Guess wrong? It sinks into the floor. No pressure. 😅

Blueprint based sorting in #unrealengine for any type array is hard. However, in a lot of use cases, you can use bucket sort, which is what I did to sort the learning items in @cuprum2929.vaslabs.io
Each item has an order integer >= 0 which is used to index in a prefilled array
