## AI System
### Goal-Based AI
Each robot uses Minecraft's goal selector system with custom goals:
**Miner Robot Goals:**
1. Priority 0: Float (swim)
2. Priority 1: Mining goal (find and mine blocks)
3. Priority 6: Look at player
4. Priority 7: Random look around
**Gardner Robot Goals:**
1. Priority 0: Float
2. Priority 1: Farming goal (harvest, plant, bonemeal)
3. Priority 2: Till farmland goal
4. Priority 6: Look at player
5. Priority 7: Random look around
**Soldier Robot Goals:**
1. Priority 0: Float
2. Priority 1: Follow owner
3. Priority 2: Melee attack
4. Priority 3: Defend owner from threats
5. Priority 6: Look at player
6. Priority 7: Random look around
### Idle Detection & Recovery
- Robots check every second (20 ticks) if they're idle
- If no goals are running, forces goal re-evaluation
- Prevents robots from getting permanently stuck
- Continuously searches for work within their radius

## Known Issues & Debug
### Debug Mode
Current build includes extensive debug logging for troubleshooting:
- Logs every tick check (every second)
- Logs goal execution
- Logs work search results
- Check logs at: `.minecraft/logs/latest.log`
### Common Issues
1. **Robot gets stuck:** Check debug logs to see why goals aren't running
2. **Not mining/farming:** Ensure proper tool in tool slot and correct mode set
3. **Inventory full:** Robot will drop excess items on ground
4. **Won't find work:** Check command radius - robot must be within range
### Performance Notes
- Work cooldowns reduced to 1-2 ticks for responsive behavior
- Goals check continuously when idle
- Vein mining limited to 64 blocks to prevent lag

## Future Enhancements
### Planned Features
- [ ] Crafting recipes for robot spawning
- [ ] Robot upgrade system
- [ ] Energy/fuel system
- [ ] More robot types (lumberjack, builder, fisher/hunter)
- [ ] Team/group management
- [ ] Waypoint system for complex tasks
- [ ] Filter system for mining/farming specific items
- [ ] Remote control interface
- [ ] Robot stat upgrades
### Known Limitations
- Robots may occasionally get stuck (debug mode helps diagnose)
- No energy/durability system yet (robots work indefinitely)
- Limited to single-block operations (no multi-block structures)
- Cannot navigate complex terrain (limited pathfinding)
