Better Booms
There are several client mods that add new types of TNT to the game, but as far as I know, no server mods - until now.
Better Booms is a simple plugin that lets you place simple formations of blocks around TNT that will give the TNT new behaviors.
WARNING These can be VERY destructive and protection/permission plugins may not prevent annihilation of stuff. However, if the explosion event is cancelled by a plugin with a lower event handler (this is set to HIGHEST because it has ignoreCancelled turned on) then your stuff will be safe.
For a list of TNT types, see the TNT types page.
It's probably not a good idea to deploy this on a public server... it's very destructive and a little buggy. But have fun blowing up stuff with friends :D
work great on bukkit r2.0 and very funy !!!
great, :)
