我正在构建共享白板，但无法共享共享白板。我已经成功创建了一个共享方法，并且我在管理控制台中看到了共享对象，它存在并已连接，但在其他浏览器上看不到绘图。我正在发布整个动作脚本代码。如果可以，请你帮助我。将不胜感激。我对动作脚本真的很陌生。

package

 public class PenSOmc extends Sprite

  // Remote mouse coordinates

  public function PenSOmc ()

    drawing_so.connect(nc);
    drawing_so.addEventListener(SyncEvent.SYNC,doUpdate);

   }
  }

  private function doUpdate (se:SyncEvent):void

      rpenMC.graphics.lineTo(rendX,rendY);
      addChild(rpenMC);
      break;
    }
   }
  }

   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

   }
  }

尝试改变这一点：

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

到

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

谢谢你。尤金

我现在通过添加以下更正使其成为共享白板：

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

但是还有一个问题。共享对象的更新速度不足以使绘制的线条真正成为线条。它们是虚线，因为随着共享对象的间隔更新，一些数据被跳过。我曾经drawing_so.fps = 0 设置帧速率，但在浏览器上仍然不够快。它仅在闪存测试客户端上对服务器足够快。我正在尝试找出更好的方法。
