"Coral Utopia" advancement bug report + question regarding suitability value

[uixeL]

Any blocks placed in "high suitability" seem to grant the advancement, not only calcite.

Now for the question: could you share more info in mod features doc regarding suitability? How does it exactly depend on temperature and continentalness? (what's the formula?) What is the minimum suitability needed to get the aforementioned advancement? How does the chance of converting upon a random tick depend on suitability?

Thank you in advance for your answer.

Thanks for reporting the bug.

The math is defined in this file: https://github.com/jsorrell/CarpetSkyAdditions/blob/main/src/main/java/com/jsorrell/carpetskyadditions/helpers/CoralSpreader.java

In pseudocode:

if dimension is not overworld then
    suitability = 0
else if flat world then
    suitability = 0.5
else
    # This value is clamped between 0 and 1
    suitability = 1 - ((temperature - 0.65)^2 + (continentalness + 0.3)^2)

The chance of conversion upon a random tick is suitability * 0.49 + 0.01

Oh, and the advancement triggers at 99%. I'll add this info to the docs.
