 * @author Mokusei Penguin

 * @help [version 2.0]
 * This plugin is for RPG Maker MZ.
 * 
 * ▼ Overview
 *  - By making the battle log display method cumulative, sentences will not
 *    disappear immediately even if the log progresses quickly.
 *  - You can check the battle past log from the party command.
 * 
 * ▼ Log Type
 *  〇 all
 *   - The battle log window disappears after a certain amount of time has
 *     passed since the last log was displayed.
 *  〇 1-line
 *   - The logs are deleted in order from the log that has passed a certain
 *     period of time since it was displayed.

/*:ja
 * @target MZ
 * @plugindesc 戦闘ログの表示方法や動作を変更し、戦闘の進行を早くします。
 * @author 木星ペンギン

 *
 * @help [version 2.0]
 * このプラグインはRPGツクールMZ用です。
 * 
 * ▼ 概要
 *  - 戦闘ログの表示方法を蓄積型にすることで、ログ進行が早くても文章がすぐに
 *    消えることがなくなります。
 *  - パーティコマンドから戦闘過去ログを確認することができます。
 * 
 * ▼ ログタイプ
 *  〇 まとめて消去
 *   - 最後のログが表示されてから一定時間がたつと戦闘ログウィンドウが
 *     非表示となります。
 *  〇 一行ずつ消去
 *   - 表示されてから一定時間経過したログから順に消去されます。
