私と私の友人は、Stackoverflow はコードに関する質問をする場所だと言われました。:)
私たちは、Objective-C、Xcode、および Cocos2d にかなり慣れていないため、知識を深めるために簡単なタスクを完了しようとしています。
以下のコードを見ると、Ant オブジェクトが作成され、Ant オブジェクトが画面に配置されています。ここで、タッチ位置を使用して、ユーザーがタッチした位置にアリを移動させたいと考えています。
それを行う正しい方法が何であるかはわかりません。現時点では、クラスの作成から離れているため、すべてのコードを 1 か所にまとめていますが、画面上のアリをタッチ位置に移動させる方法がわかりません。
誰でも助けることができますか？
