One inventory but different item categories.

Hello,

Inventory questions are often asked, but not as much as I thought it would be. Not to mention there are a lot of different kinds of inventory system.

My question is: if I have several categories of item (with different variables), all herited from one Main_Item_BP, what would be the best way to still have a single inventory array and still getting acces to the specific variables from those categories?

I’ve tried to registrer the Main_Item_BP, but I can’t get access to the variable. In my inventory, I’ve tried to put a general structure that would change depending on the item type, but that’s impossible. I’ve tried to work on the Main_Item_Class, but I can just access the main variable and, anyway, I cannot work with the proper references to the items.

So I’ve even tried to still keep the class and then to work with datatables and putting the RowName in the Inventory_Struct, so I could loop and run through the datatable and find the good item… But it was quite a mess.

So yeah, just wondering what’s the best way to implement it.

Thanks.

I don’t think there’s a ‘best’ way, but this looks pretty good. Uses a BP hierarchy and makes things ‘inventorisable’ using a component:
