Minecraft – How to add dungeons to your minecraft world once you’ve already created it

When a chunk is populated, the dungeon generation is always tried 8 times independently at random positions in the chunk. For each generation, given a random size (5x5, 5x7, or 7x7, excluding walls), a dungeon is generated only if the ceiling and floor blocks are solid and there are 1~5 air blocks in the lower half of the surrounding walls.

Possibility? That's complicated to calculate because the probability distribution of air blocks is more complicated and that depends on this. However, you can certainly qualitatively assert that double dungeon is rare. I assert the existence of triple dungeon.

I had this issue too, but don't fear! With just a little bit of effort, you should be able to get rid of your first world. Assuming that you are running on a windows system, go to your start menu and type %appdata% into the search bar. This should bring up a bunch of folders. Go to the one named .minecraft. Inside the .minecraft folder, there should be a folder labeled saves. Go into this folder and you will find the folders for your worlds. Find the folder that has the name of your first world, then delete it by right clicking and pressing delete. Hope this helps! (If you are on Mac, then I really can't help with this problem)
