 /*:
 * @plugindesc v1.02 Allows events to trigger by being in specific regions
 * instead of needing to exactly next to or on top of them.
 * @author Yanfly Engine Plugins
 *
 * @help
 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * In RPG Maker MV, events can only trigger when you are either standing next
 * to them or on top of them. This plugin lets you bind their activation to
 * different events onto regions, making them trigger if the player is standing
 * on the designated region first before talking to them through the Action
 * Button, Player Touch, Event Touch, Autorun, and/or Parallels giving them
 * multitudes of ways to trigger events. All of these can be done by simply
 * adding Comment Tags into an event's page.
 *
 * This is different from Region Events, which causes a Common Event to autorun
 * once the player has stepped onto one of those regions. This plugin binds
 * actual map events to regions instead.
 *
 * ============================================================================
 * Comment Tags
 * ============================================================================
 *
 * By default, event pages have no Region Triggers. They have to be added
 * manually per event page using comment tags. You can use the following
 * comment tags to give each event page a region trigger.
 *
 * ---
 *
 * Comment Tags:
 *
 *   <Region Trigger: x>
 *   <Region Triggers: x, x, x>
 *   - Replace 'x' with the ID's of the regions you wish to let the event
 *   trigger if the player is standing within a tile with that region ID and
 *   triggering the event page's activation trigger requirements.
 *
 * ---
 *
  * Event region triggers behave differently depending on the event page's
 * trigger type. Here is how the event page will activate based on the trigger:
 *
 *   Action Button
 *   - As long as the player is within the matching region ID, pressing
 *   the OK button will activate the event.
 *
 *   Player Touch
 *   - If the player moves within the matching region ID, the event will
 *   automatically activate. The player can also press the OK button to trigger
 *   the event.
 *
 *   Event Touch
 *   - If the player moves within the matching region ID, the event will
 *   automatically activate. The player can also press the OK button to trigger
 *   the event.
 *
 *   Autorun
 *   - If the player moves within the matching region ID, the event will
 *   automatically activate. There is no escaping this autorun unless you have
 *   a way of turning it off.
 *
 *   Parallel
 *   - If the player moves within the matching region ID, the event will
 *   automatically activate. The player is granted a few frames of movement
 *   each time the parallel process loops.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.02:
 * - Fixed a bug where parallels don't loop.
 *
 * Version 1.01:
 * - Fixed a bug where Autorun and Parallel triggers won't run unless they had
 * a region associated with them.
 *
 * Version 1.00:
 * - Finished Plugin!
