Creating generative art

0. run yarn install in the root folder.
1. Create a traits folder and create a list of directories for the traits (i.e. background, shirt, sunglasses). Look at the example-traits for guidance
2. Run the following command to create a configuration file called traits-configuration.json: NOTE: The should be point to your traits folder you created in step 1

ts-node cli generate_art_configurations <directory>

The following file will be generated (based off of example-traits):

        }
      },
      "dark-green-face.png": 0.04,
      "flesh-face.png": 0.03,

    "mouth": {
      "block-mouth.png": 0.23,
      "smile-mouth.png": 0.09,
      "triangle-mouth.png": 0.68
    }
  },
  "order": ["background", "face", "eyes", "mouth"],
  "width": 1000,
  "height": 1000
}

3. Go through and customize the fields in the traits-configuration.json, such as name, symbol, description, creators, collection, width, and height.
4. After you have adjusted the configurations to your heart's content, you can run the following command to generate the JSON files along with the images.

ts-node cli create_generative_art -c <configuration_file_location> -n <number_of_images>

5. This will create an assets folder, with a set of the JSON and PNG files to make it work!

6. Note: Need to use a PSD instead of pngs? That's fine. You can have a PSD with two levels of layers - a top level like HEAD and then sublevel like "White Hat", "Black Hat", etc. Then you can create a traits configuration where the hash of each feature is named "HEAD" and then each layer shows up as a key with a probability, instead of PNGs. Then you can use the -o ability of the create_generative_art app to output just JSON files to the assets folder AND a whole array of arrays json to be used by the psd_layer_generator.py app to actually generate the images.

NOTE: Do not forget that "No Traits" is a special reserved key for this app.

To use the psd_layer_generator, do:

python psd_layer_generator.py -p ./traits.psd -o assets/ -t sets.json -e "FINISHERS" -n 0

Where sets is your output from the create generate command, and -e is an optional layer you toggle to true for every item. You may need this if you have extra finishing touches.

Remember with PSDs, for each layer folder to have a dummy trait at the top, or else the top layers won't render. [UNDISCLOSED BUG IN PSD READER] Also with PSDs, make sure your default visible layer is at the bottom of the folder. Another bug.
