I made this while trying to learn how to develop plugins.

It is very simple, it will just turn any cobble stone mined into one of the ores listed below. Its weighted in the order listed below with Coal having the highest chance and Netherite block having the lowest chance. However there is a very high chance that the block will turn back into cobble stone when mined and nothing drops to make it balanced so you can just farm ores infinitely using an automated cobble generator.


Coal
Iron
Gold
Redstone
Lapis
Diamond
Netherrite Ore

If you want the Source Code just let me know.
