HI, XTRA Here....

In this thread I'll be presenting a picture tutorial of my Terraria Bi - directional Auto Airlock.

IMG_20210307_170540.jpg IMG_20210307_170718.jpg

This Airlock is completely automated with the use of "player sensor's," and is surprisingly compact considering how reliable and unbreakable it is.

With multiple fail - safe mechanisms built into the circuit like "compensation for water displacement, underflow, and overflow," as well as "double activation lockout precautions, and in-built world load detection." This Airlock is not only "Multiplayer Proof," but is also guaranteed to always do what it's made to do "and it has interactional hazard light's!"

Here's a link to the full informational video showcase and explanation if you're interested:
_______________________________________

With that out of the way, let's get into the tutorial, where I'll not only show you how to build this thing, but will also give you some information about it, and other hints and tips along the way...


First thing, Here's the Airlock we'll be building:

Here's the finished product with all the wire's:

As stated, "It's suprisingly compact!"


Here we can see the bare bones of what we'll need for this build.
(excluding water, lava, wire, and actuators!):

"I won't bother providing a list. If you don't know what some of these blocks are,
you probably shouldn't be building this anyway!"


Quick note/tip's, for anyone who's wondering:
IMG_20210307_215252.jpg
Pumps will stay on block's after they're actuated!

"On this note, I highly suggest you actuate yours if you're building this!"
IMG_20210307_215202.jpg
Also, you can breathe while under water when standing in actuated blocks.
This is why I have a full strip of them in the Airlock!...


Anyway... Starting off, we want to make sure that when placing the logic gate lamps,
we're placing them in the correct ON/OFF state!

"DOUBLE CHECK!"


Next, take note of the three (x3) 3 second timer's,
and the four (x4) 1/4 second timer's being used and be sure to use the same:

Here we can see the two (x2) water sensor's,
and the five (x5) player sensor's we'll be using in the build:

(((IMPORTANT - You will have to either place the water and player sensors last, or replace them at the end of the build and/or when ever you build around them, as sensors bug out and become permanently inactive until replaced whenever phisical blocks and objects are built around them (excluding wiring and wiring components), so be sure to place the sensors after building!)))


Next, we can't forget about the six (x6) junction boxes pictured here:
IMG_20210307_180246.jpg


With that checklist out of the way, we can now proceed with the blue wire:

Take note of the five (x5) actuators on the right side of the Airlock...


Moving on to the red wire now:
IMG_20210307_185132.jpg

Here we have five (x5) more actuators on the left side of the Airlock...


Now the green wire:

Last but not least, the yellow wire:
IMG_20210307_200825.jpg

Remember to take you're time and "DOUBLE CHECK!"


After finishing the wire, we can fill the empty space in with block's:
IMG_20210307_190807.jpg

At the very least, we will need to make a pocket or two for the lava...


Whether you fill the area in or just make a pocket, we can now place the lava in the pocket of either one or both sides as displayed in the next two images:
IMG_20210307_190929.jpg

As well as the lava, we can also place some water in the bottom chamber as pictured:
IMG_20210307_191017.jpg
For those who don't know, lava won't turn into obsidian when water touches it if you have a transparent block placed inside the lava. Instead, the water will evaporate!...


On that note, we can finish up here by simply placing one last bucket of lava in the pocket at the top left of the build where the lonesome junction box is:
IMG_20210307_191604.jpg IMG_20210307_191638.jpg
Note, this single block of lava would be placed at you're chosen water line level in the external body of water wherever you choose to build this. The purpose of it is to prevent the water overflowing!


With that, we have completed the Airlock, and this is what it should look like upon first using it:

"CONGRATULATIONS!..."

You may be wondering what the extra pump at the top is for?

If you really want to know, you should visit the link attached at the top leading to the complete informational showcase and explanation.

But, in short, you won't have to worry about it if you are going to use this Airlock in a full sized Terraria ocean.

If you are planning on using this in a smaller body of water, you may want to check out the showcase, as it explains how the water may "very slowly" deplete over time after using the Airlock ""only several hundred times.""

Seriously though, this is a Terraria bug and will happen with any and every Airlock! But you shouldn't have to worry about it with my Airlock design.

Though, if you have any concerns or would like to know more information, again, go watch the showcase. Or you can contact me directly, I would be happy to answer any questions...

With that being said, this tutorial is now over.

Thank you for stopping by and having a read...

Also, I hope you enjoy you're new Terraria Airlock if you chose to build one...


Regards, XTRA...
