オセロ作りました
時間がないからコードで埋めた記事
作った作品
皆さんこんにちは。ハニワです。今回の新入生歓迎イベントではDynamicOthelloという作品を作りました。 本当は通信を実装してオンラインで対戦できるようにしたかったのですが能力と時間が足りず結果対面でしかできない作品となってしまいました。
実装について
プログラミングやっている人向けの話になるのですがオセロのプログラムを組んだことはありますか？ 組むとしたら裏返しや設置判定はどのような方法と実装したでしょうか？ for分を使って実装すれば良いと思う人もいるかと思いますが僕は今回そこら辺の判定は再帰を用いて実装しました。 コード汚いのですが興味がある人は下にコードを載せておくので参考にして下さい。 再帰使った関数は下の方にあります。

再帰とか実装系は競技プログラミングで練習するのがおすすめです！（布教）
最後に
やっぱりオンライン機能を実装できなかったのが心残りなので、次の作品ではオンライン機能に再挑戦します。 最後までご閲覧ありがとうございました。
