I have searched the forums for plug ins that bring additional weapons to the game, but haven't found any. Is this possible? There is balkans weapon mod for standard minecraft that adds new items and weapons to the game. Is it possible to do something like this with bukkit or does something like this already exist and my search skills are weak
Have you read the sticky topic with the big "READ FIRST" letters on them!? -> http://forums.bukkit.org/threads/read-first-what-can-plugins-do.22780/ But this is not possible without the use of an external client modification (like Spout.) People with only a standard Minecraft client can't use new items/blocks.
Yes it is, Balkan's Weapon Mod has been ported to Bukkit and it works great (I've been using it on 1.1-R4 for the past few days, its awesome, highly recommend). However it isn't a plugin, but a mod. To find it search the MC Port Central forums. Clients do need to be modded to connect, but not with Spout - in fact, Spout is likely to crash if connected to a server with ModLoaderMP. Hopefully this situation can be improved in the future..
That's why I said "like Spout" But I'm hoping Mojang will implement more/a client sided API for server mods some day.
Use Spout - for your players it means just another launcher they have to download, for you it means much more possibilities, which usually just work with a client mod, like own GUI's, Items, etc.
