Question by Lastered · May 31, 2021 at 02:14 PM · gameobjectinstantiate

Why can't I use a prefab in the GameObject slot?

Hi, I'm new to Unity and game developing entirely so I'm sorry for any misunderstandings I may cause. While working on a top down dungeon crawler project I noticed that when using my wepon.cs script I could not select a prefab as the gameObject to Instantiate. Instead, I can only select a gameObject from the hierarchy. I couldn't find anyone with the same issue or a solution to it so any help will be greatly appreciated.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class wepon : MonoBehaviour
 {
     public GameObject bulletPrefab;
 
     public Transform firePoint;
     [SerializeField]
     private float shootReady = 1;
     [SerializeField]
     private float bulletsPerMag = 8;
     [SerializeField]
     private float bullets;
     [SerializeField]
     private float reloadTime = 3;
     [SerializeField]
     private float reloading = 0f;
 
     [SerializeField]
     private Color noAmmo = Color.white;
     [SerializeField]
     private Color hasAmmo = Color.white;
     private Renderer rend;
 
     void Start()
     {
         rend = GetComponent<Renderer>();
     }

     void Update()
     {
         if (bullets >= 1)
         {
             rend.material.color = hasAmmo;
         }
         else
         {
             rend.material.color = noAmmo;
         }
         if (Input.GetKeyDown(KeyCode.Mouse0))
         {
             if (shootReady == 1 && bullets >= 1)
             {
                 bullets = bullets - 1;
                 Shoot();
             }
         }
 
         if (bullets <= 0 && reloading == 0)
         {
             reloading = 1;
             shootReady = 0;
             Invoke("reload", reloadTime);
         }
     }
 
     void Shoot()
     {
         Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
     }
 
     void reload()
     {
         reloading = 0;
         shootReady = 1;
         bullets = bulletsPerMag;
     }
 }
