わかりましたので、コードを実行しています。現在、ユーザーが右または左を保持しているときにプレーヤーが壁に衝突すると、プレーヤーは壁をゆっくりと滑り落ち、プレーヤーが方向 (左または右) を放すと、プレーヤーは続行します。普通に落ちる。
私がやりたいことは、プレイヤーが壁にぶつかったときに壁に「くっつく」ようにすることです。つまり、彼はまだ滑り落ち、地面にぶつかるまで滑り落ちます (ユーザーは方向を保持する必要はありません)ユーザーは壁から飛び降りることができます。（それをプレイしたり、ゲームプレイやロックマンを見たりした人にとっては、スーパーミートボーイだと思います）。誰かがこれにアプローチする良い方法を提案できますか?
