Is there a mod that tells you the percentage makeup of rocks in a world?

[Hiro Protagonist]

I've searched through the mod gallery and couldn't find what I'm looking for, which is a mod that can tell the user, ideally in percentages, what a given generated world's rock percentages are.

This would 

1. avoid exploring forever only to discover the stone type you really wanted/needed is so rare you may never find it

2. hoping you get lucky that what you want/need is right by spawn, if not, recreating over and over

3. not telling you where it is, leaving exploration and discovery as part of the enjoyment.

 

Is there anything like that or, if modders know, is that even possible?

 

Thanks.

I haven't modded VS, but I did mod that other game, and yes, this is something that should be very possible by reading the world data.

Whether it already exists or not, I do not know.

Given that the standard world gen is 1 million by 1 million blocks, and most of that is most certainly base layer igneous, I'm not sure how helpful this would be. Unless it could be narrowed down to within 50k or spawn and only to a certain depth.

100%, if someone were to make this mod, they would want to support configuration options to limit range and possibly depth for it be useful to more people.

If it were me, I'd probably just make it into a server command with range parameters. Trying to search the whole world probably wouldn't be performant and could crash the game, but it should be able to handle a 5,000 or 10,000 block radius around the player.

It would probably need to force-load and/or generate chunks, and if done outside of the game by reading the world save file would probably be limited to only chunks that already generated.

There is a mod called finder but it's out of date. And Geology Map but those actually show you what and where they are. I was hoping for more of a nudge as to if a given world has what someone is looking for in general. But I see the point, the worlds are so large that it might not be useful if it's saying the world is 15% Obsidian but it could be spread out one block at a time over a million blocks, or all in one group.

You could make such a mod, but I doubt it would be very popular. I could be wrong, but I suspect most players already assume there is rock X, it's just a matter of finding it. What would this do for one? Even if you set it to check for rocks within, say 10,000, how does that help if you don't also have it tell you at least what direction it is?

BetterEr Prospecting lets you check all the layers in a certain radius with the prospecting pick.
