Question

更新由于缺少硬件按钮，平板电脑上的静态通知栏看起来像是一个问题。我只是没想到这一点。无论如何，在TF101的情况下，它返回的分辨率为1280x752，因此大约为1.702（80:47）。如果我使用合适的单位尺寸，如33.5或11.75垂直，我得到适当的缩放，这似乎解决了像素偏斜的问题。 END UPDATE

我一直在使用16x16单位为我的平铺地图设置游戏。我在我的桌面和Android项目上使用分辨率1280x800，我正在测试它以了解它在TF101华硕平板电脑上的外观。我目前使用单位为20x12.5（wxh）的相机并注意到我的桌面项目没有像素缩放，但是当我在我的android上运行游戏时，我得到了奇怪的缩放和绿色水平线。我还可以沿着平板电脑上的x轴进一步移动四分之一单元格，如屏幕截图所示。 android项目中的像素看起来并不均匀。

我将verticalTiles数量设置为12.5f，然后将horizontalTiles数量计算为

verticalTiles = 12.5f;
...
horizontalTiles = (float) width / (float) height * verticalTiles;
camera = new OrthographicCamera(horizontalTiles, verticalTiles);

我的目标是使用不同宽高比的设备，只是看到更多或更少的地图，但似乎无法正常工作。任何帮助将不胜感激。

由于缺少硬件按钮，平板电脑上的静态通知栏看起来像是一个问题。我只是没想到这一点。无论如何，在TF101的情况下，它返回的分辨率为1280x752，因此大约为1.702（80:47）。如果我使用合适的单位尺寸，如33.5或11.75垂直，我得到适当的缩放，这似乎解决了像素偏斜的问题。

另外，虽然这对我的TF101平板电脑有好处，但它并不是一个很好的解决方案。这是一个Gemserk系列，讨论了一个很好的解决方案。
