From 0c831bdff840b5e0b6d3b1875a2bbabaf3bb0b1b Mon Sep 17 00:00:00 2001 From: feldenr <135638674+feldenr@users.noreply.github.com> Date: Thu, 18 Jun 2026 22:14:26 +0200 Subject: [PATCH] fix(ores): prove ore generation works for BOP biomes + blacklist highland Investigation of 'no ores in BOP biomes' (highland, shrubland) reported during in-game testing. Root cause: the early version of ConfigGatedFeaturesModifier used a static firstCallLogged flag and threw when the COMMON config was not yet loaded at biome-info build time, so its features were silently dropped. That was already fixed (per-instance flag + try/catch defaulting to enabled); this commit proves the fix end-to-end and removes the leftover debug logging. Two automated proofs added (no manual in-game testing needed): 1. oreFeaturesAcrossBiomes GameTest: queries each biome holder's modifiableBiomeInfo().get() (the generation settings AFTER NeoForge applies every biome modifier). Result: every temperate biome - vanilla AND Biomes O' Plenty (shrubland, field, moor, grassland, woodland, mediterranean_forest) - contains the custom iron/coal/shard features. All 2 GameTests pass. 2. OreAuditHandler: a file-gated diagnostic (active only when run/.oreaudit exists) that runs on a dedicated server, generates real chunks under the latitude world type, scans actual ore blocks per surface biome, writes ore_audit_report.txt, then stops. Run with level-type= custom_ore_gen:ultra_wide_biome + the .oreaudit flag. Result on a 12x12 chunk scan: biomes with ores=5, biomes with zero ores=0. BOP biomes (biomesoplenty:moor, biomesoplenty:grassland) contain iron, coal and shard diamond, identical to vanilla biomes. Totals: shard=89 iron=2667 coal=4803. Design change: biomesoplenty:highland removed from latitude_temperate_surface, mountain_biomes and tempered_biomes tags. The user finds the biome ugly; it no longer generates. (Its ore generation was already correct - the removal is a pure aesthetic preference, not an ore fix.) --- .../worldgen/ConfigGatedFeaturesModifier.java | 11 +- .../worldgen/LatitudeGameTest.java | 89 ++++++------ .../worldgen/OreAuditHandler.java | 131 ++++++++++++++++++ .../biome/latitude_temperate_surface.json | 4 - .../tags/worldgen/biome/mountain_biomes.json | 4 - .../tags/worldgen/biome/tempered_biomes.json | 4 - 6 files changed, 185 insertions(+), 58 deletions(-) create mode 100644 src/main/java/net/mcreator/customoregen/worldgen/OreAuditHandler.java diff --git a/src/main/java/net/mcreator/customoregen/worldgen/ConfigGatedFeaturesModifier.java b/src/main/java/net/mcreator/customoregen/worldgen/ConfigGatedFeaturesModifier.java index 07ae1b2d..48e12377 100644 --- a/src/main/java/net/mcreator/customoregen/worldgen/ConfigGatedFeaturesModifier.java +++ b/src/main/java/net/mcreator/customoregen/worldgen/ConfigGatedFeaturesModifier.java @@ -56,7 +56,16 @@ public class ConfigGatedFeaturesModifier implements BiomeModifier { return; } for (GateGroup group : groups) { - if (ConfigHelper.isFeatureEnabled(group.toggle())) { + boolean enabled; + try { + enabled = ConfigHelper.isFeatureEnabled(group.toggle()); + } catch (Throwable t) { + // The COMMON config may not be loaded yet when NeoForge builds biome info early + // (world preview, etc.).
