こんにちは、私のような人のようなものです。 私はAndroid用の2Dゲームに取り組んでいます。私はいくつか問題があります。 ほぼ完成しましたが、私のゲームでコレクターズコインが欲しいです。私はすでにコインのメインコードで終了しています、彼らは私の障害を乗り越えていて、あなたはそれらを集めることができます。しかし、私はそれらを無作為に産卵させることはできません：私はここに私のコードです助けてくれることを願って： 私コインクラス：私はあなたが私を助けることができると思いますは私の第2dアンドロイドゲームに問題があります

を実装して拡張します

private Animation animation = new Animation();

for (int i = 0; i < image.length; i++)
{

}
animation.setFrames(image);

}

}
