camera.viewportHeight / 2, 0); 然后你用更新tileMapRenderer tiledMapRenderer.setView(camera); 就 OrthogonalTileMapRenderer 而言，这会将相机的中心（即您看到的屏幕中心）设置为tileMap 坐标系的x=0。因此，tileMap 的位置 x=0（地图的左侧）呈现在屏幕的中心。相机看着 x=0。我的意思是相机查看坐标居中，您没有根据视口的左下点指定相机坐标。

Shape Drawer 在 lib gdx 中不绘制任何内容

很简单，形状抽屉不渲染任何内容，只是一个黑屏。为什么使用起来如此复杂？我无法弄清楚这一点，因为它只是不渲染任何东西，为什么是堆栈
