Drive Cars Down A Hill - Script

If you can't code, you can still achieve a "drive down hill script" effect using:

car.goto(-280, 190)

Attach this script to your car’s Rigidbody object. drive cars down a hill script

using UnityEngine;
public class HillCar : MonoBehaviour
public float motorForce = 1500f;
public float brakeForce = 3000f;
public float gravityScale = 2f; // Extra pull downhill
public LayerMask groundLayer;
private Rigidbody rb;
private bool isGrounded;
void Start()
rb = GetComponent<Rigidbody>();
void Update()
// Check if wheels touch ground (simple raycast)
    isGrounded = Physics.Raycast(transform.position, -transform.up, 1.2f, groundLayer);
void FixedUpdate()
if (!isGrounded) return;
float horizontal = Input.GetAxis("Horizontal");
    float vertical = Input.GetAxis("Vertical");
// Apply drive force in local forward direction
    Vector3 localVelocity = transform.InverseTransformDirection(rb.velocity);
    localVelocity.x *= 0.95f; // sideways friction
    rb.velocity = transform.TransformDirection(localVelocity);
// Main acceleration
    Vector3 force = transform.forward * (vertical * motorForce);
    rb.AddForce(force, ForceMode.Force);
// Extra gravity pull downhill (aligns with world down)
    rb.AddForce(Physics.gravity * (gravityScale - 1f), ForceMode.Acceleration);
// Brake
    if (Input.GetKey(KeyCode.Space))
        rb.AddForce(-transform.forward * brakeForce, ForceMode.Force);

How it helps downhill:
The gravityScale makes the car “stick” to the slope better and roll faster naturally. If you can't code, you can still achieve

Want the car to go faster on steep hills? Add this inside FixedUpdate:

float slopeAngle = Vector3.Angle(Vector3.up, groundNormal);
float downhillBonus = Mathf.InverseLerp(0, 50, slopeAngle); // 0 to 1 between 0° and 50°
float totalForce = motorForce + (downhillBonus * motorForce);

Now the steeper the hill, the more free speed the car gets. How it helps downhill: The gravityScale makes the
