🎯 Why Change Unit Icons in Hoi4?

Changing unit icons in Hoi4 isn't just about aesthetics; it serves several practical purposes:

Enhanced Visual Clarity: Custom icons can provide clearer distinction among units, making it easier to manage large-scale operations.
Strategic Identification: Unique icons help in quickly identifying unit types, which can be critical during fast-paced strategic movements.

Delving into the Basics of Hoi4 Modding

Before diving into changing unit icons, it’s helpful to understand the basics of modding in Hearts of Iron IV.

Modding Overview

Modding Tools: Hoi4 offers modding support via the Paradox Launcher, allowing users to access and modify game files easily.
File Structure Knowledge: Familiarity with the game's file structure is crucial. Game files are generally located in the directory where Hoi4 is installed, and mod-related files can be found in the 'mod' folder within the Paradox Interactive directory in your computer's documents folder.

🛠️ Prerequisites: Setting Up for Icon Modding

Changing unit icons requires a few basic tools and an understanding of how game files are organized.

Tools You'll Need

Image Editing Software: Programs like Adobe Photoshop, GIMP, or any software supporting .DDS files are crucial for creating or altering icons.
DDS Plugin: If using software that doesn’t natively support .DDS files (e.g., older versions of Photoshop), you'll need a DDS plugin.
Text Editor: Basic tools like Notepad++, Sublime Text, or any software that allows simple text editing are essential for changing game configuration files.

File Preparation

Backup important game files to prevent loss of original content. This is a crucial step to avoid any unforeseen issues during modding.

Navigating the Hoi4 File Structure

Understanding how files are organized will streamline the process of changing unit icons.

Key Directories

GFX Folder: Contains graphical assets, including icons used for units.
Interface Files: These influence how the game renders icons within the user interface.

🖼️ Customizing Your Icons

Follow these steps to replace existing unit icons with your custom designs.

Designing Your Icon

Image Size and Format: Create your icon with a resolution that matches the existing unit icons - typically 64x64 pixels. Save it in .DDS format to ensure compatibility.
Aesthetics: Keep the design clear and distinct to ensure unit identification is easy during gameplay.

Implementing Custom Icons

Locate the Icon File: Navigate to the GFX folder within the Hearts of Iron IV directory.
Rename and Save: To ensure that your new icon replaces the existing icon correctly, rename your new icon file to match the original icon file.
Update Interface Files: Use a text editor to modify the appropriate interface file that specifies which GFX asset file corresponds to which in-game unit.

Advanced Modding: Creating a New Mod for Icons

For those looking to go beyond simple replacements and actively manage multiple custom icons, creating a mod through the Paradox Launcher is an excellent approach.

Step-by-Step Mod Creation

Access the Paradox Launcher: Open the Launcher and navigate to the 'Mods' section.
Create New Mod: Select "Create a mod" and provide relevant details such as Mod Name and Directory.
Incorporate Icons: Copy your customized DDS files into the gfx folder of your mod directory.
Editing the Mod Descriptor File: Ensure your mod descriptor file references the new icon files appropriately, enabling the game to read them once the mod is activated.

📝 Additional Tips and Considerations

Here are some tips to ensure a smooth modding process:

Keep Icons Consistent: Try to maintain a consistent visual style among your icons for easier recognition during gameplay.
Testing: After implementing any changes, run the game to ensure icons display correctly and without visual glitches.
