Yep it worked! Now I'm just getting pointer errors... Thanks again!

Ahh! That'll do it. I'll fiddle around with that, and see what I can do. Thanks a bunch!

Oh sorry. No, I'm making an engine plugin. http://www.adventuregamestudio.co.uk/site/ags/plugins/engine/
I've been using the template they gave too.

I can't find that file. It's not in my AGS directory, my game's directory, or my code directory.
So I'll just attach my code so far. (But I probably messed up my pointers big time.)

Hi everyone! So, this is the first time I'm posting something on this forum because I have finally given up. 
Anyway, I'm creating my first game in AGS, but first I'm making a plug-in that supports UDP networking. Because I'm crazy. (I have other reasons too, but don't worry: I can code. I just graduated with a degree in computer science! )
I'm writing it in C++ using SFML, and it compiles correctly in Visual Studio 2010. However, when I include it in AGS Editor, the game gives me an error that it cannot parse 'sf', which is the namespace for the SFML functions (see http://www.sfml-dev.org/documentation/2.0/hierarchy.php). I have tried including the namespace sf in my code, but it yells at me. Is there anyone who is more familiar with C++ who can help me? (Or more experience writing plugins that use external dlls?)
Thanks!

Update: I got the plugin to compile while using namespace sf, but I still get the "parse error at 'sf'" from file "__Plugin100.ash"
