How to change difficulty on a Minecraft server
The Difficulty of your server is how challenging the hostile mobs and food system are. There are four different levels.
Hostile will not spawn naturally, player health is restored much faster, and you can not die for hunger or poison damage.
Hostiles can spawn, but their chance of wearing armour is lowered and they will not hit as hard, player health is restored much faster, and hunger and poison can only remove half your health.
Hostiles can spawn, but their chance of wearing armour is lowered. Hunger and poison damage can take you down to half a heart.
Hostile can spawn, and they will spawn a lot more. Zombies will hoard more, and mobs have a high chance of wearing armour. Hunger and poison damage can kill you.
To change the difficulty head to Game Tools then Server Configuration. We're then going to look for the box marked Difficulty. Here you can put peaceful, easy, normal, or hard.
If you're using an older version of Minecraft, this may need to be numbers. So 0, 1, 2, or 3. With 3 being hard.
You will then need to restart the server.
If you don't want to restart the server, you can use a command. To use this command you'll need to be an OP on your server, or have access to the console.
To change the difficulty run /difficulty then what you would like to set it to. So if we wanted it to be hard, we would do: /difficulty hard
If you're running the command from the console don't put the /
That's it you're all done
