# ・歩行グラフィック、ピクチャ、バトラーにブログgifのようなエフェクトを追加し
#   ます。
#==============================================================================
=begin
・歩行グラフィック
イベントコマンドの移動ルートの設定にて、
    start_rainbow(0〜119の数字)
と記入すると対象が虹色に変色します。()のなかの数字は変色開始時のいろと関係して
いて、同じ番号は同じ色から始まります。
終了するときは
    end_rainbow
と記入してください

・ピクチャ
イベントコマンド、バトルイベントで
    start_rainbow(ピクチャ番号,0〜119の数字)
と記入するとピクチャ番号と同じ番号のピクチャが虹色に変色します。
0〜119の数字は変色開始時のいろと関係していて、同じ番号は同じ色から始まります。
終了するときは
    end_rainbow(ピクチャ番号)
と記入するとピクチャ番号と同じ番号のピクチャの色が元に戻ります。

・バトラー
バトルイベントで
    start_rainbow_b(対象の敵グループ内の番号,0〜119の数字)
と記入すると同じ番号のバトラーが虹色に変色します。敵グループ内の番号とは
イベントコマンドの「敵キャラのＨＰの増減」等で指定するときの番号のことです。
0〜119の数字は変色開始時のいろと関係していて、同じ番号は同じ色から始まります。
終了するときは
    end_rainbow_b(対象の敵グループ内の番号)
と記入すると同じ番号のバトラーの色が元に戻ります。
