RPG Attribute System — Patch Notes

4.1.4

Supported platforms: Minecraft 1.20.1 (Fabric, Forge) · Minecraft 1.21.1 (Fabric, NeoForge) · Minecraft 26.2 (Fabric, NeoForge)

Bug fixes

• 26.2 blank menu / HUD text — text colors updated to opaque ARGB for MC 26.2 GuiGraphics rendering (Attributes menu, Combat Stats tab, level overlay).
• Combat Stats all zeros — vanilla attributes resolved via Attributes.* holders so Health, Damage, Armor, etc. show real values on all loaders.

Upgrade

Replace all RAS jars with 4.1.4 (remove any *(1).jar duplicates). Restart fully.

4.1.3

Supported platforms: Minecraft 1.20.1 (Fabric, Forge) · Minecraft 1.21.1 (Fabric, NeoForge) · Minecraft 26.2 (Fabric, NeoForge)

Bug fixes

• Fabric 26.2 launch crash — removed duplicate PayloadTypeRegistry registration of sync_items_lock that threw Packet type … is already registered! during Fabric main entrypoint.

Upgrade

Replace all RAS jars with 4.1.3 (remove any *(1).jar duplicates). Restart fully. Other MC lines are version-synced only.

4.1.2

Supported platforms: Minecraft 1.20.1 (Fabric, Forge) · Minecraft 1.21.1 (Fabric, NeoForge) · Minecraft 26.2 (Fabric, NeoForge)

Bug fixes

• cmd_to_exc no longer appended on update (#36) — scaffolding only sets missing keys; existing command arrays (even empty) are preserved.
• [param(X)] scaling in tooltips/cache (#37, #39) — baseIncrement resolved from commands so next-value previews match real per-point growth.
• Attributes 9–15 scaffolding + 1.20.1 sync (#38) — missing attribute/display files created safely; 1.20.1 clients receive synced display names and tips.

Upgrade

Update server and clients together. Trim any duplicate cmd_to_exc lines if a prior build appended defaults.

4.1.1

Supported platforms: Minecraft 1.20.1 (Fabric, Forge) · Minecraft 1.21.1 (Fabric, NeoForge) · Minecraft 26.2 (Fabric, NeoForge)

Bug fixes

• Item-lock tooltips for modded / server-only entries — syncs items_lock (enabled, show_tooltip, items_list) from server to client on join so WeaponExpanded and other modded locks show requirement tooltips.
• show_tooltip honored on 1.21.1 / 26.2 — previously ignored on those lines.

Upgrade

No config migration. Update server and clients together; re-join after editing server items_lock.json.

4.1.0

Supported platforms: Minecraft 1.20.1 (Fabric, Forge) · Minecraft 1.21.1 (Fabric, NeoForge) · Minecraft 26.2 (Fabric, NeoForge)

New features

• Public read API — other mods can now query player progression and combat stats without duplicating RAS formulas.
• CombatSnapshot record — immutable snapshot of final MC attribute values after RAS, gear, and effects.
• RasApi.isAvailable() — check that RAS is loaded.
• RasApi.getLevel(Player) — returns the player's current RPG level (server-side).
• RasApi.getCombatSnapshot(Player) — returns final maxHealth, attackDamage, armor, armorToughness, movementSpeed, and rpgLevel.
• Updated API documentation — docs/API.md expanded to cover read and write endpoints.

API reference

Package: tn.nightbeam.ras.api

CombatSnapshot fields:

Integration notes

• All read/write API calls except isAvailable() must run server-side on ServerPlayer.
• Other mods should call getCombatSnapshot() for balancing — do not reimplement RAS scaling math.
• RPG Mob Leveling System 2.0+ consumes this API via reflection for player-based mob scaling and combat rebalance.

Example

import tn.nightbeam.ras.api.RasApi;
import tn.nightbeam.ras.api.CombatSnapshot;

if (RasApi.isAvailable()) {
    int level = RasApi.getLevel(player);
    CombatSnapshot snap = RasApi.getCombatSnapshot(player);
    // snap.maxHealth(), snap.attackDamage(), etc.
}

Breaking changes

None. This is an additive release — all existing respec and template API behavior is unchanged.

4.0.0

• MultiLoader support across 1.20.1, 1.21.1, and 26.2.
• Player XP curve, attribute point allocation, and configurable stat scaling.
• Respec system with Scroll of Rebirth and admin commands.
• Build templates for quick stat distribution.
• Public write API: RasApi.respec(), RasApi.applyTemplate().
• Synced rpg_attribute_system:rpg_level Minecraft attribute.
