It depends on how you setup the threads and how much you keep static. The threads in most part ARE used for computationally expensive processing. I'll admit that not every turn requires computation, but when it comes to things like battles, they can be. >You might consider looking into the NIO[2] class library, which was >introduced in Java 2 SDK 1.4 and supports multiplexing. I have considered this actually. The problem is that its still extremely new. My main goal at this point was to get a version up and running. At that point I can start adjusting things performance wise. NIO is probably the first thing I will venture into. >-dak > >[1] I think Java's an ugly language. Funny, I think C is ugly.. but it does have many advantages over Java. Java on the other hand is very modular and the way I've designed the game allows for easier additions than you can get with C. Plus, I just like coding, and this was something I thought I'd tackle. I spose I could have gone in the direction of C#, but then we'd have an entirely different conversation.. ;) Thanks for the input, Shay -- +---------------------------------------------------------------+ | 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/ | +---------------------------------------------------------------+
