與AndEngine一起使用TMX文件

我有一個用「Tiled」創建的等軸測.TMX文件，我使用的是AndEngine GLES1。我想用它作爲背景或地圖。如果可能的話，我也希望將我的「玩家」運動綁在瓦片上。我知道有一些問題需要處理，但我需要實際的代碼來顯示背景。與AndEngine一起使用TMX文件

這是我唯一的java文件

     return true; 
    } 
return false; 
} 


@Override

} 
    }

編輯切換到GLES2這是給我一些錯誤之後。我正在使用一個新類並插入提供的代碼。我是否需要爲其中的任何一個創建類？通過屬性 - android和頁面底部的「add」框鏈接TMXproject？謝謝

不幸的是，我只能告訴你我是怎麼用AndEngine GLES2做的。但我不確定，GLES1版本可能會這樣。但也許你可以嘗試告訴我們你的經歷。

第一下載從Git倉庫的TMX tilemap的擴展：https://github.com/nicolasgramlich/AndEngineTMXTiledMapExtension

第二鏈路與AndEngineTMXTiledMapExtension工程項目（需要將其標記爲庫）

當這些兩個項目鏈接，你可以實際使用這樣的擴展：

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); 
    } 

}

當您包含等軸測圖時，您可能會看到一些像素僞像（黑色線條，拼貼塊在一起） - 這是一個常見問題，並且存在以下修復： http://code.google.com/p/andenginetmxtiledmapartifactfixer/ 此處您會發現一個Java程序，可以加載你的地圖文件，這將產生一個固定的地圖，你可以在你的項目中使用。查看的使用情況查看您需要哪些參數。

希望這有助於反正:)

Christoph，謝謝你的回答。我只是想要移植到GLES2，無論如何我需要，我正在嘗試將TMXextension與GLES1鏈接起來。 – AspiretoCode

GLES2確實可以正常工作。我希望你沒有太多的麻煩移植。如果您有任何問題需要解決TMX問題，請告訴我 - 我會很樂意分享我所做的體驗，即使它不是Mouch;） – GameDroids

Christoph，我已經更改爲GLES2，將所有擴展加載爲圖書館項目並鏈接到我的項目。但是我在這些命令中遇到了一些錯誤。就像它說「新的TMXLoader」已被棄用。然後它給了我關於context.getAssets（），vertexBufferObjectManager的錯誤。還有一些等距的東西。如果你能幫助我，那會很棒。 – AspiretoCode

請確保您有主TMXExtension，先通過拉回購下來（我想克隆）。然後使用我的repo url添加遙控器。

然後你想拉下等軸測分支並檢查出來。
