**Supported platforms:** Minecraft 1.20.1 (Fabric, Forge) · Minecraft 1.21.1 (Fabric, NeoForge) ### New features - **Unified leveling architecture** — mob levels are calculated once on spawn through `LevelCalculationService`, with attribute scaling, classification, and storage handled by dedicated services. - **RPG Attribute System integration** — optional player-based scaling (`nearest`, `highest_nearby`, `average_nearby`) and combat rebalance when `rpg_attribute_system` 4.1+ is installed. - **Public API (`RmlApi`)** — other mods can read mob levels, force recalculation, and inspect level breakdowns. - **Debug commands** — `/rml inspect`, `/rml recalculate`, `/rml config`, `/rml distance` (op level 2). - **Percentage attribute scaling** — per-rule `additive` or `percent` modes in `attributes_settings.json`. - **Gson JSON config** — all settings live under `config/rpgmoblevelingsystem/` (replaces Jauml on 1.20.1). - **Namespace bans** — exclude entire mods (e.g. `cobblemon`) via `banned_namespaces`. - **Hostile-only scaling** — optional global or per-rule hostile filter. - **Structure & boss level locks** — `structureMinLevels` and `bossLevelLocks` in config. - **Custom loot by level** — optional `loot_by_level.json` for level-band drops. - **Configurable name format** — `%mob_name% [Lv. %level%]` in `global_settings.json`. - **Ascendant elites** — ported to common code on all loaders (buffs, boss bar, death loot). - **Documentation** — usage guide, API reference, and community feedback resolution report in `docs/`. ### Bug fixes - **Distance scaling** — now uses Euclidean block distance divided by `scaleDistance` (was incorrectly using squared distance). - **Day scaling** — uses total elapsed world time (`gameTime / 24000`) instead of wrap-sensitive day time alone. - **Movement speed corruption** — attributes applied via idempotent named modifiers instead of mutating base values; speed skipped for non-hostiles by default. - **Locked mob HP** — locked/boss mobs no longer keep incorrect stacked HP forever. - **Zero XP in modded dimensions** — XP scaling works on Fabric (mixin) and NeoForge/Forge (event). - **Ender Dragon / boss scaling** — dedicated boss lock defaults and locked-level path. - **Overlay console spam** — removed periodic debug logging; optional `overlayDebug` flag. - **Jade / name display** — overlay no longer overwrites mob custom names with `Lv.N`. - **Performance** — levels applied once on spawn, never every tick; early exit for banned namespaces. - **Low-level mobs vs high RAS players** — optional `playerBalanceEnabled` scales mob power relative to nearby player combat snapshot. ### Config changes New / updated files in `config/rpgmoblevelingsystem/`: | File | What's new | |------|------------| | `scale_settings.json` | `rounding_mode`, `playerScaleMode`, `playerScaleRadius`, `playerScaleFactor`, balance ratios | | `attributes_settings.json` | `mode` (`additive` / `percent`), `hostileOnly` per rule | | `mobs_list_settings.json` | `banned_namespaces`, `hostileOnly`, `bossLevelLocks`, `structureMinLevels` | | `global_settings.json` | `nameFormat`, `jadeEnabled`, `overlayDebug` | | `loot_by_level.json` | Level-band custom drops (disabled by default) | Legacy configs with `scaleDistance >= 100000` and near-zero progression auto-migrate on first launch. ### Breaking changes - **Config format** — JSON only in 2.0; Jauml string configs on 1.20.1 are no longer read. - **Attribute application** — uses Minecraft attribute modifiers instead of permanent `setBaseValue` mutations. Existing worlds keep stored level tags; use `/rml recalculate` to refresh mobs if needed. ### For mod developers ```java import tn.nightbeam.rpgmoblevelingsystem.api.RmlApi; int level = RmlApi.getLevel(entity); RmlApi.recalculate(entity); LevelDebugBreakdown breakdown = RmlApi.getDebugBreakdown(entity); ``` See `docs/API.md` for full reference.
