以前にも同様の質問をしたことがありますが、それをきれいにするためにいくつかの助けが必要です。コンテナーにドラッグ アンド ドロップできるスクラブル タイルのような画像を作成していますが、多くのコードを複製しています。また、特定の 1 つのコンテナーではなく、任意の数のコンテナーにタイルをドロップできるようにする方法も知りたいです。コードのスニペットを次に示します。コードの重複を避けたいので、誰か助けてください。複数のコンテナにタイルをドロップする方法を考え出す必要があります。編集では、各コンテナーが文字を読み取り、完全な単語を結合するようにします

これにはテーブルの使用を検討します。テーブルにすべてのタイルが必要なので、myObject [1]myObject[2]を使用しています。

次に、event.targetがタッチされたオブジェクトであるシングルタッチ関数を使用できます（つまり、関数内でevent.targetとして参照されるmyObject [2]に誰かがタッチした場合、コンテナもテーブル内にある場合） ：

container[1]
container[2]

次に、タッチハンドラー内で、次のようなループを実行できます。

for i = 1, #container do
      -- do your code to check to see if your object is in your container
end

event.targetがタイルであるという事実とコンテナーをループすることの組み合わせを使用して、単一のタッチハンドラー関数で回避できるはずです。これにより、すべてのコンテナーに対してテストできます。
