ワープできるようにする
これまで作成してきた「パックマン」もどきにはワープトンネルがありませんでした。今回はワープトンネルも機能するようにします。
通路の変更
まずフィールド変数の以下の部分を書き換えます。
row11の文字列をワープトンネルにつながるように変更しています。またトンネルの入り口を「Ｌ」と「Ｒ」にしています。

public partial class Form1 : Form { string row01 = " ┌───┬───┐ ┌───┬───┐ "; string row02 = " │ │ │ │ │ │ "; string row03 = " │ │ │ │ │ │ "; string row04 = " ├───┼─┬─┴─┴─┬─┼───┤ "; string row05 = " │ │ │ │ │ │ "; string row06 = " │ │ │ │ │ │ "; string row07 = " └───┤ └─┐ ┌─┘ ├───┘ "; string row08 = " │ │ │ │ "; string row09 = " │ ┌─┴─┴─┐ │ "; string row10 = " │ │ │ │ "; string row11 = "Ｌ────┼─┤ ├─┼────Ｒ"; // 変更部分 string row12 = " │ │ │ │ "; string row13 = " │ ├─────┤ │ "; string row14 = " │ │ │ │ "; string row15 = " ┌───┼─┴─┐ ┌─┴─┼───┐ "; string row16 = " │ │ │ │ │ │ "; string row17 = " └─┐ ├─┬─┴─┴─┬─┤ ┌─┘ "; string row18 = " │ │ │ │ │ │ "; string row19 = " ┌─┴─┘ └─┐ ┌─┘ └─┴─┐ "; string row20 = " │ │ │ │ "; string row21 = " └───────┴─┴───────┘ "; } |
またワープトンネルの入り口「Ｌ」と「Ｒ」の部分にも通路を描画する必要があります。

CanPacmanMoveDirectメソッドの変更
パックマンが移動できるかどうかを判定するCanPacmanMoveDirectメソッドに対して、ＬとＲの部分に対応する処理を追加しました。

MovePacmanDirectメソッドの変更
パックマンを移動させるMovePacmanDirectメソッドでワープトンネルを通過すると反対側に移動できるようにしました。

モンスターもワープできるようにする
モンスターの動き（いじけ状態も含めて）も同様に対応させる必要があります。
