Camera doesnt move in z coordinate when player falls

I have a problem with camera. The main problem is that if player goes down camera cant follow it
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class camera : MonoBehaviour
{
public Transform target;
public Vector3 positionOffset;
public float smooth = 3.0f;
void Start()
{
positionOffset = gameObject.transform.position - target.position;
}
void LateUpdate()
{
transform.position = Vector3.Lerp(transform.position, new Vector3(target.position.x +
positionOffset.x, positionOffset.y, target.position.z + positionOffset.z), Time.deltaTime
* smooth);
}
}
Here is the link of the problem:https://youtu.be/0RCEmrw3Xho

You missed changing the Y position with the target position. So the correct LateUpdate() should look like this:
void LateUpdate()
{
transform.position = Vector3.Lerp(transform.position, new Vector3(target.position.x + positionOffset.x, target.position.y + positionOffset.y, target.position.z + positionOffset.z), Time.deltaTime * smooth);
}

transform.position doesn't move player

I have a Player (made out of an cylinder, some FirstCam, SecondCam and ThirdCam, for switching views when pressing a certain key - doesn't matter), which is located on a cube (wide enough to take a walk on it). There's nothing else below the cube.
This is how it looks like:
This is the Player's structure:
This is the inspector for Player:
I have the following script ResetToInitial.cs, attached to my Player:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ResetToInitial : MonoBehaviour {
Vector3 pos;
void Start() {
pos = transform.position;
}
void Update() {
if (transform.position.y < -10) {
transform.position = pos;
}
}
}
and also some movement script PlayerMovement.cs that allows him to move up, down, left, right, jump and sprint.
This is PlayerMovement.cs:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
public class PlayerMovement : MonoBehaviour {
public CharacterController controller;
Vector3 velocity;
bool isGrounded;
public Transform groundCheck;
public LayerMask groundMask;
public TextMeshPro State;
public TextMeshPro State2;
public TextMeshPro State3;
// Start is called before the first frame update
void Start() {
}
// Update is called once per frame
void Update() {
float groundDistance = 0.4f;
isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
if (isGrounded && velocity.y < 0) {
velocity.y = -2f;
}
float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");
float g = -20f;
float jumpHeight = 1f;
float speed = 6f;
if (Input.GetKey(KeyCode.LeftShift)) {
speed = 8f;
State.text = "running mode";
State2.text = "running mode";
State3.text = "running mode";
} else {
speed = 5f;
State.text = "walking mode";
State2.text = "walking mode";
State3.text = "walking mode";
}
Vector3 move = transform.right * x + transform.forward * z;
controller.Move(move * speed * Time.deltaTime);
if (Input.GetButton("Jump") && isGrounded) {
velocity.y = Mathf.Sqrt(jumpHeight * -2f * g);
}
velocity.y += g * Time.deltaTime;
controller.Move(velocity * Time.deltaTime);
}
}
ResetToInitial.cs is intended to teleport the Player to the initial position (back on the cube, the position recorded when the scene loads), after he falls of the cube. The problem is transform.position won't move the player anywhere. It won't do anything. I tried to output something in the last if to see if it works, and the output was printed, but still no teleportation happened.
What could be the problem?

Camera always behind player in Unity3d

I'm struggling with this for quit some time now. I have GameObject, being a sphere, which is my player on a 3d Terrain. I have a Camera which is always on a fixed distance from the player, follows it where it goes with below script:
public GameObject player;
private Vector3 offset;
// Use this for initialization
void Start () {
offset = transform.position - player.transform.position;
}
void LateUpdate () {
transform.position = player.transform.position + offset;
}
So far so good. However what I actually want is that the camera rotates with the player, so it always looks into the direction where the sphere is moving, but always stays behind the player at the same fixed distance, so that the player is always visible in the camera view.
There are a lot of scripts available, but the problem with the onces I've seen so far is that the camera indeed rotate with the player, but because the player actually is a rolling sphere the camera view is rolling and turning as well.
The best script I found so far is below, but this one has the same problem as the other onces, the camera rolls with the player.
public Transform target;
public float distance = 3.0f;
public float height = 3.0f;
public float damping = 5.0f;
public bool smoothRotation = true;
public bool followBehind = true;
public float rotationDamping = 10.0f;
void Update () {
Vector3 wantedPosition;
if(followBehind)
wantedPosition = target.TransformPoint(0, height, -distance);
else
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);
//Quaternion ownRotation = Quaternion.RotateTowards;
transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
}
else transform.LookAt (target, target.up);
}
Can anyone help me with this please?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CameraFollow : MonoBehaviour {
public GameObject player;
public float cameraDistance = 10.0f;
// Use this for initialization
void Start () {
}
void LateUpdate ()
{
transform.position = player.transform.position - player.transform.forward * cameraDistance;
transform.LookAt (player.transform.position);
transform.position = new Vector3 (transform.position.x, transform.position.y + 5, transform.position.z);
}
}

My solution (based on #brennon-provencher answer) with smoothness and auto offset:
public class CameraFollow : MonoBehaviour
{
public GameObject target;
public float speed = 5;
Vector3 offset;
void Start()
{
offset = target.transform.position - transform.position;
}
void LateUpdate()
{
// Look
var newRotation = Quaternion.LookRotation(target.transform.position - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, newRotation, speed * Time.deltaTime);
// Move
Vector3 newPosition = target.transform.position - target.transform.forward * offset.z - target.transform.up * offset.y;
transform.position = Vector3.Slerp(transform.position, newPosition, Time.deltaTime * speed);
}
}

You need to move your camera position based on sphere movement direction -
public GameObject player;
private Vector3 offset;
float distance;
Vector3 playerPrevPos, playerMoveDir;
// Use this for initialization
void Start () {
offset = transform.position - player.transform.position;
distance = offset.magnitude;
playerPrevPos = player.transform.position;
}
void LateUpdate () {
playerMoveDir = player.transform.position - playerPrevPos;
playerMoveDir.normalize();
transform.position = player.transform.position - playerMoveDir * distance;
transform.LookAt(player.transform.position);
playerPrevPos = player.transform.position;
}
Edit 2: To fix flickering camera, try this -
void LateUpdate () {
playerMoveDir = player.transform.position - playerPrevPos;
if (playerMoveDir != Vector3.zero)
{
playerMoveDir.normalize();
transform.position = player.transform.position - playerMoveDir * distance;
transform.position.y += 5f; // required height
transform.LookAt(player.transform.position);
playerPrevPos = player.transform.position;
}
}

Make camera follow x-axis only

Trying to make it follow x-axis only. Only follows y when I replace with .y .y
It just doesn't want to work, no matter what I try. (Just started game dev today) I'm pretty noob at coding.
using UnityEngine;
using System.Collections;
public class FollowCamera : MonoBehaviour
{
public float interpVelocity;
public float minDistance;
public float followDistance;
public GameObject target;
public Vector3 offset;
Vector3 targetPos;
// Use this for initialization
void Start()
{
targetPos = transform.position;
}
// Update is called once per frame
void FixedUpdate()
{
if (target)
{
Vector3 posNoZ = transform.position;
posNoZ.z = target.transform.position.z;
Vector3 targetDirection = (target.transform.position - posNoZ);
interpVelocity = targetDirection.magnitude * 5f;
Vector3 factorTowardsTarget = (targetDirection.normalized * interpVelocity * Time.deltaTime);
targetPos = new Vector3(transform.position.x, transform.position.y + factorTowardsTarget.y, transform.position.z);
transform.position = Vector3.Lerp(transform.position, targetPos + offset, 0.25f);
}
}
}

I don't really know much about what I'm doing either, but I gave it a shot. This is my first post.
From what I understand there's a certain order they have to be in, X then Y then Z. And the Y is what was getting the modifier added to it. I just put the modifier on the X position instead.
I tested it, it seems to work.
I just changed this part:
targetPos = new Vector3(transform.position.x, transform.position.y + factorTowardsTarget.y, transform.position.z);
To this:
targetPos = new Vector3(transform.position.x + factorTowardsTarget.x, transform.position.y, transform.position.z);
Result:
using UnityEngine;
using System.Collections;
public class FollowCamera : MonoBehaviour
{
public float interpVelocity;
public float minDistance;
public float followDistance;
public GameObject target;
public Vector3 offset;
Vector3 targetPos;
// Use this for initialization
void Start()
{
targetPos = transform.position;
}
// Update is called once per frame
void FixedUpdate()
{
if (target)
{
Vector3 posNoZ = transform.position;
posNoZ.z = target.transform.position.z;
Vector3 targetDirection = (target.transform.position - posNoZ);
interpVelocity = targetDirection.magnitude * 5f;
Vector3 factorTowardsTarget = (targetDirection.normalized * interpVelocity * Time.deltaTime);
targetPos = new Vector3(transform.position.x + factorTowardsTarget.x, transform.position.y, transform.position.z);
transform.position = Vector3.Lerp(transform.position, targetPos + offset, 0.25f);
}
}
}

This code makes the camera follow the object only on the x position
public Camera MyCamera; // The camera you want to follow the GameObject
public GameObject ObjectToFollow; // What you want to follow
private Vector3 CameraPos; // Variable that contains the Cameras x,y,z position
void Start()
{
CameraPos = MyCamera.transform.position; // stores the Camera's position in the variable
}
// Update is called once per frame
void Update () {
CameraPos.x = ObjectToFollow.transform.position.x; // Change The X position on the camera variable to be the same as the ObjectToFollow X position
MyCamera.transform.position = CameraPos; // Moves the Camera to the new position
}

Move Camera in UnityScript 2d in C#

I have just started programming Unity 2d, and I have faced one large problem: How do I move the camera? The script is attached to the object "player". I want it to move with the player. Thanks!
/*
I
*/
using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour
{
public float speed = 10; //Float for speed
public string hAxis = "Horizontal";
void Start ()
{
//empty
}
void FixedUpdate ()
{
if (Input.GetAxis (hAxis) < 0) //Left
{
Vector3 newScale = transform.localScale;
newScale.y = 1.0f;
newScale.x = 1.0f;
transform.localScale = newScale;
}
else if (Input.GetAxis (hAxis) > 0) //Right
{
Vector3 newScale =transform.localScale;
newScale.x = 1.0f;
transform.localScale = newScale;
}
//Position transformation
transform.position = transform.position + transform.right * Input.GetAxis(axisName) * speed * Time.deltaTime;
}
}

Without any scripts, you could just drag the Camera GameObject to be a child of the player and the camera would start following the player position.
For a script, try this, set player as the target.
using UnityEngine;
using System.Collections;
public class SmoothCamera2D : MonoBehaviour {
public float dampTime = 0.15f;
private Vector3 velocity = Vector3.zero;
public Transform target;
// Update is called once per frame
void Update ()
{
if (target)
{
Vector3 point = camera.WorldToViewportPoint(target.position);
Vector3 delta = target.position - camera.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, point.z)); //(new Vector3(0.5, 0.5, point.z));
Vector3 destination = transform.position + delta;
transform.position = Vector3.SmoothDamp(transform.position, destination, ref velocity, dampTime);
}
}
}
