How to make camera smooth when following player

Question

When my character moves through my cameras 'FollowPlayer' script, the background just looks really glitchy and bad Is there anyway to fix this?

This is my script:

using UnityEngine;
using System.Collections;
public class FollowPlayer : MonoBehaviour {
    Transform bar;

    void Start() {
        bar = GameObject.Find("PlayerMovingBar").transform;
    }

    void Update() {
        transform.position = new Vector3(
            bar.position.x, transform.position.y, transform.position.z);
    }
}

Answer 1

Using Lerp will give a smooth following effect as @Hellium mentioned. It's also recommended to use it in the LateUpdate() method.

See Unity documentation for that : MonoBehaviour.LateUpdate()

Good luck on your project!

Answer 2

You may simply need to Lerp to the desired position :

public float followSpeed = 10 ; // Change the value here to have the desired result

void Update() {
    Vector3 targetPosition = new Vector3(bar.position.x, transform.position.y, transform.position.z);
    transform.position = Vector3.Lerp( transform.position, targetPosition, followSpeed * Time.deltaTime );
 }
