In Survival mode, the player must venture to a stronghold to activate a pre-existing end portal, as end portal frame blocks cannot be obtained naturally. The portal is activated when an eye of ender has been placed in each of the end portal frame blocks, generating 9 end portal blocks within the structure. Eyes of ender cannot be removed from end portal frames.
Note, however, that the end portal blocks do not depend on the end portal frame to exist; thus, one may create standalone portals with commands or by breaking the frames.
The end portal blocks emit a light level of 15--the brightest light level in game. Only one end portal block is needed to teleport to the End. End portal blocks can be placed anywhere with use of the / setblock and / fill commands, and they function as if they were a complete portal.
The end portal frame is available in the Creative inventory or with the pick block option, with the tooltip End Portal.
Dropping a gravity-following block into the portal it causes the end portal area to clear and is placed on the end side; however, it is destroyed when other gravity blocks or the player go through the portal.
