In the mini world, there are many brightly styled doors. However, a common mistake many novice builders make when installing doors is to place a switch only on the outside of the door, which results in the door opening only from the front, not from inside the house. Therefore, in order to solve this problem, a big boss made a high-level two-way door, not only simple and easy to learn, but also sliding, want to learn the small partners quickly look over.

Step 1: If you want to make a two-way door, you need to make a sliding device for the door. Dig a hole with a length of 3 and a depth of 3 in an open location. Next, a sliding block is placed in the underground layer on the far right side of the pit, and a minus marker and two rocks are placed in turn on the left side of the sliding block. Then, continue to build a face of length 3 and height 2 with rock blocks above the minus marker and the two rocks. Finally, smash the top right corner of the face and replace it with a plus marker.

Step 2: Place two vertically connected rocks on the ground one unit apart from each other on the left and right side of the sliding block as stone pillars to open the door. Next, on the right side of the left rock, a rock, a transmitter facing underground, and an electric energy comparator are placed in sequence. Note: When installing the launcher, you need to dig the pit first, then put the launcher, and finally the pit can be repaired after the installation. Then, in the direction of the launcher along the door (behind), a rock is placed and connected to the rear rock column with a blue power line. Finally, a blue power line connects the most forward rock column to the rock on the left side of the launcher.

Step 3: Through the two steps just now, the door can be opened one-way, and the last step is to increase the two-way opening function. A bucket of water is added to the launcher, followed by two power lines and power amplifiers behind the comparator. Next, connect the power amplifier to the sliding block with a red power wire. Finally, a button is installed on each of the two rock pillars, and the two-way sliding door is completed.
