 * File: z_obj_tokeidai.c
 * Overlay: ovl_Obj_Tokeidai
 * Description: Components of the Clock Tower. Also used for wall clocks. The specific components are:
 * - ClockFace: The decorated face of the clock that spins every hour.
 * - MinuteRing: The ring around the clock face that spins every two minutes.
 * - ExteriorGear: The two gears on the side of the tower that spin every two minutes.
 * - SunAndMoonPanel: A panel with a sun and moon image that tells whether it is day or night.
 * - Counterweight: The spinning weight on top of the tower that emits a spotlight at night.
 * - StaircaseToRooftop: The staircase to tower's rooftop that opens after midnight on the Final Day.
 * - TerminaFieldWalls: The walls of the Clock Tower visible from Termina Field.
 * - UnusedWall: A single wall of the Clock Tower, unused in the final game.
 *
 * Sometimes, the ClockFace, MinuteRing, and SunAndMoonPanel are treated as a single clock entity.
 * This is called Clock if it applies to both the Clock Tower clock and wall clocks, and
 * TowerClock/WallClock, respectively, if it only applies to one of them.
 *
 * On the midnight of the Final Day, the Clock Tower opens up, and the various pieces of it
 * are moved around. This actor is responsible for managing all of this movement, which is handled
 * via the series of action functions labeled with TowerOpening.
 *
 * All components have at least one of these three actions:
 * - Idle: The "default" action, and for some components the only action.
 *       The component is either completely still, or it's telling the time, depending on the component.
 * - OpenedIdle: The action for certain Clock Tower components after midnight on the Final Day.
 *       The TowerClock, ExteriorGears, and Counterweight no longer tell time and are moved to a different position.
 *       Called "opened" because it corresponds to when the staircase to the tower's rooftop is opened up.
 * - Collapse: The action for certain Clock Tower components when the moon crashes into Termina.
 *       This action is responsible for making the component fall during the moon crash cutscene.
