Livery Editor - Controls

Action map management for the livery editor - handles input mode switching between transform, rotate, scale, and stamp modes.

Overview

ui_liveryEditor_controls manages input action maps for different livery editing modes. It switches between cursor-based and mouse-projection-based input and provides toggles for vehicle and edit-mode action maps.

Constants

Internals

Action Map Registry

local ACTION_MAPS = {
  rotate = "LiveryEditorRotate",
  scale = "LiveryEditorScale",
  skew = "LiveryEditorSkew",
  transform = "LiveryEditorTransform",
  transformStamp = "LiveryEditorTransformStamp",
  material = "LiveryEditorMaterial"
}

Mode Switching

useActionMap disables all action maps first, then activates the requested one. If the API is in mouse-position mode, transform is automatically upgraded to transformStamp:

M.useActionMap = function(actionMapKey)
  disableAllActionMaps()
  actionMapKey = actionMapKey == "transform" and api.isUseMousePos() and "transformStamp" or actionMapKey
  local actionMap = ACTION_MAPS[actionMapKey]
  if actionMap then
    pushActionMap(actionMap)
  end
end

Input Modes

Vehicle Control Override

During editing, vehicle controls are disabled to prevent accidental input:

M.enableVehicleControls = function(enable)
  scenetree.findObject("VehicleCommonActionMap"):setEnabled(enable)
  scenetree.findObject("VehicleSpecificActionMap"):setEnabled(enable)
end

How It Works

1. Livery editor starts → disableAllActionMaps() clears input state
2. Edit mode activates → useActionMap("transform") pushes appropriate map
3. User toggles mouse projection → liveryEditor_OnUseMousePosChanged switches mode
4. Mode change auto-selects transform vs transformStamp action map
5. On deactivation, all livery action maps are popped and vehicle controls restored
