The only way to get a command block in Minecraft is to have cheats on in your world.Once you generated a world like that, type in the following command:/give [your Minecraft character's name] 137 [amount up to 64]That will give you a command block.
make sure you are an op or have permission for the command and type this into the text box (bring up by pressing T) : /tp <yourname> <theirname> if you want to tp to them. if you want to tp them to you you can do /tp <theirname> <yourname>
It should automatically be there.
You put it in your hot bar and chose it and the place it lol
you probably hit f1, that makes your hotbar disappear
