Description

This is designed to make a camera smoothly follow a ship in space.

Usage

Place this script onto a camera.

JavaScript - SmoothFollow2.js

var target : Transform;
var distance = 3.0;
var height = 3.0;
var damping = 5.0;
var smoothRotation = true;
var rotationDamping = 10.0;

function Update () {
	var wantedPosition = target.TransformPoint(0, height, -distance);
	transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

	if (smoothRotation) {
		var wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
		transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
	}

	else transform.LookAt (target, target.up);
}

C# - SmoothFollow2.cs

using UnityEngine;
using System.Collections;

public class SmoothFollow2 : MonoBehaviour {
	public Transform target;
	public float distance = 3.0f;
	public float height = 3.0f;
	public float damping = 5.0f;
	public bool smoothRotation = true;
	public float rotationDamping = 10.0f;
	
	void Update () {
		Vector3 wantedPosition = target.TransformPoint(0, height, -distance);
		transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

		if (smoothRotation) {
			Quaternion wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
			transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
		}
		
		else transform.LookAt (target, target.up);
	}
}

C# - SmoothFollow2.cs (Improved)

using UnityEngine;

        public bool followBehind = true;
        public float rotationDamping = 10.0f;

        void Update () {

               if(followBehind)
                       wantedPosition = target.TransformPoint(0, height, -distance);

               transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

               if (smoothRotation) {
                       Quaternion wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
                       transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
               }
               else transform.LookAt (target, target.up);
         }
