No, unless you save a world on your computer files
Sorry it's probaly not possible ):
MMMIIINNNEEECCCRRRAAAFFFTTT!!! (minecraft!)
log in to minecraft, click singleplayer, click create new world, then choose what you want in it.
No, Minecraft is a Microsoft exclusive.
Go to the %appdata% folder on your computer, then go to .minecraft, then delete the .bin folder.
Yes. Each world in Minecraft is saved as a separate file. If you open the start menu and search ".minecraft/saves" (without the " signs) you should be brought to a folder containing all your different world saves. They will be named whatever you named them in the first place, eg. JoeBlogs world. Simply copy the world folder you want to the .minecraft/saves folder on the computer you want to play on.
yes, if you use a USB drive i'm not entirely sure how to get the full minecraft on your USB (look on YouTube) but you go into minecraft folder and click "world" and you can make a copy of your minecraft world and put it on your USB drive if you wanna play the world you played on your main computer
A LAN world means if someone is playing Minecraft using the same modem/router as you, they can come into your world and play with you.
a mine craft world never ends on a computer
Because Minecraft is a very absorbing, fun, interesting, and limitless game. If you think he is playing too much Minecraft, send him out side and say: "There's an endless world out there too."
yes, use the magic launcher for minecraft to change the version and then make a world. then revert to the current version.
