dictionary - 在 AndEngine 中使用 TMX 文件

Question

我有一个用“Tiled”创建的等距 .TMX 文件，我使用的是 AndEngine GLES1。我想将其用作背景或 map 。如果可能的话，我还希望将我的“玩家”运动与瓷砖联系起来。我知道有一些问题与此有关，但我需要实际代码来显示背景。

这是我唯一的java文件

@Override

编辑切换到 GLES2 后，这给了我一些错误。我正在使用一个新类并插入提供的代码。我需要为其中任何一个创建类吗？是否通过属性链接 TMXproject - android 和该页面底部的“添加”框？谢谢

很遗憾，我只能向您展示我是如何使用 AndEngine GLES2 来实现的。不过，我不确定 GLES1 版本是否可以做到这一点。但也许你可以试着告诉我们你的经历。

首先从 Git 存储库下载 TMX Tilemap 扩展:https://github.com/nicolasgramlich/AndEngineTMXTiledMapExtension

其次将您的项目与 AndEngineTMXTiledMapExtension 项目链接起来(它需要标记为库)

当这两个项目链接在一起时，您实际上可以像这样使用扩展:

 import org.andengine.extension.tmx.TMXLayer;
 import org.andengine.extension.tmx.TMXLoader;
 import org.andengine.extension.tmx.TMXLoader.ITMXTilePropertiesListener;
 import org.andengine.extension.tmx.TMXProperties;
 import org.andengine.extension.tmx.TMXTile;
 import org.andengine.extension.tmx.TMXTileProperty;
 import org.andengine.extension.tmx.TMXTiledMap;
 import org.andengine.extension.tmx.util.constants.TMXIsometricConstants;
 import org.andengine.extension.tmx.util.exception.TMXLoadException;


 public class YourActivity extends SimpleBaseGameActivity {
     private TMXTiledMap tiledMap;
     private TMXLayer tmxLayer;

     @Override
     protected void onCreateResources() {
       try {
           final TMXLoader tmxLoader = new TMXLoader(getAssets(), getTextureManager(), TextureOptions.NEAREST, getVertexBufferObjectManager(), new ITMXTilePropertiesListener() {
            @Override
            public void onTMXTileWithPropertiesCreated(final TMXTiledMap tmxTiledMap, final TMXLayer tmxLayer, final TMXTile tmxTile, final TMXProperties<TMXTileProperty> tmxTileProperties) {
                    // do stuff with tiles that have properties...
            }
           });
           this.tiledMap = tmxLoader.loadFromAsset("tmx/yourMap.tmx");
           this.tiledMap.setIsometricDrawMethod(TMXIsometricConstants.DRAW_METHOD_ISOMETRIC_CULLING_PADDING);
       } catch (final TMXLoadException e) {
            Debug.e(e);
       }

     }

     @Override
     protected Scene onCreateScene() {
           this.tmxLayer = this.tiledMap.getTMXLayers().get(0);  // the 0 is just an index of the layer. It depends on how many layers you created within Tiled
           attachChild(this.tmxLayer);
     }

 }

当您包含等轴测图时，您可能会看到一些像素瑕疵(黑线，图 block 聚集在一起的地方)——这是一个常见问题，在以下位置有一个修复程序: http://code.google.com/p/andenginetmxtiledmapartifactfixer/在这里你可以找到一个 java 程序，你可以用它加载你的 map 文件，它会生成一个你可以在你的项目中使用的固定 map 。在用法下查看您需要哪些参数。

希望这有帮助:)
