With version 3.7 I have added a new way that should ease it for people to change certain values and behaviour, especially adaption of radius for opening doors was often requested.

If you want to change these values, either unpack the .pak file from the Starbound mod forums into your Starbound/mods/ folder using the assets_unpacker.exe in Starbound/win_32, or alternatively download the raw unpacked mod files from here: https://www.mediafire .com/file/8dg8zt7tkyygo1m/AutomaticDoors_v3.8_raw.zip/file. Be sure to unsubscribe from the Steam workshop version and delete the automaticDoors.pak in the mods folder.

Then you will find a file called "automaticDoors_default-values.lua" in the now unpacked automaticDoors folder.
Open it in a text-editor, and you can find some basic values which you can now change to your likings.
Keep in mind that you might need to replace doors for the changes to take effect.
