man i was struggling trying to make my own car physics system, then i finally gave up to the wheel collider, thanks for the help dude!

[@IanFord-e6w]

Hey there, just wanted to drop in and say thanks for this. Recently started doing stuff in Unity and this tutorial was very well put together. Quick, to the point and super easy to understand.

[@aneskaric]

No complicating, precise and straight to the point! Thanks!

[@b3agz]

All the things I was aiming for! Thanks!

[@joethewolf3750]

Thank you. Out of the ones I've seen, this tutorial seems the most fitting for my project and it's one of the simplest to do and understand as well. I think I'm gonna use it. It's really relieving to have found something I can work with because when I was given the task to make our car less janky, I was really stuck on how to do it. (At its current state, the car just goes sideways without turning when you press A or D so... It's dire and I didn't have much to work with.)

[@nayefmsh8274]

Wow, this tutorial was actually helpful out of the millions of other videos I watched

[@bigedwerd]

You're a lifesaver. I was struggling with localEulerAngles unnecessarily for the wheel angle and this helped immensely.

Thanks man. I was struggling with wheelcolliders a lot until I came across your video. well explained!

[@thesoulmonster]

This is a fantastic video! I used this for my scooter, which has two wheels, and your video was so good and self-explanatory that I was able to make it work anyway.

[@DOHCKSeries]

awesome tutorial, great job explaining what the code actually does in a beginner manner so it's easier to take in

[@ivancarranza2473]

Woah !!!!! What can I say that's probably has not been said in the comments already? Amazing tutorial, so simple so to the point, so useful. Thanks a lot! I will be going through the rest of your youtubes to see what other amazing tutorials have been missing all my life. Thanks again.

[@TMosier88]

If anyone is having trouble getting the car to move, try turning the mass down a bit. I'm using Synty assets and my mass is set to 200. I also adjusted Acceleration to 100 and braking force to 60 but I'll play with those values later on. Also, if anyone wants to use the new update system, just change the currentAccleration = acceleration * Input.GetAxis("Horizontal"); to currentAcceleration = acceleration * inputAction.YourActionMapName.YourVector2BindingName.ReadValue().y;

[@katvivala873]

Hi Travis Thank you for that comment, I actually ran into this issue, the car is moving like a pudding. It hops a little bit forward, but it doesn't stay on the road and just move forwards. Do you have any other advice? I used mass 90, accelleration 100 and breakingForce 60. When putting mass down, then it moves upwards.. Also I wanted to ask you, what do you mean with the new update system? Actually I didn't used the asset from b3agz, I used another car with 4 wheels - much more simple than this one. But should work as well, shouldn't it? Many regards

[@TMosier88]

@@katvivala873 I meant the new input system, not update. Just a typo in my part. Without seeing your code, I couldn’t say what’s going on with your movement. But yes, another car asset should also work, I also used a different one

[@katvivala873]

@@TMosier88 Thanks for replying. Well I used the same code as he did, but maybe there is something else wrong with rigidbody or colliders. I think my issue is, that the wheels are rolling in the wrong way.. the back one's are going backward and the front are moving in front. Do you maybe now how to change it? As the rotation didn't help I'm a little lost. Or maybe you, @b3agz ? Many thanks, Kat

For anyone struggling with the car moving really slow or not even budging (especially for Synty Asset Cars) play around with the wheel collider Y position and radius in game mode, I noticed if it is too large of a radius and or too low to the ground it causes the car to not move. Hope this helps :)

[@gabbargamer2007]

If it is slow then can't we just increase the acceleration???

[@skourge891]

@@gabbargamer2007 it was a matter of the wheels not properly colliding with the road, so the wheels would spin but the car wouldn't move, from memory.

[@gabbargamer2007]

@@skourge891 Then I think u used reduce the size of the collider, I mean if t radius of the cars wheel is let just say 8 then use collider a litter but smaller than that, only a little bit so that it doesn't stuck in ground and also make sure to merge the movement of collider and mesh

why tf the stupid wheel collider is always not in the correct orientation and why it couldn't be rotated? the wheel is always facing the collider by its side and it can't be rotated

[@sabmis2658]

Has to do with the orientation of the car. You can take it in to Blender, rotate it facing the y axis.

Thank for the great video! Helped me to get started very well. Issue I have is that when I place the wheel colliders and press Play, the wheels of my car-model change position (they move outwards a bit and the tire&rim, which are two separate assets, are disconnected.

[@MrMattyMoses]

this is awesome! thank you so much for making this. it was so cool seeing my car basically come to life thanks to your video. The only thing I'm struggling with is getting the car to move any faster? I've bumped up the acceleration to 5,000 and it barely speeds up. I dropped the mass down to 500. All of the wheels are spinning the correct way. Anyone find a fix for this? I saw someone else in the comments say their car was moving like it's in pudding. That's where I'm at. Once I fix this I'll be in the clear.

Hi,I just tried this and works very well but I have a problem,when I press W it goes back and when I press S it goes forward(I put all the colliders right)

It sounds like the input had gotten mixed up. When you convert the player input to vehicle force, stick a - before the value so it reverses it.

Thank you,it was the car's problem,I changed it and now it works

First of all, thank you for this video. It's well done. But I have a problem.

@@allblakesmusic1606 yeah, had to adjust the origin of the wheels. I had it in the center of the car, so I adjusted it to the center of the wheel itself and reimported the model. Worked for me.

[@Kvarget]

Been following the exact same steps, wheels' location and rotation is 0,0,0 and applied in Blender. Unpacked the mesh. Wheels keep floating 2 meters or so next to where they are supposed to be after I add the UpdateWheel function. I just can't figure out where this bs is misbehaving from :( Other than that, good vid!

[@kyleconrad9861]

Same 😔

[@TheDznation]

Now how can I do this but with buttons like a mobile racing game

[@eagle9717]

Hey Quick Question, when you release the up or down keys, the car still stays the same speed, which makes sense, since you only control the acceleration and not the speed. Is there a way to make the car loose speed when the buttons are released? Thank you very much for the video, it really helped me out!!

[@UltimateVenom84]

have you tried adding a small amount of drag to the Rigidbody?

[@Sharkzy_]

hello i have a issue where my car model doesn’t actually turn it just slides in the input direction, what could caused this?

[@b3agz]

Best guess would be the mass/friction values of your physics objects. Maybe try making your vehicle heavier and see if that changes anything.

[@jannahconsortium4521]

Awesome can I use the same method for oculus quest controllers instead of keyboard?

[@b3agz]

The mechanics will work the same yeah. You just need to swap out keyboard input for some kind of oculus control. I believe you can get direct axis info from the touch controllers but prob wouldn't be very intuitive if you didn't do something a little more fancy.

[@DinciAnimation]

plz man tell me bro how can i just make a ui button witch rotate my car backward and forward

Hi! Thank you for your great work on that tutorial. I have a question - How to deccelerate when verticals are not pressed. Cuz if I press W for like 2 sec car is still running and won't stop. Any advice? Should I add if statement and apply break force if not pressed?

[@Elsidu]

Ok. It's not that case. I've noticed that even doe I'm not pressing W or S the wheels are still spinning round and round. I guess it has to do with friction but for now I can't setup that right...

[@junaidjamshed8104]

Hey select your whole car parent object right click and then go under prefab and click on Unpack completely

[@kyleconrad9861]

I’m following fine until we add rotation to the wheels. The wheels float well outside the car and spin in big circles to the side, as though they’re orbing the car or rotating around another axis as opposed to in place. Not sure what to do with it, all my code matches up.

[@kyleconrad9861]

For anyone with my issue or a similar one, it’s related to the pivot point of the wheels. I downloaded an asset where all 4 wheels picot around the center of the car, not the center of each wheel. You can fix this by changing the pivot of each wheel. 👍

[@beqasamadalashvili9058]

Nice tutorial but my tires are out of the car im using same asset

[@b3agz]

Try creating an empty game object for each wheel and having the code reference the empty object instead of the wheel directly. Then make your wheels children of the respective empty objects and set their local position so they're in the right place.

Not a lot you can do with that, unfortunately. You can either have the "wheels" be invisible and unconnected to the card (there won't be any visible spin or turning though) or you can crack open Blender and try and separate the wheels. Or use a different model.
