Tutorials/X-ray glitches

X-ray glitches allow the player to see certain features that are normally hidden behind blocks.

Why bother?
X-ray glitches are useful for locating underground structures such as dungeons and mineshafts. They can also help you find end portal rooms once you are near a stronghold. If you are in the Nether, you can use x-ray glitches to locate fortresses and bastions.

Make sure that you're allowed to use this glitch in servers, though. For most servers, this can count as cheating because you can see the surroundings for mobs, loot chests or precious ores. If others catch you cheating, they can forbid you to do something or even ban you off the server.

General approach
For time efficiency, the game only renders block surfaces if there is a transparent block between the surface and the player. For this purpose, transparent generally means that the player can see through the block, although lava is also transparent for this purpose.

Normally, the camera is inside a transparent block, unless the player is suffocating, in which case the game renders blocks differently. However, it is possible for the camera to be inside a block, but the game does not register that the player is inside. In this case, the player "x-rays" through blocks immediately in the front.

Piston and slab method
This method works by pushing a slab into the player's head. Since slabs are partial blocks, the game does not consider the player to be inside a block. This trick has two main variants: One for looking upward and one for looking downward.

To x-ray upward, you need the following: It is recommended to have multiple slabs, so you can see more. The main setup is as follows, where everything is at head height:
 * 1 lever
 * 2 redstone
 * 1 piston
 * 2 slab

Again, you may wish to surround your head with top slabs wherever possible, to maximize visibility. When you are ready, activate the lever, and the glitch will begin almost immediately.

To x-ray downward, you need the following:
 * 1 lever
 * 2 redstone
 * 2 pistons
 * Several slabs
 * Several full blocks
 * This should include at least 1 sand or other gravity-affected block.

To set this up, start with the same setup as before, but place 2 pistons (1 at head height and one at foot height). The lower piston has a solid block in front, while the upper piston has a bottom slab. Surround yourself with additional blocks, with slabs on top, to maximize visibility. After you pull the lever, the x-ray glitch does not happen yet. Therefore, you can destroy the redstone, including the pistons, and surround yourself further. For the location that was the piston head, placing the full block is tricky, as you cannot look at a suitable surface. Instead, place the sand above where you want it to land, then place the slab as normal. When you are ready to trigger the glitch, enter sneak mode, and your eyes will lie below the top of the slab.

Falling snow method
This method works by gravity-affected blocks landing at the player's feet and piling up to the player's eye level. It can only be used to x-ray downward. You need the following materials:
 * 1 sand (or other cubic, gravity-affected block)
 * 4 top snow
 * Lots of slabs (optional, but increases visibility)

To begin, dig a 1-deep hole, and surround it with bottom slabs. Place a solid block above the hole, high enough that you can walk underneath. Next, place the sand on top, then stack the snow. Finally, stand in the hole, break the block, and enter sneaking.

Piston and composter method (Java Only)
This method works by pushing a piston onto the players head, which allows the player to see nearby caves and underground systems.

To x-ray downward, you need the following:


 * 1 piston
 * 1 composter
 * 1 lever
 * 2 full blocks

To begin, dig a 1-deep hole. Place the composter in the hole, and build a 2-block tall wall on either side of the hole. Then place and switch the lever on the top block of the wall. Finally, step into the composter and place the piston above your head.

Sand/gravel and composter method (Java Only)
This is a cheaper way of the Piston and composter method.

Instead of using pistons, you can use sand, gravel, or concrete powder

You will need the following:


 * 1 sand or gravel or concrete powder block
 * 1 composter

Dig a 3-deep hole. Place the composter inside the hole, then enter it. After entering, put the sand above you, and you're done!

Third Person Camera Method
This method works by using the third-spectator view to see nearby caves around a tunnel.

To begin, enable View Bobbing in settings. Dig a 2 high tunnel anywhere underground, then set your camera to third person by pressing F5. Place the camera ontop of the ceiling of your tunnel and start walking: the view bobbing will glitch the camera through the ceiling of your tunnel allowing you to scout for nearby caves, ravines, mineshafts and dungeons.

This method is by far the cheapest and requires the least effort, but only allows you to see caves that are above your position and may cause some eye-strain, as the caves are only visible for a few frames each second.

Water method (fixed)
This method is simple because all you need is a pool of water with a one block over part of it.

You will need the following:
 * Water
 * 1 solid block

Swim under the block and swim up. Once your head is inside the block you will notice that your air bar is frozen at full and you can x-ray in all directions.

Another X-ray hack, working in bedrock, allows you to ride a pig in a 1 1/2 block high space. Place top slabs one block up from the floor, then ride a pig beneath them. This should glitch you into the ceiling. The only challenge about this hack is getting a pig down to the bedrock layer (which is most effective). It is easy to just push the pig down a shaft into a water landing at the bottom.

Trivia

 * $$ the Stripe Lands may be considered an x-ray bug, in that they follow the same rules for what blocks are visible. This is why the sides of blocks do not always render.
