/*:
 * @plugindesc v1.02 - Utiliza regiões para teleportar o jogador.
 *
 * @author Dr.Xamã
 *
 * @help
 * ================================================================================
 *    Introdução
 * ================================================================================
 * Você coloca a região no mapa e depois teleporta o jogador para ele, bem simples.
 * ================================================================================
 *    Comandos de Plugin e Script
 * ================================================================================
 * - createTeleportToRegion mapId regionId
 *   - Exemplo: createTeleportToRegion 1 2
 *
 * - teleportToRegion mapId direction fade
 *   - direction: 2, 4, 6, 8 // 2 = Baixo, 4 = Esquerda, 6 = Direita e 8 = Cima
 *   - fade: 0 ou 1 // 0 = Preto e 1 = Branco
 *   - Exemplo: teleportToRegion 1 2 0
 *
 * - $gameTemp.createTeleportToRegion(mapId, regionId);
 * - $gameTemp.teleportToRegion(mapId, direction, fade);
 * - $gameTemp.getRegionXy(mapId, Xy);
 *   - Xy: 'X', 'Y' ou nada
 *   - Exemplo: $gameTemp.getRegionXy(1, 'X'); // Pega o TileX
 *   - Exemplo: $gameTemp.getRegionXy(1, 'Y'); // Pega o TileY
 *   - Exemplo: $gameTemp.getRegionXy(1); // Pega ambos os tiles em um array,
 *              elemento 0 = X e 1 = Y
 * ================================================================================
 *    Informações
 * ================================================================================
 * Esse plugin faz parte do projeto "RPG MAKER MV + Javascript" do Dr.Xamã.
