我使用MapEditor选择了我用我特定的TileMaps创建的地图。我的问题是：
当导出已创建的地图VIA JSON时，通常看起来大多数地图都显示为其地块ID，如下面的代码段所示。
{
"data":[1, 2, 1, 2, 3, 1, 3, 1, 2, 2, 3, 3, 4, 4, 4, 1], <------ TIle Id's
"height":4,
"name":"ground",
"opacity":1,
"properties":
{
"tileLayerProp":"1"
},
"type":"tilelayer",
"visible":true,
"width":4,
"x":0,
"y":0
}
然而，当我在相同的字段中检查我自己导出的JSON地图时，我看到了，
{
"compression":"zlib",
"data":"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",
"encoding":"base64",
"height":100,
"name":"solids",
"opacity":1,
"type":"tilelayer",
"visible":true,
"width":100,
"x":0,
"y":0
},
这两个都是真实的样本，第一个从他们的文档中提取，第二个来自我的原始导出。你可以看到他们的“数据”字段与我的不同之处在于他们是JSONArray，因此我相信这个函数，
public static void load(String path) throws Exception
{
JSONParser parser = new JSONParser();
Object obj = parser.parse(new FileReader(path));
JSONObject jObj = (JSONObject) obj;
JSONArray layers = (JSONArray) jObj.get("layers");
int amount = layers.size();
for (int i = 0; i < amount; i++)
{
JSONObject layer = (JSONObject) layers.get(i);
String type = (String) layer.get("name");
if (type.equals("solids"))
{
WIDTH = (int) ((long)layer.get("width"));
HEIGHT = (int) ((long)layer.get("height"));
solids = parse((JSONArray) layer.get("data"));
}
给了我一些问题。是因为在我的地图的“数据”字段中，我相信这是一个JSONString和一个编码的。
在重新研究之后，似乎我需要解码'数据'，并最终以某种方式转变为您在第一个代码块中看到的'数据'字段。
关于我如何做到这一点的任何提示或者仅仅禁止共同编码？

我彻底浏览了一下，我不知道我应该把tileset.png放在哪里，或者为什么这个世界不会为此加载。您是否创建了自己的.json导出世界来测试它？
答案 0 :(得分：2)
非常接近。不幸的是Inflater比这更复杂：
而不是
Decoder decoder = Base64.getDecoder();
byte[] decodedBytes = decoder.decode((byte[]) layer.get("data"));
Inflater decompresser = new Inflater();
solids = parse((JSONArray)decompresser.inflate(decodedBytes));
试试这个：
Object o = layer.get("data");
if ( o instanceof JSONArray )
solids = parseJSONArray( (JSONArray) o );
else if ( o instanceof String
&& "base64".equals( layer.get( "encoding" ) )
&& "zlib".equals( layer.get( "compression" ) )
)
{
// base64 decode
Decoder decoder = Base64.getDecoder();
byte[] decodedBytes = decoder.decode((String) o);
// zlib decompress
Inflater decompresser = new Inflater();
decompresser.setInput(decodedBytes);
byte[] decompressedBytes = new byte[WIDTH * HEIGHT * 4];
int resultLength = decompresser.inflate(decompressedBytes);
decompresser.end();
// convert `byte[N*4]` to `int[N]`
int[] result = new int[WIDTH * HEIGHT];
ByteBuffer bb = ByteBuffer.wrap(decompressedBytes);
bb.order(ByteOrder.LITTLE_ENDIAN);
bb.asIntBuffer().get(result);
solids = parseIntArray( result );
}
else
throw new RuntimeException( "Unimplemented data type: "
+ o.getClass().getName() );
将原始parse函数重命名为parseJSONArray（例如），
然后将其复制到新功能parseByteArray，如下所示：
private static Image[][] parseIntArray( int[] array )
{
Image[][] layer = new Image[WIDTH][HEIGHT];
for (int x = 0; x < WIDTH; ++x)
for (int y = 0; y < HEIGHT; ++y)
layer[x][y] = getSpriteImage( array[ y * WIDTH + x ] );
return layer;
}
