 *
 * 戦闘の背景を使用して、雰囲気を作ることができます。
 * 例えば、森の中を歩いている時、敵に遭遇した場合、
 * 背景にかわいいうさぎや木が見えると、森のような気分になります。
 *
 * しかし、背後に死んだうさぎと枯れた木が見えると、かなり違う印象になります。
 * 敵がうさぎと木を全て戦闘中に死なせる呪文を唱えるとどうなりますか?
 *
 * RPGツクールMVには、戦闘背景を変更できるイベントコマンドがあります。
 *
 * しかし、戦闘中に戦闘背景を変更しようとすると、
 * 何も起こらないことに気づくでしょう。
 *
 * 代わりに、変更は次の戦闘で反映されます。
 * このプラグインを使用すると、戦闘中に背景を変更できます。
 *
 * == 使用法 ==
 *
 * 戦闘中、イベントコマンドの3番目のページにある'戦闘背景の変更'を使用します。
 *
 * 戦闘背景がすぐに変更されます。
 * 変更は現在の戦闘でのみ持続し、戦闘が終了すると元に戻ります。
 *
 * -- 戦闘背景の保存と復元 --
 *
 * 戦闘背景を変更する必要があり、変更する前の状態に戻したい場合があります。
 *
 * このプラグインは、現在の戦闘背景を保存して復元する機能を提供します。
 *
 * 戦闘背景を保存するには、下記のスクリプトを使用します。
 *
 *   BattleManager.saveBattlebacks()
 *
 * 戦闘背景を復元するには、下記のスクリプトを使用します。
 *
 *   BattleManager.restoreBattlebacks()

* @plugindesc v1.1 Allows you to change battle background images during battle.
* @help 
* == Description ==
* 
* Video: https://www.youtube.com/watch?v=KHA6yRAMhMk
* 
* Battle backgrounds can be used to provide some sense of atmosphere.
* For example, if you're walking through a forest and you encounter an enemy,
* seeing some cute bunnies and trees in the background makes it feel like a
* forest.
* 
* However, if you see dead bunnies and dying trees in the background, it feels
* much different. What happens if an enemy can cast a spell that will cause all
* of those bunnies and trees to die during battle?
* 
* RPG Maker MV comes with an event command that allows you to change battlebacks.
* However, if you try to change battlebacks during battle, you'll notice that
* nothing happens.
* 
* Instead, the change will only appear in the next battle.
* This plugin allows you to change battle backgrounds during battle.
* 
* == Terms of Use ==

* == Change Log ==
* 
* 1.1 - Apr 19, 2016
*  * Implemented support for saving and loading battlebacks
* 1.0 - Nov 22, 2015
*  * initial release
* 
* == Usage ==
* 
* During battle, use the "Change Battleback" event command located on the 
* third page of the event commands.
* 
* This will change the battleback immediately.
* The changes will only last for the current battle, and will revert after
* the battle finishes.
* 
* -- Saving and Restoring Battlebacks --
* 
* There may be situations where you want to change the battleback, and you
* want to restore it to what it was before you changed it, but you didn't
* know what the battlebacks were because they could have been anything at
* that point.
* 
* This plugin provides functionality for saving the current battlebacks and
* then restoring them.
* 
* To save battlebacks, use the script call
* 
*   BattleManager.saveBattlebacks()
* 
* To restore battlebacks, use the script call
* 
*   BattleManager.restoreBattlebacks()
*
