でのスプライトの画像の高さは、ちょっと私はこのコード行にある例外のルート突き止めてきたばかり：奇妙な例外がスローさ：SFML
>= obj2->GetPosition().y + (obj2->GetCenter().y - obj2->GetImage()->GetHeight()))
をしかし、私はそれを引き起こしていただきました！に見当もつかない..... 2つのスプライトポインタを取る関数内に奇妙な部分があり、GetImage（） - > GetHeight（）はオブジェクト1では機能しますが、オブジェクト2では2回目ではありません...
助けてください！私はなぜこれが起こっているのだろうか考えていない！おかげ
すべてのコード：（私は、以前の投稿のコードの行を検索）
