This mod requires the following mods to function

gnonme-ModThatIsNotMod-0.3.0 icon

A mod for loading in custom items, making life easier for other mod creators, and a whole lot more.

Preferred version: 0.3.0



A multifunction library for code modders, containing serialization utilities and tweening.

What does it do?

This library holds a bunch of utilities I found necessary to create whilst I created BW Chaos, and that continues to remain useful on other projects. In these utilities are my Prefs system, numerous extension methods, and my serialization utilities (byte array lossless joiner and separator, Vector3 byte converter).

JeviLib also includes many extra utilities I created because I can see others having a use for them.


  • WNP78: Making FieldInjector & telling me about (and helping me with) System.Linq.Expressions, used extensively in Jevil.Patching.
  • Adi: Carrying the code modding category while I waste a bunch of time fucking with Unity for Septic Survival and other things. Also bringing a seafaring misnomer to my attention.
  • Simpleflips: Shoutouts to simpleflips. Its a meme you dip.
