AmunRa-GC-0.3.4
== Version 0.3.4 ==
- added readme, added some other stuff which might be necessary
- made motherships actually respect maxMothershipTier
- added config options for Mothership speed and fuel factors
- added a new alien villager (does not spawn naturally yet)
- added hydroponics unit
So, it works like this: you build the Hydroponics Unit, power it from below, then you can attach oxygen pipes to any side. Through the GUI you can plant seeds in there (only wheat for now). The unit doesn't need power to grow wheat, but it needs light. You can also throw in some bonemeal through the GUI to accelerate the process.
If powered, it will produce oxygen, similar to an oxygen collector, depending on how grown the plant is. The oxygen output should be about what an oxygen collector would produce from 4 wheat fields, so you would need a lot of these. Alternatively, there is a config value to increase the efficiency.
Once the wheat is fully grown, you can also harvest it via the GUI.
