好日子先生們，我已經開始開發一款遊戲，它使用了大量的屏幕（introscreen，閃屏，previewscreen，mainmenuscreen等），並遇到了一些着以下問題：Libgdx：屏幕managaer
從屏幕切換到其他屏幕有時無反應或有問題，有時會一遍又一遍地重複同一屏幕。 我已經回收了一個後退按鈕，我計劃在不同的窗口中使用該按鈕，但只能在其中一個窗口中看到，但在另一個窗口中可見。 我實現我的屏幕屏幕，這是否必須做任何事情與抽象屏幕類，因爲正如我已經看到在不同的示例代碼，他們將他們的屏幕擴展到實現屏幕的某個類。
我對這部分很迷惑，希望能找到適當的解決方案來解決這個問題。
有沒有一種方法可以正確導航或使其更響應我的屏幕？它是否有助於提高遊戲性能我將創建屏幕管理器？屏幕管理員應具有哪些實例？
這是我的mainmenuscreen的代碼，它遇到後退按鈕的問題。

if (yl >= 0 && yl < lines.size())

}當它接收到一個輸入或結束顯示所述文本
，它將設置屏幕以濺射屏幕和飛濺後它將繼續到介紹和MainMenu的，反之亦然。
向我們展示您的代碼，我們將嘗試說明爲什麼其他屏幕有時無響應或錯誤或後退按鈕問題。對於後退按鈕，我現在可以想象的是，您首先繪製後退按鈕，然後繪製背景和其他內容。一世。e後退按鈕與屏幕上的其他紋理重疊。就我而言，所有這些問題都與您的代碼中實現SCREEN無關..其餘嘗試將您的代碼 – Pranav008
@ pranav008請問先生。我試圖顯示我的代碼爲這個屏幕。反正後退按鈕，我也嘗試顯示代碼。 –
