A simple Python script for automatically updating Minecraft profiles in MultiMC/Prism Launcher.
This script ensures your instance always runs the latest release or snapshot version of Minecraft.

Download the script from one of the following sources:

• Codeberg Releases
• GitHub Releases

• Python installed on your system
• MultiMC or Prism Launcher installed

1. Ensure you have a Minecraft instance created in MultiMC/Prism Launcher.
2. Place the script in the root directory of your instance.
   This folder should also contain the mmc-pack.json file.
3. By default, the script updates to the latest release version of Minecraft.
   If you prefer to use the latest snapshot,
   change the USE_LATEST_RELEASE variable in the script from True to False,
   or use the snapshot argument during execution.

1. Open MultiMC/Prism Launcher.
2. Navigate to the instance settings of the instance you wish to auto update.
3. Go to the Settings tab, then open the Custom Commands sub-tab.
4. Add the following command as a pre-launch command:
   • Linux/Mac: python "$INST_DIR/mc-update.py"
   • Windows: python "$INST_DIR\\mc-update.py"
5. To update to the latest snapshot instead of the release,
   without changing the variable inside the script,
   add the word snapshot as argument:
   • Linux/Mac: python "$INST_DIR/mc-update.py" snapshot
   • Windows: python "$INST_DIR\\mc-update.py" snapshot

After setup, every time you start the instance in MultiMC/Prism Launcher,
the script will automatically update Minecraft to the latest version,
for release or snapshot and launch the game as usual.
