how to make a car controller in unity code example
Example: advanced car movement script unity
using UnityEngine;using System.Collections; public class CarController : MonoBehaviour { public WheelCollider WheelFL; public WheelCollider WheelFR; public WheelCollider WheelRL; public WheelCollider WheelRR; public Transform WheelFLtrans; public Transform WheelFRtrans; public Transform WheelRLtrans; public Transform WheelRRtrans; public Vector3 eulertest; float maxFwdSpeed = -3000; float maxBwdSpeed = 1000f; float gravity = 9.8f; private bool braked = false; private float maxBrakeTorque = 500; private Rigidbody rb; public Transform centreofmass; private float maxTorque = 1000; void Start () { rb = GetComponent<Rigidbody>(); rb.centerOfMass = centreofmass.transform.localPosition; } void FixedUpdate () { if(!braked){ WheelFL.brakeTorque = 0; WheelFR.brakeTorque = 0; WheelRL.brakeTorque = 0; WheelRR.brakeTorque = 0; } //speed of car, Car will move as you will provide the input to it.
