End gateway

The end gateway portal is created after defeating the ender dragon and is used to gain access to the surrounding islands.

Generation
A new end gateway portal generates each time the ender dragon is defeated.

Structure
The end gateway portal is composed of bedrock blocks surrounding a 1 block teleporting block opening. When it is generated, a purple beacon effect shoots out vertically from the top and bottom, which will then slowly dissipate. When a player or entity enters the gateway, or an ender pearl is thrown into it, it emits a yellow beacon beam momentarily.

Due to its size, it is only accessible using ender pearls, or by riding pigs, boats, or minecarts. The end gateway portal is used to warp to other end islands depending on the direction of the ender pearl throw.

Trivia

 * When created without ExitPortal NBT data, although it does not teleport entities, entities entering it will still activate its beam effect.
 * The teleport location for naturally generated gateways are usually around 1,000 blocks from the main island.
 * The texture for the purple and yellow beams that emit is actually a different file than the beacon beam. They are the same texture, though. The file name is end_gateway_beam.png
