How It Works

Automatic Tracking

┌─────────────────────────────────────────────────────────────┐
│  PLAYER JOIN                                                │
├─────────────────────────────────────────────────────────────┤
│  1. Fetch all skill levels via MMOSkillTreeAPI              │
│  2. Compare each skill level with milestones                │
│  3. Grant all reached achievements (catch-up)               │
│  4. Cache current levels                                    │
└─────────────────────────────────────────────────────────────┘
                              ↓
┌─────────────────────────────────────────────────────────────┐
│  PERIODIC CHECK (every 30 seconds)                          │
├─────────────────────────────────────────────────────────────┤
│  For each online player:                                    │
│  1. Fetch current levels                                    │
│  2. Compare with cached levels                              │
│  3. On level-up → Check & grant achievements                │
│  4. Update cache                                            │
└─────────────────────────────────────────────────────────────┘

Conditional Loading

Server Start:
1. Achievement Plugin loads standard achievements
2. MMO Skill Tree integration is checked
3. If available: mmo_skills_achievements.json is loaded
4. SkillLevelTracker is activated

Without MMO Skill Tree:
- No MMO achievements in gallery
- No SkillLevelTracker active
- No performance cost

Troubleshooting

Achievements Not Appearing

1. Verify MMO Skill Tree is installed:

   Check plugins folder for MMOSkillTree.jar

2. Check server logs:

   Look for "MMO Skill Tree integration enabled"

3. Restart the server: Integration is checked on startup

XP Rewards Not Working

1. Check skill name spelling: Use exact skill names (e.g., "Mining", not "mining")

2. Verify MMO Skill Tree API: Check server logs for API errors

3. Test with admin command:

   /achievementadmin grant <player> total_level_100

Skill Level Not Updating

1. Wait for polling cycle: Levels are checked every 30 seconds

2. Force check on rejoin: Player disconnect/reconnect triggers catch-up

3. Check cached levels: Cache may be out of sync after server issues

Technical Details

API Integration

The plugin uses reflection to access MMO Skill Tree API:

// Level queries
MMOSkillTreeAPI.getLevel(store, ref, skillType)
MMOSkillTreeAPI.getTotalLevel(store, ref)
MMOSkillTreeAPI.getAllLevels(store, ref)

// XP manipulation
MMOSkillTreeAPI.addXp(store, ref, skillType, amount)

// Skill enumeration
MMOSkillTreeAPI.getSkillTypes()

Soft Dependency Pattern

The integration follows the same pattern as LuckPerms:

• Lazy initialization on first access
• Graceful fallback if not available
• No hard dependency in plugin.yml

Performance

• Polling interval: 30 seconds
• Per-player cost: Minimal (single API call)
• Cache strategy: Level changes only trigger checks
• No performance impact when MMO Skill Tree is not installed
