info.swf

The Trove info-message feed in the bottom-left corner of the screen that displays timed one-line notifications (item pickups, experience gains, system notifications) in a stack. Messages auto-expire after 8 seconds and fade out over 0.5 seconds before being reaped. Supports a reduced capacity mode for Nintendo Switch (NX).

Document/main class: Info (extends _kiwi.Core.UIComponent) SWF-specific classes: 3

Main class: Info

Info is the root document class. It holds a single child infoLog:InfoLog and acts as the Iggy entry point. Its only job is to register the ADD_MESSAGE callback and route messages to the correct InfoLog method depending on platform.

Key fields

Field Type Role
infoLog InfoLog The scrolling message log component; the only root child (chid 4), placed at (0, 214) on the 425×219 stage, so rows stacked at negative y grow up from the bottom-left corner

Runtime dependencies & integration

ExternalInterface.addCallback:

  • ADD_MESSAGE(channel, author, message, color) → routes to infoLog.onInfoMessageNX(0, channel, message, author, color) on NX (IsNX()), otherwise infoLog.onInfoMessage(...) with the same arguments. This is the screen's whole engine surface: there are no outbound calls.

Other game-specific classes

InfoLog (embeds /_assets/assets.swf#symbol4)

Extends com.kiwi.Core.KiwiComponent. Manages two arrays (_renderers, _pendingRenderers) and a 100 ms reaper Timer. All rendering happens inside a Sprite child named container.

Constants:

  • MaxMessages = 9 — maximum visible messages (PC/default).
  • MaxMessagesNX = 5 — maximum visible messages on NX.
  • MessageDuration = 8000 ms — time before a message begins fading.

Key methods:

  • onInfoMessage(index, channel, message, author, color) — creates an InfoItemRenderer, sets its expireTime and reapTime, adds it to container and _pendingRenderers, enforces MaxMessages by trimming the oldest entry if over the limit, then calls validateNow().
  • onInfoMessageNX(...) — identical but calls renderer.ConfigNX() first and enforces MaxMessagesNX.
  • draw() — flushes _pendingRenderers into _renderers, then lays out all renderers stacked upward (newest at bottom, oldest at top): iterates renderers in reverse, accumulating negative Y offsets so the list grows upward.
  • onReaperTimerComplete(TimerEvent) — fires every 100 ms; removes renderers whose reapTime has passed (calls stopFadeOut() and removes from container), and calls startFadeOut() on renderers past their expireTime.
  • enforceMessageLimit(count, max) — shifts and removes the oldest renderer from _renderers until within the limit.

Timer: _reaperTimer = new Timer(100) started in config().

InfoItemRenderer (embeds /_assets/assets.swf#symbol3)

Extends com.kiwi.Templates.KiwiButton, implements com.kiwi.Interfaces.IListItemRenderer. Renders a single info message line.

Static constants:

  • s_fadeOutSeconds = 0.5 — fade duration in seconds.
  • s_format — TextFormat("Comfortaa", 14, white, bold) for PC.
  • s_formatNX — TextFormat("Comfortaa", 20, white, bold) for NX (larger text).

Key fields:

  • primaryText : TextField — the visible message text.
  • expireTime : Number — Unix ms timestamp when the message starts fading.
  • reapTime : Number — Unix ms timestamp when the renderer is removed (expireTime + 500).
  • _fadeOut : IggyTween — tween driving the alpha fade (uses IggyTween with fl.transitions.easing.None.easeOut).

Key methods:

  • setData(obj) — sets _color, then sets primaryText.text via formatMessage(channel, author, message) (which currently just returns message, ignoring channel/author). config() applies _color as the text colour, so each line is painted in the colour the engine sent.
  • ConfigNX() — switches primaryText.defaultTextFormat to s_formatNX.
  • height (override) — returns primaryText.textHeight so the log layout uses actual rendered text height.
  • startFadeOut() — creates an IggyTween animating alpha from 1 → 0 over 0.5 s.
  • stopFadeOut() — stops and nulls the tween.

IggyTween usage: new IggyTween(this, "alpha", None.easeOut, 1, 0, s_fadeOutSeconds, true) — the true final argument likely auto-starts the tween.

Notable logic

  • Messages are stacked upward: draw() iterates _renderers from last to first, subtracting each renderer's height from a running Y offset and assigning it as renderer.y. This means newer messages appear at the bottom.
  • The reaper loop runs every 100 ms (not frame-rate dependent), giving consistent message lifetime regardless of frame rate.
  • formatMessage is a static stub that ignores channel and author, displaying only the raw message string. The engine sends message as the finished, localised line — a pickup, for example, is $ItemPickupEvent ("You got {0} {1} {2}") already filled in with the count and item name.
  • NX path enforces both a smaller display cap (5 vs 9) and a larger font size (20 vs 14).
