I'm looking to set up "incentives" for exploring different areas on my minecraft SMP server.
One idea I had was for items to spawn in chests scattered in out of the way areas that spawn harder to find items every certain interval if the chest is empty. So for example, a chest might spawn a diamond pick once every 48 hours if it doesn't already have a pick. (so a person doesn't happen upon a chest full of diamond picks)
Are there any bukkit plugins that support this, or some combination of plugins that would allow me to do this?
