please help

the code:

using System.Collections.Generic;
using UnityEngine;

public class DocumentManager : MonoBehaviour
{
    [Header("Assign document prefabs (different ID cards, etc.)")]
    public GameObject[] documentPrefabs;

    [Header("Parent for spawned docs (optional)")]
    public Transform container;

    [Header("How many to spawn (will clamp to number of prefabs)")]
    public int spawnCount = 3;

    // Keep references so we don't spawn duplicates
    private readonly List spawned = new List();

    // Call this when character reaches center
    public void ShowDocuments()
    {
        if (spawned.Count > 0) return; // already spawned
        if (documentPrefabs == null || documentPrefabs.Length == 0) return;

        Camera cam = Camera.main;
        if (cam == null)
        {
            Debug.LogError("No main camera found.");
            return;
        }

        // center world point — using a z that is the same plane as your docs (0)
        Vector3 screenCenter = new Vector3(Screen.width / 2f, Screen.height / 2f, Mathf.Abs(cam.transform.position.z));
        Vector3 worldCenter = cam.ScreenToWorldPoint(screenCenter);
        worldCenter.z = 0f;

        // choose how wide the documents spread (units)
        float spread = 1.2f;
        int toSpawn = Mathf.Clamp(spawnCount, 1, documentPrefabs.Length);

        // spawn evenly around center
        int midIndex = toSpawn / 2;
        for (int i = 0; i < toSpawn; i++)
        {
            int prefabIndex = i % documentPrefabs.Length;
            Vector3 pos = worldCenter + new Vector3((i - midIndex) * spread, 0f, 0f);
            GameObject prefab = documentPrefabs[prefabIndex];
            GameObject go = Instantiate(prefab, pos, Quaternion.identity, container);
            spawned.Add(go);
        }
    }

    // Removes and destroys spawned documents
    public void ClearDocuments()
    {
        foreach (var g in spawned) if (g != null) Destroy(g);
        spawned.Clear();
    }

    // Convenience: spawn from inspector
#if UNITY_EDITOR
    [UnityEditor.MenuItem("Tools/SpawnDocs_Debug")]
    private static void DebugSpawn() { }
#endif
