📋 About This Mod
Better Bio-Reactor (Purple Edition)
Enhancements made to the Base Bio-Reactor
See remaining item energy in real-time
Each item will have its energy values displayed and you can watch them tick down in real time from the PDA.
Very useful in helping you determine the quality of fuel sources.
If the Bioreactor is still able to produce energy, you will also see a "+" next to the current charge levels when you hover over the bio-reactor.
Very useful to know at a glance if you need to reload it or not.
Items are processed in parallel
Everything in the bioreactor will decompose at the same time.
The speed at which items decompose is now based on their size. An item that is 2x2 will decompose 4 times faster than an item that is 1x1.
All this ensures that nothing has to "wait its turn" to be processed in the Bioreactor and that there's no penalty or advantage over using items of different sizes.
Variable charging speed
Because all items are processed together and at proportional speeds, the Bioreactor will charge more quickly or slowly
depending on how full it is.
As of version 1. 0. 0, the Better Bio-Reactor is tuned to charge at vanilla speeds when the Bioreactor is half-full.
When less than half-full, charging will be slower.
When completely full, charging will be up to double the vanilla Bioreactor charging speed.
Special Note:
This mod does not alter how much space is available in the base Bioreactor.
