Slick2D +平铺无负载地图 [英] Slick2D + Tiled cant load map

问题描述

我找不到这样的问题。

我有这样的结果：

} catch（SlickException ex）{

} 
 
} 
} 
  

我使用Base64 gzip压缩，所以一切都应该可以。我找不到使我生病的因素;）。可能这个异常是不正确的库放置的结果吗？

解决方案

• 标题可以压缩成gzip和zlib，但zlib不适用于Slick2D。

您的代码很好。这应该是一个愚蠢的错误。

• 在项目中创建一个文件夹并复制它的地图。

然后替换：

  grassMap = new TiledMap（mapa.tmx ）; 
  

由：

 code> grassMap = new TiledMap（folderOfYourMap / mapa.tmx）; 
  

并替换：

  // grassMap.render（0，0）; 
  

by：

 code> grassMap.render（0，0）; 
  

此外，您尚未修复FPS的数量，因此您的CPU工作在100％。 / p>

要修复它，您可以添加：

  app.setVSync（true ）; 
  

编辑：我有同样的问题，但那是因为我的IDE无法看到地图文件夹在项目中。我刚从Eclipse创建一个文件夹（从Package Explorer => New => Folder，你的项目右边的clic，并将你的地图放到这个文件夹中）。

I couldn't find problem like this anywhere.

I have such results:

            Logger.getLogger(SlickTest.class.getName()).log(Level.SEVERE, null, ex);
        }

    }
}

I use Base64 gzip compression so everything should be okay. I can't find the factor which makes me sick ;). Is it possible that this exception is consequence of incorrect libraries placement?

解决方案

• Titled can compress into a gzip and a zlib but the zlib doesn't work with Slick2D.

Your code is good. That should be a silly mistake.

• Create a folder inside your project and copy it your map.

then replace:

grassMap = new TiledMap("mapa.tmx");

by:

grassMap = new TiledMap("folderOfYourMap/mapa.tmx");

and replace:

//grassMap.render(0, 0);

by:

grassMap.render(0, 0);

Also, you haven't fixed your number of FPS, so your CPU work at 100%.

For fix it you can add:

app.setVSync(true);

Edit: I had the same problem but that was because my IDE wasn't able to see the maps folder in the project. I have just create the folder from Eclipse (right clic on your project from the Package Explorer => New => Folder. And past your map into this folder).
