I really need some help and it's frustrating

I cannot fix the Main Camera I tired last night stay up 1am and now it's just getting frustrating for past month as I am focus on this project, but stuck on it. The main camera distorts everything and I even get compiler errors had delete the checkpoint script. I did checkpoint script again of retyped it and failed ten more times. Hours on endless research, As I tried to create checkpoints of other ways that won't work either. I don't know what to do anymore. I am a noob at scripting in Unity, but not totally of a noob as I am somewhat experienced at scripting.

My list things to do is Fix the Main Camera, Checkpoints, fix animator, and DONE.

Where I found Checkpoints lastest one: Video: https://youtu.be/X11SBMwegaA

What information you'll need to know? I've made a video https://youtu.be/GsIK6UZ1jT8

AND

The Main Camera Script: Script Name: SmoothFollow.cs

using UnityEngine; using System.Collections;

public class SmoothFollow : MonoBehaviour { public Transform target; public float smoothDampTime = 0.2f; [HideInInspector] public new Transform transform; public Vector3 cameraOffset; public bool useFixedUpdate = false;

private CharacterController2D _playerController; private Vector3 _smoothDampVelocity;

void Awake() { transform = gameObject.transform; _playerController = target.GetComponent(); }

void LateUpdate() { if( !useFixedUpdate ) updateCameraPosition(); }

void FixedUpdate() { if( useFixedUpdate ) updateCameraPosition(); }

void updateCameraPosition() { if( _playerController == null ) { transform.position = Vector3.SmoothDamp( transform.position, target.position - cameraOffset, ref _smoothDampVelocity, smoothDampTime ); return; }

if( _playerController.velocity.x > 0 ) { transform.position = Vector3.SmoothDamp( transform.position, target.position - cameraOffset, ref _smoothDampVelocity, smoothDampTime ); } else { var leftOffset = cameraOffset; leftOffset.x *= -1; transform.position = Vector3.SmoothDamp( transform.position, target.position - leftOffset, ref _smoothDampVelocity, smoothDampTime ); } }

}
