Inventory & Equipment

Saving and loading the inventory and equipped items.

Saving

There are 4 things that require saving here: items, enchantments (applied to items), equipment, and currencies. You can use Inventool.CreateSavableData to get an object that contains all of this data. This method will return a InventoolSavableData struct.

InventoolSavableData mySavableData = Inventool.CreateSavableData();

Loading

Use Inventool.SetData and provide a InventoolSavableData object as the parameter to load data. This will set the inventory items, equipment, and currencies.

When setting data, no events are invoked. So, for equipment, it may be necessary for you to manually check which items the player has equipped (and enable/disable any necessary GameObjects based on that).

Inventool.SetData(mySavableData);

Examples

The code below is how you can save and load Inventool's data with ESave. ESave is my own save system—it's entirely free, and it's been tested with Inventool. ESave is not a requirement; you can use the save system of your choice. However, the example below will only work with ESave.

With ESave Free

using Esper.ESave;
using Esper.Inventool;
using Esper.Inventool.DataManagement;
using UnityEngine;

public class InventoolSavingExample : MonoBehaviour
{
    /// <summary>
    /// The ID used to save and load the data.
    /// </summary>
    private const string dataID = "Inventool";

    /// <summary>
    /// The save file.
    /// </summary>
    private SaveFile saveFile;

    private void Start()
    {
        saveFile = GetComponent<SaveFileSetup>().saveFile;

        // Load the data on start
        Load();
    }

    private void OnApplicationQuit()
    {
        // Save when exited play mode or the game
        Save();
    }

    /// <summary>
    /// Saves Inventool data.
    /// </summary>
    private void Save()
    {
        var savableData = Inventool.CreateSavableData();
        saveFile.AddOrUpdateData(dataID, savableData);
        saveFile.Save();
    }

    /// <summary>
    /// Loads Inventool data if it exists.
    /// </summary>
    private void Load()
    {
        if (saveFile.HasData(dataID))
        {
            var savableData = saveFile.GetData<InventoolSavableData>(dataID);
            Inventool.SetData(savableData);
        }
    }
}

With ESave Pro

In case you're using the pro version...

using Esper.ESave;
using Esper.Inventool;
using Esper.Inventool.DataManagement;
using UnityEngine;

public class InventoolSavingExample : MonoBehaviour
{
    /// <summary>
    /// The ID used to save and load the data.
    /// </summary>
    private const string dataID = "Inventool";

    /// <summary>
    /// The save state.
    /// </summary>
    private SaveState saveState;

    private void Start()
    {
        // Initialize ESave (if not already done)
        ESave.Initialize();
        
        if (!ESave.HasSave(0))
        {
            // Create a save if it doesn't exist
            ESave.CreateSave(0).OnComplete(saveState =>
            {
                this.saveState = saveState;
            });
        }
        else
        {
            // Load the save if it exists
            ESave.Load(0).OnComplete(saveState =>
            {
                this.saveState = saveState;

                // Load the inventory
                Load();
            });
        }
    }

    private void OnApplicationQuit()
    {
        // Save when exited play mode or the game
        Save();
    }

    /// <summary>
    /// Saves Inventool data.
    /// </summary>
    private void Save()
    {
        // Create savable inventory data
        var savableData = Inventool.CreateSavableData();

        // Add to save
        saveState.AddData(dataID, savableData).OnComplete(success =>
        {
            // Save the state
            ESave.Save(saveState);
        });
    }

    /// <summary>
    /// Loads Inventool data if it exists.
    /// </summary>
    private void Load()
    {
        if (saveState.HasData(dataID))
        {
            // Get the inventory data
            saveState.GetData<InventoolSavableData>(dataID).OnComplete(savableData =>
            {
                // Set to inventory
                Inventool.SetData(savableData);
            }); 
        }
    }
}
