注意
本記事で掲載されている動作の実装方法及びプログラムのソースコードは最適な方法ではない可能性があります。今後不具合等が判明した場合には修正及び改良をおこなう可能性があります。
また今後自分で同機能を実装する場合の参考にする可能性もあるためソースコードだけではなく説明しつつ記事を進めていきます。
Unityによる自作ゲーム開発進捗その３１になります！
今回は近接攻撃システムを実装しました。
攻撃判定の仕組みは直線攻撃する仕様と大きく違いはありませんが、キャラクターのアニメーションに合わせた判定を付ける必要があります。
既存のスクリプトを２つ更新します。
以下に動画でのコピー用にソースコードを掲載しています。

}直接攻撃の判定はコルーチンを使用してコライダーやエフェクトの切り替えをおこなっています。
配列の偶数ループ時に当たり判定やエフェクトを出すようにして奇数時には消すという仕組みで作成してみました。
現在は動作確認用に１つの近接攻撃しか実装していませんが、【配列の時間配分】に加えて【コライダーの大きさ調整配列】【TAGの変更配列】等もループ内容に加える事で多種多様な近接攻撃を実装出来る見込みです。
