LibGdx 平铺地图渲染问题

Question

我正在尝试学习一本书来学习 LibGDX 游戏引擎，但我在渲染平铺地图时遇到了问题。我想我用 book 写了相同的代码，但它不能得到相同的结果。

这是一个简单的游戏，有一个角色和一张地图。当我渲染我的角色和背景时，没有问题。

它看起来像这样；

但是在我添加我的 tmx 地图屏幕后，只显示了游戏的一部分，没有地图.. 我不知道如何解决这个问题。我真的很困惑。

那些是我的 GameManager 和 ScreenManager 类，也许你能弄清楚我做错了什么......

希望你能帮忙，我在网站上搜索过同样的问题，但我找不到......

static TiledMap map;

让我们在 GameConstants 类中定义地图文件的路径：

public static final String level1 = "data/maps/level1.tmx";

要将地图排队等待加载，请将这些代码行添加到 loadAssets() 方法 在finishedLoading() 方法调用之前的GameManager：

// set the tiled map loader for the assetmanager
assetManager.setLoader(TiledMap.class, new TmxMapLoader(new
InternalFileHandleResolver()));
//load the tiled map
assetManager.load(GameConstants.level1, TiledMap.class);
//blocking method to load all assets
assetManager.finishLoading();

现在，您可以将地图实例加载到 initialize() 方法中： 加载资产（）；

// get the map instance loaded
map = assetManager.get(GameConstants.level1);

要渲染地图，我们需要一个地图渲染器。当我们使用正交地图时， Tiled 包中的 OrthogonalTiledMapRenderer 适用于此 目的。在 GameManager 类中声明它的实例：

public static OrthogonalTiledMapRenderer renderer;
// map renderer
