What's the best way to store Item Data?

Unity Engine

Hi,
Im currently making a 2D weapon customizer where
you can click on a button and then a weapon with random parts will be spawned.
Each Weapon has a stock,barrel,body and grip (I have made multiple of every category).
Now I want to save all Weaponparts in a Database so i can access them from everywhere but I dont know how.

Thx for helping :slight_smile:

using System.Collections.Generic;
using UnityEngine;

public class CustomizedWeapon
{
    public int stock;
    public int barrel;
    public int body;
    public int grip;
}

public class MyScript : MonoBehaviour
{
    public GameObject m_stock;
    public GameObject m_barrel;
    public GameObject m_body;
    public GameObject m_grip;

    public List<GameObject> stocks = new List<GameObject>();
    public List<GameObject> barrels = new List<GameObject>();
    public List<GameObject> bodys = new List<GameObject>();
    public List<GameObject> grips = new List<GameObject>();
    CustomizedWeapon m_customizedWeapon;

    // When the player has chosen a randomly generated weapon, you call this method to store the weapon data.
    public void SaveCustomizedWeapon(int i_stock, int i_barrel, int i_body, int i_grip)
    {
        CustomizedWeapon customizedWeapon = new CustomizedWeapon { stock = i_stock, barrel = i_barrel, body = i_body, grip = i_grip };

        PlayerPrefs.SetString("customizedWeapon", JsonUtility.ToJson(customizedWeapon));
        PlayerPrefs.Save();
    }

    // When you want to load the customized weapon, you call this method to retrieve the data
    public void LoadCustomizedWeapon()
    {
        m_customizedWeapon = JsonUtility.FromJson<CustomizedWeapon>(PlayerPrefs.GetString("customizedWeapon"));

        // Now you can rebuild the weapon from the data
        m_stock = stocks[m_customizedWeapon.stock];
        m_barrel = barrels[m_customizedWeapon.barrel];
        m_body = bodys[m_customizedWeapon.body];
        m_grip = grips[m_customizedWeapon.grip];
    }
}

You should post your code (of how you generate the weapon) because now it’s kinda hard to help you.
As you can see I populate public GameObject fields according to the data from the CustomizedWeapon class because I do not know what your setup is, but hopefully this can help you, if anything is not clear, I’ll be happy to explain more in-depth after you post your code.

Edit: fixed copy/paste error where m_barrel, m_body and m_grip would all be set from the stocks List.

Thank you, very nice example. Easy to read.

The JsonUtiilty part is something I don’t have any experience with but I’ll look into the subject when I get there.:slight_smile:
