Would it be possible to add a way to delete the shell/outer walls of a dungeon while leaving the inside intact?

This is mostly for dungeons that have bedrock for the walls, because it's hard to get rid of them on your own. However, it could also be useful for people who decide that they want their dungeon to have walls made out of a different material, or people who just don't want the outer walls anymore.

/createDungeon alias width length height [type]

Permission: dungeonbuilder.dungeons.create

"Functionally the same as /createEmptyDungeon, however the contents will not be cleared out and torches will not be placed. Intended for situations where you want to create a dungeon out of a pre-existing section of the world.

(v.0.6.6+) There is now an optional type parameter that allows you to change the blocktype of the shell that is generated. Expected values are strings names for the block type, for example "DIRT". You can also use the value "NONE" for situations where you do not want a shell around the dungeon."

Read about plugins before making a ticket :)
