Pushers allow you to make a 'door' out of almost any solid block in Minecraft. You can also create a much larger entrance than with a normal 'door' item, such as the 2 x 3 structure described in this guide. Once all the redstone wiring is done, your door will open faster than your "Sesame, open!" can say. Pushers are available in Minecraft Pocket Edition as of update 0.15.0.

Steps

Part 1 of 3: Building the skeleton

Make an Automatic Piston Door in Minecraft Step 1

Step 1. Gather your materials

See the Supplies section at the end of the article for a full list of building materials. If you're not sure how to build it, use the following recipes:

  • Sticky Piston = Pushing Machine + Slime Ball
  • Redstone torch = redstone + stick
  • Pressure plate = stone + stone (melts cobble into stone)
  • Lever = cobblestone + stick

Step 2. Make a 2 x 3 structure of stone

Place six blocks of stone in the following pattern: two blocks wide and three blocks high. This will be the 'door' that will be pushed aside by the machines to let you in.

You can use almost any solid block besides stone. There are a few blocks that don't work with sticky pistons, such as pumpkins or (in Creative mode) bedrock

Step 3. Point sticky pistons at this structure from both sides

Place a pillar of three sticky pistons with their green pusher heads to the left of the stone structure. Leave a space of a block between the stone and the pushers. Repeat with another pillar of three sticky pistons on the right side.

These pushers are located on both sides of the door, not the front and rear. All blocks should be placed in a row

Step 4. Place a redstone torch behind each sticky piston pillar

Place a redstone torch on the ground directly behind the stone side of the lowest pusher. Repeat for the pillar on the other side.

The lowest two pushers of each pillar should be extended to touch the stone structure

Step 5. Place stone over the redstone torch

To fire the top pusher, place a stone block directly above the redstone torch (behind the middle pusher). Place redstone dust on top of this stone. Repeat for the other pillar.

  • Again, you can use any solid material except stone.
  • Redstone "dust" is slang for plain redstone (placed on a block).

Make an Automatic Piston Door in Minecraft Step 6

Step 1. Dig a trench four blocks deep in front of the door

Make sure the trench extends two blocks from the door, and all the way from one redstone torch to the other. You should eventually have a trench 4 deep x 2 wide x 8 long.

Step 2. Place more redstone torches under the first pair

Stand at the bottom of the trench and look at the wall below your wall structure. Dig two blocks under your first redstone torch and place a second redstone torch on the floor in this cavity -- the pushers should now retreat, taking the rock with them. Repeat for the other side. A profile view of the far left and far right pillar should now look like this, from top to bottom:

  • redstone dust
  • Stone
  • Redstone Torch (on the ground)
  • Block Earth (Ground Level)
  • Redstone Torch (one block below)
  • block earth
  • Bottom of the trench

Step 3. Place a layer of stone in the trench directly in front of the door

Place four blocks of rock in the center of the trench, lifting it up one layer. Leave the rest of the trench at the current depth.

Step 4. Place redstone torches on both sides of this layer

Place one redstone torch on the left and one on the right. These flares should be on the side of the block, not on the ground.

Step 5. Cover the trench with redstone

Draw a line of redstone dust between the two torches on the left (the pushers should stick out again when this happens). Repeat for the two torches on the right. Finish it off by covering all four blocks in the raised area with redstone dust.

Step 6. Create a platform in front of the door

Place a 2 x 2 stone on the ground in front of the door, directly above the elevation in your trench.

Be careful not to destroy redstone dust when you place it

Make an Automatic Piston Door in Minecraft Step 12

Step 7. Place pressure plates on this platform

Place two stone pressure plates at the end of this platform. When you step on it, they should activate the redstone below, causing the pushers to retract. The door will now open, and won't close again until you step off the pressure plates.

  • However, be careful when walking. If you take too long, the door will close by itself and suffocate your game character.
  • If the door doesn't open, double-check that your redstone dust and torches are in the right place.

Part 3 of 3: Being able to lock the door from both sides

Make an Automatic Piston Door in Minecraft Step 13

Step 1. Dig a tunnel under the door

Stand on the platform at the bottom of your trench. Dig a tunnel under the door, two blocks past it. The tunnel should be two blocks wide, directly under the stones of the (closed) door. The floor of the tunnel should be level with the elevated platform.

Make an Automatic Piston Door in Minecraft Step 14

Step 2. Cover the tunnel floor completely with redstone dust

Make sure it connects to the other redstone.

Make an Automatic Piston Door in Minecraft Step 15

Step 3. Place pressure plates on the ground above the tunnel

Return to the surface. Place pressure plates in two squares in front of the door, directly above the buried redstone. These pressure plates are supposed to open the door when you step on them, just like the pair on the other side.

Make an Automatic Piston Door in Minecraft Step 16

Step 4. Attach a handle to the redstone on the other side

You can now use your door. However, any roaming enemy can walk over the pressure plates and go through the door. Adding a lever allows you to create a lock:

  • Place the handle in a suitable place on the floor. If you want to be able to lock the door from both sides, make a hole in the wall and place the handle there.
  • Place more redstone dust to connect the track to the left of the trench with the lever.
  • Place another line of redstone to connect the track to the right of the trench with the lever.
Make an Automatic Piston Door in Minecraft Step 17

Step 5. Troubleshoot potential handle issues

Right click on the lever and walk over the pressure plates. Right click on the handle again and repeat. The doors should only open when the handle is in either position. If this doesn't work, examine the trail of redstone to the lever:

  • Redstone tracks can only rise one block distance at a time. Place blocks in the shape of a 'staircase' to raise it from the bottom of the trench to ground level.
  • If the redstone closest to the lever is dark (unloaded), remove a block of redstone dust earlier in the track. Replace this with a redstone repeater to boost the signal. Make sure you position the repeater so that the front of it is pointing in the direction the signal is supposed to move.

Step 6. Cover the mechanism

Now your door should be fully functional. Cover all wiring with blocks of your choice. Make sure all the redstone dust has a block of air directly above it or it will stop working.
