コードが壊れているのはなぜですか？
はじめに: 「Choose Your Own Adventure」ゲームを作ろうとしています。
レイアウトは次のように構成されます: bPage = ユーザーがどのページにいるかを示すボタン。クリックしてページを手動で変更 (まだ実装されていません) bOne: 最初のパスを通過 bTwo: 2 番目のパスを通過
完全に機能するスプラッシュ画面もありますが、「開始」をクリックすると、このレイアウトが読み込まれ、ハングします (無限ループの可能性があります)。
誰かが理由を教えてもらえますか? できるだけ多くのコメントを入れようとしたので、自明であるはずです
好きなだけ質問してください:)
