Airlock Management Software

Yet another airlock script. This one is designed to be scalable. Easy to use for a single minimal airlock, but allows for many separate airlocks to be controlled using one programmable block.

The Minimal Airlock Setup section is intended for folks who just want to get an airlock operational, and may be novice to setting them up. You can skip it to get more top-down directions.

Required Blocks:

• Programmable Block
  
• 2 Doors
  
• Vent
  
• Oxygen Tank

Build a pressurized room with a vent inside. Name one door something that includes the string "[ALI]". This is the usually the door that leads to a pressurized environment. Name the other door something that includes the string "[ALO]". This door should lead to vacuum. Make sure the grid is powered.

Pipe the vent to the oxygen tank.

Put both doors, and the vent in a group. Name the group anything, but include the string "[AL]".

Build a programmable block, and copy-paste the script into it. Click "Run" in the control menu to cycle the airlock.


Airlocks require the following to be in a group to be operational:

• 1 or more doors with the [ALI] tag in their name
  
• 1 or more doors with the [ALO] tag in their name
  
• 1 or more vents

The group must have the [AL] tag in its name
Upon compilation, the script will find the group, and take control of the doors and vent.
The doors tagged with [ALI] are the doors that will open only when the airlock is pressurized. Doors tagged with [ALO] will only open when the airlock is depressurized.

Running the script causes the airlock to cycle from its current state to the other one, i.e. if it is pressuriz(ed/ing) it will start depressurizing, and vice versa. When the airlock is cycling, the script is updating every 10ms. When idle, the script does not run at all.


The script handles unlimited number of airlocks. However, as long as one airlock is cycling, it will be running in continuous mode, updating every 10ms. Please consider this when using scripts in online games.

To add another airlock, simply follow the instructions above. It is wise to name each airlock something different (but still include the [AL] tag!) because the script sorts the groups all alpha-numeric-like. They are then associated with a number. for example: A group with the name "Airlock A [AL]" will be associated with the number 1, if the only other airlock group has the name "Airlock B [AL]", which will then have the number 2.

Run the script with the argument being the number of the airlock you wish to cycle.

If you add lights to an airlock group, it will be green when pressurized, and turn red when depressurizing.

If you add any LCD Panel to an airlock group, it will display status for that airlock. Feel free to adjust the text size and colour, the script doesn't touch those.

The Programmable Block that runs the script will display status for all airlocks that it controls. You can adjust the text size to cut off less important info, to make more important info readable.

Although this is not at all unique to this script, it is handy to build button panels and set up cycling a specific airlock on button press.

A common problem when building airlocks, is that a vent piped up to a full oxygen tank will not depressurize a room. One solution is to have a dedicated tank for all airlocks, but have it piped up to the rest of the grid's conveyor system via connectors. Fill the Airlock tank, unlock the connectors, and depressurize all airlocks. Then the airlock tank will never be too full to depressurize. Perhaps a future update to this script could have an "initialize airlock system" that goes through this process automatically.
