Minecraft – stuck on minecraft

Minecraft's difficulty setting is an option; it's not reliant on your saved game.

When you load Minecraft and you're presented with the options to load Singleplayer or Multiplayer, click on Options.... Then, click on the Difficulty option until it cycles back to "Peaceful".

When you load your world, all the hostile monsters will disappear. If you later want to increase the difficulty, do the same thing, but cycle the difficulty to "Easy" or higher.

You can also do this after the world is loaded by pressing Esc to pause the game and clicking on Options... When setting the difficulty to "Peaceful" in-game, hostile mobs will instantly disappear when you return.

This is due to connectivity issues. You are "lagging out" so the server isn't receiving any response from your client and you aren't receiving any information from the server meaning nothing is happening.

Other players will see you just standing there, and you will see "nothing happening" despite everything that everyone else can see. If, like you have said, You are having internet issues try contacting your ISP (internet service provider, the company that provides you internet connection) and they should tell you if everything is ok on their end. If they say everything is ok, you may have to replace your router (I recommend buying a decent one as an investment. Cheap ones tend to work for about 6 months and start declining in performance based on experience.).

As stated by GOD_is_AFK__, you can restart your router and this will tend to temporarily solve the problem. Also ensure that you don't have above 5 devices connected to the internet as it may slow down everything due to traffic.

You can also try other servers to see if the same thing is happening. If it isn't, it is your friends connection. If other people play the server, ask them what their connection is like (are they lagging?). If they are aswell, your friend may have to do what I have just stated above.

Maybe try and run your own server and get them to connect to it and see if she then has the problems.
