ProMMO 1.9 - Changelog (Plugin)

This document summarizes the most important plugin changes included in ProMMO 1.9.

Highlights (1.9)

• World generator presets were separated into ProMMO, ProMMO:city, ProMMO:citybuild, and ProMMO:wilderness, allowing each preset to use its own terrain profile.
• world_generator.city_build.* now creates flatter terrain for city and building worlds.
• world_generator.wilderness.* now generates more natural hills and rough landscapes for farming and survival worlds.
• Mountain and highland surfaces now use more natural materials such as snow, gravel, calcite, coarse dirt, grass, badlands blocks, and peak variants instead of plain stone.
• Biome placement is now smoother and larger in scale, making world transitions feel more natural.
• Additional biomes were integrated, including Desert, Badlands, Eroded Badlands, Wooded Badlands, Jungle, Bamboo Jungle, Old Growth Taiga, Snowy Slopes, Frozen Peaks, Jagged Peaks, and Stony Peaks.
• Castle generation now blends better into terrain using median and clamped height logic, with smoother courtyards and gate areas.
• Castle generation only processes overlapping castle cells per chunk for better performance.
• Dungeon reset now behaves as a proper run clear: players are removed, non-player entities are cleared, and the world layout remains intact.
• Dungeon reset timers now use real millisecond timestamps instead of Minecraft world time.
• Dungeon difficulty is calculated at match start and cached per dungeon world.
• Dungeon loot now uses weighted rolls without overwriting occupied slots.
• Chest, spawner, and dispenser updates are now deduplicated.
• Dungeon safe zones are configurable through combat.dungeon_safe_zone.enabled and combat.dungeon_safe_zone.radius.
• City industry now uses a unified energy tariff path for power grids, factories, and water systems.
• city_industry.worlds can now restrict factories, water systems, meters, and registration to selected worlds.
• Powered cable states remain visible briefly using city_power.powered_state_ttl_ticks.
• /pm power status now shows detailed network information including cables, consumers, reactors, energy, and demand.
• /pm industry meter now displays registration, power state, and world filter details.
• Industry and power fees can now be deposited directly into the city treasury using city_industry.deposit_fees_to_treasury.
• Pending tariff bills per player can now be limited with city_industry.max_pending_bill_per_player.
• Factories and water systems refund energy exactly to the reactors that supplied it when a process is canceled.
• Administrators can inspect other player factories while production remains owner-only.
• Factories now support multiple configurable recipes under city_industry.factory.recipes.
• Default factory recipes for iron, copper, and gold were added.
• /pm industry meter diagnostics are now fully localized using locale keys.
• city_industry.yml now batches saves for machines, tariffs, and meters instead of writing on every minor change.
• Factory shift-click handling was centralized while still filling only the input slot.
• Blood Moon now rolls once per Minecraft night and overworld using survival.blood_moon.chance_per_night.
• survival.hunger.max_value and survival.thirst.max_value now properly support values above 100.
• The survival boss bar is now reused and updated instead of recreated.
• Normal consumables and custom item right-click effects now share one clamp, sync, and save system.
• Water bottle filling from water mobs now supports cooldown protection with survival.water_bottle_fill_cooldown_ms.
• Medieval and Modern now use separate era worlds generated automatically through era_worlds.*.
• Players are automatically moved into the correct era world on join, respawn, character switch, or era selection.
