Install mods for Paradox Interactive games locally (1)

😀

Install mods locally for games like: Stellaris, Hearts of Iron, Victoria

Locate the mod dir for your game(create one if not exist)

For newer games like victoria III, paste the mod dirs to the mod dir and you’re good to go

For older ones including: HOI and Stellaris, files with .mod extension(you can copy the descriptor.mod from the mod dir) are needed, the path to the corresponding mod is required(or the launcher cannot find it, you can copy mod paths from path bar in file explorer, but the separator should be changed to /).

This process(copy descriptor.mod and paste, change path inside the file and rename) can be automated with python script. Here is a reference.

python


import os
import shutil
import re


def process_mod_descriptors():
    # Get the current directory
    current_dir = os.getcwd()
    root_dir = current_dir

    # Create a log file for directories without descriptor.mod
    log_file_path = os.path.join(root_dir, "missing_descriptors.log")

    with open(log_file_path, "w") as log_file:
        # Iterate through all directories in the current directory
        for dir_name in os.listdir(current_dir):
            dir_path = os.path.join(current_dir, dir_name)

            # Check if it's a directory
            if os.path.isdir(dir_path):
                descriptor_path = os.path.join(dir_path, "descriptor.mod")

                # Check if descriptor.mod exists
                if os.path.exists(descriptor_path):
                    # Define the new filename for the copied descriptor
                    new_descriptor_name = f"{dir_name}.mod"
                    new_descriptor_path = os.path.join(root_dir, new_descriptor_name)

                    # Copy the descriptor.mod file
                    shutil.copy2(descriptor_path, new_descriptor_path)

                    # Append the path line to the copied file
                    with open(new_descriptor_path, "a") as mod_file:
                        mod_file.write(
                            f'\npath="C:/Users/Cinderella/Documents/Paradox Interactive/Hearts of Iron IV/mod/{dir_name}"'
                        )
                else:
                    # Log directories without descriptor.mod
                    log_file.write(f"{dir_name}\n")

    print(
        f"Processing complete. Check {log_file_path} for directories without descriptor.mod files."
    )


if __name__ == "__main__":
    process_mod_descriptors()

Restart the launcher and reload mods, if mods are installed correctly:

We can now add mods to playlist
