帶AS3的共享白板。代碼

我正在構建共享白板，並且無法共享共享白板。我已經成功創建了一個共享方法，並且在管理控制檯中看到共享對象，它已經存在並已連接，但無法在其他瀏覽器上看到圖形。我張貼整個動作代碼。如果可以，請你幫助我。將不勝感激。我對動作非常陌生。帶AS3的共享白板。代碼

現在我已經加入下面的修正使之成爲共享白板：

rpenMC = new MovieClip(); 
    var rpenTipSize:uint = 4; 
    var rpenColor:Number = 0x000000; 
    rpenMC.graphics.lineStyle(rpenTipSize, rpenColor, 1.0);

但仍有一個問題。 sharedobject不會更新得足夠快，因爲繪製的線條確實是線條。它們是虛線，因爲有些數據會因間隔更新而被忽略。我使用drawing_so.fps = 0來設置幀速率，但它在瀏覽器上仍然不夠快。它在閃存測試客戶端到服務器上的速度足夠快。我正在試圖找出更好的方法。

你可以截取點的座標並用線連接它們嗎？ – alxx 2010-08-19 06:26:13

我不知道該怎麼做。 – clientbucket 2010-08-19 14:06:59

你知道該怎麼做嗎？可能嗎？我不確定。這是一個建議或問題嗎？ – clientbucket 2010-08-19 14:43:39

嘗試改變這一點：

drawing_so = SharedObject.getRemote("draw",nc.uri,false);

到

drawing_so = SharedObject.getRemote("draw",nc.uri,true);

謝謝。尤金

這裏有更多的細節 http://livedocs.adobe.com/fms/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file= 00000607.html – Eugene 2010-08-18 23:23:47

這不是解決方案。正確還是錯誤只與它是持久還是不持久有關。這就是當你關閉應用程序時，你是否仍然可以回來並在電路板上查找圖形，具體取決於其他人是否連接到應用程序。 – clientbucket 2010-08-19 00:14:35

我知道，但我聽說它可以幫助，無論如何你有一些異常輸出或跟蹤？你有沒有調試你的代碼？你在SO對象裏面看到了什麼？ – Eugene 2010-08-19 00:33:22
