I am trying to make a mutation that gives some effect. Kinda like how the “Long tail” mutation gives you extra dodge. But I was looking through the mutation.json file and couldn’t find anything that deals with that. So then I try’ed to use codeblocks and find it in the code. But to no avail. I would like to know where I could find such a thing. Me being new to modding in cataclysm I have almost no idea what I am doing.

ATM mutations are applied throughout the code wherever they would be having an effect. For example the check for dodge bonus mutations is int he dodge code, the one for what you can eat goes in the eating code, and so on. If you state what exactly you wanted the mutation to affect we could point you int eh right direction for which files to look into in the code, but it’s not one of the easily moddable things right now, sadly.

i2amroy got here first, but yeah. Long Tail is in player.cpp; the stinger tail shows up in melee.cpp and the Thick Tail shows up in both.

What’s up?
