I thought of this idea yesterday when one of the members of my server created a boss arena and asked me to spawn waves of enemies in it. It was fun the first couple of times, but now it's becoming a hassle to have to manage the fight while they play. Here is how it works right now... If the play has the required items to summon the boss, they give them to me Using worldedit, I light the netherrack on fire (creating a border) I spawn enemies on the arena using a pre-agreed on list What would be cool to have... My plugin idea (since I'm not a coder myself) would be to have a chest in the center of the arena. When the specified items are placed in the chest, it triggers the fire and starts spawning a pre-defined list of enemies in the area. (The fire bored wouldn't be completely necessary, it's just a nice touch. ) It would create more uses for certain items on the server, as well as give players a bit more of a challenge.
@turqmelon I already wrote a plugin for this - here's the link http://forums.bukkit.org/threads/fun-bosslevels-create-a-boss-arena-for-dungeons-766.18272/
Yeah, I saw that but it's not really what I wanted. Yours is more spawning mobs in a pre-defined area instead of spawning them if certain conditions are met.
