A python module for generating AI generated Minecraft resource packs. It utilizes the Craiyon image generating AI through the Craiyon.py API wrapper.

Create an instance of the PackGenerator class:

from pathlib import Path
from AIPackGenerator import PackGenerator, PackDecorator

pack_gen = PackGenerator(Path(Path.cwd() / 'source/textures'), 1000, 'output/pack_output', False)

This class takes 4 parameters:

1. The path to the source textures folder. The PackGenerator will use this to figure out the file names for all the textures, as well as the correct directories to place the textures in. This documentation will not go over how to get the base Minecraft textures; please refer to this article in the Minecraft wiki in order to firgure out how to extract the game's base textures.
2. The request amount limit. This defines how many requests to the Craiyon API can be active at one time.
3. The output folder. This defines the directory that the AI generated resource pack will output to. You do not have to define the current working directory as it automatically outputs there. Only define the folder name that you want it to output to.
4. Whether or not it will output to the console when generating. This defines whether or not the generator will output what it's currently generating to the console. Since it generates a lot of files at once, it is recommended to set this to False so that it doesn't spam the console.

In order to generate the pack, you need to call the generate() function:

pack_gen.generate('prefix', 0.25)

This function takes 2 parameters:

1. The prefix used when generating the pack. This means that the generator will attach the prefix before each prompt that is submitted to Craiyon (i.e. a prompt for a grass block, "grass block," becomes "prefix grass block," with prefix being whatever was input into the prefix parameter).
2. The time delay in seconds between each request.

Finally, to create a usable resource pack and add resource pack files such as the pack.mcmeta or pack.png files, an instance of PackDecorator needs to be created.

decorator = PackDecorator(Path(Path.cwd() / 'output/pack_output/')

The PackDecorator class only takes one parameter: the directory where the PackGenerator output all of its files.

Since Craiyon generates images that are 1024x1024, we need to resize them in order for Minecraft to recognize the pack as a valid pack. To do this, we can call the resize_images function in PackDecorator.

decorator.resize_images(128)

This function takes one parameter, which is the new image size. It is recommended that multiples of 2 (i.e. 16x, 32x, 64x, etc.) be used.

In order to add the pack.mcmeta and pack.png files to the resource pack, we need to call the gen_pack_files() function.

decorator.gen_pack_files("prefix", 12)

This function takes 2 parameters:

1. A prefix for generating pack.png. When the image is generated, Craiyon is prompted with "pack.png." If you choose to add a prefix, it will add that prefix before the "pack.png" in the prompt.
2. The resource pack format that will be set in the pack.mcmeta file. Mojang increases the format number when they make drastic changes to the resource pack format that would break compatability with previous game versions. Please refer to the Minecraft wiki in order to figure out which format number to use for your version.
