End portal



An End Portal (sometimes called Ender Portal) is a naturally occurring structure that is used to travel into The End. It can only be found in strongholds, and consists of 12 End Portal block blocks, organized into a horizontal ring shape five blocks square. Each frame block requires an Eye of Ender to activate the portal.

Layout and usage
End Portals are found within the portal room of a stronghold, hanging horizontally over a pool of lava, with a staircase leading up to the portal. A Silverfish spawner sits in the staircase. Some of the portal frame blocks already have Eyes of Ender in them (usually 1-2), while the rest do not.

Upon placing an Eye of Ender in every End Portal Frame block of a specific portal, the portal activates, creating 9 End Portal blocks inside the frame, and allowing the player to access The End. In creative mode the player can copy the end portal frame by pressing the scroll-wheel on their mouse but the portal will only appear if the last eye inserted is facing inwards (the player stands inside the ring to place the final eye). The eyes can not be removed from the portal blocks.

Building a portal
To build a portal to the end, you need the eye of ender. Make it 3 by 3 and use the Eye of Ender and make all the blocks have the eye of ender. It should light up purple.

Behavior
Stepping into an activated End Portal immediately opens up a loading screen, and transports the player to The End - this leaves no time to back out, unlike the Nether Portal while in Survival mode. Upon entering The End, a 5 x 5 horizontal platform of obsidian is spawned at (PC: 0,72,0; Xbox: 100,50,0), often in midair, and the player is placed on top of it. Due to the lack of a return portal being generated, the Ender Portal is one way and the End cannot be escaped from without dying, killing the Ender Dragon, or entering the Nether by placing Nether Portal blocks obtained via inventory editing.

The black portal blocks emit light of level 15, which is as powerful as Glowstone and is the brightest light level there is. It only takes one block of portal to teleport to The End. Through the use of an inventory editor, you can place these portal blocks anywhere, and they will still function as if they were a complete portal. The only exception to this is in The End, where the portal blocks will decay instantly.

Activating the Ender Portal will destroy any blocks located in the center 3 x 3 square, where the resulting Ender Portal blocks will be. They will even destroy Bedrock or another Ender Portal Frame (though neither of these items will occur there naturally). It will destroy fluids, though if the source block is not also removed, then it will immediately flow back through. The destruction of the blocks does not make any sound, and applicable blocks do not drop as resources (exceptions being the top part of a door or the extended part of a vertical piston, which both destroy the whole object and drop them as resources), and events sometimes triggered by block destruction will fail to occur: TNT will simply disappear without detonating, and Monster Eggs will fail to spawn a silverfish. However, Chests, Dispensers, Furnaces, and Jukeboxes will all drop their contents. Mobs will enter the portal (As well as the exit portal) similar to the player.

Exit portal


The portal for exiting The End, which appears (at 0,65,0 on Xbox 360) after the defeat of the Ender Dragon, looks similar to the End Portal but differs in its design. Instead of a frame of Ender Portal Frame blocks, it has a 7-block wide bowl-shaped frame of Bedrock, and a central pillar surrounded by torches and topped with a Dragon Egg.

The exit portal is made up of the same block and tile entity as the End Portal, block 119, but due to being located in the End, teleports players to the Overworld instead of the End. Placing an end portal block in the end using the /give command will result in the block disappearing.

History
The End Portal was part of the Beta 1.9 Pre-release 3 update, but nonfunctional until Pre-release 4. The official release for the Portal was to be Beta 1.9, released as 1.0.0.

In Beta 1.9 Pre-3, the End Portal frame block could be broken by an explosion. As of Beta 1.9 Pre-4, it cannot be destroyed at all, except with mods or creative mode.

The End Portal Frame originally used a partially-transparent blue texture. In Beta 1.9 Pre-4, it was changed to the current End Stone/Eye of Ender texture.

As of Snapshot 12w23a, End Portal frames can be found in the creative menu

In Snapshot 12w36a, all Entities will travel trough portals. This will cause any Silverfish that happen to fall into the Portal to enter The End.

Trivia

 * If an exit portal is generated on a spawner, the fire particles will be left.
 * Unlike the End Portal, the exit portal's frame has a bottom; this means that items dropped into its middle may become unretrievable since they will not fall through and cannot be approached close enough to pick up without the player entering the portal. Care should therefore be taken when attempting to retrieve the Dragon Egg
 * End portals will transport entities from the overworld into the end but not the other way around, even though they do go into the portal.
 * If the Player lacks the required amount of Eyes Of Ender, he/she should search around the Stronghold; Ender Pearls may spawn in chests, though the player will still need blaze powder to craft the Eyes of Ender.
 * If you ride a minecart into an active End portal, then you will not go to the End, but the moment you exit the cart, you will be sent there.
 * If you look closely at the sides, the Portal bricks appear to be made of end stone.
 * End portals are very thin, and only the top face is solid. You can jump through the bottom face, and not the top face.
 * You can see through the bottom of an activated end portal because the portal substance is not visible from the bottom.
 * The portal does not deactivate if you somehow manage to destroy the frame.
 * The non-solid portal blocks can be destroyed in creative mode by punching them.
 * When an ender portal frame block breaks, it makes the same noise as breaking glass.
 * If the player somehow obtains the necessary Ender Portal Frame blocks, it becomes possible for them to build their own portal. However, the portal frame block that last receives the Eye of Ender must be oriented the correct way, placed from inside the circle and facing out. Oddly, the orientation of the other 11 frame blocks does not matter. This only works in the Overworld.
 * Player-made portals may be created adjacent to one another, sharing blocks. However, if they are sharing anything except the corners, the last-placed Eye of Ender may not be in a block 1 block diagonal to or up to 2 blocks adjacent to any Frame block not belonging to that portal.  They may, however, be freely stacked vertically.
 * In Minecraft 1.0.0 there is a glitch where only 3 sides of the incomplete portal will spawn. The player will be unable to go to The End and will have to find a complete portal.
 * Unlike Nether Portals, you are transported the instant you touch the portal.
 * If the Ender Dragon spawns before you activate the portal, you will see a boss health meter when you jump in.
 * Although End Portals do not occur in Classic Flat Superflat worlds, spawning an End Portal via third-party plug-in or mods and entering the portal will still allow the player to reach The End normally.
 * If you drop a gravity following block (gravel, sand or a dragon egg) into the portal it will cause the end portal area to clear, and will be placed on the end side, however it will also be destroyed when other gravity blocks or the player go through the portal.
 * If you're playing in any render distance but far, when the portal blocks reach the "fog" they will turn white, as you can see in the image below.
 * If you hack an Enderdragon outside of The End, the dragon will drop an exit portal that will take you to The End instead of returning you to the Overworld. (Superflat that is an end biome has an ender dragon at 0,0 and you don't need to hack if you want to do it that way.)
