Advanced Configuration

​
Environment Variables

You can use environment variables in configuration files: 
# Use environment variables
database:
  host: "${DB_HOST:localhost}"
  port: "${DB_PORT:3306}"
  
# Default values provided after colon
security:
  max-worlds: "${MAX_WORLDS:10}"

​
Conditional Configuration

# Different settings based on server type
server-type: "${SERVER_TYPE:survival}"

# Conditional blocks
survival-settings:
  enabled: true
  pvp: true
  difficulty: HARD
  
creative-settings:
  enabled: false
  pvp: false
  difficulty: PEACEFUL

​
Configuration Validation

LilWorlds validates configuration on startup:

​
Configuration Commands

​
Runtime Configuration Changes

# Reload all configurations
/worlds reload

# Reload specific files
/worlds reload config
/worlds reload worlds
/worlds reload messages
/worlds reload generators

# Quick reload
/worlds rl

​
World-Specific Configuration

# View current settings
/world config list

​
Best Practices

​
Organization

Tip: Keep your configuration files organized and well-commented for easier maintenance.
# Good: Organized and commented
inventory-groups:
  # Main survival worlds
  survival:
    - world          # Main overworld
    - world_nether   # Nether dimension
    - world_the_end  # End dimension
    
  # Creative building worlds
  creative:
    - creative_world # Main creative world
    - build_world    # Staff building world

​
Security

# Recommended security settings
security:
  enable-rate-limiting: true
  max-worlds-per-player: 5  # Adjust based on your needs
  log-security-events: true
  
  cooldowns:
    world-create: 60   # Longer cooldowns for stability
    world-delete: 300  # Extra protection for deletion

​
Performance

# Recommended performance settings
performance:
  async-world-creation: true
  max-concurrent-world-operations: 2  # Based on server specs
  auto-cleanup-rate-limits: true
  
# Limit loaded worlds
settings:
  auto-load-worlds: false  # Manual loading for better control
