Thanks for your comment.
Just to summerize the how it works :) A creature is just a DNA ( it’s 10 bytes randomly generated) After I have gene that is interpretation of one or some bytes, and it’s converted to part of creature. ( body, eye, ears, color). Each part of creature bring some capacity (bite, claws) or some attribute ( force, armor, lifesteal, etc.) and the creature is the sum of each of theses capacities and attributes !
So after it’s easy to cross 2 DNA, or just to mutate one by 5% for example, then I just have to regenerate the creature based on its DNA
Not sure it’s more clear :p
