In the game Minecraft to get to the Edge is possible in 2 ways:
1) build a portal to the Ender world;
2) find the portal to the Ender World.
How to build a portal to the Ender world
To build a portal to the Ender world in Minecraft you will need: 12 Ender blocks world and the Ender for each block. The blocks locate in the fortresses. Keep in mind that they are gray-green in color.
Original build 3 blocks on all sides to get a square. The eye of Ender must be placed so that his black eyes looked into the portal. Place Eye of Ender on all the blocks of the portal as needed.
Remember that it is impossible to be on the transition portal, or you can go directly to the Ender world. That space of the portal will turn black to indicate that the passage is open. Now check the functioning of the portal: go out into the ordinary world, and then go back to the portal. In the portal you must destroy the dragon. To do this, destroy towers, and then the Ender dragon.
How to find the portal to the Ender world
In order to find the portal to the Ender world you need to use the Eye of Ender, found with weapons in a pearl edge. Take in your right hand the eyes of Ender and use the right mouse button. Eye of Ender is to fly toward the gate of the portal, emitting a purple glow.
You can learn more about what is the portal there when the Eye begin to fall to the ground.
Found the portal, place the Eye of Ender in each block. The portal to the Ender world will open.
