I think that there should be a command in the wild that effectively kills you in the wild so that if you want to go to town and its a hoalf hour walk you can instantly. You would drop all your stuff when you use this command so it dosent affect the vinalla part of the game.
Dig 24 blocks of dirt..build a 1x1x24 dirt column.. Jump.. or If it's night just look at endermans and hug creepers.
Oh,I've actually NEVER used a bed before. But what I read of the wiki. If you destroy your bed you go to your first spawn point
There's a 0.01% chance that you'll be teleported to Minecraft Narnia. *starts killing self in wild like crazy*
Destroy your bed and then kill yourself. Then take the long walk back to where you had your bed. What you are asking for may soon be available... I don't have specifics yet but if you read this post, you will have some information. Specifically: "We'll make more announcements in the near future, but look forward to live map feature updates, protection updates & more unique ways to travel far and wide in the wild!"
