 /*:
 * @plugindesc v1.06 Enable specified maps to memorize the locations of
 * events when leaving and loading them upon reentering map.
 * @author Yanfly Engine Plugins
 *
 * @help
 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * Normally in RPG Maker MV, leaving a map and returning to it will reset the
 * map positions of all the events. For certain types of maps, such as puzzles,
 * you would want the map to retain their locations.
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * Map Notetag:
 *   <Save Event Locations>
 *   This will cause the map to save every event's location on that map. After
 *   leaving and returning to that map, the events will be reloaded onto their
 *   last saved positions in addition to the direction they were facing.
 *
 * Event Notetag:
 *   <Save Event Location>
 *   This will enable this specific event to save its location on this map.
 *   After leaving and returning to the map, the event will be reloaded onto
 *   its last saved position in addition to the direction it was facing.
 *
 * If you wish to reset the position of the Event, simply use the Event Editor
 * and use "Set Event Location" to anchor the event's location to the desired
 * point as if you would normally.
 *
 * ============================================================================
 * Plugin Commands
 * ============================================================================
 *
 * Plugin Command
 *   ResetAllEventLocations
 *   - This resets all the event locations on the map.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.06:
 * - Fixed an issue where using an event to instantly move an event would not
 * save the event's location.
 *
 * Version 1.05:
 * - Fixed a bug where if an event whose location is to be saved starts with a
 * direction other than down, the direction would be overwritten when loaded.
 *
 * Version 1.04:
 * - Updated the <Save Event Location> to save an event's direction even if it
 * didn't move.
 *
 * Version 1.03:
 * - Fixed a bug where reset locations would not save properly.
 *
 * Version 1.02:
 * - Fixed a bug where battles would reset saved location notetags.
 *
 * Version 1.01:
 * - Fixed an incompatibility with the Set Event Location event command.
 *
 * Version 1.00:
 * - Finished plugin!
