The word "Cartoony" should be added to the video title

how to i actually apply this on m y project ? the code are there and the explanation how its work too, but im using a different engine with different methods and language...

I don't quite understand how the sticky to slope is implemented. My character, when walking upwards on an inclined surface, sticks too much to the surface, and when it descends, it stays too high, causing the character to make small falls. This is my code that implements the ground hover: public void GroundHover(float hoverHeight, float frequency, float dampFactor) { Vector3 origin = transform.TransformPoint(_capsuleCollider.center); bool rayDidHit = Physics.Raycast(origin, Vector3.down, out RaycastHit hit, Data.rayLength); if (rayDidHit) { float mass = _rigidbody.mass; Vector3 vel = _rigidbody.velocity; Vector3 rayDir = transform.TransformDirection(Vector3.down); float springDelta = hit.distance - hoverHeight; float springStrength = frequency * frequency * mass; float dampStrength = 2 * mass * frequency * dampFactor; // spring speed Vector3 otherVel = Vector3.zero; Rigidbody hitBody = hit.rigidbody; if (hitBody) { otherVel = hitBody.velocity; } float rayDirVel = Vector3.Dot(rayDir, vel); float otherDirVel = Vector3.Dot(rayDir, otherVel); float relVel = rayDirVel - otherDirVel; // add force float tension = springDelta * springStrength; float damp = relVel * dampStrength; float springForce = tension - damp; _rigidbody.AddForce(rayDir * springForce, ForceMode.Force); if (hitBody) { hitBody.AddForceAtPosition(rayDir * -springForce, hit.point, ForceMode.Force); } } } My parameter values are: - hoverHeight = 1.2f - frequency = 15f - dampFactor = 0.55f

Wtf is PhysicsOneUpdatePerFrame I can't find any documentation on it

amazing

This video is fantastic man. exactly what I needed

I am not some advanced programmer so if there is some github file to look at...I would love to check and understand.

very nice. From what i saw you have no gears... just a "max speed". My sim was getting too technical for what I want but this looks like the right blend of realism without so much technical detail. Getting a good solid base 1st then extras is the way to go. Had a test facility for testing but seen how inadequate it is. I'm adapting this approach now and got the RGB transform vectors in the debug working nicely now. I also ripped out the gears code... and made it so the torque lookup is with normalized values. Car also now just has a top speed and a maximum torque.

This rigidbody or character controller?

Could you make a more detailed tutorial on how to set it up?

I guess you're more interested in making games than making devlogs/tutorials-- based btw --but you've clearly got the chops to do this youtube shit as well. I eagerly await whatever you do next.

How did you create such nice explanatory Animations for your video?

Very cool 👍

Such an amazing breakdown! I think the VehicleBody3D that's built in to Godot is based off of this exactly 😂 Seeing how simple it is, I might just try and implement it myself.

This is great

Make game devs teach physics in schools and colleges and we'll be making our own flying saucers in a few years

16:19 you can even change the grip depending on the spring tension, to make it more realistic (for example, if you're accelerating on a rwd car, the weight is at the back, making the front tires have less grip) Also, how do you measure the wheels' velocity without having rigidbody on them (and being able to drive around without them)?

This video helped me a lot to understand how to make physics calculations through code!

Thank you SO much for this tutorial, it helped a *huge* amount with the car physics in my game. 🙏

Hi thank you for this awesome video, however I have one question, does the ray cast start from the wheel position ? or it starts at the wheel pos + rest length? I would love to see the raycast data used, it is not clear yet for me.. Thank you

11:45 I might be wrong, but I think the tireWorldVel should not be in world space, but in local space of the suspension anchor. For a car, the problem is probably negligible though, since the dot product eliminates most of the world velocity since usually the spring is close to orthogonal to the ground. Implemented a similar thing for a kind of self-stabilizing one-hweel and did the same mistake initially, which meant at very fast speeds my spring would be more dampened when the vehicles leans a lot. You can do some vector algebra to get the correct wheel velocity relative to the spring though.

Like I see you just setting a value to something, like with the nudge example where you add to VelocityScale, and then it should “just work” but I’m not entirely sure why it just does

I just need some explaining cause maybe I’m missing something huge. Looking at your very first example implementation for the button, I don’t see how the goalPosition value is mapping onto the SpeingUpdated function? I don’t see an overlap in values? I feel lost but I must be just missing something obvious?

AWEEEEEESOME sauce!!! this tutorial is awesome man!1

Can we use this code in any project without any fear of copyright

Unbelievable

Although, the video is great, the code doesn't mention the sideways friction curves implementation you talked about at 17:50

I was watching the suspension part, so even if we put infinity weight on the car, the suspension is bound to come to rest distance eventually?

Maybe you guys Ineed Update like Freedom and Multiplayer hangout maybe something like that

Wow, very impressed. The game I'm working on uses (mostly) hover vehicles, so I was already using a setup similar to yours (floating "characters" with continually calculated strength and dampening forces). But you guys have really taken it to the next level with improvements that I hadn't thought of at all. Thanks!

Just checking for Rigidbody tutorials and I saw your video. While I was watching, I was wondering what game was playing in the background. Then I found out about this gem, LOL. Definitely will try. Perfect tutorial and perfect advertisement. Good job, by the way.

What is speedFactor at 4:02?

A lot of this reminds me of testing out springs in Verlet integrations and Kabsch. ;w;

This is a great solution. Love it.

You could become the new "brackeys". You really have a great talent for tutorials

man, this is such a hidden gem. i dont know why i dont know your channel earlier

Hey please make more tutorials!

It might happen to you that if you steer the wheels right and left really quickly, your car starts flying in the air. I will show how to solve it. I'm not sure why it happens, but it is related to the imprecision of simulated physics, maybe the grip force glitches and pushes the car more that it should or something. To solve it, you want to make it so the input (controller joystick probably) doesn't directly translate to the wheel steering but instead move to that direction for the previous one. To do this, you should use the lerp function, you can look it up in the Unity Documentation. Here it is how I solved it: Vector2 steeringInputValue = steeringInputAction.ReadValue<Vector2>(); float targetSteeringValue = steeringInputValue.x; //this is the value of the joystick, you may be getting it differently currentSteeringValue = Mathf.Lerp(currentSteeringValue, targetSteeringValue, 5 * Time.deltaTime); Vector3 previousRotation = wheelTransform.eulerAngles; wheelTransform.eulerAngles = new Vector3(previousRotation.x, transform.eulerAngles.y + currentSteeringValue * 45, previousRotation.z); Bye

This is brilliant. I'm currently fighting with wheel colliders to get the exact semi-realistic arcade-like feel that I want - with predictable controls to be able to increase stats over time without the physics of the car going haywire and it's driving me potty

How you make a lookup curve?

It would be great to hear what exactly do you use as the tireMass parameter at 17:58 for computing steering force, because this can affect whether the wheel is capable of producing the force that results in a greater opposite velocity than the one from the previous frame and make the simulation unstable.

Would this be three separate scripts we’d have to attach to the just the body of the car?

this is one of the smartest custom controllers I've ever seen, so impressed with yall's work on this

Great tutorial!

Thank you so much for the content! I have a question. I've coded out everything as described in the video, but my rigid body ends up tilting to one side, and despite being a perfectly balanced body with equal forces on each corner, it can't right itself. To make things worse, the "suspension" force ends up acting as a forward propulsion force because the tilt gives it enough of a non-vertical direction to propel it forward, despite having 100% grip all around. Do you have any recommendations for this?

We need more people like you on youtube! You video looks like a AAA budget NatGeo Documentary! Love you! I would like to pay for this type of content rather than college degree or bootcamp🔥💪♥️🤩💥

How would I add a maxOffset to my suspension?

+1 sub for being the only correct character controller I've ever seen talked about.

I am confused about the two grip factor curve in the steer part （the two curve in one same graph）. which one is for the front tire and which one is for the rear tire?
