hello. it's amazing what you can do with qb64. impressive. that said, you should always have a standard way to exit a program. usually it's by using the escape key.

Thanks Coolman ! I'll add the exit. And here I tried out the control and dynamics of the car. I still see mistakes in the dynamics, but it is interesting that it has remained.

Thumbs Up 
@MasterGy you have a profound understanding of three-dimensional graphics programming and don't even need to do it in a payware programming system! It makes me even more ashamed I invested in Purebasic...

Thank you for this great example, and keep up the good work.

I'd love to see this code broken down and explained - it's all machine language to me! Haha. Really great to see what can be done with QB64. Thanks for posting, glad to see this.

Dug in and fiddled with some of the variables to see what would happen and I am impressed even more. Cranked up the gravity and spread out the curves (to create difference in driving space) and decreased the vehicle power and the physics respond really well.

I am very glad that you will try it! I'm even more happy if you confirm the values. I calibrated it for a long time to make it enjoyable. You may have a better setup. If you can do better, I'd be happy to see it.
My original goal was for the car to actually move. Unfortunately, this has not yet been achieved. This uses the laws of rigid-body physics only slightly. For example, the car cannot roll over. Or if we go up a hill at high speed, it doesn't fly as it should. Small mistakes. If I have time, I would really like a realistic simulation where the car rolls over like it does in real life.
If I have time, I would like a simple description of the 3D view and, if you are interested, also of this program, what it does.
