/*:
 * @plugindesc This plugin change title scene.
 * @author Tsumio
 *
 *
 * @param CommandImage
 * @type file[]
 * @require 1
 * @desc This is a setting sets the files for using the command images. You need as many files as the number of commands. (Read from img\tsumio folder)
 * @dir img/tsumio
 * @default
 *
 * @param RotationType
 * @type number
 * @desc This is a setting sets the rotation type.1 = TrueCircle, 2 = Ellipse1, 3 = Ellipse2.Please refer to the help for details of each type.
 * @default 1
 *
 * @param CenterX
 * @type number
 * @desc This is a setting sets X location that is the center of rotation.
 * @default 320
 *
 * @param CenterY
 * @type number
 * @desc This is a setting sets Y location that is the center of rotation.
 * @default 300
 *
 * @param AmountOfRotation
 * @type number
 * @desc This is a setting sets amout of rotation.（120＝120 degrees）
 * @default 120
 *
 * @param CorrectPos
 * @type number
 * @desc This is a setting sets the angle to correct the initial position of the image。(90=90 degrees）
 * @default 90
 *
 * @param Offset
 * @type number
 * @desc This is a setting sets the distance from the center XY. The larger it is, the farther away from the center position.
 * @default 120
 *
 *
 * @help If you introduce this plugin , the title screen is changed.
 * On the screen after change, it is necessary to use the number of images as many as the number of commands.
 * Especially if you do not change, the number of commands is 3 (New Game Contents Option).
 *
 * ----feature----
 * You can realize a title command with using pseudo 3D.Pseudo 3D has depth.
 *
 * ----how to use----
 * After adding this plugin, set each plugin parameter.
 * 'CommandImage' parameter needs images as many as the number of the commands.
 * Especially if you do not change, three images required.
 * Also, add images in the order of the commands on the title screen.
 * In the default case, please add images in the following order.
 * 1.New Game
 * 2.Contents
 * 3.Options
 *
 * ----about rotation type----
 * There are trhee rotation type.
 * 1.TrueCircle
 *  This is not truely 'TrueCircle' but it looks like 'TrueCircle'.
 * 2.Ellipse1
 *  This means vertically long rotation.
 * 3.Ellipse2
 *  This means horizontally long rotation.
 *
 * You should set only number when you set plugin parameter.
 * ex.If you want to set 'TrueCircle', you should set 1。
 *
 * ----about CorrectPos----
 * Depending on the number and size of images, the selected image may be hidden behind.
 * Also, there may be discrepancies between the position of each image and the selected image.
 * 'CorrectPos' parameter can solve those problems.
 *
 * ----about rotation speed----
 * The speed of rotation can not be set from plugin parameter.
 * If you want to change the speed of rotation, change "var speed = 2;" of Scene_Title.prototype.initializePseudo3DData method.
 * However, manipulating this variable may cause problems.
 *
 * ----about images ratio----
 * The ratio of the rotating image can not be set from plugin parameter.
 * If you want to change the ratio of the rotating image, please change the following methods.
 * もしも回転している画像の拡大率を変えたい場合、NTMO.Data_Pseudo3D.prototype.initializeメソッドの
 *
 * "NTMO.Data_Pseudo3D.prototype.initialize" method.
 * this._default_scale   = 0.7;
 * this._range           = 0.3;
 *
 * It looks natural if you add two numbers and make it 1.
 *
 * ----plugin command----
 * There is no plugin command.

/*:ja
 * @plugindesc タイトル画面を変更します。
 * @author ツミオ
 *
 * @param 選択肢の画像
 * @type file[]
 * @require 1
 * @desc 選択肢の画像に使うファイルを設定します。ファイルは選択肢の数だけ必要です。（img\tsumioフォルダから読み込み）
 * @dir img/tsumio
 * @default
 *
 * @param 回転タイプ
 * @type number
 * @desc 回転のタイプを設定します。1 = TrueCircle, 2 = Ellipse1, 3 = Ellipse2。各タイプの詳細はヘルプを参照してください。
 * @default 1
 *
 * @param 回転の中心X座標
 * @type number
 * @desc 回転の中心となるX座標を設定します。
 * @default 320
 *
 * @param 回転の中心Y座標
 * @type number
 * @desc 回転の中心となるY座標を設定します。
 * @default 300
 *
 * @param 回転する量
 * @type number
 * @desc 回転する量を設定します。（120＝120度）
 * @default 120
 *
 * @param 初期位置の補正
 * @type number
 * @desc 画像の初期位置を補正する角度を設定します。(90=90度）
 * @default 90
 *
 * @param オフセット
 * @type number
 * @desc 各画像の中心位置からの距離を設定します。大きければ大きほど中心位置から離れます。
 * @default 120
 *
 * @help このプラグインを導入すると、タイトル画面が変更されます。
 * 変更後の画面では、必ずコマンドの数だけ画像を使用する必要があります。
 * コマンドの数はデフォルトでは3です（ニューゲーム・コンテニュー・オプション）。
 *
 * 【プラグインの特徴】
 * 疑似3Dを用いた奥行きのあるタイトルコマンドを実現できます。
 *
 * 【使用方法】
 * プラグイン導入後、各プラグインパラメーターを設定します。
 * 「タイトル画像」パラメーターには、メニューのコマンド数と同じだけの画像を必ず設定してください（デフォルトのタイトル画面の場合は3つの画像が必要）。
 * また、画像はタイトル画面のコマンド順に追加していってください（デフォルトの場合はニューゲーム→コンテニュー→オプションの順に追加する）。
 *
 * 【回転タイプについて】
 * 回転のタイプは3種類あります。
 * 1.TrueCircle
 *  真円のように見える回転タイプ。
 * 2.Ellipse1
 *  縦に長い円の回転タイプ。
 * 3.Ellipse2
 *  横に長い円の回転タイプ
 *
 * 各タイプをプラグインパラメーターに設定する場合、数字のみを指定します。
 * ex.TrueCircleを設定したいなら「1」を入力。
 *
 * 【初期位置の補正について】
 * 画像の数や大きさによっては、選択されている画像が後ろに隠れてしまう場合があります。
 * 初期位置の補正パラメーターを調整することによって、各画像の位置と、選択されている画像に齟齬が出ないようにします。
 *
 * 【回転の速さについて】
 * 回転の速さはプラグインパラメーターから設定できないようにしています。
 * もしも回転の速さを変えたい場合、Scene_Title.prototype.initializePseudo3DDataメソッドの
 * 「var speed = 2;」
 * を変更してください。
 * ただし、この変数を操作すると不具合が生じる可能性があります。
 *
 * 【画像の拡大率について】
 * 回転している画像の拡大率はプラグインパラメーターから設定できないようにしています。
 * もしも回転している画像の拡大率を変えたい場合、NTMO.Data_Pseudo3D.prototype.initializeメソッドの
 * this._default_scale   = 0.7;
 * this._range           = 0.3;
 * を変更してください。
 * 2つの数値を足して1になるようにすると自然に見えます。
 *
 * 【プラグインコマンド】
 * このプラグインにプラグインコマンドはありません。
 *
 *
 * 利用規約：
 * 作者に無断で改変、再配布が可能で、利用形態（商用、18禁利用等）
 * についても制限はありません。
 * 自由に使用してください。
