--------------
|
||||
|

This mod adds abandoned mines, similar to MC.
|
||||
|
||||
You can find chest with different stuff like food, resources, ingots or even tools.
|
||||
|
||||
|
||||
Remember that this mod is still beta!
|
||||
|
||||
|
||||
Settings
|
||||
--------
|
||||
|
||||
You can change the spawing of mines by adding/changing these values in minetest.conf
|
||||
|
||||
|
||||
mines_deep_min = -64
|
||||
^ at this deep mines are created
|
||||
mines_deep_max = -380
|
||||
^ up to this deep mines are created
|
||||
mines_spawnfactor = 1.5
|
||||
^ increase this value to generate more mines
