LibGdx瓷磚地圖呈現的問題

Question

我試着去學習一本書來學習LibGDX遊戲引擎，但我有渲染瓷磚地圖的問題。我認爲我用書寫了相同的代碼，但我不能得到相同的結果。

它是一個簡單的遊戲，帶有角色和地圖。當我渲染我的角色和背景時，沒有任何問題。

它看起來像這樣;

但之後，我加入我的TMX地圖屏幕顯示的遊戲，沒有地圖.. 我不知道如何解決這個..我真的困惑的只是一些部分。

這些都是我的遊戲管理器和ScreenManager類，也許你能找出我做錯了什麼..

Answer 1

static TiledMap map; 

讓我們定義在GameConstants類的映射文件的路徑：

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

要排隊地圖加載，之前添加幾行代碼到loadAssets（）方法遊戲管理的 finishedLoading（）方法的調用：

// 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(); 

現在，你可以得到的地圖實例加載到initialize（）方法： loadAssets（）;

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

要渲染地圖，我們需要一個地圖渲染器。由於我們使用的是正交映射，所以來自Tiled包的OrthogonalTiledMapRenderer適用於這個 的目的。聲明它的實例在遊戲管理類：

public static OrthogonalTiledMapRenderer renderer; 
// map renderer
