Re: Save System Question ;)
Posted: Mon May 16, 2022 9:22 am
I started adding the changes to my own saver script as recommended...
However, I'm not quite certain how to "hook" the GetItemFromID from its current location to this one...
Its in a script file called InventoryItem.cs (here is its FULL content unedited)
so there is a "public static InventoryItem GetFromID(string itemID)"
I replaced your line :
GetItemFromID(string itemID)
with this :
pickup.item = InventoryItem.GetFromID(data.itemID);
However, now i'm getting a weird error in the data section at the top : (see screenshot)
