Disclaimer: No, I’m not asking to add ores and such to the game. I know that’s not in the cards.
I was looking into the possibility of adding patches underground dirt to the upper Z levels, so we don’t just have an endless expanse of solid rock as a basis for our underground. Problem is, I’m very new to modding the game, and my knowledge of coding is basically nonexistent. I’ve seen DangerNoodle’s mining mod, and used it before, and so I know it’s possible to use the overmap generation as a workaround for generating stuff underground.
My questions are:
-MINEABLE tag - how difficult would it be to make a variant of this flag for terrain to denote materials soft enough to dig through with a shovel? Would it be better to just make it soft enough to bash down?
-item_action PICKAXE - If the above seems doable, how would I get started on making a new flag for shovel type items to allow you to actually do it?
-Would adding a new underground terrain type break the existing underground features, like basements, etc, that use “fill_ter”: “t_rock”?
-Is there any way to make terrain like this form clusters without it being vanishingly rare in a sea of stone? Soil shouldn’t be particularly rare on Z-1, what with New England’s glacial deposits.
Any help would be greatly appreciated
