私はAndroidゲーム開発に不慣れで、 AndEngine GLES2Javaを使用しています。このコーディングでは、それぞれsmall_boxとbig_boxの2つのスプライトを作成しました.small_boxをbig_boxに、またはその逆にドラッグすると、互いに反発します。これは正常に機能しますが、私の問題は、1番目のsmall_boxと1番目のbigboxが互いに反発することです。 2番目のsmall_boxとbig_boxは反発しません。どうすれば解決できますか？すべてのsmall_boxをすべてのbig_boxからはじき、 small_boxを別のsmall_boxにドラッグするとそれはオーバーラップする必要があり、big_box内でも別のbig_boxに........ Plzこのコードを変更するか、例を使用することで、誰でもこれを支援できます.......
