Livery Editor – History

Thin wrapper around the dynamic decals API undo/redo system that notifies the UI on history changes.

Thin wrapper around the dynamic decals API undo/redo system that notifies the UI on history changes.

Overview

ui_liveryEditor_history exposes undo and redo operations and listens for layer mutations (add, delete, update, move) to push history state to the UI via guihooks.

Extension path: lua/ge/extensions/ui/liveryEditor/history.lua

Exports (M)

FunctionSignatureDescription
undo()Undoes the last operation via api.undo().
redo()Redoes the last undone operation via api.redo().

Hook Listeners

These are called by the dynamic decals API - do not call directly.

HookTrigger
dynamicDecals_onLayerAdded(layerUid)A layer was added
dynamicDecals_onLayerDeleted(layerUid)A layer was deleted
dynamicDecals_onLayerUpdated(layerUid)A layer property changed
dynamicDecals_moveLayer(from, fromParentUid, to, toParentUid)A layer was reordered

All four hooks trigger guihooks.trigger("LiveryEditor_onHistoryUpdated", api.getHistory()).

How It Works

  1. User performs an action (add/delete/move/update layer)
  2. The dynamic decals API fires one of the dynamicDecals_* hooks
  3. This module catches the hook and pushes the full history object to the UI
  4. The UI updates its undo/redo button states accordingly

Example Usage

-- Undo last action
extensions.ui_liveryEditor_history.undo()

-- Redo
extensions.ui_liveryEditor_history.redo()
