Pokatlas decompiles PokeMMO's atlas spritesheet for easy modification.

Pokatlas

Pokatlas is python desktop application for decompiling the main.atlas and main.png spritesheet used in PokeMMO themes into separate sprites, allowing for easy replacement of the sprites, and recompiling the main.png image using the new sprites.

Pokatlas was created to save time updating the atlas file after each game update.

Requirements

• Python
• PySide6
• PyQtDarkTheme
• Pillow

Getting Started

Clone the source code with git or download it as a .zip file.

git clone https://github.com/Seth-Revz/Pokatlas.git
cd Pokatlas
pip install -r requirements.txt --ignore-requires-python
python pokatlas.py

pokatlas's Issues

Add option to create a new main.atlas file and new main.png sprite layout when saving.

Currently there are icons in the spritesheet that are used for multiple entries in main.atlas.
This creates the issue of if you replace these icons and they are different, keeping the same main.atlas will cause it to overwrite sprites.

Example:

The normal type monster icon is used for multiple languages.
You either overwrite for all, or none currently. They cannot be different
