[Beginner] Arcady Kart drift Help!

Hi,

i'm on a Kart Racing project(as many out there, using mario kart as a basis), and after reading a bunch around here, i decided to not use the wheelcolliders and more realistic stuff.

i tried looking for Youtube tutorials, but none were similar to what i wanted.

Right now my code for the Kart control is like this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CarDrive : MonoBehaviour {
6.  
7.     private Rigidbody car;
8.     public Transform wheels;
9.     public Transform turn;
10.     public Transform Center;
11.  
12.     public float Speed;
13.     public float RotationSpeedWheels;
14.     public float RotationSpeedCar;
15.     public float DriftForce;
16.     public float Y;
17.     public float X;
18.     public float Rotation;
19.  
20.     public bool Drift;
21.  
22.  
23.  
24.     void Start () {
25.         car = GetComponent<Rigidbody>();
26.  
27.     }
28.  
29.     void Update () {
30.         X = Input.GetAxis("Horizontal");
31.         Y = Input.GetAxis("Vertical");
32.  
33.         car.velocity = transform.right * Y * Speed;
34.  
35.         wheels.rotation = Quaternion.Slerp(wheels.rotation, Quaternion.Euler(0, car.rotation.eulerAngles.y + X * Rotation, 0), Time.deltaTime * RotationSpeedWheels);
36.  
37.         if (car.velocity != Vector3.zero && Y>0 && Drift == false)
38.         {
39.             car.rotation = Quaternion.Slerp(car.rotation, wheels.rotation, Time.deltaTime * RotationSpeedCar);
40.         } else if (car.velocity != Vector3.zero && Y < 0 && Drift == false)
41.         {
42.             car.rotation = Quaternion.Slerp(car.rotation, Quaternion.Inverse(wheels.localRotation), Time.deltaTime * RotationSpeedCar);
43.         }
44.  
45.         if (Input.GetButton("Jump"))
46.         {
47.             Drift = true;
48.             car.AddForceAtPosition(turn.forward * DriftForce, turn.position);
49.         } else
50.         {
51.             Drift = false;
52.         }
53.        
54.     }
55. }
56.  

So i have 2 questions:

1- How do i implement drift? i know a bit about the Math behind a drift, but have a hard time putting it in code. I'm trying to do as close as possible of mario kart, as it's a learning project.

I tried playing with some "Turn" point behind the car and appllying a force into it, so the car would spin...and tried to move the center of gravity...but i'm not sure what's the best solution...any ideias?

I was thinking of rotating the car sideways when drifting but keep applying the force in the same direction, however it didn't work out and was a poor solution.



2- the solution i came up for rotation was something i made on my own, and i know there are probably many other that are better without being realistic. However, following the idea that i'm using, can you give me any pointers regarding what i can do better?

I know i have some things to work on regarding going backwards, but it's not the focus right now

i will also change from car.velocity to simple add.force later...maybe that's what's causing some problems?




Sorry for any(many) grammar mistakes, English is my second language.
Thanks for any help/time!

 

Someone can help me?
