Libgdx視口不伸展

Question

我目前在libgdx中創建一個stretchViewPort時出現問題。 正如您在圖像中看到的，我添加的遊戲畫面並未延伸到整個屏幕上，並且有黑色空間。我想知道我做錯了什麼。 我提供了下面的代碼的相關部分。此外，我還嘗試使用onport函數中的onport函數，如下所示：m_stage = new Stage（m_viewport）;但在這種情況下，我得到了一個黑屏，並沒有呈現任何東西（很難有沒有編譯錯誤）。

有人可以指出我做錯了什麼或我失蹤了。 在此先感謝！

親切的問候， Cavasta

Answer 1

你有攝像頭和視口設置爲用於編程世界的價值： 例如。如果你的世界是800 * 480：

camera = new OrthographicCamera(800,480); 
fitViewport = new FitViewport(800, 480, camera); 

Answer 2

必須更新視口時，窗口大小：

@Override 
    public void resize(int width, int height) { 
    m_viewport.update(width, height, true); 
    }
