Cocos2d-android如何加載TMX tiledmap

我在Eclipse上開發遊戲。我使用Java語言。遊戲需要加載.tmx文件。我不知道我的代碼是否正確。Cocos2d-android如何加載TMX tiledmap

CCSprite bgtitle; 
    CGSize winSize = CCDirector.sharedDirector().displaySize(); 
    protected CCTMXTiledMap tmap; 
    protected CCTMXLayer bbackground; 

protected MenuLayer() { 
     super(); 

     bgtitle = CCSprite.sprite("titlescreen.png"); 
     bgtitle.setPosition(CGPoint.ccp(winSize.width/2.0f, winSize.height/2.0f)); 
     bgtitle.setScaleX(winSize.width/bgtitle.getTexture().getWidth()); 
     bgtitle.setScaleY(winSize.height/bgtitle.getTexture().getHeight()); 
     addChild(bgtitle,0); 

     tmap = CCTMXTiledMap.tiledMap("tutorial1.tmx"); 
      //^ This is where the error occurs 

     bbackground = tmap.layerNamed("Background"); 


     addChild(tmap, 1); 
    }

我從logcat中收到此錯誤信息：

的錯誤是空指針異常，但tilemap的是已經在資產的文件夾。我試圖把它放到其他文件夾，但它仍然沒有工作。任何建議和例子將不勝感激。

從你的日誌中，我想你可能已經爲layer命名了錯誤的名稱。請檢查一次。如果你想引用示例，你可以從庫本身獲取（org.cocos2d.tests包）.check this – Rama

你需要將你的照片複製到工作目錄 - 資產。
