2D Camera Follow Jitter

Unity Engine
1

Hello, I need assistance with my Unity Project. Normally the jittery camera comes from when the camera tries to update before the player is finished moving, but for some reason in this case the character is the one jittering on their own. I’m pretty stumped as why the character is jittering. They physics code is based off of the 2D custom gravity course.

PhysicsObject2D:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PhysicsObject2D : MonoBehaviour
{
    //Editable Variables
    public float gravConstant = 1f;                   //Modification to Physics Gravity

    //Class Variables
    private Rigidbody2D _rb2d;                        //Reference to RigidBody2D
    private Vector2 velocity;                         //Velocity of the object

    private void OnEnable()
    {
        _rb2d = GetComponent<Rigidbody2D>();
    }

    private void FixedUpdate()
    {
        //Increase downward velocity while in the air
        velocity += gravConstant * Physics2D.gravity * Time.deltaTime;


        //Move object
        Vector2 move = Vector2.up * velocity.y * Time.deltaTime;
        _rb2d.position += move;
    }
}

CameraFollow:

using UnityEngine;

public class CameraFollow : MonoBehaviour
{
    //Public Variables
    public Transform target;                //Camera Target
    public float smoothSpeed = 0.125f;      //Camera lag speed
    public Vector3 offset;                  //Offset for the camera position

    private void LateUpdate()
    {
        //Get Desired camera position - Player's position
        Vector3 desiredPosition = target.position + offset;
        //Smooth the camera's movement using linear interpolation
        Vector3 smoothedPosition = Vector3.Lerp(transform.position, desiredPosition, smoothSpeed);
        //Apply the lerped position
        transform.position = smoothedPosition;
    }
}

Why aren’t you using Cinemachine for the camera? It’s far easier than rolling your own camera script.

Also, it might be better to use _rb2d.MovePosition().

I’m still new to Cinemachine, so I thought I could explain my situation better with the script I was originally using.

I’ll give MovePosition a shot and see what happens.
