刪除緩衝區LibGdx

我爲我的Libgdx遊戲創建了多個Screen s。
每當我退出遊戲（桌面版）時，我在eclipse控制檯中得到一個紅色的句子，顯示Deleting Buffers(1)。
該號碼根據Screen更改，當我退出遊戲時該號碼處於活動狀態。
什麼是「刪除緩衝區」？
我需要擔心嗎？刪除緩衝區LibGdx

此外，我的遊戲的Android版本在第二個Screen崩潰，而桌面版本運行完美。
在此先感謝。屏蔽1

我們需要更多關於「屏幕」的信息。請給我們一些代碼。 – Springrbua

@springbua我按照你的要求添加了代碼，謝謝 –

你在'render'循環中設置了'InputProcessor'。在show（）方法中設置它，因爲它保持不變。只是我見過一點失敗。 – Springrbua

你忘了處理聲音/音樂對象。你可以在你的遊戲類的處理方法中使用它。
