you can't control whether a user has adobe reader so, no it's not possible.
however, if they have adobe reader and if it's their default pdf viewer you can do that using getURL (as2) or navigateToURL (as3).
I'll be presenting the game to an audience on a known computer, so I can ensure that adobe reader will be used.
So I'm assuming I will then copy the pdf to that computer.. Will this change the code from when I make it on my computer?
I really don't know how to use actionscript well, so in as3 what would the code be?
again, in as3, use navigateToURL. if the pdf and the published html and swf are the same directory use:
