與AS3共享的白板。 碼

Question

我正在構建共享白板，但無法共享共享白板。 我已經成功創建了一個共享方法，並且在管理控制台中看到了該共享對象，該共享對象已經存在並且已連接，但是在其他瀏覽器上看不到該圖形。 我要發布整個動作腳本代碼。 如果可以，請你幫助我。 將不勝感激。 我真的是ActionScript的新手。

Answer 1

這有效：

  private var rpenMC:MovieClip;
    // Mouse Coordinates
    private var startX:int;
    private var startY:int;
    private var endX:int;
    private var endY:int;

  // Remote mouse coordinates
    private var rstartX:int;
    private var rstartY:int;
    private var rendX:int;
    private var rendY:int;


  public function PenSOmc ()

  }

  private function doUpdate (se:SyncEvent):void

    switch(se.changeList[cl].code)

      //penMC.graphics.moveTo(rstartX,rstartY);
      penMC.graphics.lineTo(rendX,rendY);
      break;
    }
   }
  }

  private function startDrawing (e:MouseEvent):void
  {
   trace("Start drawing");
   isDrawing = true;
   var penTipSize:uint = 1;
   var penColor:Number = 0x000000;
   penMC.graphics.lineStyle(penTipSize, penColor, 1.0);
   startX = mouseX;
   startY = mouseY;
   penMC.graphics.moveTo(startX, startY);
  }

  private function stopDrawing (e:MouseEvent):void
  {
   trace("Stop drawing");
   isDrawing = false;
  }

    drawing_so.setProperty("points",startX + "," + startY + "," + endX + "," + endY);
    penMC.graphics.lineTo(endX, endY);
   }
  }

 }

}

Answer 2

嘗試更改此：

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

至

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

謝謝。 尤金

Answer 3

我現在通過添加以下更正使其成為共享白板：

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

但是仍然存在一個問題。 共享對象的更新速度不足以使繪制的線真正成為線。 而是用虛線表示，因為隨着間隔的更新共享對象時會跳過一些數據。 我使用drawing_so.fps = 0來設置幀速率，但是從瀏覽器上來看它仍然不夠快。 它僅在服務器上的Flash測試客戶端上足夠快。 我正在努力尋找一種更好的方法。
