Question

我是Google Maps API v2的新手，想要整合通过此基本链接提供的地图：https://tiles.guildwars2.com/{continent_id}/{floor}/{zoom}/{x}/{y}.jpg。我的问题是，一切都好，但让我们开始使用以下内容：

1）如何设置任何一侧没有灰色空间的地图大小？ 2）如何正确移动地图，因为我显然有4个参数，而我可以使用getTileUrl一次只更改3个参数？ 3）为什么瓷砖混合而且没有以正确的顺序显示？

地图文档可在此处获得： http://wiki.guildwars2.com/wiki/API:2/maps http://wiki.guildwars2.com/wiki/API:Maps

Answer 1

好的，因为学校因为学校的休息，我发现了除了第一件事以外的一切。

我对错误的瓷砖的错误是我没有正确的参数顺序。

另外还有很多参数，我会在不久的将来为自己设计一个解决方法。

所以我会在粉碎显示器之前关闭线程并打开一个新线程，因为某些东西不起作用。

在Google地图中使用自定义图块
