PythonとKivyを使ったアプリ開発のテストとしてバスケットボールのスコア記録アプリを作成してみました。（が、試しに作成しただけのものですので、実際には使えませんので、今後、ちゃんと使えるものを作ります。）
アプリの概要
このアプリは以下の機能を提供します：
- クォーターの選択と追加
- チームおよび選手の選択
- 得点の追加
- スコアのリアルタイム表示
- 直近のスコアの表示
- スコアのリセット
画面イメージ
使用技術
- プログラミング言語: Python
- フレームワーク: Kivy

BasketballScoreApp().run()仕様書
概要
Basketball Score Appは、バスケットボールの試合中に得点を記録し、リアルタイムでスコアを表示するためのアプリケーションです。このアプリケーションは、延長戦の追加、特定のクォーターの選択、チームおよび選手の選択、得点の追加、スコアの表示およびリセット機能を提供します。
使用技術
- プログラミング言語: Python
- フレームワーク: Kivy
クラスと機能
HighlightableButton クラス
__init__(self, **kwargs): ボタンの初期化。on_touch_down(self, touch): ボタンがタッチされたときに色
を変更。
MainScreen クラス
__init__(self, **kwargs): メイン画面の初期化。得点記録用のリスト、現在のクォーター、選択された選手、延長戦の数などを初期化。get_score_text(self): 現在のスコアを取得し、テキストとして返す。set_period(self, spinner, text): 現在のクォーターを設定。select_player(self, instance): 選択された選手を設定。add_points(self, points): 選択された選手に得点を追加。update_score(self): スコアラベルを更新。update_recent_scores(self): 直近の得点を更新。confirm_reset(self, instance): スコアのリセットを確認するポップアップを表示。reset_scores(self, instance): スコアをリセット。add_ot_period(self, instance): 延長戦を追加。switch_to_score_screen(self, instance): スコア画面に切り替え。
ScoreScreen クラス
__init__(self, **kwargs): スコア画面の初期化。update_score_list(self, scores, ot_count): スコアリストを更新。update_period_selector(self): クォーター選択を更新。filter_scores(self, spinner, text): 選択されたクォーターのスコアをフィルタリング。select_score(self, score_id, instance): 選択されたスコアを設定。edit_selected_score(self, instance): 選択されたスコアを編集。confirm_save(self, instance): スコアの保存を確認するポップアップを表示。save_edited_score(self, instance): 編集されたスコアを保存。switch_to_main_screen(self, instance): メイン画面に切り替え。
以上が、PythonとKivyを使って作成したバスケットボールのスコア記録アプリのコードと仕様書です。冒頭でも書きましたが、試しに作っただけのもので実際には使えませんので、今後改めて実際に利用できるアプリを開発したいと思います。
