cのポインタと構造体？

Question

ここは新しいです。 私はテキストベースのゲームを書いていますが、ここには何かがありません。私がそれを実行すると、コマンドがすべてスイッチアップされ、私は何かを解放したりリセットしたりするのを忘れていると思うが、どこか何か分からない。 私は新入生ですから、間違いはおそらく皆さんにとって恐ろしいことです。私は助けていただきありがとうございます！ :)

あなたは "コマンドがアップ切り替える取得" 以外のすべての問題を見ていますか？ない場合は、問題があるかもしれない：

shuttle_door->eastDoor=cpt_qtr; shuttle_door->southDoor=NULL; shuttle_door->eastDoor=bridge; shuttle_door->northDoor=escape_shuttle;

あなたは二回eastDoorを割り当てることを意味していましたか？
