genetica

genetica

Genetica is a tool for using a simplified genetics system to generate inheritable traits for DnD characters.

Installation

You will need node and npm installed. Then run the command:

npm install -g genetica

Generate DNA from CLI

genetica

Follow the prompts for Race and Gender (optional) and your DNA is outputted with information on traits.

Module Usage

Require genetica into your file and create a new Genetica class.

const Genetica = require('genetica');

const genetica = new Genetica();

const opts = {
  gender: 'female',
  race: 'Dragonborn'
};

const DNA = genetica.generate(opts);

Simplified DNA System

Each generated character has a set of DNA with chromosomes. These chromosomes go to applying traits.

Each chromosome has two pairs with dice rolls based on the size of the chromosome: either d2, d4, d6, d8, d12, d20, or d100. So for example, Chromosome 1 has a size of d8 and the pair rolls for 5=8 which means the mother gave a roll of 5 and the father gave a roll of 8.

Rules

• Dominant/Recessive Genetic Rules: A rule of 3 means if 3 is the highest rolled then the trait applies. For example: a chromosome pair of 1=3 would mean the rule applies as 3 is the highest roll, but for a pair of 8=3 it would not.
• Co-dominant Genetic Rules: 1=3 means that the roll for the mother must be 1 and the father must be 3 in that order. A 3=1 would not apply the rule. This rule is checked BEFORE the dominant/recessive rules.
