Racing Game Guide #3 [ My Suspension method And Logic ] | ashdev 

Impressive approach. My method was very similar when I started. Raycast wheels and Unity default wheel colliders have serious downsides. Also, for an easier setup - create a scriptable object to hold the values of your position spring and damper values. That will basically save your values so you don't have to memorize them.

i was the one who gave pocket wheels the idea of grappling hooks in a car gam! so stoked to see someone talk about that game!

Great explanation of torque and why it important. Also I really like the monster truck and course.

Man, you just save me from missed deadline. BIG THANKS!!!!

Great how u used such awesome examples!

Thank you I was searching for a video like this one for days.

Great explanation. I was looking for a long time to make car controller like this.

Thank you, I have been looking for this lesson for many years

Thank you very much for the shoutout! I really like your method, it seems to be very flexible and looks really good.

this is so simple and clear. Great video!!

Interesting approach! I'm also trying to build a monster truck but I was using HingeJoints and their motors to drive the wheels. Well, it does not really work at all. The wheels start slipping even at low speeds and the truck does wheelies. Low or high friction, nothing really works. The rather complex suspension setup with the joints creates all kinds of problems due to imperfections in the physics simulation. I tried to do a naive but "realistic" implementation, but probably this really has to be faked to work as intended.

Cool stuff, thank you for the tutorial

This is pure gold, thank you

Great video! I'm struggling with finding a formula to calculate the opposite force to be applied. So traction can be applied. Also is that force applied directionally in a diagonal way or is it just applied from the side? I really really like the outcome you achieved and a the whole traction bit is confusing for me.

ok, you made the suspension of the car, but how do you make the wheel spin?

Can you do a lesson about the car controller physics?

Can you please create a tutorial on 2D bike stunt game like Trial Xtreme, Trial Rising, etc. 2D game with 3D models. There is absolutely no tutorials on this topic and no assets at all.

what a great tutorial

how did you Rotate the wheels when you set their angular motion locked? thank you

Great video! May I ask which gameobject you've added the script on? I tried adding it to the parent but the wheels' masses really slow down the vehicle when turning and create problems with sideways forces.

Your game looks nice. I haven’t tried the configurable joints method before but i imagine it wouldn’t handle collisions very well. have encountered any issues with it?

Hi Ash, what is the blue contour around the tires? Is not exactly an outline.. it´s like a light.. How can I search to learn about this?? Post processing? And when you´ll realese Vehicle Physics 2? Thanks!

Hi, very nice explanation! I'm also a bit confused, as there seems to be different advice for which technique is better suited for arcade physics. I'm using Unreal Engine 5 with Chaos physics. And although it is easy to set up and going (it's kind of like you described here, with the bones method), it's is difficult to get an arcadey feel out of it. Although I can easily adjust he friction of the tyres to either slide or grip, it's all too sim-like. Others suggested to go for raycast or even a large sphere around the car, but your video shows that it can be done without those. Chaos even as options to get 'arcade-control' out of it, but is lacking in documentation what each setting is for. I was only able to find out what effect the stabilize controls had. For which I could see through the debug, it was actually creating a force in the opposite direction the car was trying go because of the physics, to counteract the control. Which does a good job at stabilizing the car and also keeping it grounded (if you checked the Z-axis aswell). So I'm actually quite close to that arcade control. Problem is, although I can get the car to drift with pulling the handbrake, it also loses momentum/speed, which makes it a pretty short drift. I need my cars to handle like in Split Second: Velocity. Steering should not decrease the speed and drifting should be able to be done while continue moving forward. Since you're working in Unity, you probably can't help me directly, but do you know of helpfull resources which can help me set it up? Most I come accross are just showing their demo, but not showing how they done it. Coding isn't my strongpoint anymore, so I'm trying it with a combination of the Chaos physics and BluePrints. Cheers.

Hey man, the video's great. I wanna know as to how you got the wheels turning. I added a simple script to the car's root parent object that performs an AddForce function, but it doesn't move because of the wheels.

Hey man this looks great! Are you still planning to make an asset on the assetstore? If not I would like to buy this monster truck example from you.

I have two questions: How do you calculate the sideways component of speed? And do you know how to spin the wheels appropriately? I noticed you suggested, in replies to comments, to apply rotation according to speed. I think it should also depend on whether the accelerator is pressed or not, and on how "drifty" the car is supposed to be (i.e. wheels should spin more when there's less traction). Do you know a simplistic way to calculate this stuff?

Good video! :D Jesus is coming back, God bless!

How did you turn the wheels with Rigid body?. If I turn the wheels, the car would go flying, I froze the unnecessary rotations but still doesn't work. But suspension and Forward-backward movement works. Please help me with the rotation of the wheels.

How do you steer the front wheels so the car can change direction?

Wouldnt turning not work cause with sideways friction it would just stop current momentum but not transfer it into the desired turn?

Do you believe such a setup can work with two or one-wheeled vehicles, like bikes (what about balance?) or even hovervehicles?

Hello, do you know what is the difference between raycast and joints from a performance point of view? I work on mobile and performance is very important.

Hi I don't understand how by blocking the rotation of the wheel it can turn/roll by applying a force. Personally I locked the motion of the configurable joint like you said (and put a physic material) but the wheels don't want to turn despite the movement of the vehicle ... and if i put the motion to free, it do anything

Hey just wanted to ask if the angular x motion is free and if not then how do you rotate the wheels.

After following the instructions, my wheels slide along the car body - any idea why that's happening? The suspension works well, but eventually the car slides forward, as if it's sitting on top of the wheels instead of actually connected to them.

2 years latuur .. any chance of a more in depth tutorial? Most have either wheel colliders or like a single sphere collider ... and that is either very cmplex or very limited in scope (so when you add a jump or boost those controls tend to flip out ...also very limited control over the look and feel)

How do you figure out how much force is applied to each wheel, so you can apply the correct forces when driving? With a raycast suspension, you can just use the forces you apply to the car in order to get it to the correct position, but I can't figure out how to determine the correct forces when using a configurable joint.

Can you also make a script for it

Why don't you use wheelcollider?

could you make a downloadable file , so we can clearly understand the script and other all parts , thank you

i invite to see my game if u like

can i have the code

You are from India? right. but your accent looks like american

ashdev copyer

hey just wanted to ask. is this how you hanled friction? Vector3 frictionDir = new Vector3(-rb.velocity.x, rb.velocity.y, rb.velocity.z); rb.AddForce(frictionDir * Friction);

OMG 😍💋 💝💖❤️
