Sprite not Appearing in Unity 2D Game

I'm creating a 2D Top Down game for practice and I need a little bit of help. For context, it's a 2D Top Down Shooter game, where you can move and shoot enemies. The enemies have a basic radius system where if the player gets within the radius, it'll approach the player.
Now I'm making a game mechanic where the player can hide in a cardboard box, the player can press 'E' and he'll suddenly become a cardboard box, where if the player is in the cardboard box, the enemy doesn't detect him even if the player's within the radius. Yes, just like in Metal Gear. Now I've created the prefabs and everything and functionality-wise, it works perfectly. If you press 'E' the enemy cannot detect you.
Now the small problem is that the cardboard box didn't appear, so it's just the player disappearing entirely. I do not know what caused this problem.
For context, these are my scripts. Feel free to read them, or not :)

{
case "Wall":
Destroy(gameObject);
break;
case "Enemy":
Destroy(gameObject);
other.gameObject.GetComponent<EnemyController>().DestroyEnemy();
break;
}
}
}
I've tried tinkering my scripts, I've tried checking if there are any missing components in the cardboard box game object but to no avail. Although I might be wrong on the Unity part since I'm fairly certain that the script isn't the problem here, again might be wrong.
I appreciate all the help I can get, thank you for reading until here

How I can move player left or right with infinite runner game here. using character controller

public class PlayerMove : MonoBehaviour
{
public float speed;
private float yVelocity;
public CharacterController player;
public float jumpHeight =10.0f;
public float gravity = 1.0f;
//public float gravityScale = 1;
private void Start()
{
player = GetComponent<CharacterController>();
}
void Update()
{
Vector3 direction= new Vector3(0, 0, 1);
Vector3 velocity= direction * speed;
if (player.isGrounded == true)
{
if (Input.GetKeyDown(KeyCode.Space))
{
yVelocity = jumpHeight;
}
}
else
{
yVelocity -= gravity;
}
velocity.y = yVelocity;
player.Move(velocity * Time.deltaTime);
}
}
I tried Rigidbody & much more script but my player doesn't jump if my player jump then my doesn't move left or right sometimes my player stocked in ground.. tell me the right way of script where I can use

For the left/right movements you can try this simple code :
using UnityEngine;
public class PlayerMove : MonoBehaviour
{
public float speed;
private float yVelocity;
public CharacterController player;
public float jumpForce = 10.0f;
public float moveForce = 5.0f;
public float gravity = 1.0f;
private void Start()
{
player = GetComponent<CharacterController>();
}
void Update()
{
Vector3 direction = new Vector3(0, 0, 1);
Vector3 velocity = direction * speed;
// Add left/right movement
if (Input.GetKey(KeyCode.LeftArrow))
{
velocity += Vector3.left * moveForce;
}
else if (Input.GetKey(KeyCode.RightArrow))
{
velocity += Vector3.right * moveForce;
}
if (player.isGrounded)
{
if (Input.GetKeyDown(KeyCode.Space))
{
yVelocity = jumpForce;
}
}
else
{
yVelocity -= gravity;
}
velocity.y = yVelocity;
player.Move(velocity * Time.deltaTime);
}
}

How to control the curve of a jump mechanic in Unity while using the Rigidbody2D's velocity?

I'm making a platformer controller using the new Input System and trying to control the curve for jumping... I've figured out how to add a damp for the horizontal movement which give the horizonal movement a bit of a slippery feel. But I cannot figure out how to control curve for the Jump. The problem now is I'm using a Player Input Component and Unity Events to control the Move and Jump. And the jump is using rb.velocity.y.
How do I control my Jump curve?
Here is the current curve:
I want to controle the acceleration and deacceleration of the curve:
Here is the curve I'd like to achieve with jumping

Moving an object towards a position not working properly

I have written a code to get a random transform from my list pathPoints and move my object based on that transform, but what it is doing is getting multiple transforms and trying to move everywhere at once. I want the object to move at one position then get a new position and move there then repeat.
Here is the code:-
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PathFinder : MonoBehaviour
[SerializeField] List<Transform> pathPoints;
[SerializeField] Transform pathPrefab;
[SerializeField] float moveSpeed = 10f;
[SerializeField] bool isMoving = false;
[SerializeField] bool isH_Attacking = false;
Animator anim;
Transform defaultWayPoint;
Transform currentTargetPoint;
void Awake()
{
anim = GetComponent<Animator>();
defaultWayPoint = pathPrefab.GetChild(0);
}
void Start()
{
currentTargetPoint = pathPoints[Random.Range(0, pathPoints.Count)];
transform.position = defaultWayPoint.position;
}
void MoveToNextWayPoint()
{
if(transform.position != currentTargetPoint.position)
{
float delta = moveSpeed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position, currentTargetPoint.position, delta);
anim.SetBool("isMoving", true);
isMoving = true;
}
GetNextWayPoint();
}
Transform GetNextWayPoint()
{
currentTargetPoint = pathPoints[Random.Range(0, pathPoints.Count)];
Debug.Log(currentTargetPoint.position);
return currentTargetPoint;
}
void Update()
{
MoveToNextWayPoint();
}
*The script is attached to the gameObject which I want to move.
*This is a 2d project.

void MoveToNextWayPoint()
{
if(transform.position != currentTargetPoint.position)
{
float delta = moveSpeed * Time.deltaTime;
transform.position = Vector3.MoveTowards(transform.position, currentTargetPoint.position, delta);
anim.SetBool("isMoving", true);
isMoving = true;
}
else
{
GetNextWayPoint();
}
}

On Line Renderer will Instantiate GameObject to make a bridge (Unity c#)

I am trying to make a bridge using Line Renderer.
With this script i write on mouse click straight line and when i want somehow use
"startPos" and "endPos" to make that streched gameobject (sprite renderer)
in 2d game.. how to write down Instatiate function? I am lost in this..
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DrawBridge : MonoBehaviour
{
private LineRenderer lineRend;
private Vector2 mousePos;
private Vector2 startMousePos;
[SerializeField]
private SpriteRenderer spriteRender;
private float distance;
[SerializeField]
GameObject spawnBridge;
private void Start()
{
lineRend = GetComponent<LineRenderer>();
lineRend.positionCount = 2;
spriteRender = GetComponent<SpriteRenderer>();
}
private void Update()
{
if (Input.GetMouseButtonDown(0))
{
startMousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
}
if (Input.GetMouseButton(0))
{
StartDrawn();
}
}
void StartDrawn()
{
mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector3 startPos = new Vector3(startMousePos.x, startMousePos.y, 0f);
lineRend.SetPosition(0, startPos);
Vector3 endPos = new Vector3(mousePos.x, mousePos.y, 0f);
lineRend.SetPosition(1, endPos);
distance = (mousePos - startMousePos).magnitude;
// Instantiate(spawnBridge, startPos, endPos, transform.rotation.);
}
}
