Inventory offset

Zinph

Hi, I'm making a 2D game with the direct movement method using a keyboard.

I have an inventory with 5 slots. I set 2 buttons to offset it 1 slot at a time. Let's say I have 10 items. When the first time I open the inventory, it'll show the first 5 items. If I offset it forward 3 times, for example, it'll now show the items #4-8. When I turn the inventory off and then turn it on again, it's still offset and shows the items #4-8. Is it possible to make it show the first 5 items like the first time I opened it?

Thanks a lot!

Yes - though you'll need a custom script to do so, as it involves calling the InventoryBox element's ResetOffset function as the Menu turns on.

This should do it:

using UnityEngine;
using AC;

public class RestInventoryOffset : MonoBehaviour
{

    public string menuName = "Inventory";
    public string elementName = "Items";

    void OnEnable () { EventManager.OnMenuTurnOn += OnMenuTurnOn; }
    void OnDisable () { EventManager.OnMenuTurnOn -= OnMenuTurnOn; }

    void OnMenuTurnOn (Menu _menu, bool isInstant)
    {
        if (_menu.title == menuName)
        {
            (_menu.GetElementWithName (elementName) as MenuInventoryBox).ResetOffset ();
        }
    }

}

Hi, I can't figure out how to make it work. Could you point out where I'm doing wrong?

I added the script to a gameobject prefab

I used Object: Send message in the Actionlist when turn on the Inventory to call the function. I tried to use it in other places but it didn't work either.

Here is my Inventory setup.

I also changed the menu name in the script to match the menu.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using AC;

public class RestInventoryOffset : MonoBehaviour
{

    public string menuName = "Inventory";
    public string elementName = "InventoryBox";

    void OnEnable() { EventManager.OnMenuTurnOn += OnMenuTurnOn; }
    void OnDisable() { EventManager.OnMenuTurnOn -= OnMenuTurnOn; }

    void OnMenuTurnOn(Menu _menu, bool isInstant)
    {
        if (_menu.title == menuName)
        {
            (_menu.GetElementWithName(elementName) as MenuInventoryBox).ResetOffset();
        }
    }

}

Here is the video test

The script is self-contained: it hooks into the OnMenuTurnOn custom event, which kicks in automatically. You don't need to use Object: Send message.

The component in your screenshot isn't enabled, however - make sure it's enabled and present in the scene, and it should work.

I put the script in the Persistent Engine prefab and it works. Thanks a lot for the help, Chris!
