現在要改也來不及惹QQ
但視訊網站的模式有很多種
我想 這樣好了
我們來做這個~
點擊房間列表裡的使用者 然後可以選 觀看對方視訊
而LAYOUT也要改一下
如果是觀看對方視訊的同時，聊天介面就會切成上下2半
上面是視訊
視訊再分成2半，左邊是對方，右邊是自已
然後要看對方視訊時，會有邀請的要求給對方
對方同意後 才會打開 視訊的介面出來
這時候第三方要邀請已經在視訊中的人，都會回傳 對方已在視訊聊天中
嗯嗯 就這樣~那就開始ㄅ
通常server code會比較容易看懂，也比較容易了解整個的流程
延展教學(2)的範例，新增了幾個主要的method
client.invite = function(id)//發起邀請
client.sendInviteResponse = function(id,isAccept)//接收方回應是否接受邀請
application.onPublish = function(client, myStream)//發佈視訊
client.exitPrivate = function()//通知要離開private視訊
exitPrivate(user)//離開private視訊
這裡比較重要的地方是，要發佈一個視訊，需要有一個stream name
可以自已定一個字串，但不可以重覆。
假如a發佈一個video_a的串流，那麼 其他使用者只要去聽這個串流名稱video_a就可以看到a所發佈的視訊
client的程式裡有一個特別的用法，你可以在限定參數的event function內，帶入各種想要的參數
Alert.show(userName+"邀請你進入視訊聊天，是否接受?", "hasInvite", Alert.OK|Alert.NO,null,addInviteArguments(onHasInvite,id));
private function addInviteArguments(method:Function, id:String):Function
{
return function(event:Event):void {method.apply(null, [event].concat(id));}
}
private function onHasInvite(e:CloseEvent,id:String):void{
mineNc.call("sendInviteResponse",null,id,Boolean(e.detail==Alert.OK));
}
常常會遇到這種onEvent的參數，不能多帶參數的情況，這時候使用這個方式，可以任意帶多個參數進去；就不用另外做一個變數來記著了。
其它部份就直接看code吧~

下一次，來增加在server上呼叫php api的功能，順便補上一對一密語的功能。~
