were on an extremely bumpy road. so far I've had no luck figuring out why.
Muito obrigado pelo tutorial, me ajudou muito. Sucessos na sua vida!!!!
I am using another car but when I click on play button it just floats I added rigid body with 1500 mass but it still floats and keeps moving in random direction somebody help
vre poutana how is the car moving ??? ytou didnt apply any modifications to transform. only to wheel coliders and their graphics
I've tried to combine this tutorial with my logitech G29. It worked pretty good just one thing when I fully press down my accelerate paddle, my camera jitters. (I've added my camera as a child to the car for now.)
works perfectly !
Hey i have my car up and ready but the wheels clip through the ground did i miss something? i have wheel colliders
I have a problem, wheels is spining but car is not stuck and i dont know what to do
Thankyou so much
Can we stop the car immediately after releasing input?
Does anyone know a way to enter the car if you are using a first or third person controller?
Hey good job, but i''m running into a problem here ...
while the left side of mt car is working awesome my right side front and back wheels are turned inside out and the only way to disable that from happening is...
private void UpdateWheelPoses()
{
UpdateWheelPose(frontLW, frontLWT);
//UpdateWheelPose(frontRW, frontRWT);
UpdateWheelPose(rearLW, rearLWT);
//UpdateWheelPose(rearRW, rearRWT);
}
But then again they look ok but do not spin any suggestions?
is this car have break function ?
im sorry if i not recognize ..
for some reason when I try the wheel colliders out they instantly fall off the vehicle and go forward hundreds of blocks at a constant speed
any ideas of how to fix?
I'm getting a Syntax error the way the camera script is currently written, error CS1003. Any ideas? (total newb)
Great Tutorial but I have this issue.
I applied Wheel Colliders to my Wheels and everything "technically" works. Problem is that when Play is hit, all 4 wheels flip sideways.
Any thoughts as to why that might be or - if not - how I could patch something like that?
U have the cheat code activated that makes the wheels go sideways thus allowing you to run it on water like in GTA!
K, jokes aside, I think it's because the car collider is clashing with the wheels collider that's why
It could be indeed your wheels colliding with your car's box collider. A good way to solve this is by setting custom layers for your tires and car, and setting inside the physics tab in project settings so the two layers won't have physical interactions.
@@albertoneto4781 Have the same problem and I tried resolving your way but it doesn't work..
@@Cerions33 maybe check the suspension size? in the gizmos they are those orange vertical lines. If they are too big, your wheels will start to tilt when you keep constantly turning.
I think your wheels may not be oriented right,
Or try this...
Create an empty game object and copy transform from a wheel. After the empty game object is in the position of wheel, you should make wheel object as a child of this empty gameobject. That empty gameobject should be oriented as wheel collider of this wheel and try offsetting the wheel mesh rotation to counter its behaviour in the game mode.
How did the wheels know how to turn graphically?
Thank you so much
GOOD AND NICE WORK
Thanks!
How can I change the direction the wheels rotate in?
When I play it the wheels are rotated 90 degrees and it doesn't work :/ any ideas?
same problem with me did u solve it
Go into the program you used to make the car model and wheels with and rotate the models accordingly
If above dosen't help put the wheel in a empty game object rotate them 90 inside of that object and use that object for placement
seem problem
It's not letting me drop the wheel colliders into the collider section
Where did you find the road mat
my wheel colliders are sideways and it doesent let me rotate them
Thanks a lot!
thanks for tutorial. If you give information about whell collider specifics it would much better. Thanks for good tutorial
The collider doesn't work at all, it goes through on my tire and even when I tried using a cylinder straight from unity itself it still didn't work but capsule collider does for some reason
If anyone wants to add the ability to control what the vehicle's drive type is, I messed around a bit and basically I just created three bools:
public bool fourwheeldrive = false; // 4WD
public bool rwd = false; // RWD (Rear Wheel Drive) 2WD Mode.
public bool fwd = false; // FWD (Front Wheel Drive) 2WD Mode.
Then in the void Accelerate() I replaced the code RC used with this:
if (!fourwheeldrive && rwd)
{
rLWC.motorTorque = m_verticalInput * motorForce;
rRWC.motorTorque = m_verticalInput * motorForce;
} else if (!fourwheeldrive && fwd)
{
fLWC.motorTorque = m_verticalInput * motorForce;
fRWC.motorTorque = m_verticalInput * motorForce;
} else if (fourwheeldrive)
{
fLWC.motorTorque = m_verticalInput * motorForce;
fRWC.motorTorque = m_verticalInput * motorForce;
rLWC.motorTorque = m_verticalInput * motorForce;
rRWC.motorTorque = m_verticalInput * motorForce;
} else
{
Debug.Log("Drive Type not defined.");
}
Hope this helps anyone. Note that you will have to replace all of the rLWC, rRWC, etc. with your variables.
