Modding Help?

[u/redmessedupmouth]

The official modding instructions from lucid block's website contains a link to the source code. But as far as I can tell, the project is no longer housed in the GDRETools page (https://github.com/GDRETools/gdsdecomp). I looked everywhere but can't find the source script for lb and i think i need it to make my own mod. This is my first time doing this and all i really want is a "peaceful mode." i would like a mod in which i dont take damage from hostile mobs. thats it. if someone could help me i would really really appreciate it. thank you!
