inventory.swf

The player's Inventory window, showing item slots organized across Adventure, Build, Currency, Geode, and Discovery tabs, plus Personal Chest tabs. Supports up to three bag pages with drag-and-drop, slot expansion purchase, and console/NX button-legend overlays.

Document/main class: Inventory (extends _kiwi.Core.UIComponent) SWF-specific classes: 9 (excluding framework, asset wrappers, and _fla/ timeline symbols)

Main class: Inventory

Inventory is the root display object for the Inventory window. It extends UIComponent and manages all slot data, tab navigation, bag pagination, currency/discovery sub-views, and drop targets. On construction it registers three frame scripts (frames 1, 11, 21 for PC / Console / ConsoleLoc layout variants) and hides all optional UI until the game calls initDisplay.

In the Iggy runtime (IggyFunctions.inIggy == true) the constructor-time configUI() registers 34 ExternalInterface callbacks. Outside Iggy (Flash IDE preview) it falls back to a 50-slot demo layout.

Public methods

  • checkForExpansion() : void — Shows bag buttons (0-2), trash button, and footer; ghosts bags that are not yet unlocked based on numBags.
  • toggleExpansion(visible:Boolean) : void — Shows or hides the expansion purchase button row inside the slots clip.
  • showChestTabs(show:Boolean) : void — Toggles visibility of chest tabs 1-6 and sets their numeric labels.
  • setPersonalChest(isPersonal:Boolean) : void — Marks this inventory as a personal chest and shifts the sort button position.
  • showMainTabs(show:Boolean) : void — Toggles the five main-mode tabs (Adventure/Build/Currency/Geode/Discovery).
  • setTextureBaseName(base:String) : void — Sets the render-target base name for all existing slot entries: a slot's icon is <base><absolute slot index>, named after the slot rather than the item in it (a personal chest sends PersonalChest.Thumbnail.slot_).
  • setSlot(slotId:uint, name:String, description:String, quantity:uint, rarity:uint, showQuantity:Boolean, quality:int, flag:Boolean, percent:Number) : void — Writes item data into slotInfo[] and, if the slot is in the currently visible bag page, updates the on-screen Slot widget. slotId is the absolute index across all bags. The stock screen ignores description (a single space when the item has none) and the eighth argument; no argument identifies the item's type.
  • clearSlot(slotId:uint) : void — Resets a slot to empty in both slotInfo[] and the visible Slot.
  • setSlotCount(totalSlots:int, slotsPerBag:int) : void — Resizes the slotInfo array, recalculates numBags, and refreshes the current bag view. The engine sends it every time the window opens.
  • showNewItemNotification(tabName:String, slotId:int, count:int) : void — Makes a "new item" badge visible on the relevant tab and lights up the slot glow. Not registered with addCallback and not called inside the SWF: the engine calls the public method directly. tabName is AdventureInventory, BuildInventory or CurrencyInventory (the clip is newItem<tabName>); count is unused, and the badge writes back the value it read ((n++).toString()), so its number never advances.
  • updateSlotQuantityAttr(slotId, qty, rarity) : void — Live-updates quantity and rarity on a visible slot without a full redraw.
  • switchTab(direction:int) : void — Cycles the active tab by +1/-1; for player inventory cycles the five modes, for chests wraps through 1-6.

Key fields

  • currentMode : String — One of the five MODE_* constants; governs which sub-panel (slots vs. currencyView) is shown.
  • slotInfo : Array — Flat array of plain Objects, one per slot across all bags, used as the backing store for bag-switch rehydration.
  • slotsPerBag : int = 55 — Slots per bag page (overridden by setSlotCount).
  • numSlots / numBags : int — Total slot count and computed bag count.
  • selectedBag : int — Index of the currently displayed bag page.
  • isPlayerInventory : Boolean — Distinguishes player bag from chest windows (affects expansion, bag buttons, tab navigation). Set only by initDisplay, the engine's signal that this window is the player's own inventory.
  • isPersonalChestInventory : Boolean — Set when this instance is showing a personal storage chest.
  • currencyView : CurrencyInventoryView — The Currency/Discovery sub-panel; toggled visible when the matching tab is active.
  • slots : MovieClip — Container for the 55 timeline-placed slot_0 … slot_54 (Slot instances), the expansion buy button and the row overlays lockedSlot1–lockedSlot10.
  • winHeader : WindowHeaderSmall — Window title bar, initialized with title "INVENTORY".
  • sortBtn : LabelButton — Sort-bag button; hidden in currency mode.
  • buttonLegend : MovieClip — Console button-legend overlay; has multiple named frames (Console, ConsoleLoc, Move, NX_handheld, NX_handheld_move).
  • isLeft : Boolean — Whether the inventory is docked left (affects NX button-legend positioning).

Frame scripts / timeline

  • frame 1 (frame1, label PC) — stop(). PC layout (default).
  • frame 11 (frame11, label Console) — stop(), then forces bag buttons and buttonLegend to the "Console" frame.
  • frame 21 (frame21, label ConsoleLoc) — stop(), then forces buttonLegend to the "ConsoleLoc" (localized console) frame.

Runtime dependencies & integration

ExternalInterface callbacks registered (game → Flash): setTextureBaseName, setWindowName, showChestTabs, setPersonalChest, showMainTabs, selectTab, showUnlockPage, hideUnlockPage, clearSlots, setSlot, setCurrencySlot, addCurrencyHeading, currenciesPopulated, clearSlot, initDisplay, updateSlotQuantityAttr, markSlotEquipped, markSlotInUse, setSlotCount, checkForExpansion, setExpansionPrice, showBag, setShowSort, highlightSlot, unhighlightSlot, moveSlotCursor, setCurrencyCategory, switchTab, switchBag, purchaseRow, showLootCollectorDetails, showTrigger, setMoveMode, UIComponent.onStageResized

Inherited from _kiwi and part of the same contract: objectPreviewReady (ObjectPreview; no slot icon resolves without it), DRAGHOST.DROP (SlotDragDropHelper, delivers drops to onDrop), and the clipboard/text-composition callbacks every root UIComponent registers. The engine also calls showNewItemNotification directly, without a registration.

ExternalInterface calls made (Flash → game): INVENTORY.CONFIGURED (slots per row, slots per bag, max bags — console only, sent once the console frame is reached; max bags is 3 for the player inventory, else 0), SetShownSlots(start, end), OnSortBag, OnBuy ("TWC"), OnTabClicked(identifier), POST_SOUND_EVENT (Play_ui_window_tab), INVENTORY.SET_EXPANSION_VISIBLE, DROP_ONTO_BAG, DROP_ONTO_TRASH, INVENTORY.DROP_ONTO_WINDOW, Height (NX height query), BeginTransfer(currencyId) (sent by no other SWF)

Drag-and-drop: SlotDragDropHelper.registerDropCallback(onDrop) registers onDrop as DRAGHOST.DROP(stageX, stageY, sourceEntityId, sourceComponent, sourceSlotId) for items dropped anywhere; hit-tests bag buttons, trash, and individual Slot instances to route to the correct DROP_ONTO_* call.

Tabs: tab identifiers are adventure, build, currency, geode, discovery and chest_1–chest_6, both for the engine's selectTab(identifier) and for OnTabClicked(identifier). An engine-sent selectTab goes through setTab, which echoes OnTabClicked back unless that tab is already selected; the engine answers OnTabClicked by sending that tab's contents. When the engine opens the window on a currency category it sends selectTab("currency") and then setCurrencyCategory(n).

Personal chest pages: the six chest tabs share one container of numSlots (50) slots and one texture base (setTextureBaseName is sent once, with PersonalChest.Thumbnail.slot_), so the render target PersonalChest.Thumbnail.slot_N shows slot N of whichever page the engine filled last. On OnTabClicked("chest_N") the engine sends clearSlots and then setSlot for indices 0–49 for a page that is owned, or showUnlockPage(priceCredits, walletCredits) and no slots for one that is not. showUnlockPage is the only place a page's price is stated and is always about the selected page; hideUnlockPage is also sent while a tab change is in flight.

Placement: the stage is 451×968. The engine places the window by setting the root's x/y — towards the right edge of the display for the player's inventory (it can overhang the edge), towards the left for a personal chest.

translate() keys used: $Inventory_Mode_Adventure, $Inventory_Mode_Build, $Inventory_Mode_Currency, $Inventory_Mode_Geode, $Inventory_Mode_Discovery, $Select_ButtonLegend, $Move_ButtonLegend, $SwitchScreen_ButtonLegend, $LRToggle_ButtonLegend, $CreditsBuy_ButtonLegend, $CubitsBuy_ButtonLegend

Events: MouseEvent.CLICK on tab/bag/sort/expansion; Event.ENTER_FRAME (one-shot, console init); SlotDragDropHelper drop callback.

Platform guards: IsConsole(), IsNX(), _locale (used to pick ConsoleLoc frame for non-EN, non-ZH locales).

Other game-specific classes

  • CurrencyInventoryView — Sub-panel for the Currency and Discovery tabs; embeds symbol145. Manages a SpliceableTileView (currencyList) populated with CurrencyRow and CurrencyHeading rows; three category filter buttons (Crafting / Specialized / Gem); handles drag-start via SlotDragDropHelper, BeginTransfer on right-click, and tooltip show/hide via SLOT.POINTER_ENTER / UIComponent.OnHideTooltip. Calls changeCurrency when a category filter is clicked. Category index 0/1/2 is Crafting/Specialized/Gem for both changeCurrency and the engine's setCurrencyCategory. setCurrencySlot(slotData, id, name, icon, quantity, rarity, moduleText, textColor) keys each row by id (stored as the row's name; it is the string BeginTransfer and the drag carry, where a grid square drags by its render target); a quantity of 0 removes the row and any heading left empty, and in Discovery mode moduleText (the module's level text) replaces the quantity. currenciesPopulated is the engine's end-of-list signal.
  • CurrencyRow — Embed symbol110. A single currency list item: slot (Slot), nameText, quantityText, backgroundUnlocked. Frames: unselected (frame 1) / selected (frame 13).
  • CurrencyHeading — Embed symbol114. Lightweight heading separator row with a titleText field; inserted between currency category groups. Also used as an end-of-list sentinel ("END_OF_LIST").
  • ModuleRow — Embed symbol107. Layout-identical to CurrencyRow but used in Discovery mode (shows module items, non-draggable). Same fields: slot, nameText, quantityText.
  • InventoryRow — Embed symbol115. Bare KiwiComponent asset holding a row of six Slots (slot_0–slot_5); it is the row _kiwi.Controls.BagContainer builds from, and the stock Inventory grid does not use it.
  • UnlockChest — Embed symbol184 (extends UIComponent). Panel shown by showUnlockPage(priceCredits, walletCredits) in place of the slots when the selected personal-chest page has not been bought; pages are bought with Credits. Exposes walletCredits and priceCredits get/set accessors. Buttons: creditsBuyBtn (calls OnBuy("TWC")), addCreditsBtn (calls OnAddCredits). Has PC (frame 1) and Console (frame 11) layouts for the account-balance sub-clip.
  • currencyResourceList — Embed symbol126. A SpliceableTileView with a pre-configured vertical scrollbar; used as the scroll container inside CurrencyInventoryView.

Asset wrappers (not detailed): 24 rarity_frame_*_png bitmap classes, 13 ScrollArrow*/ScrollThumb*/ScrollTrack* skin classes, 3 btn_XBOne_*_png classes, btn_console_* (6 button symbol classes), btnGreenIcon_small, btnSort, btn_bag_* (3× PC + 3× console + 3× placeholder), btn_trash, currency_credits, currency_points, focusRectSkin, dummy.

Inventory_fla timeline symbols (22 classes)

All in package Inventory_fla, all embed symbols from _assets/assets.swf:

  • ButtonLegend_11 — Console button-legend overlay clip; contains buttonSelect, buttonMove, buttonNavigate, trigger, buttonLegendToggle, LB/RB button clips. Frame labels: Console (1), Move (11), ConsoleLoc (21), NX_handheld (31), NX_handheld_move (43).
  • BalancePanel_52 — Account-balance display with credits and addCreditsBtn; two frames PC/Console.
  • expansion_32 — The "buy more slots" button row; contains price TextField and saleTag. Three frames: up/over/down.
  • slotFrame_20 — Per-slot rarity frame overlay; three frames.
  • tabAdventure_57, tabBuild_56, tabButton_58, tabCrafting_60, tabDiscovery_62, tabGeode_61 — Tab button symbols; frame states active/inactive.
  • qualityPips_31, equipped_22, btn_slot_basic_67, btn_slot_gem_69, btn_slot_specialized_68, btn_expansion_plus_33, expansionlocked_35, bannerTop_2, bannerBottom_5, btn_console_adventure_9, btn_console_build_10, triggerLegend_15 — Remaining timeline symbols (labels, decorative banners, slot-type buttons, console shortcut icons).

Notable logic

  • Bag pagination: slotInfo[] stores data for all bags flat. showBag(n) rehydrates the 55 visible Slot instances from the cached data, then calls SetShownSlots so the game backend knows which range is visible. SetShownSlots(start, end) is sent only from initDisplay and a bag change; the engine answers with clearSlots followed by setSlot calls addressed by absolute index within [start, end) of the current tab's inventory, and it honours any range, not just one bag. clearSlots carries no argument: onClear empties the currency list in Currency/Discovery mode and otherwise clears slot indices 0–slotsPerBag-1.
  • Expansion placement: checkExpansionPlacement() positions the buy-row widget directly below the last unlocked slot and shows row-lock overlays (lockedSlot1-lockedSlot10) for rows past numSlots.
  • Drop routing: onDrop callback from SlotDragDropHelper hit-tests bag buttons and trash before iterating slots; fires DROP_ONTO_BAG (last argument: the engine's bag index 0–2), DROP_ONTO_TRASH, or INVENTORY.DROP_ONTO_WINDOW (last argument: the hit slot's data slot index, or -1) with entity-id and component info.
  • Locale-aware console layout: setMoveMode checks available frame labels (Console, ConsoleLoc) and the _locale global to pick the right button-legend frame; NX handheld mode has additional reduced-height variants.
  • New-item glows: showNewItemNotification sets a count badge on the tab clip and enables newSlotItemGlow on the individual slot (slot_<slotId>, except for the currency tab).
