pygame/pythonでスプライトを別のものに移動させるにはどうすればいいですか

Question

私はこの質問についてかなりの研究をしてきましたが、私はまだ私の解決のために他の人のソリューションを実装できませんでした。私はMob2クラスをPlayerクラスに移動しようとしています。私のコードへの提案、またはコードの改善方法についても大変感謝しています:)私は以下に書いたコードはAtomで作成されています。本当にありがとうございました！

Answer 1

まず、それが上下に移動する必要があるかどうかを確認するためにrect.yと同じことを行う、その後、左または右に移動する必要があるかどうかを確認するためにPlayer.rect.xでMob.rect.xを比較します。そのモブを単にその方向に動かすこと。
