INTERACTION_CONTROLLER

const INTERACTION_CONTROLLER: "$interaction" = '$interaction'

Defined in: ui/controller/ui-controller.ts:48

The built-in controller name driven by pointer state (normal/hover/pressed/ disabled). An entity that carries a $interaction controller + Interactable gets its button states through gears — the one mechanism for all widget interaction visuals (color/sprite/scale, or any other reflected field).
