Minecraft:End Portal Frame

Template:Infobox block An End portal frame is an indestructible Minecraft:block, 12 of which form an Minecraft:End portal. Minecraft:Eyes of ender must be Template:Control into all 12 empty frames (if not already present upon generation) for the portal to activate and allow passage into the Minecraft:End dimension.

Obtaining

End portal frames, like Minecraft:bedrock, are unobtainable in Survival or Adventure mode. It can be obtained only by accessing the Minecraft:creative inventory or Minecraft:commands.

Natural generation

12 End portal frames generate naturally to form the Minecraft:End portal in each Minecraft:stronghold End portal room, over a pool of Minecraft:lava with a staircase containing a Minecraft:silverfish monster spawner. The frames generate in a 5×5 square formation, with 3 frames on each side, without the corners. Each End portal frame generates facing inward, with a 10% chance of containing an Minecraft:eye of ender.

Each stronghold contains an End portal. Template:IN, each world contains exactly 128 strongholds, so a total of 1,536 End portal frames are generated. Template:IN, there are infinitely many strongholds in each world, so the number of End portal frames that may generate is also infinite. Template:IN, there was only one End portal per world, so 12 End portal frames were generated.

There is an extremely low chance (10^-12 or 10^-10% or one in a trillion) for all twelve End portal frames to be filled in strongholds.

The chart below shows the probability of having each number of eyes of ender filled in (some values may be rounded).

12	10-12	1 : 1,000,000,000,000	10-12	1 : 1,000,000,000,000

Calculating the chance for a specific amount of eyes generating is done with the probability mass function:

P(X=number of eyes) = <math>\binom{12}{k} \cdot 0.1^k \cdot(1-0.1)^{12-k}</math> with k being the number of eyes.

Usage

Template:Control Minecraft:eyes of ender on End portal frames inserts them to the top of the frame if it is not inserted previously.

An End portal frame has a front face that faces the player when placed. Although the facing is almost invisible (one can distinguish only 2 rotations of End portal frames), all End portal frames must be placed correctly and face inward in order to be able to activate the End portal, and if all of the frames have Minecraft:eyes of ender inserted, the portal activates, replacing the inner 3×3 space with Minecraft:End portal blocks.

If an End portal is built in Minecraft:the End, entities are teleported back to the world spawn point in the Overworld, similar to the Minecraft:exit portal.

Redstone

End portal frames output a Minecraft:redstone comparator signal of 15 when an eye is present. If there is no eye in the frame, it outputs a signal of 0.

Light source

End portals frames emit a light level of 1.

Note blocks

End portals frames can be placed under Minecraft:note blocks to produce "bass drum" sound.

Piston interactivity

End portal frames cannot be pushed by Minecraft:pistons. They also cannot be pushed nor pulled by Minecraft:sticky pistons.
