Saving custom list (inventory items)

[Kosta]

I have a custom list for my inventory items.
Now I don't know how to save and load custom list (items).

I guess it needs something like this?

Code: Select all

void SaveInventory()
    {
        foreach (var i in inventoryItems)
        {
            ES3.Save<ItemManager>("ItemData", i); // I dont think this is good way to sava list ...???
        }
    }

    void LoadInventory()
    {
        inventoryItems.Clear();
        inventoryItems.Add(ES3.Load("ItemData")); // Not working 
        //How to load saved data and put that into list (inventoryItems)?
        
    }

I tried to find a tutorial or solution online but there is nothing about it...

Hi there,

You can find information on saving Lists in the Saving and Loading Arrays and Collections section of the Getting Started guide.

All the best,

Hi,
Thanks for your reply.
I try with that but it not working.

Error: NotSupportedException: ES3Type.type is null when trying to create an ES3Type for System.Collections.Generic.List`1[ItemManager], possibly because the element type is not supported.

Code: Select all

void SaveInventory()
    {
        ES3.Save<List<ItemManager>>("InventoryData", inventoryItems);
    }

    void LoadInventory()
    {
        inventoryItems.Clear();
        if(ES3.KeyExists("InventoryData"))
        {
            inventoryItems = ES3.Load<List<ItemManager>>("InventoryData");
        }
        else
        {
            SaveInventory();
        }
    }

Hi there,

Please could you show me your ItemManager class so I can understand why it is not supported?

All the best,

Code: Select all

using System;
using UnityEngine;

[System.Serializable]
public class ItemManager : IComparable<ItemManager>
{
    public ItemType.category itemCategory;
    public ItemType.type itemType;
    public ItemType.usage itemUsage;
    [Tooltip("How much hp (or any other consume) effect on player status. +10hp or -10hp etc...")]
    public float itemConsumeAmount;
    public Sprite icon;
    public bool stackable = false;
    public int maxStackable = 8;
    [TextArea] public string itemDescription;
    public float itemDurability;
    [TextArea] public string itemContribution;

    public ItemManager(ItemType.category _itemCategory, ItemType.type _itemType, 
    ItemType.usage _itemUsage, Sprite _icon, bool _stackable, int _maxStackable, 
    string _itemDescription, float _itemDurability, string _itemContribution, float _itemConsumeAmount)
    {
        itemCategory = _itemCategory;
        itemType = _itemType;
        itemUsage = _itemUsage;
        icon = _icon;
        stackable = _stackable;
        maxStackable = _maxStackable;
        itemDescription = _itemDescription;
        itemDurability = _itemDurability;
        itemContribution = _itemContribution;
        itemConsumeAmount = _itemConsumeAmount;
    }

    public int CompareTo(ItemManager other)
    {
        if(other == null)
        {
            return 1;
        }

        return 0;
    }
}

Hi there,

Your class needs a parameterless constructor to be serialisable.

See the Supported Types guide for more info: https://docs.moodkie.com/easy-save-3/es ... ted-types/

Thanks a lot!
Empty constructor solves my problem.
