From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Thu, 13 Jan 2022 23:05:53 -0800 Subject: [PATCH] Add missing structure set seed configs The 4 missing structure set seed configs are strongholds, mineshafts, buried treasure, and ancient cities. Strongholds use a ring placement scheme which isn't random so they utilize the world seed by default, this adds a config to override it for just generating the ring positions. Mineshafts and Buried Treasure structure sets are special cases where the "salt" that can be defined for them via datapacks has 0 effect because the difference between the spacing and separation is 1 which is used as the upper bound in the random with salt. So the random always returns the same int (0) so the salt has no effect. This adds seeds/salts to the frequency reducer which has a similar effect.
