一般都是可以的，你可以参考下面这个使用XtrAgent的方法
Using XtrAgent with Shockwave movies on the Web
You can license the auto-downloadable Shockwave safe version of XtrAgent to provide it for automatic download from your Web site.
The auto-downloadable Shockwave safe versions are the files
XtrAgent.w32 (Windows) and XtrAgent.ppc (MacOS). Note that the Xtra is only available for Windows, but the package is available for both platforms. The MacOS package is empty and required by Macromedia when authoring movies. It will never be downloaded to an end user's machine.
In order provide the Shockwave versions for automatic download, you'll need to put them in a single location on a server. eg:
www.myserver.com/packs/XtrAgent.ppcwww.myserver.com/packs/XtrAgent.w32Then modify the xtrainfo.txt file in the Director 7 or later folder to reference this location eg:
; DirectXtras
[#namePPC:"XtrAgent.ppc", #nameW32:"XtrAgent.X32",#package:"http://www.myserver.com/packs/XtrAgent"]
Finally, add a reference to the package in your movie.
Open a movie that uses XtrAgent. From the Modify\Movie\Xtras dialog in director,
select the xtra in the list of xtras. The "Download if needed" checkbox should
now be enabled. (If it's not enabled, make sure the filename in xtrainfo.txt matches
the actual filename for the xtra.) Click on the checkbox and director will load
information from the package file for each platform and add it to the current movie.
