a tiny bit more forest #71735

Instead of slowly and randomly changing stats you can generate a number of overmaps with different forest noise threshold values, count forest tile coverage for each value and compare with real world coverage (~60%). Forest stats for 1337 overmaps of MA mod (which is based on real life data) give 56%: |
Forest coverage for each overmap tile:

There is one problem with that though imo: Your proposed value is the mean forest value across all overmaps combined. A significant amount of the Massachusetts mainland is quite densely forested, excluding the coast (yet to be its own full biome ingame) and the big metropolitan area (implemented as part of #69912, so theres more city mapgen than forest noise there). So if we want a truly realistic value, we may actually need to exclude some MA overmap tiles from factoring into your calculation, most notably the big metropolitan area, coasts and maybe where the forest actually starts to get more dense. |
You can code a gradient for forest noise threshold value - more forest to the west (90%), less forest to the east (0-1%) with an average of 60%, so it would resemble MA forest density. |
Summary
Content "Increase forest amount by a tiny bit"
Purpose of change
Massachusetts and New England in general are quite forested - but the ingame world is not, mostly due to gameplay reasons. However, I had a great™ idea: slowly increase the forest amount over weeks or months with multiple, small PRs adjusting the noise threshold. Until we notice issues or are simply satisfied with the amount of forest.
I proposed this on the devcord and have gotten a thumbs up by Maleclypse and otherwise no (negative) feedback.
Describe the solution
Decrease the forest noise threshold from 0.20 to 0.17. Leave the thick forest noise threshold as it is for now.
Describe alternatives you've considered
Testing
Loads and looks fine. The change is barely noticable, as expected.
Additional context
Could be a good and really simple backport candidate.
