小粒プログラミング 牌山

#04 牌山から配牌を取る(1)

Javascriptで遊ぶ麻雀小粒プログラミング 今回のお題は、生成した牌山から配牌を取る処理を紹介します。配列の頭から順番に牌を引いていくだけの簡単な処理です。



プログラムの解説と実行

第一回目のお題の牌山を生成するで作った牌山から配牌を取り出します。今回は単純に牌山の配列（yama）の0番地から順番に牌を取り出します。

▲配列の牌山(yama)から配牌を取るイメージ（一番目の牌山）

内部処理では牌山の上下は関係ありません。配列から順番に抜き出していくだけです。見せ方を考慮すると、上山の1番目が0番地、下山の1番目が1番地になるなど、上下が交互に入れ替わります。ややこしいですね。実際に牌山をグラフィック表示させる場合は、そのための処理を実装する必要があるかもしれません。
