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。我想我用书写了相同的代码，但我无法得到相同的结果。

这是一款带有角色和地图的简单游戏。当我渲染我的角色和背景时，没有问题。

它看起来像这样;

但在我添加我的tmx地图屏幕后，只显示游戏的某些部分而没有地图.. 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，也许你可以弄清楚我做错了什么..

public class GameManager {

我希望你能帮忙，我在网站上搜索找到同样的问题，但我不能......

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";

要对映射进行排队以进行加载，请将这些代码行添加到loadAssets（）方法中在finishedLoading（）方法的调用之前的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： loadAssets（）;

// 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。正如我们使用正交映射， Tiled包中的OrthogonalTiledMapRenderer适用于此目的。在GameManager类中声明其实例：

public static OrthogonalTiledMapRenderer renderer;
// map renderer
