Unity3D Need for Speed Car Movement - Camera Controls

Copy the below code and paste it into a c# file in Unity3D
named cameraController.

using UnityEngine; using System.Collections; public class cameraController : MonoBehaviour { public Transform car; public float distance = 6.4f; public float height = 1.4f; public float rotationDamping = 3.0f; public float heightDamping = 2.0f; public float zoomRatio = 0.5f; public float defaultFOV = 60f; private Vector3 rotationVector; void LateUpdate(){ if(car != null){ float wantedAngle = rotationVector.y; float wantedHeight = car.position.y + height; //car.position.y + height; float myAngle = transform.eulerAngles.y; float myHeight = transform.position.y; myAngle = Mathf.LerpAngle(myAngle, wantedAngle, rotationDamping*Time.deltaTime); myHeight = Mathf.Lerp(myHeight, wantedHeight, heightDamping*Time.deltaTime); Quaternion currentRotation = Quaternion.Euler(0, myAngle, 0); transform.position = car.position; transform.position -= currentRotation*Vector3.forward*distance; Vector3 temp = transform.position; //temporary variable so Unity doesn't complain temp.y = myHeight; transform.position = temp; transform.LookAt(car); } } void FixedUpdate() { if(car != null){ Vector3 localVelocity = car.InverseTransformDirection(car.GetComponent<Rigidbody>().velocity); if (localVelocity.z < -10.5f) { Vector3 temp = rotationVector; //because temporary variables seem to be removed after a closing bracket "}" we can use the same variable name multiple times. temp.y = car.eulerAngles.y + 180; rotationVector = temp; } else { Vector3 temp = rotationVector; temp.y = car.eulerAngles.y; rotationVector = temp; } float acc = car.GetComponent<Rigidbody>().velocity.magnitude; GetComponent<Camera>().fieldOfView = defaultFOV + acc * zoomRatio * Time.deltaTime; } } }

This code is inspired from a javascript version of the below video
