Out the game in three dimensional mode
2013 2014
Survival mode is a mode in minecraft where you have to collect your own blocks, get your own food, and survive! Be careful at night because that's when monsters come out! If a monster attacks you, you will lose your lives and have to start over by losing the blocks you had in your possession. Basically, you have to "survive" on your own without unlimited supplies.
Yes. If you switch to peaceful, monster spawners will stay there, but they won't spawn any monsters.
You're on creative mode and activated fly mode by tapping the space bar twice. You can use shift to descend, fly mode can be cancelled by tapping space twice again, or by landing.
It's actually 1.3 but it will come out pretty soon.
Currently, you cannot change day to night but it is thought to come in a few updates.
