A fully self driving car in Unity from scratch using Neural Networks and Genetic Algorithms! Yes I said from scratch, we will be coding everything ourselves so that you can understand from the base up how everything works. I have been working on this video for quite a while to make it the best I can for you ❤ Of course you can apply all of these concepts and techniques into your own games, research and simulations.

Hey uh, I just turned 18. You're a few years younger than me, and I'm so impressed and inspired by the amount of knowledge and dedication you have to programming and coding. I just want you to know that it's inspired me to finally try it out for myself, and hopefully, I can catch up to you one day. Thank you.

been making my own race course in blender for some experience, would this still work if i had a mesh collider on my plane where the grass is instead of a separate cube on the outside of the track pls?

@GameJarne Год назад

This video helped me out so much, tysm! I do want to suggest you to not use variables like “v” or “h”, you don’t need to make your code compact, you should make it readable. Never use a single letter for a variable name! Also hardcoding is fine imo, but to make it easier to know what the values mean, you can declare variables in the function instead.

@nonenone7285 4 года назад

@adriantili6918 5 лет назад

About totalDistanceTraveld , you could initiate lastPosition with startPosition then in colision before reseting it you give to lastPosition the transform.position so like this you calculate the distance between starting point and colision point in one go not every frame

@batchprogrammer108 4 года назад

The problem with this is, since it's a circular course if I did this then it would provide an inaccurate distance value because Vector3.Distance calculates a straight light distance. It will actually calculate displacement not distance

@jacklamb1155 4 года назад

Hey! The first thing is that I really appreciate this video, it's helping me out a lot with a neural network I have to create for an assignment of mine. However, I have encountered an issue I can't fix. In the InputSensors method, of the 3 sensor values, I have only c that actually has any values that change. Happily, it is between 0 and 1 but a and b remain at 0 unless I make unusual sharp turns in the Inspector. Any clue as to what could be causing this? I reviewed the code and compared it to yours but as far as I can see it's all good.

@batchprogrammer108 4 года назад

Thank you for the compliments Jack, I can think of a few things that may be wrong. I'm not sure if you're using your own course setup; if so in the code there is a hit.distance/20 - i did that to keep it between 0 and 1 you may have to play with that a little as the scale of your course may be smaller than mine. So change the 20 to a variable and try playing with that in the inspector. Second thing that may be an issue is the ray is possibly colliding with the bounds of the car, so you may have to use a LayerMask to ensure that it isn't hitting the car. So based on the details you have given me, the distance issue seems to be more probable. Please try that, and if it doesn't work then maybe send some screenshots or a GitHub link to ajays.workemail@gmail.com and I'll reply to you within today :)

@jacklamb1155 4 года назад

@ZenitDS 3 года назад

You forgot a very important thing in Unity, MOVEMENT SHOULD ALWAYS BE RELATIVE TO TIME. You should have used Time.deltaTime or Time.fixedDeltaTime instead of 0.02f. Also in the part where you add the time to the timer you should have used Time.fixedDeltaTime instead of Time.deltaTime since it´s a FixedUpdate() function.

@prathamesh_sinha 2 года назад

Do you always run in a uniform speed? Does your car always move on a fixed speed? Did you listen to what he said? He said that he did that by choice cuz there is almost nothing like uniform speed in real life. Yes, the second this is correct actually.
