如何用Scoreoid为你的flash游戏创建一个排行榜

她。 3D打印店铺

你应该知道Scoreoid一个好的特点是没有任何SDK，Scoreoid公开的Web API是基于标准的RESTful HTTP/HTTps协议。

好吧，这是新的游戏版本，前五名显示在舞台的右下角：游戏链接
你知道该怎么玩：鼠标左键启动发动机，躲避方块，尽可能走的更远并收集圆形。注意右下角的排行榜。

我创建了另一个sprite类Leaderboard，包含一个动态文本，并且对Main类做了一些修改。在脚本中，和以前版本不同的地方我加了高亮。（29行，46行，173-198行）

}
}

正如你所见，它只需使用getScores()方法，按特定顺序(requestVars.order)在期望的数据(requestVars.order_by)中检索一个号码(requestVars.limit)的游戏分数。

你会得到一个像这样的XML：

<scores>
<player username="Demo Name" email="" first_name="" last_name="" platform="">
<score score="42185" difficulty="0" platform="" leaderboard="" created="2013-06-07 18:32:42" data=""/>
</player>
<player username="Demo Name" email="" first_name="" last_name="" platform="">
<score score="42085" difficulty="0" platform="" leaderboard="" created="2013-06-05 21:14:17" data=""/>
</player>
<player username="Demo Name" email="" first_name="" last_name="" platform="">
<score score="41940" difficulty="0" platform="" leaderboard="" created="2013-06-11 00:00:33" data=""/>
</player>
<player username="Demo Name" email="" first_name="" last_name="" platform="">
<score score="39175" difficulty="0" platform="" leaderboard="" created="2013-06-06 13:10:19" data=""/>
</player>
<player username="Demo Name" email="" first_name="" last_name="" platform="">
<score score="38540" difficulty="0" platform="" leaderboard="" created="2013-06-11 00:44:44" data=""/>
</player>
</scores>

这很容易被loaderCompleteHandler函数解析。如果你不知道如何解析XML,请参阅了解AS3和XML
