Question

我正在尝试用更新的动画片替换过时的动画片段。

为了做到这一点，我在JSFL中找到旧的动画片段，保存一个参考，然后在其位置添加新版本。

我查看了addItem addItemToDocument并且他们成功添加了剪辑，但我不确定如何将它添加到动画剪辑的旧实例所在的特定图层和框架上。

使用新动画片段的实例替换旧动画片段的所有实例，可能是一种更简单的解决方案。可以通过解析flash文档的时间轴来找到旧动画片段的所有实例。这是一些代码：

var _doc = (fl.getDocumentDOM() ? fl.getDocumentDOM() : fl.createDocument());
var _lib = _doc.library;
fl.outputPanel.clear();
ReplaceItemWithItem('Game Layouts/card holder', 'Game Layouts/card holder new');
function ReplaceItemWithItem(oldmcname, newmcname)
{
  var item1 = GetItem(oldmcname);
  var item2 = GetItem(newmcname);
  if (!item1) return false;
  if (!item2) return false;
  if (oldmcname == newmcname)
    return true;
  return ReplaceAllItems(item1, item2);
}
function ReplaceAllItems(item1, item2)
{
  var timelines = _doc.timelines;
  var i, l = timelines.length;
  var items = _lib.items;
  var changed = false;
// Main timelines
  for (i = 0; i < l; i++)
  {
    var timeline = timelines[i];
    changed |= ReplaceItems(timeline, item1, item2);
  }
// Timelines in library items
  for (i = 0, l = items.length; i < l; i++)
  {
    var item = items[i];
    switch (item.itemType)
    {
    case "movie clip":
    case "graphic":
    case "button":
      changed |= ReplaceItems(item.timeline, item1, item2);
      break;
    }
  }
  return changed;
}
function ReplaceItems(timeline, item1, item2)
{
  var changed = false;
  if (timeline && item1 && item2)
  {
    var layers = timeline.layers;
    var lay, layl = layers.length;
    for (lay = 0; lay < layl; lay++)
    {
      var layer = layers[lay];
      var frames = layer.frames;
      var fr, frl = frames.length;
      for (fr = 0; fr < frl; fr++)
      {
        var frame = frames[fr];
        if (frame && frame.startFrame == fr)
        {
          var elements = frame.elements;
          var e, el = elements.length;
          for (e = 0; e < el; e++)
          {
            var elem = elements[e];
            if (elem && elem.elementType == "instance")  // Elements can be empty
            {
              var item = elem.libraryItem;
              if (item.name == item1.name)
              {
                elem.libraryItem = item2;
                changed = true;
              }
            }
          }
        }
      }
    }
  }
  return changed;
}
function GetItem(itemname)
{
  if (!_lib.selectItem(itemname))
  {
    alert("'" + name + "' does not exist in the library!");
    return null;
  }
  return _lib.getSelectedItems()[0];
}

希望这有帮助！
