mntm-asset-packer

An improved asset packer script to make the process of creating asset packs for the Momentum firmware easier. This script is designed to be backwards compatible with the original packer while adding new features for a better user experience.

Features

This improved packer adds several features over the original:

• Pack specific asset packs: No need to pack everything at once.
• Create command: Quickly scaffold the necessary file structure for a new asset pack.
• Automatic file conversion: Automatically convert and rename image frames for animations.
• Asset pack recovery: Recover PNGs and metadata from compiled asset packs. (Note: Font recovery is not yet implemented).
• Backwards compatibility: Works the same way as the original packer by default, so you can use it without changing your workflow.

Installation

With uv (recommended)

If you don't have uv installed, follow these instructions.

You can quickly run the script without installing, using this command:

uvx mntm-asset-packer help

To install, use this command:

uv tool install mntm-asset-packer
mntm-asset-packer help

With pip

To install with pip, you can use this command:

pip install mntm-asset-packer
mntm-asset-packer help

You may need to use pip3 instead of pip depending on your Python installation.

Standalone Mode

You can also copy the mntm_asset_packer.py file to your project directory and run it directly with Python. (Not recommended)

Setup venv

1. Clone this repository and navigate into its directory.
2. Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate

3. Install the required dependencies from requirements.txt:

   pip install -r requirements.txt
