与AndEngine一起使用TMX文件

我有一个用“Tiled”创建的等轴测.TMX文件，我使用的是AndEngine GLES1。我想用它作为背景或地图。如果可能的话，我也希望将我的“玩家”运动绑在瓦片上。我知道有一些问题需要处理，但我需要实际的代码来显示背景。与AndEngine一起使用TMX文件

这是我唯一的java文件

编辑切换到GLES2这是给我一些错误之后。我正在使用一个新类并插入提供的代码。我是否需要为其中的任何一个创建类？通过属性 - android和页面底部的“add”框链接TMXproject？谢谢

不幸的是，我只能告诉你我是怎么用AndEngine GLES2做的。但我不确定，GLES1版本可能会这样。但也许你可以尝试告诉我们你的经历。

第一下载从Git仓库的TMX tilemap的扩展：https://github.com/nicolasgramlich/AndEngineTMXTiledMapExtension

第二链路与AndEngineTMXTiledMapExtension工程项目（需要将其标记为库）

当这些两个项目链接，你可以实际使用这样的扩展：

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伪像（黑色线条，拼贴块在一起） - 这是一个常见问题，并且存在以下修复： http://code.google.com/p/andenginetmxtiledmapartifactfixer/ 此处您会发现一个Java程序，可以加载你的地图文件，这将产生一个固定的地图，你可以在你的项目中使用。查看的使用情况查看您需要哪些参数。

希望这有助于反正:)

Christoph，谢谢你的回答。我只是想要移植到GLES2，无论如何我需要，我正在尝试将TMXextension与GLES1链接起来。 – AspiretoCode

GLES2确实可以正常工作。我希望你没有太多的麻烦移植。如果您有任何问题需要解决TMX问题，请告诉我 - 我会很乐意分享我所做的体验，即使它不是Mouch;） – GameDroids

Christoph，我已经更改为GLES2，将所有扩展加载为图书馆项目并链接到我的项目。但是我在这些命令中遇到了一些错误。就像它说“新的TMXLoader”已被弃用。然后它给了我关于context.getAssets（），vertexBufferObjectManager的错误。还有一些等距的东西。如果你能帮助我，那会很棒。 – AspiretoCode

请确保您有主TMXExtension，先通过拉回购下来（我想克隆）。然后使用我的repo url添加遥控器。

然后你想拉下等轴测分支并检查出来。

学习git的好地方是here。
