よし、基本的なゲームを作った。キャラクターを左右に動かし (a と d を使用)、ジャンプさせた。私が今やろうとしているのは、生成された地形によってキャラクターがその上で停止できるようにすることです。たとえば、キャラクターがジャンプした場合、ブロックに触れるとブロックの上で止まります。私が本当に必要としているのは、全体を書き直すことではなく、すでに書いたコードでうまく機能するいくつかの基本的なコードです。また、補足として、多くの人が KeyListener の代わりに KeyBindings を使用すると言っていますが、KeyListener は、私がこのコーディングを処理する方法ではるかにうまく機能します。ご協力いただきありがとうございます！
