How do I equip Weapons in 2d side scroller

Question

I am trying to figure out how to equip weapons in my 2d side scroller game. I want to be able to click on an icon in my inventory and have that be my weapon. Right now I have the animation working but I cant figure out how to swap out the weapon for another. Should my weapons be sprites or prefabs. Below is my Inventory script. If you need any other info let me know. Im at a complete loss and couldnt find anything useful online the last week. Thanks

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class Inventory : MonoBehaviour {
 
     public static Inventory inventory;
 
     private bool paused = false;

     public WeaponClassScript.WeaponCreaterClass currentWeapon = null;
 
 
     private Rect inventoryWindowRect = new Rect(300,100,410,410);
     
     //private Dictionary
     public Dictionary<int,Texture2D> inventoryNameDictionary = new Dictionary<int, Texture2D> ();
 
     void Awake()
     {    
         inventory = this;
 
         inventoryNameDictionary.Add (0, null);
         inventoryNameDictionary.Add (1, null);
         inventoryNameDictionary.Add (2, null);

If you have a prefab of the object, here's what you do:

Create a folder in the root of your project called "Resources".
Put whatever prefab you want to 'equip' in the "Resources" folder.
In code, you can use the instantiate function to instantiate it. The prefab is in the "Resources" folder so you can access it with the Resources.Load() function.

So if I had a "Resources" folder with a prefab named "pizza" inside it, I could make a new one assigned to the variable selector like this:

GameObject selector = Instantiate(Resources.Load("pizza")) as GameObject;

Whatever you want to instantiate goes in place of "pizza", so if you had subfolders in the "Resources" folder, you could do that too. So If you have a subfolder, "Foods" inside the "Resources" folder and the pizza prefab was in the "Foods" folder, you would do:

GameObject selector = Instantiate(Resources.Load("Foods/pizza")) as GameObject;

Hope this helps!

Almost, It is instantiating the image which is great but it is just coming up at origin when I click on it in my inventory. Not to my gameobject I want it attached to.
