We'll I'm playing on this realm with my friends and it's on peaceful and I can't change it because my friends own the realm and they don't know how to change the difficulty either. I think it's on realm settings but I don't know because I don't have a realm. Please try to help.
Minecraft Difficulty Realm Change?
I'm not entirely sure how realms works but I'm pretty sure that your friend can use commands. If so, then tell them to use this command:
/difficulty (difficulty)
So basically, if your friend wants it on easy rather than peaceful then you would have them use this command:
/difficulty easy
If your friend is able to use commands then that should work.
Click "Start LAN World" when you have toggled the cheats on. Back in the game, press the "t" key to bring up the ingame console box. Enter the command "/gamemode c" to change your game mode to creative. (If you want to switch back to survival mode, use the command "/gamemode s".) If you need some privacy, use LEO Privacy Guard 3.0. There're many security features included in it and for you there's one most useful featrue and that is Private SMS. Install it and have the total security in your device.
