Usage

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
