Important: There is a new repo for this code. https://github.com/HashLips/hashlips_art_engine
All the code in these repos was created and explained by HashLips on the main YouTube channel.

git clone https://github.com/HashLips/generative-art-node
yarn install
Create your different layers as folders in the 'layers' directory, and add all the layer assets in these directories. Optionally, append '_r' and '_sr' to the layer file names to make those layer files rare or super rare respectively.
Example: If you had an ball layer you would create a ball directory, and then a file might be called:
red_eye_ball_sr.png
red_eye_ball_r.png
red_eye_ball.png
Rarity is customizable in
src/config.js
.
Once you have all your layers, go into src/config.js
and update the layersOrder
array to be your layer folders name in order of the back layer to the front layer.
Example: If you were creating a portrait design, you might have a background, then a head, a mouth, eyes, eyewear, and then headwear, so your layersOrder
would look something like this:
const layersOrder = [
{ name: 'background', number: 1 },
{ name: 'ball', number: 2 },
{ name: 'eye color', number: 12 },
{ name: 'iris', number: 3 },
{ name: 'shine', number: 1 },
{ name: 'bottom lid', number: 3 },
{ name: 'top lid', number: 3 },
];
The name
of each layer object represents the name of the folder (in /layers/
) that the images reside in. The number
of each layer object represents the total number of image files you want to select from (possibly including blanks.) For instance, if you have three images in a layer folder and want to pick one of those each time, the number
should be 3
. If you have a single image in a layer that you want to increase the rarity of to 1 in 100, the number
for that layer should be 100
. In this case, 99 times out of 100, you will get a completely transparent layer.
Then optionally, update your format
size, ie the outputted image size, and the defaultEdition, which is the amount of variation outputted.
When you are all ready, run the following command and your outputted art will be in the build
directory:
npm run build
