Already had that working before I sent the email. :) What I am particularly interested is the actual CircleMUD implementation. In this case, I am going to use this for our spell system, so I need some sort of design idea on how to treat the data needed for the Perl-scriped spell code. For instance, how would I pass data between the Perl script and Circle? Those kind of implementations are what I cannot understand yet. I mean, I understand how to pass a Perl sub a set of vars, but I don't really grasp how to get the things I need from the character/victim/room/object affected by the spell, and how would I go about sending stuff back to the mud? For instance, if I wanted to make an affect spell, I suppose that I could pass the Perl sub an array with vars, then return an array with the affects in it and use the AV array functions to get the data from the array. I could perhaps return an array with all the data, that has a set structure, that I then parse in the C code. Uhm. Or not? I know that embedded scripting languages are the tabu of the coding world, and you are not allowed to talk about this by some unwritten law, but help me out here a little... *cries* Regards, /Torgny -- +---------------------------------------------------------------+ | FAQ: http://qsilver.queensu.ca/~fletchra/Circle/list-faq.html | | Archives: http://post.queensu.ca/listserv/wwwarch/circle.html | | Newbie List: http://groups.yahoo.com/group/circle-newbies/ | +---------------------------------------------------------------+
