Hi KJ,
I've tried to display space left for 2 slots items in inventory (because we can have a max "tetris" situation where there's space for 30 1 slot items but none for a 2 slot item), the idea is : but there is no way to get Hud.Inventory.GetItemRect(Item) or Hud.Inventory.InventoryItemsUiElement.Rectangle I would use to calculate that when the inventory is not open.
I don't know if Hud.Game.InventorySpaceUsed is calculated or is it data from game but a Hud.Game.InventorySpaceLeftForTwoSlotItems or a way to get item slot position in inventory when it's not open would be great.
