Hello !
I'm also trying to put a car in the flying game. I used to think about it, but I didn’t get anywhere. In fact, I'm still stuck. What is seen is not much different from the dynamics of the plane. we move an object in a plane that has velocity and direction. We modify the direction vector with the new direction created by the drift. But I got stuck.
I want you to travel in the mountains, on the hills, and the shock absorber would also be useful. I want you to tip over. This, in turn, is a much more complex approach. I would like to ask you for ideas, links, literature to see if anyone can help. where can i find writing about the physics of a car?
I created an environment for experimentation. You can try this, go with it, you can switch between 4 camera views with the C key, the current options will be displayed on the screen.

MasterGy -

This is such an excellent endeavor, and you've done an awesome job with the vehicle already! So car physics... we should be able to derive all that, if anyone wants to supply links that's their business.

As for the car flipping over... This can be intricate business to get exactly right, especially when in motion. Speed factors into whether you tip over or not, so how do we model all this? I'll start:

(1) Calculate (or convincingly estimate) the center of mass of your vehicle. This will be a 3d vector landing somewhere near the middle of it, basically. This number will have to change depending on what your shock absorbers are doing from moment to moment.

(2) When the car is in any given certain position on your terrain, place an imaginary point under each tire, and connect those imaginary points with imaginary lines to make a closed, 4-sided shape. In general, for bumpy terrain, this 4-sided wireframe won't be flat or level. (This frame can serve as the basis for determining the normal vector the vehicle and help render it at a slant.)

(3) View this wireframe shape from above (take the z-projection) and it flattens to a rectangle. If the ground was very slanted, you'll get a rather small rectangle. If the ground was perfectly flat, you get the biggest possible rectangle. The benefit of shock absorbers would be to increase the size of this projected rectangle.

(4) Project the center of mass vector onto the same plane, which will effectively place a dot either inside or outside the projected rectangle. If the dot lands outside the rectangle, the vehicle flips over.

This picture is actually not exactly what im describing but it does have the center of mass and you can imagine the "wireframe box"

... All that's true "At Rest" (or true enough for low speeds) ...

To do all this while in motion, you need Newton's second law to factor in. Friction, torque, centripetal stuff, oh my... Like for example, if you're driving along at a good speed, and then suddenly turn the wheel as hard as you can, the vehicle flips like crazy, even on flat ground. Do you want to capture all of those dynamics too?

You're not done when it works, you're done when it's right.

thanks for the advice and for checking it out. Good idea STxAxTIC what you wrote! I'm just drawing for now, I'm trying to understand. I hope you succeed one day.

I'm getting up with this lately, I'm lying with this. Before I write the move for the game, I first try to understand the dynamics of the vehicle in 2d, it’s very complicated and by the time I get there, it’s false. The behavior is not realistic. Knowledge of solid body physics or rigid body physics would be required. In vain, there are many descriptions on the Internet, but so far they have not been applied effectively. No problem, I won't give up!

Re: car simulator
« Reply #5 on: November 26, 2021, 02:05:10 pm »
The car goes in the field. Cheats a lot, it's not real physics. I’ve learned a lot from it by now, if I have the time and mood, I’ll do it all over again. I want it to roll over and use the shock absorber as it should and the whole car should have normal dynamics. Right now, the way I’ve solved things is a bit confusing.
4 camera views, can be switched with the C key. camera-car distance * / buttons, camera-height + - buttons.

you’ve been thinking about what if you go fast in a car and lower the steering wheel as fast as you know, what happens. the car starts to spin. but what is it worth doing then? it is very interesting that this problem has come to light, because from here on, it is hard to imagine what a good position the wheel is to dampen the spin. it is interesting how this problem returned in mathematics because it was unable to turn greater than 180 degrees. very interesting. or just me? it was hard to imagine even in reality, but I could solve it. now really good! try it out and enjoy the car drifting back and forth.

I really want to make something out of it. car, flying with approximate dynamics, and automatic control. you just have to give them a goal and do everyone’s thing. I'll show you soon.

It will be ready soon, I will not give up now.
The gameplay will be easy and I hope it’s fun.

MasterGy, this is (going to be) already amazing, looks so good.

Looks like we're getting a game for Christmas bois... or maybe for New Years?

I want to finish as soon as possible because I’m slowly going crazy. Get a simple storyline that makes it playable and expose. I want my brain cleared for the holidays before Christmas.

Hi !
Almost finished. Sounds are still missing (collision, wheel squeak), but both the car and the plane managed to give a speed-proportional, real sound. Balance okay, stereo.
In principle, there are no faults in physics or collisions.
The first half of the video (until 4:20) shows a complete fight, with each player controlled by a computer. The point is to get the bullet from the other and take it to the tornado. That’s where a pretty exciting chase begins.
In the video, after 4:20, I show that if I move the mouse over the object in the list, we see the world from his point of view. If I don’t bring the mouse to anyone, the cinema-mode camera remains, which doesn’t even take its eyes off the bullet.
If, on the other hand, I click on one, it gives me control and I control it.
For a few more days, I’ll make a menu, a simple interface, and expose the game.
I recorded the video in an audio multichanel and made sure it stayed that way when converting. Unfortunately, I don’t think you’re going to play 4 speakers in anyone, just stereo.
