Request: Generate volcanoes at world creation, not chunk creation
Shahelion opened this issue · 11 comments
I'll be exploring, and find something interesting like a village, then suddenly BAM volcano everywhere, no more village. Also, if the volcano overwrites a special structure (Thaumcraft Obelisks, ChromatiCraft Pylons) it doesn't update them like it should (they still think they're intact).
For reference; to generate the volcanoes in such a manner would involve quite a fair amount of complex map code that barely works well with minecraft in the first place, in basic terms it involves creating a custom biome heightmap system specifically for the volcano surface, with or without adding an additional biome type.
Short answer; nearly impossible to pull off well.
Which blocks are being overwritten? The volcanoes generally leave ground blocks intact but will clear above ground blocks as you would not expect there to be any.
It's not really possible to allow villages to remain without also allowing trees as they both use logs...
Why not make volcanoes a biome? If I had time I'd come back specifically to take a look at this and do it well, because I've always wanted to learn about worldgen, but alas
Making a dedicated biome for them is not a bad idea, however neither is it a simple one due to minecraft's nature. Additionally there's compatibility with other biome mods to look at.
A half-way option however may be to make a barren-like biome and allow volcanoes to only generate there and in oceans, however it may take a bit to get the gen chances correct between the two. Or make an island biome too.
The generator is very careful about which blocks it replaces. I'll consider moving volcanoes to their own biome, if I can come up with a good way to implement this.

The last time a volcano overwrote something, it was a Chromaticraft Pylon. Some of the base and one of the pillars was gone, which breaks the pylon itself.
Worldgen is a deceptively tricky business. Its hard to account for EVERYTHING that other mods may generate. I will definitely look into this though.
Maybe have a whitelist of things it can override instead of a blacklist? Just include vanilla blocks that are usually found on the surface. Dirt, anything oredict'd as logs or stone, etc.
IMO, biome route would be best. Considering the nature of 'em. Also may be a good idea to review the feature list ;)
