Livery Editor – Editor (Core)

Core entry point and API interface for the livery editor UI. Manages editor lifecycle (setup, session, save, exit).

Overview

ui_liveryEditor_editor orchestrates the livery editor: initialising the dynamic decals API, toggling vehicle controls, loading/saving skin files, and cleaning up on exit. It acts as the bridge between the UI layer and editor_api_dynamicDecals.

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

Dependencies

editor_api_dynamicDecals, ui_liveryEditor_layers, ui_liveryEditor_layers_decals, ui_liveryEditor_layers_cursor, ui_liveryEditor_camera, ui_liveryEditor_controls, ui_liveryEditor_resources, ui_liveryEditor_selection, ui_liveryEditor_tools, ui_liveryEditor_tools_transform, ui_liveryEditor_editMode

Internals

Vehicle Controls Toggle

local function toggleVehicleControls(enable)
  local commonActionMap = scenetree.findObject("VehicleCommonActionMap")
  if commonActionMap then commonActionMap:setEnabled(enable) end
  local specificActionMap = scenetree.findObject("VehicleSpecificActionMap")
  if specificActionMap then specificActionMap:setEnabled(enable) end
end

Disables driving inputs while the editor is active, re-enables on exit.

Session Flow

1. startEditor() - one-time setup (API, resources, edit mode, action maps)
2. startSession() - either loads a queued file or creates a new stack with a fill layer using the vehicle's paint colour
3. User edits layers via other livery editor extensions
4. save(filename) - exports skin + saves .dynDecals.json
5. applySkin() - optionally applies the skin so it persists after exiting
6. exitEditor() - tears everything down, restores vehicle controls

Save Filename Pattern

Only alphanumeric, dash, and underscore characters are accepted: ^[a-zA-Z0-9_-]+$

How It Works

1. The editor disables vehicle action maps and the API's own update loop on start
2. A fill layer matching the vehicle colour is added as the base when creating new
3. Saving exports the skin via api.exportSkin() and writes a layer stack JSON file
4. On exit without applying, the skin resets to nil (default); with apply, the named skin stays

Example Usage

-- Start the editor
extensions.ui_liveryEditor_editor.startEditor()

-- Load an existing save
extensions.ui_liveryEditor_editor.loadFile("settings/dynamicDecals/mySkin.dynDecals.json")
extensions.ui_liveryEditor_editor.startSession()

-- Save and apply
extensions.ui_liveryEditor_editor.save("mySkin")
extensions.ui_liveryEditor_editor.applySkin()

-- Exit
extensions.ui_liveryEditor_editor.exitEditor()
