Tutorials/Passlock door

From Minecraft Wiki
Jump to: navigation, search

These are simple tutorials on how to make a passlock door. A passlock door means that a player must turn on the right combination of levers in order for the door to open. This can be very useful on Multiplayer maps if in Adventure mode. Note that if you are playing in multiplayer in Survival mode, players will be able to open the door with a button, or just mine the door.

Basic Design[edit]

Follow these steps carefully.

Step 1

First, place an 11 block row of any block, and made it two blocks high. Then, add a row of 7 branching off both sides.

Step 2

Add levers/switches on the bottom row of the 11 blocks, followed by signs on the top row. Each sign should have a number in order (1, 2, 3 etc.). Alternatively, you can make the signs have letters or words on them instead.

Step 3

Place a repeater in front of each block of the row that has the levers.

Step 4

According to the password you want, you need to place a block in front of the switches that make up your password and put a redstone torch on top of each. For example, if your password for 1-2-6 (like in the example), each block and redstone torch is placed in front of switches 1, 2 and 6.

Step 5

Next, place a block in front of each block that you just placed. Fill all the spaces in between the blocks with repeaters.

Step 6

Place a row of redstone dust in front of the repeaters and blocks.

Step 7

Place a strand of the redstone, starting from the middle, down to the 2nd last row. At the last row, place one block in front of the redstone.

Step 8

Add one redstone torch on top of the block just added. Then, add another block on top of the torch. Once you've done this, add a door on top of that block.

Step 9

Your passlock door is finished. To activate, flick all of the levers of which you had the password made up of, but no others. For example, if your password is 1-2-6, turn the levers below the signs that say 1, 2, and 6, on, but all the others should be off. The door should open.

Final Touches

Cover all the redstone with blocks, so that players can't see it.

Notes[edit]

You can have up to 29 inputs. Larger amounts are more secure; the number of possibilities is 2^c, where c is the number of levers used. You can't have more than 29 inputs with this design, as the redstone signal won't travel far enough.
