I recently saw the plugin http://forums.bukkit.org/threads/me...minecraft-mobs-zombie-content-1-0-1-r1.52728/ I really wanted this on my server, but i thought how IMPOSSIBLE it would be to start up. Is it possible that every minecraft week, the world goes into "Full Moon" Mode. "The Full Moon Rises" The Full Moon mode would be night for the length of 2 minecraft days. It would be a truly terrifying time.
There is a plugin called angry wolves, where every 7 days wolves spawn aggressive, we could definitely snatch the code from that part and make it so mobs spawn at a 3x rate or something.
I remember trying that plugin out! I believe either it was outdated or my server was, but it looks very promising. Do you have a way to increase the spawn rate?
Weirdly not, seems like an obvious idea though :s I will add that option All of the features are listed here http://dev.bukkit.org/server-mods/bloodmoon/pages/config/
