draghost.swf

A lightweight drag-image host used in Trove's inventory or item UI. When the player begins dragging an item, the engine pushes a texture name to this SWF; it renders the texture as a Bitmap that follows the cursor, acting as the drag ghost/phantom image.

Document/main class: DragHost (extends KiwiComponent) SWF-specific classes: 1

Main class: DragHost

Minimal single-responsibility class. On config() it adds a Bitmap child to the display list and registers one ExternalInterface callback. The engine drives all state through that callback.

Public methods / overrides

  • (none beyond constructor)

Key fields

  • image : Bitmap — the bitmap display object that shows the dragged item's texture. Created at field-init time (new Bitmap()); added to the display list in config().

Runtime dependencies & integration

  • ExternalInterface callback registered: DRAGHOST.SETTEXTURENAME(param1:String) — receives a texture name string from the engine.
  • IggyFunctions.setTextureForBitmap(bitmap, name) — Iggy runtime call that populates image with the named texture. This is the only operation performed when the callback fires; there is no additional layout or transform logic.

Notable logic

  • The entire functional surface is a single Iggy API call: setTextureForBitmap. Positioning of the SWF itself (following the mouse cursor) is handled entirely by the game engine — this class only manages which texture is displayed.
  • No hide/show, no alpha tweening, no size adjustment — the SWF is likely toggled visible/invisible or repositioned externally.
  • Extends KiwiComponent for constraint/layout infrastructure, but none of those features appear to be used here.
