[Feature Request] Find seeds with biomes at specific coordinates
Hi, I think it would be really nice to be able to specify where we want the biomes. My use case is finding the seed of an existing world without having access to it (for example a server).
I suggest to load the biome info from a file with the following format, one condition per line:
// X Z BIOME_ID
0 0 1
100 200 7
Which would then search for seeds with plains at (0, 0) and river at (100, 200).
Anyway, nice project, keep working on it!
Currently the my main focus for the repo is to provide a library that allows you to write specific finders like that. But I might make a small example program with a functionality like that at some point. Thanks for the suggestion.
@Badel2 Actually just came up with that idea a few days ago. Let me see if I can make it. I'm a bit more experienced with C++ though.
@Badel2 ok, so I have a working version, but its SUPER slow and written in C++. I'm going to try for GPU acceleration soon.
@gsquaredxc Nice! I was thinking about an efficient way to do the search, because if we need to get the biome at N points there are two options: generate all the area between them (1 call to genArea with a big area), or generate one 1x1 area for each point (N calls to genArea with 1x1 area). The first approach looks better when the points are close to each other, and the "N calls" approach will probably be slower because everything needs to be calculated again from layer 0 (assuming there is no cache, adding a cache to some layers would make this approach much faster).
Regarding GPU acceleration, it would be a nice addition but I don't know if it's simple to implement, as the biome generation code is quite large.
