Inventory Showcases

Requires every Crimson plugin

CrimsonCore is free to download, but compiles only with all Crimson plugins installed. Every showcase actor and item definition named below ships in CrimsonCore's own content - you place them in a level of your own.

Build an InventoryShowcase station in a level of your own out of the shipped actors: sixteen B_CrimsonItemSpawnerPads (/CrimsonCore/GameplayTesting/, one per shipped item definition), the containers (B_Chest_Shared, B_Stash_Personal, the one-time B_LootChest, the player-owned B_OwnedStash), a pre-filled B_LootBag, and B_ItemVendingMachine (every item definition in stock, refilled as you take) - the containers, bag, and machine all live in /CrimsonCore/Inventory/Actors/. For locked doors gated by interaction conditions (keys, a lockpick, Health at or above 50), see Doors -> Build a door showcase. Walk over a pad to receive its item, open the inventory, and try each feature below. The pads cool down (CooldownSeconds) and refill.

Showcase content

Asset	Path (`/CrimsonCore/Inventory/`)	Notes
`ItemDef_Apple`, `ItemDef_HealthPotion`, `ItemDef_ManaPotion`	`Items/`	Stackable consumables (`Item.Type.Consumable`); consumable tooltip.
`ItemDef_IronSword`, `ItemDef_RustySword`, `ItemDef_IronHelm`, `ItemDef_Shield`, `ItemDef_Boots`, `ItemDef_GoldRing`, `ItemDef_SilverRing`	`Items/`	Equippable (`UCrimsonInventoryItemFragment_Equippable`). `ItemDef_RustySword` carries `UCrimsonInventoryStateFragment_Durability`.
`ItemDef_Satchel`, `ItemDef_GridPouch`	`Items/`	Bags (`UCrimsonInventoryItemFragment_Bag`). Both only contribute once dragged into one of the player's two bag slots (the `Bags` strip; `Crimson.Inventory.Constraint.BagSlots = 2` on the GFA). Grid Pouch = `Mode: SeparatePanel`, `Layouts/DA_InvLayout_Grid` 4 x 2 - its own panel. Satchel = `Mode: ExpandRoot`, `Slots` 4 - no panel, the main grid grows 24 -> 28 while it is slotted. A slotted bag refuses to leave while it holds items.
`ItemDef_IronOre`	`Items/`	Stackable material (`Item.Type.Material`).
`ItemDef_Torch`	`Items/`	`UCrimsonInventoryStateFragment_Lifetime` (`TotalLifetime`) - it burns down.
`ItemDef_GoldCoins`, `ItemDef_Gem`	`Items/`	`UCrimsonInventoryItemFragment_GrantCurrency` (`Item.Type.Currency`) - picking them up adds to `Currency.Gold` / `Currency.Gems` instead of taking a slot.
`T_Item_*`	`Items/Icons/`	One icon per item definition.
`DA_CrimsonInventoryLayout_FlatSlot`	(root)	Flat slot layout used by the player inventory, the chests, and the Satchel.
`DA_InvLayout_Grid`, `DA_InvLayout_Weight`	`Layouts/`	Grid layout (used by the Grid Pouch) and weight layout (shipped as a reference; no showcase pad uses it).
`DT_Currencies`	(root)	`Currency.Gold`, `Currency.Gems`. Registered by `CrimsonGameFeatureAction_AddInventory`.
`EquipDef_IronSword`, `EquipDef_Shield`, `EquipDef_IronHelm`, `EquipDef_Boots`, `EquipDef_Ring`	`Equipment/`	CrimsonEquipment definitions the equippable items reference.
`ItemTypeActionSet_Core`	(root)	Context actions per `Item.Type.` (Use, Equip, Split, Drop, ...) - see Context Menu*.
`B_Chest_Shared`, `B_Stash_Personal`, `B_LootChest`, `B_OwnedStash`, `B_ItemVendingMachine`, `B_LootBag`	`Actors/`	12-slot shared and personal containers, the one-time loot chest, the player-owned stash, the vending machine, and the loot bag. The plugin's `PerParty` / `PerMapInstance` scopes have no showcase (per-run storage, not persisted).

Tag labels (Equipment.Slot.*, Item.Type.*, Crimson.Inventory.Constraint.*, Currency.*) come from [/Script/CrimsonUI.CrimsonTagLabelSettings] in the project's Config/DefaultGame.ini; UCrimsonCoreInventoryUIStatics::GetTagLabel reads them for tab names, meter labels, and paper-doll labels.

Showcase matrix

Showcase	Plugin pieces	Try it with
Flat slot list	`UCrimsonInventoryLayout_FlatSlot` -> `UCrimsonCoreInventoryGroupPanel` (Flat) with `W_Inventory_Slot` per cell	The player inventory: `DA_CrimsonInventoryLayout_FlatSlot`, 24 slots from `CrimsonGameFeatureAction_AddInventory`.
Grid with rotation	`UCrimsonInventoryLayout_Grid` -> group panel (Grid): `Grid_Cells` + `Canvas_Items` overlays, Rotate verb, `bSupportsRotation`	Pick up `ItemDef_GridPouch`, open it, drop `ItemDef_IronSword` inside and press RT / R while carrying.
Weight list	`UCrimsonInventoryLayout_Weight` -> group panel (Weight): `Box_List` + `Meter_Capacity`	`Layouts/DA_InvLayout_Weight` - assign it as a bag or inventory layout; no pad is wired to it.
Shared chest	`ACrimsonCoreContainerActor` (`Scope = Shared`) + `W_Container_Screen`	`B_Chest_Shared` - everyone sees the same contents.
Personal stash	`Scope = PerPlayer`	`B_Stash_Personal` - each player has a private instance.
Party and map-instance chests	`Scope = PerParty`, `Scope = PerMapInstance`	No showcase asset: these scopes are per-run storage (`UCrimsonInventoryInstanceSubsystem`), not persisted. Duplicate `B_Chest_Shared` and set `Scope` to try one.
Loot bag	`ACrimsonCorePickupActor` + `W_Loot_Window` + `W_Loot_Entry`	The placed `B_LootBag`.
Nested bags	`UCrimsonInventoryItemFragment_Bag` -> child `UCrimsonCoreInventoryGroupViewModel` (`ParentGroupId`, `Depth`) rendered as its own group panel	`ItemDef_Satchel` (flat, 4) and `ItemDef_GridPouch` (grid, 4 x 2).
Paper doll	`UCrimsonCoreEquipmentPanel` + `W_Equipment_Slot` per `Equipment.Slot.*` via `ICrimsonEquipmentHost`	Carry `ItemDef_IronHelm` onto the Head slot; double-click `ItemDef_Boots`.
Hotbar drag	`UCrimsonCoreInventoryDragDropOperation` (a `UCrimsonSlotBindingDragDropOperation`) dropped on `W_ActionBar`	Drag `ItemDef_HealthPotion` from the inventory onto an action-bar slot - see Radial Slot Bindings.
Currency, HUD, toasts	`UCrimsonInventoryItemFragment_GrantCurrency`, `W_Inventory_HUD` at `HUD.Slot.Inventory`, `W_Inventory_Toast` at `HUD.Slot.Toasts`	Walk over `ItemDef_GoldCoins` / `ItemDef_Gem`: the HUD currency row updates and a toast shows.
Sort, filter, search, lock	`UCrimsonCoreInventoryPanelWidget` (`SearchBox`, `TabList_Categories` from `CategoryTags`, `Button_Sort`), Lock verb	Collect a mix, type "potion", switch tabs, press Sort, lock a sword and try to drop it.
Split and context menu	Split verb -> `W_SplitStack_Dialog`; Secondary -> `UCrimsonCoreContextMenuSubsystem` with `ItemTypeActionSet_Core`	Stack five `ItemDef_Apple`, press X (hold) / X to split; right-click for the menu, X (tap) for the default action.
Tooltips per kind	`TooltipClassByItemType` -> `W_ItemTooltip_Consumable` / `_Equipment` / `_Bag`, `W_ItemTooltip` fallback	Focus a potion, a sword, a bag, and `ItemDef_IronOre` in turn.
Durability and lifetime	`Durability01` -> `Bar_Durability` on slot, paper doll, and tooltip; `UCrimsonInventoryStateFragment_Lifetime`	`ItemDef_RustySword` shows a durability bar; `ItemDef_Torch` counts down.

How the showcase is wired

Piece	Asset	Key settings
Player inventory + routing	Your experience action set -> `CrimsonGameFeatureAction_AddInventory`	`InventoryList[0]`: `B_CrimsonPlayerState` (`/CrimsonCore/Player/`), `DA_CrimsonInventoryLayout_FlatSlot`, `Crimson.Inventory.Constraint.Slots = 24`, `RuntimeConstraints = [CrimsonInventoryConstraint_Slot]`, `DT_Currencies`. `RoutingList[0]`: `B_PlayerController` (`/CrimsonCore/Player/`).
Equipment slots	Your experience action set -> `CrimsonGameFeatureAction_AddEquipmentSlots`	`SlotsList[0]`: `BP_CrimsonCharacter` (`/CrimsonCore/Characters/`), `SlotLayout` for Head / Chest / Legs / Feet / MainHand / OffHand / Ring, `bAddEquipmentManager = true`.
HUD strip + toasts	Your experience action set -> `CrimsonGameFeatureAction_AddWidget`	`W_Inventory_HUD` at `HUD.Slot.Inventory`; `W_Inventory_Toast` at `HUD.Slot.Toasts`.
Inventory screen	`GA_ShowWidget_Inventory` (`/CrimsonCore/Input/Abilities/`)	Pushes `W_Inventory_Screen` on `UI.Layer.Menu`.
Screen verbs	`W_Inventory_Screen`, `W_Container_Screen`, `W_Loot_Window` Class Defaults	`Input\|Verbs` entries point at `IA_UI_Inventory_*`; keys in `IMC_UI_Inventory`.
Tooltips and split dialog	`Plugins/CrimsonCore/Config/DefaultCrimsonCore.ini`	`UCrimsonCoreInventoryUISettings` defaults (see Inventory UI).
Item pads	`B_CrimsonItemSpawnerPad` (`/CrimsonCore/GameplayTesting/`)	`ItemToGrant`, `StackCount`, `CooldownSeconds`; `bIsAvailable` replicates so the `DisplayMesh` hides during cooldown - see Gameplay Testing.
Weight overflow -> movement slow	A `CrimsonInventoryConstraint_FloatTag` child with `bAllowOverflow`, a `CrimsonCoreConstraintActionSet` asset, and the `ConstraintActions` component on `B_CrimsonPlayerState` (`/CrimsonCore/Player/`)	`CrimsonGameFeatureAction_AddInventory`: `DefaultFloatConstraints = [Crimson.Inventory.Constraint.Weight, 50]`, `RuntimeConstraints +=` your overflow constraint. The action set binds that tag to Apply Gameplay Effect While Over Threshold (`SetByCallerTag = SetByCaller.Encumbrance.Overflow`, `SetByCallerScale = -0.5`). Nothing ships pre-wired - see How-To: Constraint Actions.

Build your own station

Place B_CrimsonItemSpawnerPad actors and set ItemToGrant to each definition you want to demo (StackCount 5 for the consumables so Split has something to split). Drop in a duplicate of each chest Blueprint and a B_LootBag. Make sure the level runs an experience whose action set includes the CrimsonGameFeatureAction_AddInventory, CrimsonGameFeatureAction_AddEquipmentSlots, and CrimsonGameFeatureAction_AddWidget entries above.

Verify (Play As Client)

Two players, Play As Client. Both collect from the pads (each pad refills after CooldownSeconds), one fills B_Chest_Shared, the other sees it; each fills B_Stash_Personal and sees only their own.
