Changelog

v0.6.2

Inventory Space Check for Item Rewards

Inventory space validation - Item rewards (commands using /give) now check that the player has enough inventory space before claiming
UI claim gating - The Rewards page returns an "inventory full" notification (red) when a player tries to claim rewards without space, preserving the unclaimed state
Auto-claim gating - Level-up auto-claim paths (checkAndExecuteRewards, checkGlobalSkillRewards, checkTotalLevelRewards, checkAllRewards) all skip rewards when inventory is full, leaving them unclaimed for later
Non-give commands unaffected - Rewards that don't use /give (e.g., /mmoboost give) are not blocked by inventory checks
Localized notification in all 8 languages (EN, ES, FR, PT, HU, TR, DE, IT)

v0.6.1

Boost Stacking Limits

Hard cap on total XP multiplier - New maxBoostMultiplier setting (default: 5.0x) prevents runaway XP gains regardless of how many boosts are active
Active boost count limits - Configurable caps on simultaneous personal boosts (maxPersonalBoosts, default: 3) and global boosts (maxGlobalBoosts, default: 3)
Stack mode selection - Choose between "additive" (all boosts sum together) or "highest" (best global + best personal only) via boostStackMode setting
Token preservation on limit - When a player tries to activate a boost token at the limit, the token is NOT consumed and an error message is shown
Admin boost gating - /mmoboost global returns an error when the global limit is reached instead of silently creating a boost
Boost Page UI awareness:
- Limits info line shows current state: "Limits: 5.0x cap | additive | Personal 2/3 | Global 1/3"
- Token and permission activate buttons are disabled (red "LIMIT REACHED") when the relevant limit is hit
Admin UI section - New "Boost Stacking Limits" section in /mmoadmin with:
- Text fields for max multiplier, max personal, and max global boosts
- Toggle buttons for additive/highest stack mode
- Save button applies all changes at once
Config version bump - skill-config.json version 8 → 9 (auto-regenerated on first load)
Localized in all 8 languages (EN, ES, FR, PT, HU, TR, DE, IT)

Admin Button on XP Page

Quick admin access - Admins now see an "Admin" tab in the /xp sidebar, just above Settings
Opens the /mmoadmin configuration page directly from the skill overview
Only visible to players with mmoskilltree.admin permission (or OP when permissions disabled)
Server-side permission check on click prevents unauthorized access

Bug Fixes

Fixed global boost permissions not working - AwardBoostPage generated "global" as the scope value in permission strings, but BoostScope only recognizes "all" for global boosts. Permissions like mmoskilltree.xpboosts.all.global.2.30.60 silently failed to parse, causing global boosts created via the Admin Award Boost UI to never appear. Now correctly generates "all" scope (e.g., mmoskilltree.xpboosts.all.all.2.30.60).
- Action required: Any previously awarded global boost permissions contain the wrong scope and must be re-issued. Replace .global. with .all. in existing permission entries, or re-award through the UI.

v0.6.0

Command Rewards v2.0 - Schema Redesign

Major overhaul of the command rewards system with a unified schema and override-based config.

New Schema

Unified rewards list - All rewards are now commands (items given via /give commands)
Override-based config - Config stores only customizations, defaults preserved across updates
Per-command customization:
- localizationKey - Preferred way to set display name (supports all languages)
- displayName - Fallback literal display name
- color - Hex color for UI display (e.g., #ffaa00)
- runAs - CONSOLE (default) or PLAYER
Display logic - Rewards without display info are executed but hidden from UI

New Config Format

{
  "schemaVersion": 1,
  "enabled": true,
  "overrides": {
    "MINING": {
      "10": [
        {
          "command": "/give {player} Ingredient_Bar_Iron --quantity=25",
          "localizationKey": "reward.item.iron_bars",
          "color": "#ffaa00"
        }
      ]
    }
  }
}

Override Semantics

Missing levels use defaults automatically
Set level to empty array [] to disable rewards at that level
New defaults propagate without losing your customizations
Schema version only changes for structural changes

Migration

Automatic V4 migration - Existing configs are converted and backed up
Claimed rewards preserved - Level-based tracking maintained across upgrade

Global Skill Rewards

New reward category: GLOBAL_SKILL - Bonus rewards given to ALL skills at milestone levels
- Tracked per-skill: Mining 50 and Swords 50 each independently trigger level 50 global rewards
- Configurable via GLOBAL_SKILL key in command-rewards.json overrides
- Visible in the player Rewards UI as "Lv X Bonus" rows alongside per-skill rewards
- Default: 1.25x Global XP Boost (15 min) at Level 100 for every skill mastered

XP Boost Token Rewards

Boost tokens as milestone rewards - Level-up milestones now include XP boost tokens
- Personal skill boosts at Lv 50 (1.5x 15min) and Lv 100 (2x 30min) for each skill
- Personal all-skills boosts at Total Lv 100 (1.5x 30min) and Total Lv 350 (2x 45min)
- Global server boosts at Total Lv 500 (1.5x 30min), 750 (2x 30min), 1000 (2x 60min)
- Global boosts broadcast to all online players via /say when activated

Admin Command Rewards UI

New CommandRewardsPage - Visual editor for command rewards, accessible from /mmoadmin
- Category tabs: Gathering, Combat, Crafting, Misc, Total Level, All Skills (Global)
- Skill selector for per-skill categories, hidden for Total Level and All Skills
- Level selector showing all configured milestone levels
- Reward table with columns: Command, Display Name, Loc Key, Color, Status
- Add/Edit section with fields for Command, Display Name, Loc Key, Color
- Inline Disable button on each default reward to create override without that reward
- Remove button on overridden rewards to delete individual entries
- Disable Level to set empty override (no rewards at that level)
- Reset to Default to remove override and restore defaults

Auto-Derived Display Info

Item rewards auto-derive display names from item IDs (e.g., Ingredient_Bar_Iron → "Iron Bars")
Item rewards auto-derive tier colors from item ID patterns:
- Common materials (Iron, Copper): #c8c8c8
- Uncommon (Cobalt, Thorium): #4aff7f
- Rare (Adamantite, Mithril): #4a9eff
- Epic (Onyxium): #c84aff
- Legendary (Prisma, Voidstone): #ffaa4a
- Gems, essences, and tools each have appropriate colors
Rewards without explicit display info now visible in admin UI with auto-derived names

Bug Fixes

Fixed incorrect ore XP rates - Removed explicit low-XP entries for special terrain ores (Ore_Cobalt_Slate, Ore_Adamantite_Magma, Ore_Iron_Basalt) that overrode wildcard patterns with incorrect values (4-6 XP instead of proper ore rates)
Fixed tier label missing in player Rewards UI - localization fallback returned empty string for undefined keys, causing blank tier headers
Fixed Visible boolean type error - Hytale CustomUI requires boolean values for Visible property, not string representations
Fixed display name override in tier headers - Auto-derived item names no longer replace "Level X" tier labels

Technical Changes

- Example: [Tree] +15 HP +5% DMG
- Helps distinguish skill tree rewards from other sources
Improved Time Display - Boost durations and cooldowns now show human-readable formats
- Under 1 hour: mm:ss (e.g., "45:30")
- 1-24 hours: Xh Ym (e.g., "2h 30m")
- Over 24 hours: Xd Yh (e.g., "3d 5h")
- Fully localized time units for all 8 languages

Leaderboard Fix

Total Level Calculation - Fixed leaderboard to use summed skill levels
- Previously used formula-based level from total XP (confusing)
- Now sums individual skill levels for intuitive display
- Example: Mining 50 + Woodcutting 50 = Total Level 100 (not formula result)

Technical

AdminConfigPage.java
- Added #ToggleItemRewards button with event binding
- Calls CommandRewardsConfig.getInstance().setEnabled() on toggle
ViewXpPage.java

v0.5.10

New Command: `/bulksetxp`

Bulk XP command - Set XP for one, many, or all players at once
- Usage: /bulksetxp <skill|all> <value> [targets]
- Targets: Single player name, comma-separated names, or * for all online players
- Examples:
  - /bulksetxp mining 1000 - Set all players to 1000 mining XP
  - /bulksetxp all 0 Player1 - Reset all skills to 0 for Player1
  - /bulksetxp swords 5000 A,B,C - Set swords to 5000 for specific players
- Aliases: setxpall, masssetxp
- Admin permission required

Command Architecture Update

Async command pattern - /mmoboost and /bulksetxp now use AbstractAsyncWorldCommand
- Better console support - commands work reliably from console
- Uses withDefaultArg for optional parameters (cleaner syntax)
- Store operations properly dispatched to world thread via world.execute()
Simplified /mmoboost syntax - Removed --args= prefix
- Old: /mmoboost give --args=Steve|mining|2|30
- New: /mmoboost give Steve|mining|2|30
- Still uses | (pipe) to separate values

Technical

BulkSetXpCommand.java - New command extending AbstractAsyncWorldCommand
- Uses withDefaultArg("targets", ...) with default * for all players
- Store access via entityRef.getStore() inside world.execute() callback
- Validates rewards after XP change (revokes if level dropped)

- Simplified message handling (direct strings instead of localization for admin commands)
CLAUDE.md - Documented async command pattern
- Added "Command Patterns" section explaining AbstractAsyncWorldCommand vs AbstractPlayerCommand
- Critical pattern: world.execute() required for Store operations in async context
- Store thread affinity causes IllegalStateException if accessed from wrong thread
hytale-api.md - Added "Async Commands & World Thread" section
- Documents the thread safety requirement for Store access
- Code examples showing wrong vs right approach
- world.execute(Runnable) dispatches work to world thread

Upgrade Safety

Stat Rewards Reapplied on Config Update - Existing players get correct stat values after mod updates
- When SkillTreeConfig version changes, all stat modifiers (Health, Stamina, Mana) are reapplied
- Online players: stats recalculated immediately on reload/reloaddefaults
- Offline players: stats recalculated on first XP action after login
- Prevents stale stat values from old config versions
Orphaned Reward Cleanup - Removes stat modifiers from rewards that no longer exist
- When skill tree config changes remove tiers or reward IDs, old stat modifiers are cleaned up
- cleanupOrphanedRewards() now calls removeOrphanedStatModifiers() for each removed reward
- Tries removing all stat types (Health, Stamina, Mana) since original reward type is unknown

Balance Changes

Block (STAT_DEFENSE) Nerfed by 50% - Block reduction values were too powerful
- All STAT_DEFENSE skill tree rewards reduced by half
- Before: 4% → 20% range across tiers
- After: 2% → 10% range across tiers
- Maximum stacked Block from all skills now ~45% (was ~90%)
Item Reward Tiers Expanded - Added intermediate tiers for smoother progression with hybrid OSRS formula
- New Level 65 tier for all 16 skills (Expert-level materials)
- New Level 80 tier for all 16 skills (Advanced materials)
- Rewards include mid-to-late game materials like Mithril, Adamantite, Onyxium
- Legendary materials (Prisma, Voidheart, Elemental Essences) at Level 80+

v0.5.4

Improvements

- Format: XP required: Lv10=14.3k | Lv25=95.6k | Lv50=446.2k | Lv80=2.3M | Lv100=10.0M
- Helps server owners understand impact of config changes instantly

Technical

MMOConfigCommand.java - Added showMilestoneXp() helper method with formatted output

v0.5.3

⚠️ BREAKING CHANGE: Leveling formula completely changed. XP requirements are higher at all levels, so existing players will have lower levels with the same XP. Use /mmoconfig formula --args=legacy to restore the old formula.

Hybrid OSRS Leveling Formula

Complete formula overhaul - Combines OSRS exponential curve with quadratic floor
- Early/mid levels ~10% harder than previous quadratic formula
- Endgame scales exponentially (OSRS-style)
- Level 100 = ~10M XP (true endgame grind)
New XP requirements (with default settings):
- Level 10: ~14,270 XP
- Level 25: ~95,573 XP
- Level 50: ~446,222 XP
- Level 80: ~2,274,045 XP
- Level 100: ~10,000,000 XP
Config parameters:
- baseXpPerLevel (default: 300) - Quadratic floor component
- levelScaleMultiplier (default: 200) - OSRS exponential factor
- OSRS component uses 2^(level/7) - each level requires ~10% more XP than the last
- Quadratic floor ensures early/mid levels aren't too easy

Improvements

/mmoconfig formula - Switch between hybrid (OSRS) and legacy (quadratic) leveling formulas
- hybrid: OSRS exponential + quadratic floor (default, ~10M XP at level 100)
- legacy: Simple quadratic (~1.5M XP at level 100 with base=150, scale=2)
/mmoconfig reload - Now reloads ALL config files (was missing XpMaps, Luck, CommandRewards)
/mmoconfig reloaddefaults - Now resets ALL configs to built-in defaults

v0.5.2

Bug Fixes

Harvest Exploit Prevention - Players can no longer gain XP by placing and harvesting items
- Previously, placing a fruit/crop and then harvesting it would award XP via PickupItemEvent

- Separate expiration timer for items: placedItemExpireMinutes (default: 5 minutes)
- Other players CAN still get XP from items you placed (fair multiplayer)
Life Essence Crafting Exploit Prevention - Currency conversion recipes no longer give Crafting XP
- Ingredient_Life_Essence_100_Recipe_ → 0 XP
- Ingredient_Life_Essence_Concentrated_Recipe_ → 0 XP
No +0 XP Notifications - Actions that give 0 XP no longer show notifications

Configuration

placedItemExpireMinutes - New config option in skill-config.json

    ]
  }
}

Per-Config Versioning - Each config file now has its own version number
- Previously: All configs shared a single CURRENT_CONFIG_VERSION = 10
- Now: SkillConfig.CONFIG_VERSION = 3, SkillTreeConfig.CONFIG_VERSION = 2, CommandRewardsConfig.CONFIG_VERSION = 3
- Only the changed config gets backed up when updating, not all configs

UX Improvements

Fractional XP Accumulator - Small XP bonuses (like +5%) now properly accumulate instead of being lost to rounding
- Previously: 10 XP with 5% bonus → 10 * 1.05 = 10.5 → truncated to 10 (bonus lost!)
- Now: Fractional remainder (0.5) is saved and added to next XP gain
- Example: Gain 1: 10.5 → award 10, store 0.5 | Gain 2: 10.5 + 0.5 = 11.0 → award 11
- Players see the bonus manifest every few actions (deterministic, no RNG)
- Mathematically accurate over time - no XP is ever lost

Mana System Design

Players start with 0 mana - it must be earned through skill tree choices. Each skill class has a distinct mana identity:

Staves - THE mana class (360+ max mana potential). Bo staff masters channel mystical energy
Archery - High mana (290+) for wand and spellbook users
Crafting - Moderate mana (305) for enchanting and magical item creation
Block/Harvesting - Low mana (65-180) for survivability or nature attunement
Physical Combat (Swords, Daggers, Axes, Blunt, Polearms) - Minimal mana (15-38). Warriors rely on steel, not sorcery
Gathering (Mining, Woodcutting, Excavation) - Minimal mana (23-38). Laborers focus on physical prowess
Acrobatics/Building - Zero mana. Pure physical disciplines focused on stamina
