allow-nether=true # Whether to enable the Nether world (if disabled, the Nether world will not be generated)

max-world-size=29999984 # Set the maximum radius value for the world boundary, in blocks. Successful execution of commands can set the world boundary larger, # but it will not exceed the maximum block limit set here. If the max-world-size set exceeds the default size, it will have no effect.
level-type=DEFAULT # Determine the type of map generated #DEFAULT – standard world #FLAT – flat world #LARGEBIOMES – preset world, but all biomes are larger (only available after snapshot 12w19a or official version 1.3) #AMPLIFIED – preset world, but world generation height is increased (only available after snapshot 13w36a or official version 1.7.2) #CUSTOMIZED – since snapshot 14w21b, servers also support custom terrain. The method is to paste the code in generator-settings

If the packet is n bytes or larger, it will be compressed. # Therefore, a lower value will cause more packets to be compressed, but if the compressed packet bytes are too small, it will be counterproductive. #-1 – permanently disable packet compression #0 – compress all packets #(recommended between 64-1500)
