Password protect a multiplayer game?
Solution 1:
As mentioned in the previous answer, you need to disable local server multiplayer. Here are the steps to do that.
If you want no one else to go into your current game:
Press the pause button on the right hand side of your IPhone, iPad or computer.
Press or click "Quit to Title".
Now press or click the options sign.
Then turn off the local server multiplayer.
Or when you are on the title screen:
Press or click play.
Next, press or click the pencil picture next to the game you want no one to go to.
Then again turn off local server multiplayer.
Solution 2:
What you need to do is go to settings and turn off local server multiplayer. Then no one can get into your world and kill you or take your stuff.
