Changing inventory item label

placydplacyd
in Technical Q&A

Is there a way to change the label of an inventory item during gameplay? I am looking for a similar action like Rename Hotspot, but I could not find anything for the inventory.

    Not without scripting - unlike Hotspots, inventory data is stored in asset files.

    The easiest way around this is to create a second instance of the item - i.e. same graphic - but with a different label. You can then swap one for the other using the Inventory: Add or remove Action's "Replace" option, giving the effect of its name being changed.

    Thanks! I was thinking about the same solution you mentioned, but I was curious if there is another way.

    I just wanted to check if having multiple items is still the preferred way to do this?

    It would be nice with something similar to hotspot.SetName("new label", lineId) if possible. But I guess the way they are stored might make this difficult.

    Thanks

    Changing the name directly would involve updating the raw asset data, which I don't recommend.

    Technically, it is possible - right-click the item's Label (if not name) field label to get an API reference to it that can be set at runtime. Such a change will persist upon exiting Play Mode, however.

    Swapping the item out for another is the safer approach.

    Hi Chris, I was able to make it work by using Inventory: Add or remove for this feature. However, since I am also using OnInventoryAdd to make a menu popup everytime a new item is added to the inventory, the menu keeps popping up whenever the empty bottle is added back. Anyway to work around this? Thanks in advance.

    Since the time of my last writing, it's now possible to override an item's label via the ItemLabel property.

    Example usage:

    InvInstance invInstance = KickStarter.runtimeInventory.PlayerInvCollection.GetFirstInstance ("MyItem");
invInstance.ItemLabel = "My new label";

    I assume it's similar to change the graphic?

  • ChrisIceBoxChrisIceBox

    Yes.

    Hi Chris, I am still struggling with it since I am not a programmer.
    Is it ok if you can give me an example of the script? 🥲

  • ChrisIceBoxChrisIceBox 
    using UnityEngine;
using AC;

public class ChangeItemData : MonoBehaviour
{

    public string itemName = "Bottle";
    public Texture2D bottleTexture;
    public Texture2D, emptyBottleTexture;

    public void ChangeToFullBottle ()
    {
        ChangeItem (itemName, "Bottle", bottleTexture);
    }

    public void ChangeToEmptyBottle ()
    {
        ChangeItem (itemName, "Empty bottle", emptyBottleTexture);
    }

    public void ChangeItem (string itemName, string newLabel, Texture2D newTexture)
    {
        InvInstance invInstance = KickStarter.runtimeInventory.PlayerInvCollection.GetFirstInstance (itemName);
        invInstance.ItemLabel = newLabel;
        invInstance.Tex = newTexture;
    }

}

    To use it, attach to an empty GameObject, make a prefab, remove from the scene, and assign the textures in its Inpsector.

    Then, use the Object: Call event Action, reference the prefab, and invoke either the ChangeItemData component's ChangeToFullBottle or ChangeToEmptyBottle functions (I'm guessing the intent here).

    I think I am doing something wrong as I cannot see those functions, or maybe I am looking at the wrong place?

  • centuryeggyocenturyeggyo

    Maybe is because of these errors?

  • centuryeggyocenturyeggyo

    oh I fixed the errors.

  • centuryeggyocenturyeggyo

    Yay it worked. Thank you so much Chris. You the best! 😀

  • centuryeggyocenturyeggyo

    @ChrisIceBox , is there a way to make this survive scene change and saving?

  • ChrisIceBoxChrisIceBox

    I'm afraid not - at least not automatically. You would need to keep track of these changes via a separate script, and then apply them back to the items upon loading.

    A tutorial on saving custom global data can be found here.

  • centuryeggyocenturyeggyo

    Understood. Thanks for letting me know.
