    Tsunami is simulated with functions and a tick update, recreating the wave every 20 ticks (1 second), moving forward by 5 blocks.
    
    

• •

💡 Tips & Performance

• • 
    
    Always use /function tsunami_stop before leaving the world to remove leftover water.
    
    

• • 
    
    Don’t spawn multiple tsunamis at once in heavy areas (villages, redstone machines) if your device is low-end.
    
    

• •
