speechbubble.swf

Displays a floating speech bubble for NPC or contextual dialogue. Trove draws this 600 × 480 surface in the world at the speaker, aiming the bottom centre of the surface at whoever is speaking, which is why the bubble is anchored to the bottom-centre of the stage. The bubble fades in and out on demand with a short alpha tween and redraws itself procedurally to fit the current text.

Document/main class: SpeechBubble (extends MovieClip) SWF-specific classes: 2

Main class: SpeechBubble

Owns the two IggyTween instances that handle fade-in and fade-out, and exposes setText and show as ExternalInterface callbacks for the game engine. Because it extends MovieClip rather than UIComponent, the screen registers none of the UIComponent.* callbacks — setText and show are the whole inbound list. In non-Iggy (preview) mode it self-populates with test text. After every text change or tween completion, it requests a redraw via ExternalInterface.call("RequestRedraw") / ExternalInterface.call("TweenComplete") using a deferred Event.RENDER listener so the engine can composite the frame.

Public methods

  • setText(param1:String, param2:uint) : void — sets bubble.text and bubble.textColor, then calls recenterBubble() and schedules a RequestRedraw on the next render event.
  • show(param1:Boolean) : void — starts the appropriate fade tween (in or out). Guards against re-triggering an already-playing tween or a no-op alpha state; the engine calls show repeatedly with the same value.

Key fields

  • bubble : MovieClip — the embedded Bubble symbol instance; holds the text field and drawn shape.
  • fadeInTween : IggyTween — tweens alpha from 0 to 1 over TWEEN_TIME (0.2 s); motionFinishCallback → tweenComplete.
  • fadeOutTween : IggyTween — tweens alpha from 1 to 0 over TWEEN_TIME (0.2 s); motionFinishCallback → tweenComplete.
  • TWEEN_TIME : Number (const 0.2) — duration of both fade tweens in seconds.

Runtime dependencies & integration

  • IggyFunctions.inIggy — branch guard; ExternalInterface callbacks are only registered when running inside the Iggy runtime.
  • ExternalInterface callbacks registered: setText, show.
  • ExternalInterface calls made: RequestRedraw (after text change and after tween finishes), TweenComplete (after fade tween finishes, to signal the engine).
  • Events: Event.RENDER used as a deferred one-shot hook after text/tween changes; listener is always removed after firing.

Notable logic

  • recenterBubble() positions bubble so it is horizontally centered and bottom-aligned to the stage: x = (stageWidth - bubble.bubbleContainer.width) / 2, y = stageHeight - bubble.bubbleContainer.height.
  • show() cross-stops the opposite tween before starting the requested one, preventing simultaneous fade conflicts.

Other game-specific classes

Bubble

A self-drawing speech-bubble component extending MovieClip. Embeds symbol symbol4 from /_assets/assets.swf.

Contains bubbleContainer : MovieClip (holds the procedurally drawn shape) and textField : TextField.

Shape constants — CORNER_WIDTH 30, CORNER_HEIGHT 20, STEM_WIDTH 38, STEM_HEIGHT 34, EDGE_MIN 4, WIDTH_MIN 98, HEIGHT_MIN 40.

When text is set, recalculateSize() expands the text field to fit content (respecting minimums), chooses CENTER alignment for single-line text and LEFT for multi-line, then calls drawBubble(w, h). drawBubble clears and redraws a rounded-rectangle with a downward stem using graphics.curveTo / lineTo on a Shape added to bubbleContainer. The fill is near-opaque black (0, alpha 0.9) with a 3-px white outline.

Properties: text : String (get/set via textField.htmlText), textColor : uint (get/set via textField.textColor).

Notable logic

  • The bubble shape is entirely procedural — no bitmaps.
  • The file's DefineFont3 "Open Sans Semibold" has an empty glyph table (a font reference; the game supplies the glyphs), and its ImportAssets2 from SharedLibraryController imports no assets. The 24 btn_console_* icons placed by class name inside the Bubble sprite therefore resolve to nothing — dead placements beside bubbleContainer and textField. Rounded corners are drawn with curveTo, the stem is a triangle protruding from the bottom edge, offset to appear center-left of the bubble bottom.
  • Text alignment is dynamic: single-line text is centered; multi-line wraps left-aligned.
  • bubbleContainer.numChildren == 0 guard ensures bubbleShape is only added once; subsequent drawBubble calls just clear and re-draw the same Shape.
