Question

我对Flash Actionscript开发非常陌生，并且在用户点击播放时继承了一个开始播放网络流的脚本。

我去了动作并右键点击了动作。下面的代码出现了。我想要实现的是在加载对象后立即播放流（但是obv用户应该能够单击按钮来停止流（每分钟付费）

任何人都可以指出我正确的方向。代码todo可能是触发器或其他地方的东西，这是我能找到的全部。

编辑修复：

你可以试试这个：

var user_id:String = myQueryStrings.user_id;
var site_id:String = myQueryStrings.site_id;
var stream_id:String = myQueryStrings.stream_id;
var RTMP:String = "rtmp://" + myQueryStrings.rtmp + "?" + user_id + "-" + site_id + "-" + stream_id;
var stream_query:String = stream_id + "?" + user_id + "-" + site_id + "-" + stream_id;
